解放开发者之手！掌握ResponseUtil类，高效处理响应数据，让你的应用闪耀亮相

package com.zking.util;
import java.io.PrintWriter;
import javax.servlet.http.HttpServletResponse;
import com.fasterxml.jackson.databind.ObjectMapper;
public class ResponseUtil {
  public static void write(HttpServletResponse response,Object o)throws Exception{
    response.setContentType("text/html;charset=utf-8");
    PrintWriter out=response.getWriter();
    out.println(o.toString());
    out.flush();
    out.close();
  }
  public static void writeJson(HttpServletResponse response,Object o)throws Exception{
    ObjectMapper om = new ObjectMapper();
//    om.writeValueAsString(o)代表了json串
    write(response, om.writeValueAsString(o));
  }
}
