解决SpringMVC的中文乱码问题

Get请求乱码

在eclipse中找到Tomcat目录下的server.xml然后打开找到这一行添加一个URLEncoding=“utf-8” 就可以了

    <Connector URLEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

Post请求乱码

1、springMVC开发中遇到中文乱码问题
2、一定要post方式，get方式会乱码

<form action="${ctx}/user/addUser" name="userForm" method="post"> 

3、修改web.xml，增加编码过滤器，如下（注意，需要设置forceEncoding参数值为true）

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
