在 Spring 4.3.5 中，我们一直在使用一种应用程序架构，在该架构中我们一次性初始化一些 bean，然后将这些 bean 用作其他 bean 的“参考”。
像这样的东西
<bean id="handleUncheckedEndpointExceptionAdvice"
class="com.gehcit.cp.ws.infrastructure.aop.advices.HandleUncheckedEndpointExceptionAdvice">
<constructor-arg ref="exceptionFactory"/>
<property name="exceptionSenderService" ref="exceptionSenderService" />
</bean>
但是一旦我们将库升级到 Spring 5.2.x，我们开始在 Jboss 7.3.1 启动时遇到以下异常：
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'handleUncheckedEndpointExceptionAdvice' defined in ServletContext resource [/WEB-INF/context-web.xml]: Cannot resolve reference to bean 'exceptionSenderService' while setting bean property 'exceptionSenderService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'exceptionSenderService' available
我所做的一切：
启用 TRACE 日志记录并发现这一点 -2022-03-05 13:09:39,927 TRACE [org.springframework.beans.factory.annotation.InjectionMetadata] (ServerService Thread Pool -- 65) Processing injected element of bean 'exceptionSenderService': AutowiredFieldElement for private com.gehcit.cp.serviceability.service.ExceptionSenderService com.gehcit.cp.cem.aplix.jms.service.Impl.AplixPublisherQueueServiceImpl.exceptionSender 2022-03-05 13:09:39,927 TRACE [org.springframework.beans.factory.support.DefaultListableBeanFactory] (ServerService Thread Pool -- 65) Returning cached instance of singleton bean 'exceptionSenderServiceImpl' 2022-03-05 13:09:39,927 TRACE [org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor] (ServerService Thread Pool -- 65) Autowiring by type from bean name 'exceptionSenderService' to bean named 'exceptionSenderServiceImpl'
现在 bean 正在初始化，但是当搜索引用时，从 Spring 缓存中搜索，我们什么也得不到。
但是后来我们尝试将 bean 初始化从不同的 xml 转移到 bean 被引用的相同 xml 并且有效。所以我们得出结论，不知何故，跨 XML 配置不起作用。
从 context-web.xml 引用的 Bean

有人可以帮我找到一种方法来引用 Spring 5.2.x 中其他 xml 文件中的 bean。 注意：我们已经用 Spring 5.2 更改了类加载部分。
将此添加到 web.xml
<listener-class>com.gehcit.cp.ws.infrastructure.security.BeanFactoryContextLoaderListener</listener-class>
</listener>
<!-- <context-param>
<param-name>locatorFactorySelector</param-name>
<param-value>/beanRefFactory.xml</param-value>
</context-param> -->
BeanFactoryContextLoaderListener.java
package com.gehcit.cp.ws.infrastructure.security;
import javax.servlet.ServletContext;
import org.apache.log4j.Logger;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.web.context.ContextLoaderListener;
public class BeanFactoryContextLoaderListener extends ContextLoaderListener {
private static Logger log = Logger.getLogger(BeanFactoryContextLoaderListener.class)
@Override
protected ApplicationContext loadParentContext(ServletContext servletContext) {
log.info("Entered loadParentContext");
ApplicationContext ctx = new ClassPathXmlApplicationContext("beanRefFactory.xml");
log.info("Exit loadParentContext" + ctx.toString());
return ctx;
}
}
