Question

请在运行我的应用程序时为什么会出现此错误

SEVERE: StandardWrapper.Throwable
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityServiceImpl': Injection of autowired dependencies failed;
 nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.security.authentication.AuthenticationManager com.springfoundation.service.SecurityServiceImpl.authenticationManager; 
 nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
  No unique bean of type [org.springframework.security.authentication.AuthenticationManager] is defined:
  expected single matching bean but found 3: 
  [org.springframework.security.config.authentication.AuthenticationManagerFactoryBean#0,

   org.springframework.security.authenticationManager]

这是第二个堆栈跟踪

Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.security.authentication.AuthenticationManager com.springfoundation.service.SecurityServiceImpl.authenticationManager; 
 nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:

有什么问题？

Answer 1

<bean id="object name" class="com.java.model.FirstModelImple" />

org.springframework.beans.factory.BeanCreationException：创建名为＆＃39; securityServiceImpl＆＃39;的bean时出错：
