如何在web.xml中添加應用程序上下文

Question

如何將位於我的測試資源文件夾中的applicationcontext.xml添加到web.xml中。 我想這

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/test/resources/com/reg/applicationcontext.xml</param-value> 
</context-param> 

<listener> 
    <listener-class> 
     org.springframework.web.context.ContextLoaderListener 
    </listener-class> 
</listener> 

我運行mvn war:war命令，我在部署阿帕奇戰爭文件。但它顯示錯誤。

Mar 12, 2013 11:31:07 AM org.apache.catalina.core.StandardContext startInternal 
SEVERE: Error listenerStart 
Mar 12, 2013 11:31:07 AM org.apache.catalina.core.StandardContext startInternal 
SEVERE: Context [/myapp] startup failed due to previous errors 

任何人都可以幫我嗎？謝謝

localhost。

Answer 1

您在類路徑中缺少spring-web.jar。

試着在你的Maven配置補充一點：

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-web</artifactId> 
    <type>jar</type> 
    <scope>compile</scope> 
</dependency> 

Answer 2

您將applicationContext.xml放在測試目錄中？這是一個巨大的錯誤。既然你使用mvn，你應該把它放在main-> resource dir中，因爲當你使用mvn war:war時，它不會收集測試目錄中的文件。然後放在web.xml中

<context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value> 
      classpath:**the sub dir in you resource which the config xml is in** /applicationContext.xml 
     </param-value> 
    </context-param> 

Answer 3

這是簡單的web xml文件。根據您的需要參考&更改路徑。

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="2.5" 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_2_5.xsd"> 

<!-- The definition of the Root Spring Container shared by all Servlets and Filters --> 
<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/spring/root-context.xml</param-value> 
</context-param> 

<!-- Creates the Spring Container shared by all Servlets and Filters --> 
<listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
</listener> 

<!-- Processes application requests --> 
<servlet> 
    <servlet-name>appServlet</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 

<servlet-mapping> 
    <servlet-name>appServlet</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping> 

編輯： 此外，您的應用程序似乎缺少彈簧網絡罐子。確保你在classpath中有它。

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-web</artifactId> 
    <version>${your_spring_vserion}</version> 
</dependency>
