Class JdbcAclService

java.lang.Object

org.springframework.security.acls.jdbc.JdbcAclService

All Implemented Interfaces:

AclService

Direct Known Subclasses:

JdbcMutableAclService

public class JdbcAclService
extends java.lang.Object
implements AclService

Simple JDBC-based implementation of AclService.

Requires the "dirty" flags in AclImpl and AccessControlEntryImpl to be set, so that the implementation can detect changed parameters easily.

JdbcAclService

public JdbcAclService(javax.sql.DataSource dataSource,
                      LookupStrategy lookupStrategy)

Method Detail

findChildren

public java.util.List<ObjectIdentity> findChildren(ObjectIdentity parentIdentity)

Description copied from interface: AclService

Locates all object identities that use the specified parent. This is useful for administration tools.

Specified by:

findChildren in interface AclService

Parameters:

parentIdentity - to locate children of

Returns:

the children (or null if none were found)

readAclById

public Acl readAclById(ObjectIdentity object,
                       java.util.List<Sid> sids)
                throws NotFoundException

Description copied from interface: AclService

Same as AclService.readAclsById(List, List) except it returns only a single Acl.

Specified by:

readAclById in interface AclService

Parameters:

object - to locate an Acl for

sids - the security identities for which Acl information is required (may be null to denote all entries)

Returns:

the Acl for the requested ObjectIdentity (never null)

Throws:

NotFoundException - if an Acl was not found for the requested ObjectIdentity

readAclById

public Acl readAclById(ObjectIdentity object)
                throws NotFoundException

Description copied from interface: AclService

Same as AclService.readAclsById(List) except it returns only a single Acl.

This method should not be called as it does not leverage the underlying implementation's potential ability to filter Acl entries based on a Sid parameter.

Specified by:

readAclById in interface AclService

Parameters:

object - to locate an Acl for

Returns:

the Acl for the requested ObjectIdentity (never null)

Throws:

NotFoundException - if an Acl was not found for the requested ObjectIdentity

readAclsById

public java.util.Map<ObjectIdentity,Acl> readAclsById(java.util.List<ObjectIdentity> objects)
                                               throws NotFoundException

Description copied from interface: AclService

Obtains all the Acls that apply for the passed Objects.

The returned map is keyed on the passed objects, with the values being the Acl instances. Any unknown objects will not have a map key.

Specified by:

readAclsById in interface AclService

Parameters:

objects - the objects to find Acl information for

Returns:

a map with exactly one element for each ObjectIdentity passed as an argument (never null)

Throws:

NotFoundException - if an Acl was not found for each requested ObjectIdentity

readAclsById

public java.util.Map<ObjectIdentity,Acl> readAclsById(java.util.List<ObjectIdentity> objects,
                                                      java.util.List<Sid> sids)
                                               throws NotFoundException

Description copied from interface: AclService

Obtains all the Acls that apply for the passed Objects, but only for the security identifies passed.

Implementations MAY provide a subset of the ACLs via this method although this is NOT a requirement. This is intended to allow performance optimisations within implementations. Callers should therefore use this method in preference to the alternative overloaded version which does not have performance optimisation opportunities.

The returned map is keyed on the passed objects, with the values being the Acl instances. Any unknown objects (or objects for which the interested Sids do not have entries) will not have a map key.

Specified by:

readAclsById in interface AclService

Parameters:

objects - the objects to find Acl information for

sids - the security identities for which Acl information is required (may be null to denote all entries)

Returns:

a map with exactly one element for each ObjectIdentity passed as an argument (never null)

Throws:

NotFoundException - if an Acl was not found for each requested ObjectIdentity

setFindChildrenQuery

public void setFindChildrenQuery(java.lang.String findChildrenSql)

Allows customization of the SQL query used to find child object identities.

Parameters:

findChildrenSql -

setAclClassIdSupported

public void setAclClassIdSupported(boolean aclClassIdSupported)

setAclClassIdUtils

public void setAclClassIdUtils(org.springframework.security.acls.jdbc.AclClassIdUtils aclClassIdUtils)

isAclClassIdSupported

protected boolean isAclClassIdSupported()
