JavaWeb项目乱码问题解决方法

JavaWeb项目中遇到乱码问题基本是编码不统一导致

解决方式如下

1.web.xml添加filter方式解决

<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>

2.修改tomcat中server.xml中的编码

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

3.统一页面编码规则

A. JSP/Servlet都有的编码设置  request.setCharacterEncoding("UTF-8")  response.setCharacterEncoding("UTF-8")  response.setContentType("text/html; charset=UTF-8");  response.setHeader("Content-Type", "text/html; charset=UTF-8"); B. JSP专有的编码设置 1. <%@ page pageEncoding="UTF-8" %> 2. <%@ page contentType="text/html; charset=UTF-8" %> C. HTML页面中的编码设置 1. <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

其次针对开发环境也要设置好编码，我用的eclipse，设置方式  Window ->Preference ->General -> Workspace设置一下文件编码方式为UTF-8
