在tomcat中启动应用程序时出错

Question

当我试图从web.xml映射ApplicationContext.xml文件以使用spring ioc时，我的应用程序没有开始在catalina.out中显示以下错误

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
  /WEB-INF/applicationContext.xml
  </param-value>
</context-param>

Answer 1

应用程序上下文是由web.xml中定义的ContextLoaderListener或ContextLoaderServlet初始化的容器，配置如下所示：

 <listener>
         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <context-param>
         <param-name>contextConfigLocation</param-name>
        <param-value> /WEB-INF/applicationContext.xml  </param-value>
    </context-param>

和servlet标记

<servlet>
   <servlet-name>myservlet</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>app-servlet.xml</param-value>
   </init-param>
</servlet>
