Interface ResourceResolver
- All Superinterfaces:
Adaptable,AutoCloseable,Closeable
- All Known Implementing Classes:
ResourceResolverWrapper
ResourceResolver defines the API which may be used
to resolve Resource objects and
work with such resources like creating, editing or updating them.
The resource resolver is available to the request processing servlet
through the
SlingHttpServletRequest.getResourceResolver()
method. A resource resolver can also be created through the
ResourceResolverFactory service.
The ResourceResolver is also an Adaptable to get
adapters to other types. A JCR based resource resolver might support adapting
to the JCR Session used by the resolver to access the JCR Repository.
A ResourceResolver is generally not thread safe! As a
consequence, an application which uses the resolver, its returned resources
and/or objects resulting from adapting either the resolver or a resource,
must provide proper synchronization to ensure no more than one thread
concurrently operates against a single resolver, resource or resulting
objects.
Accessing Resources
This interface defines two kinds of methods to access resources: The
resolve methods and the getResource methods. The
difference lies in the algorithm applied to find the requested resource and
in the behavior in case a resource cannot be found:
| Method Kind | Access Algorithm | Missing Resource |
|---|---|---|
| resolve | Path is always assumed to be absolute. Uses elaborate resource resolution algorithm. This kind of method is intended to resolve request URLs to resources. | Returns NonExistingResource |
| getResource | Directly access resources with absolute path. For relative paths, the
search path is applied. This method is intended to
be used by request processing scripts to access further resources as
required. |
Returns null |
Resource Handling
A resource resolver provides various methods to manage resources. All changes are transient and require to commit them at the end.
create(Resource, String, Map)for creating a new resource.delete(Resource)to delete a resource.Adaptable.adaptTo(Class)allows to adapt a resource to aModifiableValueMapto update a resource.move(String, String)to move resources.copy(String, String)to copy resources.commit()commits all staged changes.revert()reverts all staged changes.
The resource tree accessible through the resource resolver is backed by one or
more ResourceProviders. In
general it is advisable to limit transient changes to a single resource provider.
The commit() is not using a two phase commit, therefore if there
is more than one resource provider involved and one of them fails in persisting,
changes already committed to other providers are not reverted.
External changes
Changes which happen outside of the Resource API provided by Sling are not required to be reflected immediately within an already opened ResourceResolver and its associated resources. For example, if the ResourceResolver is backed by a JCR implementation, any changes within the JCR session (which is an implementation detail of the respective ResourceResolver implementation) are not required to be reflected within its Resource Resolver.
Lifecycle
A Resource Resolver has a life cycle which begins with the creation of the
Resource Resolver using any of the factory methods and ends with calling the
close() method. It is very important to call the close()
method once the resource resolver is not used any more to ensure any system
resources are properly cleaned up.
A Resource Resolver may also be closed implicitly if the ResourceResolverFactory
which was used to create this resolver is no longer active.
To check whether a Resource Resolver can still be used, the isLive()
method can be called.
A ResourceResolver is only valid for as long as the
ResourceResolverFactory that created this instance exists. The
same applies in general to all objects returned by this instance,
especially for all resources. If the ResourceResolverFactory
does not exist anymore, the resource resolver instances becomes invalid.
Resource Resolver Attributes
The authentication info properties provided to the
ResourceResolverFactory.getResourceResolver(Map),
ResourceResolverFactory.getAdministrativeResourceResolver(Map), or
clone(Map) are available through the getAttributeNames()
and getAttribute(String) methods with the exception of security
sensitive properties like ResourceResolverFactory.PASSWORD which is
not exposed.

resolve
@NotNull @NotNull Resource resolve(@NotNull @NotNull javax.servlet.http.HttpServletRequest request, @NotNull @NotNull String absPath) Resolves the resource from the givenabsPathoptionally takingHttpServletRequestinto account, such as the value of theHostrequest header. Returns aNonExistingResourceif the path cannot be resolved to an existing and accessible resource.The difference between this method and the
resolve(String)method is, that this method may take request properties like the scheme, the host header or request parameters into account to resolve the resource.- Parameters:
request- The http servlet request object providing more hints at how to resolve theabsPath. This parameter may benullin which case the implementation should use reasonable defaults.absPath- The absolute path to be resolved to a resource. If this parameter isnull, it is assumed to address the root of the resource tree. If the path is relative it is assumed relative to the root, that is a slash is prepended to the path before resolving it.- Returns:
- The
Resourceaddressed by theabsPathor aNonExistingResourceif no such resource can be resolved. - Throws:
SlingException- Or a subclass thereof may be thrown if an error occurs trying to resolve the resource.IllegalStateException- if this resource resolver has already beenclosed.- Since:
- 2.0.4 (Sling API Bundle 2.0.4)
- See Also:

