public class DelegatingIntroductionInterceptor
extends IntroductionInfoSupport
implements IntroductionInterceptor

Convenient implementation of the IntroductionInterceptor interface.

Subclasses merely need to extend this class and implement the interfaces to be introduced themselves. In this case the delegate is the subclass instance itself. Alternatively a separate delegate may implement the interface, and be set via the delegate bean property.

Delegates or subclasses may implement any number of interfaces. All interfaces except IntroductionInterceptor are picked up from the subclass or delegate by default.

The suppressInterface method can be used to suppress interfaces implemented by the delegate but which should not be introduced to the owning AOP proxy.

An instance of this class is serializable if the delegate is.

构造器详细资料

DelegatingIntroductionInterceptor

public DelegatingIntroductionInterceptor(Object delegate)

Construct a new DelegatingIntroductionInterceptor, providing a delegate that implements the interfaces to be introduced.

参数:

delegate - the delegate that implements the introduced interfaces

DelegatingIntroductionInterceptor

protected DelegatingIntroductionInterceptor()

Construct a new DelegatingIntroductionInterceptor. The delegate will be the subclass, which must implement additional interfaces.

方法详细资料

invoke

@Nullable
public Object invoke(MethodInvocation mi)
                         throws Throwable

Subclasses may need to override this if they want to perform custom behaviour in around advice. However, subclasses should invoke this method, which handles introduced interfaces and forwarding to the target.

指定者:

invoke 在接口中 MethodInterceptor

参数:

mi - 主要实现类:ReflectiveMethodInvocation

抛出:

Throwable

doProceed

protected Object doProceed(MethodInvocation mi)
                    throws Throwable

Proceed with the supplied MethodInterceptor. Subclasses can override this method to intercept method invocations on the target object which is useful when an introduction needs to monitor the object that it is introduced into. This method is never called for MethodInvocations on the introduced interfaces.

抛出:

Throwable
