mysql中jsp中文乱码怎么解决

JSP页面传输到MySQL数据库时，中文为乱码（数据库中存储乱码）解决方法：

将所有的涉及到编码的都设置为utf-8即可。

执行mysql> show variables like 'character%';命令查看mysql使用的编码方式：

mysql> show variables like 'character%';

| character_set_connection | utf8 |

| character_set_database | utf8 |

修改数据库编码执行命令： mysql> alter database db_name character set utf8;

修改其他编码： mysql> set names 'utf8';

设置JSP页面编码：在页面顶部添加：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

修改数据库连接DriverManager.getConnection(url, usr, pwd)的url：

String url = "jdbc:mysql://localhost:3306/db_name?useUnicode=true&characterEncoding=utf-8";

在发送页面和接收页面顶部都添加以下代码：

<%  request.setCharacterEncoding("UTF-8"); 
    response.setCharacterEncoding("UTF-8"); 
    response.setContentType("text/html; charset=utf-8");
%>
