写一个BaseController来提取出json化输出数据和非json化输出数据

package com.controller;


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


import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


import com.alibaba.fastjson.JSON;


public class BaseController {
// 输出JSON化的content
public void printJSON(Object content, HttpServletRequest req,
HttpServletResponse rsp) throws IOException {
req.setCharacterEncoding("utf-8");
rsp.setCharacterEncoding("utf-8");
PrintWriter out = rsp.getWriter();
out.print(JSON.toJSONString(content));
out.flush();
out.close();
}


// 输出非JSON化的content
public void print(Object content, HttpServletRequest req,
HttpServletResponse rsp) throws IOException {
req.setCharacterEncoding("utf-8");
rsp.setCharacterEncoding("utf-8");
PrintWriter out = rsp.getWriter();
out.print(content.toString().trim());
out.flush();
out.close();
}
}
