springmvc 中遇到的乱码问题解决方式

最近在项目开发中遇到乱码问题，搞了很久终于解决，现在记录下来，以便以后用到。

最关键的只有3点

1.jsp

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

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

2.web.xml (这就是我项目中出问题的地方)

<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>false</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>

3.apache-tomcat-7.0.55\conf\server.xml

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