接口类:
public interface Service {
public void print();
}
实现类
package com.tao.proxy;
public class ServiceImpl implements Service {
@Override
public void print() {
System.out.println("hello");
}
}
代理类
public class TaoInvoker implements InvocationHandler {
private Object object ;
public TaoInvoker() {
}
public TaoInvoker(Object object) {
this.object = object;
}
public Object newProxy(Object target){
this.object = target;
return Proxy.newProxyInstance(target.getClass().getClassLoader(),target.getClass().getInterfaces(),this);
}
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
System.out.println("加强代码");
return method.invoke(object, args);
}
public static void main(String[] args) {
Service service = new ServiceImpl();
Service o = (Service) new TaoInvoker().newProxy(new ServiceImpl());
o.print();
}
}
加强代码
hello
