ssm框架下web项目,web.xml配置文件的作用(详解)

时间:2021-11-05 22:59:43

1. web.xml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:---)
