如何在 web.xml 中添加应用程序上下文

Question

如何将我的测试资源文件夹中的 applicationcontext.xml 添加到 web.xml。 我试过这个

<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> 

我运行mvn war:war 命令，并在apache 中部署war 文件。但它显示错误。

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

谁能帮帮我？谢谢

Answer 1

这是简单的 web xml 文件。参考它并根据您的需要更改路径。

<?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>

编辑： 此外，您的应用似乎缺少 spring-web jar。确保你在类路径中有它。

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

Answer 2

您的类路径中缺少spring-web.jar。

尝试在你的 maven 配置中添加这个：

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

您将 applicationContext.xml 放在测试目录中？这是一个巨大的错误。既然你使用mvn，你应该把它放在main->resource dir中，因为当你使用mvn war:war时，它不会在test dir中收集文件。然后放到web.xml下面

 <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>
