解决中文乱码，在web.xml中配置核心过滤器
方法一、手动编写中文乱码过滤器
<!-- 配置核心过滤器 --> <filter> <filter-name>SetCharacterEncoding</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>SetCharacterEncoding</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> <dispatcher>INCLUDE</dispatcher> </filter-mapping> <filter-mapping> <filter-name>SetCharacterEncoding</filter-name> <url-pattern>*.jsp</url-pattern> </filter-mapping>
