    public abstract class AbstractSecurityInterceptor
extends java.lang.Object
implements org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationEventPublisherAware, org.springframework.context.MessageSourceAware
    Abstract class that implements security interception for secure objects.

    The AbstractSecurityInterceptor will ensure the proper startup configuration of the security interceptor. It will also implement the proper handling of secure object invocations, namely:

    1. Obtain the Authentication object from the SecurityContextHolder.
    2. Determine if the request relates to a secured or public invocation by looking up the secure object request against the SecurityMetadataSource.
    3. For an invocation that is secured (there is a list of ConfigAttributes for the secure object invocation):
      1. If either the Authentication.isAuthenticated() returns false, or the alwaysReauthenticate is true, authenticate the request against the configured AuthenticationManager. When authenticated, replace the Authentication object on the SecurityContextHolder with the returned value.
      2. Authorize the request against the configured AccessDecisionManager.
      3. Perform any run-as replacement via the configured RunAsManager.
      4. Pass control back to the concrete subclass, which will actually proceed with executing the object. A InterceptorStatusToken is returned so that after the subclass has finished proceeding with execution of the object, its finally clause can ensure the AbstractSecurityInterceptor is re-called and tidies up correctly using finallyInvocation(InterceptorStatusToken).
      5. The concrete subclass will re-call the AbstractSecurityInterceptor via the afterInvocation(InterceptorStatusToken, Object) method.
      6. If the RunAsManager replaced the Authentication object, return the SecurityContextHolder to the object that existed after the call to AuthenticationManager.
      7. If an AfterInvocationManager is defined, invoke the invocation manager and allow it to replace the object due to be returned to the caller.
    4. For an invocation that is public (there are no ConfigAttributes for the secure object invocation):
      1. As described above, the concrete subclass will be returned an InterceptorStatusToken which is subsequently re-presented to the AbstractSecurityInterceptor after the secure object has been executed. The AbstractSecurityInterceptor will take no further action when its afterInvocation(InterceptorStatusToken, Object) is called.
    5. Control again returns to the concrete subclass, along with the Object that should be returned to the caller. The subclass will then return that result or exception to the original caller.

      • afterPropertiesSet

        public void afterPropertiesSet()
        Specified by:
        afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

      • finallyInvocation

        protected void finallyInvocation​(InterceptorStatusToken token)
        Cleans up the work of the AbstractSecurityInterceptor after the secure object invocation has been completed. This method should be invoked after the secure object invocation and before afterInvocation regardless of the secure object invocation returning successfully (i.e. it should be done in a finally block).
        Parameters:
        token - as returned by the beforeInvocation(Object) method

      • afterInvocation

        protected java.lang.Object afterInvocation​(InterceptorStatusToken token,
                                           java.lang.Object returnedObject)
        Completes the work of the AbstractSecurityInterceptor after the secure object invocation has been completed.
        Parameters:
        token - as returned by the beforeInvocation(Object) method
        returnedObject - any object returned from the secure object invocation (may be null)
        Returns:
        the object the secure object invocation should ultimately return to its caller (may be null)

      • getSecureObjectClass

        public abstract java.lang.Class<?> getSecureObjectClass()
        Indicates the type of secure objects the subclass will be presenting to the abstract parent for processing. This is used to ensure collaborators wired to the AbstractSecurityInterceptor all support the indicated secure object class.
        Returns:
        the type of secure object the subclass provides services for

      • isAlwaysReauthenticate

        public boolean isAlwaysReauthenticate()

      • isRejectPublicInvocations

        public boolean isRejectPublicInvocations()

      • isValidateConfigAttributes

        public boolean isValidateConfigAttributes()

      • setAccessDecisionManager

        public void setAccessDecisionManager​(AccessDecisionManager accessDecisionManager)

      • setAfterInvocationManager

        public void setAfterInvocationManager​(AfterInvocationManager afterInvocationManager)

      • setAlwaysReauthenticate

        public void setAlwaysReauthenticate​(boolean alwaysReauthenticate)
        Indicates whether the AbstractSecurityInterceptor should ignore the Authentication.isAuthenticated() property. Defaults to false, meaning by default the Authentication.isAuthenticated() property is trusted and re-authentication will not occur if the principal has already been authenticated.
        Parameters:
        alwaysReauthenticate - true to force AbstractSecurityInterceptor to disregard the value of Authentication.isAuthenticated() and always re-authenticate the request (defaults to false).

      • setApplicationEventPublisher

        public void setApplicationEventPublisher​(org.springframework.context.ApplicationEventPublisher applicationEventPublisher)
        Specified by:
        setApplicationEventPublisher in interface org.springframework.context.ApplicationEventPublisherAware

      • setMessageSource

        public void setMessageSource​(org.springframework.context.MessageSource messageSource)
        Specified by:
        setMessageSource in interface org.springframework.context.MessageSourceAware

      • setPublishAuthorizationSuccess

        public void setPublishAuthorizationSuccess​(boolean publishAuthorizationSuccess)
        Only AuthorizationFailureEvent will be published. If you set this property to true, AuthorizedEvents will also be published.
        Parameters:
        publishAuthorizationSuccess - default value is false

      • setRejectPublicInvocations

        public void setRejectPublicInvocations​(boolean rejectPublicInvocations)
        By rejecting public invocations (and setting this property to true), essentially you are ensuring that every secure object invocation advised by AbstractSecurityInterceptor has a configuration attribute defined. This is useful to ensure a "fail safe" mode where undeclared secure objects will be rejected and configuration omissions detected early. An IllegalArgumentException will be thrown by the AbstractSecurityInterceptor if you set this property to true and an attempt is made to invoke a secure object that has no configuration attributes.
        Parameters:
        rejectPublicInvocations - set to true to reject invocations of secure objects that have no configuration attributes (by default it is false which treats undeclared secure objects as "public" or unauthorized).

        public void setRunAsManager​(RunAsManager runAsManager)

      • setValidateConfigAttributes
