项目的目录结构如下

首先，配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <display-name>SSM</display-name>
  
  <!-- session和cookie的配置 -->
  <session-config>
    <session-timeout>40</session-timeout>
    <cookie-config>
      <name>SSM</name>
      <http-only>true</http-only>
    </cookie-config>
  </session-config>
  
  <!-- 访问的首页的配置 -->
  <welcome-file-list>
    <welcome-file>index.htm</welcome-file>
  </welcome-file-list>
  
  <!-- springMVC的拦截器配置，这个是重点 -->
  <servlet>
    <servlet-name>spring-dispatcher</servlet-name>

  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <!-- 防止乱码的配置，这个配置的mapping一定要在loginFilter之前，否则loginFilte里乱码 -->
  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>

  </filter>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <servlet-name>spring-dispatcher</servlet-name>
  </filter-mapping>
  
  <!-- 自定义的登录过滤器 -->
  <filter>
    <display-name>LoginFilter</display-name>
    <filter-name>LoginFilter</filter-name>
    <filter-class>com.lx.filter.LoginFilter</filter-class>
    <init-param>
      <param-name>indexPath</param-name>
      <param-value>index.htm</param-value>
    </init-param>
    <init-param>

      <param-value></param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>LoginFilter</filter-name>
    <url-pattern>*.htm</url-pattern>
  </filter-mapping>
  
  <!-- 错误页面，平常多用静态页面，这里用了动态页面，目的是为了对异常进行动态的处理 -->
  <error-page>
    <error-code>500</error-code>
    <location>/testError.htm</location>
  </error-page>
  <error-page>
    <exception-type>java.lang.Throwable</exception-type>

  <!-- 测试用的Servlet -->
  <servlet>

  <!-- 测试用的监听器 -->
  <listener>
    <listener-class>com.lx.listeners.TestListenser</listener-class>
  </listener>
</web-app>
