本文详细记录了在启动Spring MVC项目时遇到的找不到/WEB-INF/applicationContext.xml配置文件的问题，通过调整web.xml中contextConfigLocation参数的值，成功解决了部署错误。文章提供了完整的web.xml和spring-mvc.xml配置，以及子工程的pom.xml示例。

鉴于昨天启动报错，今天来鼓捣鼓捣它；

错误呢

一直在找这个文件，/WEB-INF/applicationContext.xml

首先我在付工程内注掉了所有依赖工程，仅留下web项目

但是我整个项目中不存在这个文件，全文搜索后也没有发现有引用它的地方

web.xml的配置

<!-- Spring MVC servlet -->
    <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*:spring-mvc.xml</param-value>-->
            <param-value>classpath*:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
        <async-supported>true</async-supported>
    </servlet>

    <!-- Spring监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- 防止Spring内存溢出监听器 -->
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>


    <!-- 配置log4j配置文件路径 -->
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
    </context-param>
    <!-- 60s 检测日志配置 文件变化 动态加载log配置文件-->
    <context-param>
        <param-name>log4jRefreshInterval</param-name>
        <param-value>60000</param-value>
    </context-param>
    <!-- 配置Log4j监听器 -->
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

也没有发现太大的问题加在顺序也没事 排查后发现更换了默认位置读取配置

所以在最上面的位置增加了

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mvc.xml</param-value>
</context-param>

下面这段是引用的具体地址忘了，网上全是这个详解

该元素用来声明应用范围(整个WEB项目)内的上下文初始化参数。
param-name 设定上下文的参数名称。必须是唯一名称
param-value 设定的参数名称的值
在启动Web项目时，容器(比如Tomcat)会读web.xml配置文件中的两个节点<listener>和<contex-param>。
接着容器会创建一个ServletContext(上下文),应用范围内即整个WEB项目都能使用这个上下文。
接着容器会将读取到<context-param>转化为键值对,并交给ServletContext。
容器创建<listener></listener>中的类实例,即创建监听（备注：listener定义的类可以是自定义的类但必须需要继承ServletContextListener）。
在监听的类中会有一个contextInitialized(ServletContextEvent event)初始化方法，在这个方法中可以通过event.getServletContext().getInitParameter("contextConfigLocation")来得到context-param设定的值。在这个类中还必须有一个contextDestroyed(ServletContextEvent event)销毁方法.用于关闭应用前释放资源，比如说数据库连接的关闭。
得到这个context-param的值之后,你就可以做一些操作了.注意,这个时候你的WEB项目还没有完全启动完成.这个动作会比所有的Servlet都要早。
由上面的初始化过程可知容器对于web.xml的加载过程是context-param >> listener >> fileter >> servlet**

添加这段代码变更初始位置

 我把整个web项目的配置文件贴一下
