SpringMVC 中文乱码解决办法

在web.xml或Spring默认的applicationContext.xml中配置过滤器。如下：

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<!-- 配置编码过滤器
-->

<filter>

<filter-name>Set Character Encoding</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><!-- 强制进行转码 -->

</init-param>

</filter>

<filter-mapping>

<filter-name>Set Character Encoding</filter-name>

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

</filter-mapping>

以上配置只对post方法有效，对于get方法，还需要在Tomcat的
conf/server.xml 文件中，找<Connector port="8080" />，在里面加uRIEncoding="UTF-8" 。如下：

<Connector port="8080" maxHttpHeaderSize="8192"

maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

enableLookups="false" redirectPort="8443" acceptCount="100"

connectionTimeout="20000" disableUploadTimeout="true" uRIEncoding="UTF-8"/>
