Java 动态代理Proxy和Invacationhandler的使用

private DynamicMethod mDynamicMethod;
private Object mDelegate;

public QxInvocationHandler(Object delegate) {
this.mDelegate = delegate;
}

public QxInvocationHandler(Object delegate, DynamicMethod dynamicMethod) {
this.mDelegate = delegate;
this.mDynamicMethod = dynamicMethod;
}

public Object bind() {
return Proxy.newProxyInstance(Thread.currentThread().getContextClassLoader(),
mDelegate.getClass().getInterfaces(), this);
}

@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
Object obj = null;
if (mDynamicMethod != null) {
mDynamicMethod.beforeInvokeMothed();
}
obj = method.invoke(mDelegate, args);
if (mDynamicMethod != null) {
mDynamicMethod.afterInvokeMehod();
}
return obj;
}

public void setmDynamicMethod(DynamicMethod mDynamicMethod) {
this.mDynamicMethod = mDynamicMethod;
}

public interface DynamicMethod {
void beforeInvokeMothed();

void afterInvokeMehod();
}
