public abstract class AuthorizingSecurityManager extends AuthenticatingSecurityManager
Shiro support of a SecurityManager class hierarchy that delegates all authorization (access control) operations to a wrapped Authorizer instance. That is, this class implements all the Authorizer methods in the SecurityManager interface, but in reality, those methods are merely passthrough calls to the underlying 'real' Authorizer instance.

All remaining SecurityManager methods not covered by this class or its parents (mostly Session support) are left to be implemented by subclasses.

In keeping with the other classes in this hierarchy and Shiro's desire to minimize configuration whenever possible, suitable default instances for all dependencies will be created upon instantiation.

    • getAuthorizer

      public Authorizer getAuthorizer()
      Returns the underlying wrapped Authorizer instance to which this SecurityManager implementation delegates all of its authorization calls.
      Returns:
      the wrapped Authorizer used by this SecurityManager implementation.

    • setAuthorizer

      public void setAuthorizer(Authorizer authorizer)
      Sets the underlying Authorizer instance to which this SecurityManager implementation will delegate all of its authorization calls.
      Parameters:
      authorizer - the Authorizer this SecurityManager should wrap and delegate all of its authorization calls to.

    • afterRealmsSet

      protected void afterRealmsSet()
      First calls super.afterRealmsSet() and then sets these same Realm objects on this instance's wrapped Authorizer.

      The setting of realms the Authorizer will only occur if it is an instance of ModularRealmAuthorizer, that is: 

       if ( this.authorizer instanceof ModularRealmAuthorizer ) {
     ((ModularRealmAuthorizer)this.authorizer).setRealms(realms);
 }

    • destroy

      public void destroy()
      Description copied from class: CachingSecurityManager
      Destroys the cacheManager via LifecycleUtils.destroy.
      Specified by:
      destroy in interface org.apache.shiro.lang.util.Destroyable
      Overrides:

    • isPermitted

      public boolean isPermitted(PrincipalCollection principals, String permissionString)
      Description copied from interface: Authorizer
      Returns true if the corresponding subject/user is permitted to perform an action or access a resource summarized by the specified permission string.

      This is an overloaded method for the corresponding type-safe Permission variant. Please see the class-level JavaDoc for more information on these String-based permission methods.

      Parameters:
      principals - the application-specific subject/user identifier.
      permissionString - the String representation of a Permission that is being checked.
      Returns:
      true if the corresponding Subject/user is permitted, false otherwise.
      See Also:

    • isPermitted

      public boolean isPermitted(PrincipalCollection principals, Permission permission)
      Description copied from interface: Authorizer
      Returns true if the corresponding subject/user is permitted to perform an action or access a resource summarized by the specified permission.

      More specifically, this method determines if any Permissions associated with the subject imply the specified permission.

      Parameters:
      principals - the application-specific subject/user identifier.
      permission - the permission that is being checked.
      Returns:
      true if the corresponding Subject/user is permitted, false otherwise.

    • isPermitted

      public boolean[] isPermitted(PrincipalCollection principals, String... permissions)
      Description copied from interface: Authorizer
      Checks if the corresponding Subject implies the given permission strings and returns a boolean array indicating which permissions are implied.

      This is an overloaded method for the corresponding type-safe Permission variant. Please see the class-level JavaDoc for more information on these String-based permission methods.

      Parameters:
      principals - the application-specific subject/user identifier.
      permissions - the String representations of the Permissions that are being checked.
      Returns:
      an array of booleans whose indices correspond to the index of the permissions in the given list. A true value at an index indicates the user is permitted for for the associated Permission string in the list. A false value at an index indicates otherwise.

    • isPermitted

      public boolean[] isPermitted(PrincipalCollection principals, List<Permission> permissions)
      Description copied from interface: Authorizer
      Checks if the corresponding Subject/user implies the given Permissions and returns a boolean array indicating which permissions are implied.

      More specifically, this method should determine if each Permission in the array is implied by permissions already associated with the subject.

      This is primarily a performance-enhancing method to help reduce the number of Authorizer.isPermitted(org.apache.shiro.subject.PrincipalCollection, java.lang.String) invocations over the wire in client/server systems.

      Parameters:
      principals - the application-specific subject/user identifier.
      permissions - the permissions that are being checked.
      Returns:
      an array of booleans whose indices correspond to the index of the permissions in the given list. A true value at an index indicates the user is permitted for for the associated Permission object in the list. A false value at an index indicates otherwise.