resolve
Resolves the resource from the given absolute path. Returns aNonExistingResourceif the path cannot be resolved to an existing and accessible resource.This method is intended to apply the same algorithm to the absolute path as is used by the
resolve(HttpServletRequest)method except for cases where the latter uses request property such as request headers or request parameters to resolve a resource.It is ok for the implementation of this method to just call the
resolve(HttpServletRequest, String)method withnullas the request argument.- Parameters:
absPath- The absolute path to be resolved to a resource. If this parameter isnull, it is assumed to address the root of the resource tree. If the path is relative it is assumed relative to the root, that is a slash is prepended to the path before resolving it.- Returns:
- The
Resourceaddressed by theabsPathor aNonExistingResourceif no such resource can be resolved. - Throws:
SlingException- Or a subclass thereof may be thrown if an error occurs trying to resolve the resource.IllegalStateException- if this resource resolver has already beenclosed.- See Also:
-
resolve
@Deprecated @NotNull @NotNull Resource resolve(@NotNull @NotNull javax.servlet.http.HttpServletRequest request) Deprecated.as of 2.0.4, useresolve(HttpServletRequest, String)instead.Resolves the resource from the givenHttpServletRequest. Returns aNonExistingResourceif the path cannot be resolved to an existing and accessible resource.This method is deprecated as of API version 2.0.4 and should not be used anymore. Implementations are expected to implement this method calling the
resolve(HttpServletRequest, String)where theabsPathargument is the result of calling thegetPathInfo()on therequestobject.- Parameters:
request- The http servlet request object used to resolve the resource for. This must not benull.- Returns:
- The
Resourceaddressed byHttpServletRequest.getPathInfo()or aNonExistingResourceif no such resource can be resolved. - Throws:
NullPointerException- Ifrequestisnull.SlingException- Or a subclass thereof may be thrown if an error occurs trying to resolve the resource.IllegalStateException- if this resource resolver has already beenclosed.- See Also:
-
map
Returns a (request) path mapped from the (resource) path applying the reverse mapping used by theresolve(String)such that when the path is given to theresolve(String)method the same resource is returned.Note, that technically the
resourcePathneed not refer to an existing resource. This method just applies the mappings and returns the resulting string. If theresourcePathdoes not address an existing resource roundtripping may of course not work and callingresolve(String)with the path returned may returnnull.This method is intended as the reverse operation of the
resolve(String)method.This method also does percent-encoding before returning the (request) path (with charset UTF-8). Due to this calling this method multiple times in a nested fashion might lead to an invalid (request) path which can subsequently not be resolved via
resolve(String).- Parameters:
resourcePath- The path for which to return a mapped path.- Returns:
- The mapped path or
resourcePathin case no mapping is found. - Throws:
IllegalStateException- if this resource resolver has already beenclosed.- See Also:
-
map
@NotNull @NotNull String map(@NotNull @NotNull javax.servlet.http.HttpServletRequest request, @NotNull @NotNull String resourcePath) Returns an URL mapped from the (resource) path applying the reverse mapping used by theresolve(HttpServletRequest, String)such that when the path is given to theresolve(HttpServletRequest, String)method the same resource is returned.Note, that technically the
resourcePathneed not refer to an existing resource. This method just applies the mappings and returns the resulting string. If theresourcePathdoes not address an existing resource roundtripping may of course not work and callingresolve(HttpServletRequest, String)with the path returned may returnnull.This method is intended as the reverse operation of the
resolve(HttpServletRequest, String)method. As such the URL returned is expected to be an absolute URL including scheme, host, any servlet context path and the actual path used to resolve the resource.This method also does percent-encoding before returning the URL (with charset UTF-8). Due to this calling this method multiple times in a nested fashion might lead to an invalid URL which can subsequently not be resolved via
resolve(String).- Parameters:
request- The http servlet request object which may be used to apply more mapping functionality.resourcePath- The path for which to return a mapped path.- Returns:
- The mapped URL or
resourcePathin case no mapping is found. - Throws:
IllegalStateException- if this resource resolver has already beenclosed.- Since:
- 2.0.4 (Sling API Bundle 2.0.4)
- See Also:

