spring security 添加SwitchUser配置

进行了一段时间的修改终于更正了程序,我的开发环境是tomcat6 配置SwitchUser时如下配置文件

   
       
       
       
   

   
       
           
           
       

   

            class="org.springframework.security.ui.switchuser.SwitchUserProcessingFilter" autowire="byType">
   
            ref="org.springframework.security.userdetails.memory.InMemoryDaoImpl" />
   

但是这样配置的后果是

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name '_filterChainProxy': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '_filterChainList': Cannot create inner bean '(inner bean)' of type [org.springframework.security.config.OrderedFilterBeanDefinitionDecorator$OrderedFilterDecorator] while setting bean property 'filters' with key [11]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#2': Cannot resolve reference to bean 'switchUserProcessingFilter' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'switchUserProcessingFilter' defined in file [C:/Program Files/Apache Software Foundation/Tomcat 6.0/webapps/test1/WEB-INF/classes/applicationContext-security.xml]: Cannot resolve reference to bean 'org.springframework.security.userdetails.memory.InMemoryDaoImpl' while setting bean property 'userDetailsService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'org.springframework.security.userdetails.memory.InMemoryDaoImpl' is defined

原因InMemoryDaoImpl'是做为userDetailService接口的实现在使用时需要用户名 密码 用户是否有效和权限作为构造属性,其实

 
       
           
           
       

   

就已经把用户相关信息加载到内存了,我们只需要做的就是告诉tomcat如何去寻找这些信息,只需加入autowire="byType"属性即可。

具体的配置如下

  
       
       
       
   

   
       
           
           
       

   

   
             
      
  

   

重启tomcat即可。
