春季升级期间的配置问题

Question

以下是我在春季升级期间遇到的问题。我觉得问题在于doctype.Please建议

   Bean 'cdqiPerformanceMonitor'; nested exception is
  org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
  Configuration problem: Old 1.x 'singleton' attribute in use - upgrade to
 'scope' declaration
  Offending resource: ServletContext resource [/WEB-
  INF/applicationContext.xml]

以下是应用程序上下文xml

  

    <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"     "http://www.springframework.org/dtd/spring-beans.dtd">    
<beans>    
   <bean id="cdqiPerformanceMonitor"        
   class="com.tms.cdqi.framework.aop.interceptor.CDQIPerformanceMonitorInterceptor"         />
<bean  id="cdqiApplicationContextFactory"class="com.tms.cdqi.framework.context.CDQIApplicationContextFactoryImpl" />  
<bean  id="commandInvoker"class="org.springframework.ejb.access.LocalStatelessSessionProxyFactoryBean"  
lazy-init="true">  
<property name="jndiName">  
<value>ejb/CommandInvokerLocal</value>  
</property>
<property name="businessInterface">
<value>  
com.tms.cdqi.application.command.invoker.CommandInvoker  
</value>  
</property>  
</bean>  
</beans>

下面是堆栈跟踪

    listener org.springframework.web.context.ContextLoaderListener
   failed:
   org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
 Configuration problem: Unexpected failure during bean definition parsing
  Offending resource: ServletContext resource [/WEB-
  INF/applicationContext.xml]
  Bean 'cdqiPerformanceMonitor'; nested exception is 
  org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
  Configuration problem: Old 1.x 'singleton' attribute in use - upgrade to
 'scope' declaration
 Offending resource: ServletContext resource [/WEB-
  INF/applicationContext.xml]

见SPR-12167。 Spring不再接受singleton="true"，因此您必须使用scope="singleton"。
