Interface RunAsManager

  • All Known Implementing Classes:
    RunAsManagerImpl
    @Deprecated
public interface RunAsManager
    Deprecated.
    Authentication is now separated from authorization in Spring Security. This class is only used by now-deprecated components. There is not yet an equivalent replacement in Spring Security.
    Creates a new temporary Authentication object for the current secure object invocation only.

    This interface permits implementations to replace the Authentication object that applies to the current secure object invocation only. The AbstractSecurityInterceptor will replace the Authentication object held in the SecurityContext for the duration of the secure object callback only, returning it to the original Authentication object when the callback ends.

    This is provided so that systems with two layers of objects can be established. One layer is public facing and has normal secure methods with the granted authorities expected to be held by external callers. The other layer is private, and is only expected to be called by objects within the public facing layer. The objects in this private layer still need security (otherwise they would be public methods) and they also need security in such a manner that prevents them being called directly by external callers. The objects in the private layer would be configured to require granted authorities never granted to external callers. The RunAsManager interface provides a mechanism to elevate security in this manner.

    It is expected implementations will provide a corresponding concrete Authentication and AuthenticationProvider so that the replacement Authentication object can be authenticated. Some form of security will need to be implemented to ensure the AuthenticationProvider only accepts Authentication objects created by an authorized concrete implementation of RunAsManager.

      • buildRunAs

        Authentication buildRunAs​(Authentication authentication,
                          java.lang.Object object,
                          java.util.Collection<ConfigAttribute> attributes)
        Deprecated.
        Returns a replacement Authentication object for the current secure object invocation, or null if replacement not required.
        Parameters:
        authentication - the caller invoking the secure object
        object - the secured object being called
        attributes - the configuration attributes associated with the secure object being invoked
        Returns:
        a replacement object to be used for duration of the secure object invocation, or null if the Authentication should be left as is

      • supports

        boolean supports​(ConfigAttribute attribute)
        Deprecated.
        Indicates whether this RunAsManager is able to process the passed ConfigAttribute.

        This allows the AbstractSecurityInterceptor to check every configuration attribute can be consumed by the configured AccessDecisionManager and/or RunAsManager and/or AfterInvocationManager.

        Parameters:
        attribute - a configuration attribute that has been configured against the AbstractSecurityInterceptor
        Returns:
        true if this RunAsManager can support the passed configuration attribute

      • supports

        boolean supports​(java.lang.Class<?> clazz)
        Deprecated.
        Indicates whether the RunAsManager implementation is able to provide run-as replacement for the indicated secure object type.
        Parameters:
        clazz - the class that is being queried
        Returns:
        true if the implementation can process the indicated class
