本文介绍了一个BaseController类，该类包含两个方法：printJSON用于将对象转化为JSON并输出，print用于输出非JSON化的对象内容。这两个方法都确保了请求和响应的字符编码为UTF-8。

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();
}
}
