最近有几个小伙伴在开发的时候竟然还出现了乱码情况，检查了下，竟然没写filter-mapping，记录下
通过类org.springframework.web.filter.CharacterEncodingFilter，操作web.xml
<filter> <filter-name>Spring character encoding filter</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>Spring character encoding filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
