1.中文乱码解决方案，确保每个文件的默认编码是UTF-8

 

 

 

 

 

 

 

 

 

 

 

 

 

加入 URIEncoding="UTF-8"

代码中的设置

1>在servlet中加入

//1.设置response的编码为utf-8

response.setCharacterEncoding("utf-8");

//2.通知浏览器，以UTF-8的编码打开

response.setContentType("text/html;charset=UTF-8");

2>在应用的地方加入

new String(userName.getBytes("ISO-8859-1"), "gb2312")

3>在JSP文件中加入

<%@ page language="java" import="java.util.*" contentType="text/html; charset=GB2312" %>

4>在web.xml中加入过滤器

<!-- 配置中文乱码过滤 -->

<filter>

<filter-name>encodingFilter</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>UTF-8</param-value>

</init-param>

<init-param>

<param-name>forceEncoding</param-name>

<param-value>true</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>encodingFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>
