  • Dao层访问数据库时指定编码格式
    

  Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/micro_message?characterEncoding=utf8","root","root");

  • Servlet中要设置request域的编码格式（req为 HttpServletRequest参数）

  req.setCharacterEncoding("UTF-8");

  • jsp中格式设置

  <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"  contentType="text/html; charset=utf-8"%>
