SpringMVC jsp页面乱码

jsp页面中文输入，到controller乱码，这时候需要设置的是在web.xml文件中添加一个编码的过滤器（filter）将编码统一为UTF-8，代码如下:

<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>
