java调用cxf webservice时，启动Tomcat报错。。

org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'cxf': Singleton bean creation not allowed while the singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

请大侠看看什么原因导致。。？
哦 晓得是啥问题了。。
在创建cxf webservice的时候，在web.xml中少配了个beans.xml，导致bean.xml没有读取
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring/applicationContext*.xml,classpath*:beans.xml</param-value>
</context-param>

Answer 1

只会存在一个共享的bean实例，并且所有对bean的请求，只要id与该bean定义相匹配，则只会返回bean的同一实例。换言之，当把一个bean定义设置为singleton作用域时，Spring IOC容器只会创建该bean定义的唯一实例。这个单一实例会被存储到单例缓存（singleton cache）中，并且所有针对该bean的后续请求和引用都将返回被缓存的对象实例，这里要注意的是singleton作用域和GOF设计模式中的单例是完全不同的，单例设计模式表示一个ClassLoader中只有一个class存在，而这里的singleton则表示一个容器对应一个bean，也就是说当一个bean被标识为singleton时候，spring的IOC容器中只会存在一个该bean。

配置实例：

<bean id="role" class="spring.chapter2.maryGame.Role" scope="singleton"/>

或者

<bean id="role" class="spring.chapter2.maryGame.Role" singleton="true"/>

看看你的这个BEAN的定义，是不是正常。建议把配置文件贴出来

Answer 2

把配置文件贴出来吧，这样很难排的

Answer 3

同意楼，楼上的。 估计你的配置文件里的bean有问题。
