1、解决post请求传递参数中文乱码。

在web.xml中添加如下配置
<filter>
<filter-name>CharacterEncoding</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>CharacterEncoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
2、解决get传递参数时中文乱码
修改tomcatserver.xml中的
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>这句，添加字符编码URIEncoding="UTF-8"如下：
<Connector connectionTimeout="20000" port="80" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>。
