接口 MethodInterceptor

函数接口:

这是一个函数接口, 因此可用作 lambda 表达式或方法引用的赋值目标。

@FunctionalInterface
public interface MethodInterceptor

Intercepts calls on an interface on its way to the target. These are nested "on top" of the target.

The user should implement the invoke(MethodInvocation) method to modify the original behavior. E.g. the following class implements a tracing interceptor (traces all the calls on the intercepted method(s)):

 class TracingInterceptor implements MethodInterceptor {
        Object invoke(MethodInvocation i) throws Throwable {
                System.out.println("method " + i.getMethod() + " is called on "
                                + i.getThis() + " with args " + i.getArguments());
                Object ret = i.proceed();
                System.out.println("method " + i.getMethod() + " returns " + ret);
                return ret;
    }
 }
