本文主要是介绍配置应用程序监听器[org.springframework.web.context.ContextLoaderListener]错误，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
首先查看自己的配置文件(我maven项目)
web.xml(内容除了文件的配置位置外，是否有其他的不同)
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"version="4.0"><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:config/springmvc-config.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><!--让DispatcherServlet专注于.action--><url-pattern>*.action</url-pattern></servlet-mapping><!--编码过滤器--><filter><filter-name>encoding</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></filter><filter-mapping><filter-name>encoding</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- 配置加载spring文件的监听器 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:config/application.xml</param-value></context-param></web-app>第二部看applicationContext配置文件
<?xml version="1.0" encoding="UTF-8"?>

如果你这部分有路径的报错，直接将这个war删除，重新引入
之后就OK了。！！！（有别的问题私我，我一直在）
