SpringMVC处理POST请求乱码问题

在springmvc.xml中添加以下过滤器:

<filter>        <filter-name>characterEncodingFilter</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>  </filter>  <filter-mapping>    <filter-name>characterEncodingFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>
