public class DelegatingIntroductionInterceptor extends IntroductionInfoSupport implements IntroductionInterceptor
Convenient implementation of theIntroductionInterceptorinterface.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
suppressInterfacemethod 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.

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
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- the method invocation joinpoint- 返回:
- the result of the call to
Joinpoint.proceed(); might be intercepted by the interceptor - 抛出:
Throwable- if the interceptors or the target object throws an exception
doProceed
protected Object doProceed(MethodInvocation mi) throws Throwable
Proceed with the suppliedMethodInterceptor. 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 forMethodInvocationson the introduced interfaces.- 抛出:
Throwable
