配置应用程序监听器[org.springframework.web.context.ContextLoaderListener]错误

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"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-4.3.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">

    <import resource="spring-mapper.xml"></import>
    <import resource="spring-service.xml"></import>
    <import resource="springmvc-config.xml"></import>


</beans>

 spring-mapper文件

spring-service文件

    <!--扫描service包下-->

    <!--配置事务管理器-->

    <!--开启事务注解支持

    <!--    <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>-->
    <tx:annotation-driven></tx:annotation-driven>


</beans>

第三步（上面无误的话大概率是maven的问题）

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）
