Spring ContextLoaderListener 忽略标签答案

【问题标题】：Spring ContextLoaderListener ignores tagSpring ContextLoaderListener 忽略标签
【发布时间】：2014-04-14 08:55:12
【问题描述】：

我不知道我是否遗漏了一些东西，我阅读了文档并询问了很多，但不知道为什么我的应用程序会这样。我的网络应用程序一直在抱怨 java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/applicationContext.xml] 在启动期间。

即使我的web.xml 文件包含此标签，也会发生这种情况

 <context-param>    
    <param-name>contextConfigLocation</param-name>                
    <param-value>some/nonexisting/path.xml</param-value>         
    </context-param>

这里完成web.xml

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
        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.xsd">

        <import resource="datasource-config.xml" />
        <import resource="webflow-config.xml" />        



</beans>

我在加载applicationContext.xml 文件时遇到问题，这可能是解决它的关键。为什么不管 contextLoaderListener 从默认路径加载 xml 文件？

【问题讨论】：

注意你有不同版本的spring，尽量保持相同的lvl。

标签： java xml eclipse spring

【解决方案1】：

尝试将其添加到web.xml检查您的声明顺序

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
     version="3.0">

<display-name>AppName</display-name>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext*.xml</param-value>
</context-param>
  //... 
 </web-app>

而不是你的<context-param> 标签

然后将您的 applicationContext.xml 放入 src->java->resources 应该会有所帮助。

确保您的WEB-INF 中的dispatcherServletContext.xml 与您拥有web.xml 的目录相同。

dispatcherServletContext.xml：

 <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:context="http://www.springframework.org/schema/context"
           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-4.0.xsd
            http://www.springframework.org/schema/context 
            http://www.springframework.org/schema/context/spring-context-4.0.xsd">

        <context:component-scan base-package="yourPackage"/>

        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix">
                <value>/WEB-INF/${pagesPath}</value>
            </property>
            <property name="suffix">
                <value>.jsp</value>
            </property>
        </bean>

    </beans>

【讨论】：

同样的结果Could not open ServletContext resource [/WEB-INF/applicationContext.xml]
你有没有dispatcherServletContex.xml? 再次查看我的答案。
不，我没有。我已经完成了您的建议，但在服务器上运行应用程序再次出现同样的错误。这是我的文件夹结构clip2net.com/s/7dBn7J
谢谢先生任何进一步的帮助将不胜感激
原来可能是 Eclipse 问题。我试图配置动态网页而不是 Maven 项目。我从简单的 spring hello world 开始。应用程序表现得像它应该的那样，但仍然在控制台中 tomcat 抱怨缺少appcontext.xml
