1. web.xml中配置了CharacterEncodingFilter,配置这个是拦截所有的资源并设置好编号格式。
encoding设置成utf-8就相当于request.setCharacterEncoding("UTF-8");
foreEncoding设置成true就相当于response.setCharacterEncoding("UTF-8");
<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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
2. web.xml配置DispatcherServlet，配置这个是拦截所有请求，都交给springmvc转发
拦截所有的请求，并加载所有的ssm配置文件（路径为classpath:---）
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-*.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