getResource
Returns aResourceobject for data located at the given path.This specification does not define the location for resources or the semantics for resource paths. For an implementation reading content from a Java Content Repository, the path could be a
javax.jcr.Itempath from which the resource object is loaded. In contrast to theresolve(String)method, this method does not apply any logic to the path, so the path is used as-is to fetch the content.- Parameters:
path- The absolute path to the resource object to be loaded. The path may contain relative path specifiers like.(current location) and..(parent location), which are resolved by this method. If the path is relative, that is the first character is not a slash, implementations are expected to apply a search path algorithm to resolve the relative path to a resource.- Returns:
- The
Resourceobject loaded from the path ornullif the path does not resolve to a resource. - Throws:
SlingException- If an error occurs trying to load the resource object from the path.IllegalStateException- if this resource resolver has already beenclosed.
-
getResource
Returns aResourceobject for data located at the given path.This specification does not define the location for resources or the semantics for resource paths. For an implementation reading content from a Java Content Repository, the path could be a
javax.jcr.Itempath from which the resource object is loaded.- Parameters:
base- The baseResourceagainst which a relative path argument given bypathis resolved. This parameter may benullif thepathis known to be absolute.path- The path to the resource object to be loaded. If the path is relative, i.e. does not start with a slash (/), the resource relative to the givenbaseresource is returned. The path may contain relative path specifiers like.(current location) and..(parent location), which are resolved by this method.- Returns:
- The
Resourceobject loaded from the path ornullif the path does not resolve to a resource. - Throws:
SlingException- If an error occurs trying to load the resource object from the path or ifbaseisnullandpathis relative.IllegalStateException- if this resource resolver has already beenclosed.
-
getSearchPath
Returns the search path used by thegetResource(String)method to search for resources by relative path. If no search path is set an array with the single value "/" is returned.The returned array of strings is a copy of the internal value, so modifications to this array have no influence on the operation of the ResourceResolver.
The search path of a resource resolver never changes during the lifetime of the resource resolver. Therefore clients may call this method once and use the stored value together with this resource resolver.
Each entry in the array is an absolute path terminated with a slash character. Thus to create an absolute path from a search path entry and a relative path, the search path entry and relative path may just be concatenated.
- Returns:
- The array of search paths
- Throws:
IllegalStateException- if this resource resolver has already beenclosed.
-
listChildren
Returns anIteratorofResourceobjects loaded from the children of the givenResource.This specification does not define what the term "child" means. This is left to the implementation to define. For example an implementation reading content from a Java Content Repository, the children could be the
Resourceobjects loaded from child items of theItemof the givenResource.- Parameters:
parent- TheResourcewhose children are requested.- Returns:
- An
IteratorofResourceobjects. - Throws:
NullPointerException- Ifparentisnull.SlingException- If any error occurs acquiring the child resource iterator.IllegalStateException- if this resource resolver has already beenclosed.
-
getParent
Returns the parent resource of this resource.This method is implemented by getting the parent resource path first calling the
ResourceUtil.getParent(String)method and then to retrieve that resource.- Parameters:
child- TheResourcewhose parent is requested.- Returns:
- The parent resource or
null. - Throws:
NullPointerException- Ifchildisnull.SlingException- If any error occurs acquiring the parent resource.IllegalStateException- if this resource resolver has already beenclosed.- Since:
- 2.9 (Sling API Bundle 2.11.0)
-
getChildren
Returns anIterableofResourceobjects loaded from the children of the givenResource.This specification does not define what the term "child" means. This is left to the implementation to define. For example an implementation reading content from a Java Content Repository, the children could be the

parent- TheResourcewhose children are requested.- Returns:
- An
IterableofResourceobjects. - Throws:
NullPointerException- Ifparentisnull.SlingException- If any error occurs acquiring the child resource iterator.IllegalStateException- if this resource resolver has already beenclosed.- Since:
- 2.2 (Sling API Bundle 2.2.0)
-
findResources
Searches for resources using the given query formulated in the given language.The semantic meaning of the query and language depend on the actual implementation and storage used for the resources. For JCR repository being used as storage, the query and language parameters are used to create a JCR
Querythrough theQueryManager. The result returned is then based on theNodeIteratorprovided by the query result.- Parameters:
query- The query string to use to find the resources.language- The language in which the query is formulated. The language should always be specified. However for compatibility with older version, if no language is specified, "xpath" is used.- Returns:
- An
IteratorofResourceobjects matching the query. - Throws:

