Question

我正在将我的EAR / WAR文件部署到Jboss 4.2，并且我已连接web.xml以加载公共应用程序上下文文件，因此我可以通过父弹簧上下文共享公共bean。

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"    
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-app_2_4.xsd"    
version="2.4">
<display-name>Validation Service</display-name>
<description>Validation Service</description>

<context-param>
    <param-name>locatorFactorySelector</param-name>
    <param-value>classpath*:coreBeanContext.xml</param-value>
</context-param>
<context-param>
    <param-name>parentContextKey</param-name>
    <param-value>coreBeanFactory</param-value>
</context-param>

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

我的'coreBeanFactory'被定义为使用'ClassPathXmlApplicationContext'。

<?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-2.0.xsd"
   default-lazy-init="true">

<bean id="coreBeanFactory"
    class="org.springframework.context.support.ClassPathXmlApplicationContext">
    <constructor-arg>
        <value>coreApplicationContext.xml</value>
    </constructor-arg>
</bean>

但是在启动期间，加载了coreBeanContext.xml文件，但是我得到了这个异常

Caused by: org.springframework.beans.factory.access.BootstrapException: 
Unable to return specified BeanFactory instance: factory key [coreBeanFactory], 
from group with resource name [classpath*:coreBeanContext.xml]; 
nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: 
Bean named 'coreBeanFactory' must be of type 
[org.springframework.beans.factory.BeanFactory],
but was actually of type 
[org.springframework.context.support.ClassPathXmlApplicationContext] 
at org.springframework.beans.factory.access.SingletonBeanFactoryLocator.useBeanFactory(SingletonBeanFactoryLocator.java:410)

我想知道为什么SingletonBeanFactoryLocator将这个bean选为错误的类型？

更新（2009年6月20日）

添加完整堆栈跟踪。我的应用程序使用@Webservice注释，在部署期间生成WSDL文件。接口中的一个对象引用需要在其构造函数中连接到数据库 - 以及查找导致此问题的spring数据源bean引用。 ATM - 我正在考虑使用SpringBeanAutowiringInterceptor来确保正确地注入对象。

Answer 1

我的猜测是Spring被两个不同的类加载器加载。如果是这种情况，则webapp的类加载器无法将父上下文强制转换为BeanFactory。

您的WAR已打包在您的EAR中，这是正确的吗？如果是这样，你是否在EAR中有一个Spring副本，或者你在WAR中有其他Spring JAR？

Answer 2

我会将此归类为弹簧配置的问题，而不是JBoss的类加载。你能描述一下这套配置的用途吗？

您是否只需要加载多个应用程序上下文，还是需要以这种方式加载应用程序上下文？

您可以尝试加载单个应用程序上下文并导入该配置中的所有其他应用程序上下文，或通过web.xml配置所有上下文并让它们加载spring context loader listener。

单个应用程序上下文：自动加载上下文${servlet-name}-servlet.xml。您可以按照Composing XML-based configuration metadata

<import/>

web.xml

：按照Common configuration中的说明配置Web应用程序的contextConfigLocation上下文参数。

如果您有任何特殊要求选择以这种方式配置应用程序，请提供更多详细信息。建议的方法是在外部配置所有上下文（在本例中通过web.xml上下文参数），或让上下文通过<import/>导入其他上下文。

我希望这可以提供帮助，
