Question

我想将struts2与spring集成。所以我在web-inf / classes文件夹中使用了以下代码。

的applicationContext.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
    <beans>
     <bean id="helloWorldClass" class="com.test.spring.HelloWorld" >
          <property name="message" value="Hello World!" />
     </bean>
     </beans>

struts.xml中

    <!DOCTYPE struts PUBLIC 
         "-//Apache Software Foundation//DTD Struts Configuration  2.0//EN"
         "http://struts.apache.org/dtds/struts-2.0.dtd">
    <struts>    
    <struts-config>
    <!-- Spring Struts plugin -->
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
    <set-property property="contextConfigLocation"
        value="/WEB-INF/classes/applicationContext.xml" />
</plug-in>
    </struts-config>
    <constant name="struts.devMode" value="false" />
    <constant name="struts.objectFactory" value="spring" />
    <package name="default" extends="struts-default">
    <action name="helloWorld" class="helloWorldClass">
        <result name="SUCCESS">/success.jsp</result>
    </action>
    </package>
    </struts>

我已经使用这些文件和一个helloWorld类作为com.test.spring包。类中只包含变量消息的getter / setter方法。

pom.xml文件中的内容：

通过使用此文件，我已在目标中的web-inf / lib文件夹中下载了jar文件。

当我在glassfish服务器上传此war文件时，它显示以下错误消息。

部署期间发生错误：加载应用程序时出现异常：java.lang.IllegalStateException：ContainerBase.addChild：start：org.apache.catalina.LifecycleException：java.lang.NoClassDefFoundError：无法初始化类org.springframework .web.context.ContextLoader。有关详细信息，请参阅server.log。

任何人都可以帮我解决这个错误以及如何将struts2与spring集成。

先谢谢。

Answer 1

ContextLoaderPlugin与Struts 1一起使用。从struts.xml中的DOCTYPE开始，你使用的是Struts 2.

见这里：

http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/web-integration.html#struts

对于Struts 2，您应该使用Struts2-Spring插件。

如何解决无法初始化类org.springframework.web.context.ContextLoader？
