SSH jackson

MyEclipse2013自带的Struts2.1 + Spring 3.0.5 +Hibernate 3.3.2

结果拽里个jackson1.9.11-all的包，报错，于是把Spring下面的org.codehaus.jackson.mapper包干掉了。

然后把Struts的Action的配置里的result type改成了plainText，再也没有异常和错误了。

package com.lgh.common.tools.json;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.http.HttpServletResponse;

import org.codehaus.jackson.map.ObjectMapper;


public class JsonUtil {
	 public static void outToJson(HttpServletResponse response, Object data) 
		        throws IOException {
		        ObjectMapper mapper = new ObjectMapper();
		        response.setContentType("text/json; charset=utf-8");
		        response.setHeader("Cache-Control", "no-cache"); //取消浏览器缓存
		        PrintWriter out = response.getWriter();
		        
		        
		         String s = "";
		         s =  mapper.writeValueAsString(data);
		         
		         
		        out.print(s);
		        out.flush();
		        out.close();
		    }

}

package com.lgh.test;

import java.util.List;

import org.apache.struts2.ServletActionContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
