本文探讨了Spring与Struts联合使用时配置冲突的问题。由于web.xml与struts-config.xml中重复配置了contextConfigLocation参数，导致应用上下文中的bean被重复加载。通过移除web.xml中的重复配置解决了该问题。

spring+structs配置不当导致无法正常获取bean

异常如下：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'userProfileMananger' is definedorg.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:360)org.springframework.beans.factory.support.AbstractBeanFactory.getMergedBeanDefinition(AbstractBeanFactory.java:692)org.springframework.beans.factory.support.Abstra

web.xml文件配置如下

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/applicationContext-*.xml</param-value>

</context-param>

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

</listener>

<servlet-name>action</servlet-name>

<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>

<init-param>

<param-name>config</param-name>

<param-value>/WEB-INF/struts-config.xml</param-value>

</init-param>

<init-param>

<param-name>debug</param-name>

<param-value>3</param-value>

</init-param>

<init-param>

<param-name>detail</param-name>

<param-value>3</param-value>

</init-param>

<load-on-startup>0</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>action</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

structs-config.xml配置如下

<struts-config>

<data-sources />

<form-beans />

<global-exceptions />

<global-forwards />

<action-mappings >

</action>

</action-mappings>

<message-resources parameter="com.homecounter.web.ApplicationResources" />

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn" >

<set-property property="contextConfigLocation" value="/WEB-INF/applicationContext-*.xml"/>

</plug-in>

</struts-config>

调用

WebApplicationContext wac = this.getWebApplicationContext();

UserProfileManager profileMan = (UserProfileManager)wac.getBean("userProfileMananger");

使用如上方法获取bean userProfileMananger 时，出现文章开头的异常；但是使用如下代码

BeanFactory factory = new XmlBeanFactory(new FileSystemResource("E://workspace//HomeCounter//WebRoot//WEB-INF//applicationContext.xml"));

UserProfileManager profileMan = (UserProfileManager)wac.getBean("userProfileMananger");

获取bean 时，没有任何异常；
