struts2返回值问题（需要返回自定义值）

struts2返回自定义的值除了去掉get方法，还可以通过自定义一个返回方法，就像servlet一样返回值。

这里需要注意的是action方法中不需要return SUCCESS。

package com.hyit.ttmsoge.action;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.LinkedList;
import java.util.List;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;

import sun.org.mozilla.javascript.internal.EcmaError;

import com.hyit.ttmsoge.model.JobNews;
import com.hyit.ttmsoge.service.JobNewsService;
import com.opensymphony.xwork2.ActionSupport;

public class JobNewsAction extends ActionSupport {
	private static final long serialVersionUID = 1L;
	private String start;
	private String limit;
	private int totalProperty;
	
	public void setTotalProperty(int totalProperty) {
		this.totalProperty = totalProperty;
	}
	public void setStart(String start) {
		this.start = start;
	}
	public void setLimit(String limit) {
		this.limit = limit;
	}
	private JobNewsService jobNewsService;
	public void setJobNewsService(JobNewsService jobNewsService) {
		this.jobNewsService = jobNewsService;
	}
	public void getJobNews() throws Exception{
		ArrayList<JobNews> jobNewsList=this.jobNewsService.loadJobNews();
		if(jobNewsList!=null&&jobNewsList.size()!=0){
			this.setTotalProperty(jobNewsList.size());
			String returnValue="{totalProperty:"+totalProperty+",root:[";
			int index=Integer.parseInt(start);
			int pageSize=Integer.parseInt(limit);
		System.out.println("start:"+start+"....limit:"+limit);
			if(pageSize==0){
				pageSize=10;
			}
			for(int i = index;i < pageSize+index&&i<jobNewsList.size(); i ++){
				JobNews jobNews=jobNewsList.get(i);
				//list.add(jobNews);
				returnValue+="{id:"+jobNews.getId()+",newsName:'"+jobNews.getNewsName()+"',createTime:'"+jobNews.getCreateTime()+"'}";
				if(i!=pageSize+index-1){
					returnValue+=",";
				}
			}
			returnValue+="]}";
			this.sendMsg(returnValue);
		
		}
	}
	
	 public void sendMsg(String content) throws IOException{      
	        HttpServletResponse response = ServletActionContext.getResponse();      
	        response.setCharacterEncoding("UTF-8");      
	        response.getWriter().write(content);      
	   }
}
