利用struts2的验证框架

package com.test.interceptor;

import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.Interceptor;

public class MyInterceptor implements Interceptor {
	
	public String hello;
	public void setHello(String hello) {
		this.hello = hello;
	}

	public void destroy() {
		System.out.println("destroy()...");
	}

	public void init() {
		System.out.println("init()...");
		System.out.println(hello);
	}

	public String intercept(ActionInvocation invocation) throws Exception {
		
		System.out.println("intercept()...");
		
		String result = invocation.invoke();
		
		return result;