-
queryResources
@NotNull @NotNull Iterator<Map<String,Object>> queryResources(@NotNull @NotNull String query, String language) Queries the storage using the given query formulated in the given language.The semantic meaning of the query and language depend on the actual implementation and storage used for the resources. For JCR repository being used as storage, the query and language parameters are used to create a JCR
Querythrough theQueryManager. The result returned is then based on theRowIteratorprovided by the query result. The map returned for each row is indexed by the column name and the column value is the JCRValueobject converted into the respective Java object, such asBooleanfor a value of property type Boolean.- Parameters:
query- The query string to use to find the resources.language- The language in which the query is formulated. The language should always be specified. However for compatibility with older version, if no language is specified, "xpath" is used.- Returns:
- An
IteratorofMapinstances providing access to the query result. - Throws:
QuerySyntaxException- If the query is not syntactically correct according to the query language indicator.SlingException- If an error occurs querying for the resources.IllegalStateException- if this resource resolver has already beenclosed.

boolean isLive()Returnstrueif this resource resolver is still usable. This method tests different things like if it has not been closed yet or if any of the used resource providers is not usable anymore.Unlike the other methods defined in this interface, this method will never throw an exception even after the resource resolver has been
closed.- Returns:
trueif the resource resolver is still usable. Once the resource resolver has been closed or a used resource provider has been unregistered, this method returnsfalse.- Since:
- 2.1 (Sling API Bundle 2.1.0)
-
close
void close()Close this resource resolver. This method should be called by clients when the resource resolver is not used anymore. Once this method has been called, the resource resolver is considered unusable and will throw exceptions if still used - with the exception of this method, which can be called several times with no ill effects. A resolver may also be closed implicitly in case when theResourceResolverFactorywhich was used to create this resolver is no longer active or any of the used resource providers is no longer active. All objects in the map maintained bygetPropertyMap()implementing theCloseableinterface, will be closed by callingCloseable#close()on each of them. Any exception thrown by this call will be ignored.

copy
This method copies the subgraph rooted at, and including, the resource atsrcAbsPathto the new location atdestAbsPathand adds it as a child node of the resource atdestAbsPath. If the copy operation is within a single resource provider, the resource provider can use an optimized copy operation. Otherwise the resource resolver copies resources from one provider to another. The resource atdestAbsPathneeds to exist, if not aPersistenceExceptionis thrown. If a child resource with the same name already exists atdestAbsPathaPersistenceExceptionis thrown. If the resource atsrcAbsPathdoes not exist, aPersistenceExceptionis thrown. The changes are transient and require a call tocommit()for persisting.- Parameters:

-
move
This method moves the subgraph rooted at, and including, the resource atsrcAbsPathto the new location atdestAbsPathand adds it as a child node of the resource atdestAbsPath. If the move operation is within a single resource provider, the resource provider can use an optimized move operation. Otherwise the resource resolver moves resources from one provider to another. The resource atdestAbsPathneeds to exist, if not aPersistenceExceptionis thrown. If a child resource with the same name already exists atdestAbsPathaPersistenceExceptionis thrown. If the resource atsrcAbsPathdoes not exist, aPersistenceExceptionis thrown. The changes are transient and require a call tocommit()for persisting.- Parameters:

-
getPropertyMap
Returns a mutable map to store temporary objects. This map is suited to store objects which share the same lifecycle as the resource resolver. The resource resolver itself does not use this map. The resource resolver will clear the map duringclose(), so afterwards the map is empty. If a stored value implements theCloseableinterface, the ResourceResolver will invoke theclosemethod} of the value before clearing the map. Clients should not use this map to store objects which have a lifecycle beyond the resource resolver. Any object stored into this map after the resource resolver has been closed will not be closed. The returned map is not thread-safe.- Returns:
- the property map
