ssm框架结构--web.xml的具体配置

1.创建maven工程.在pom.xml中添加必要的依赖

2.在web.xml中配置spring核心监听器

　　配置spring的xml配置文件路径

<context-param>
<param-name>contextConfigLocation</param-name>
  <param-value>classpath:applicationContext.xml</param-value>
 </context-param>
　　配置spring核心监听器

        <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>

　　配置后台接收的servlet
　　　

<!--springmvc后台配置-->
<servlet>
    <servlet-name>back</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:springmvc-back.xml</param-value>
    </init-param>
</servlet>
<servlet-mapping>
