## 场景描述 ##

项目为idea自动创建的 maven工程，使用webapp archetype自动生成的web.xml

在整合spring和springMVC的时候需要在web.xml中添加spring的容器配置

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/applicationContext-*.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

添加前没有异常，添加后web-app标签红线异常。

--------------------

## 异常原因 ##

文档内容标签顺序不符合web-app\_2\_3.dtd规范

--------------------

## 解决方案 ##

方案一：严格按照提示上的顺序排列  
方案二：删除

--------------------
