Question

我尝试使用Spring Security编写一个简单的Spring应用程序，但我遇到了错误。这是我收到的例外情况：

org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'org.springframework.security.filterChains': 
  Cannot resolve reference to bean 'org.springframework.security.web.DefaultSecurityFilterChain#0'
  while setting bean property 'sourceList' with key [0]; 
nested exception is org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'org.springframework.security.web.DefaultSecurityFilterChain#0': 
  Cannot resolve reference to bean 'org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter#0' 
  while setting constructor argument with key [5]; 
nested exception is org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter#0': 
  Cannot resolve reference to bean 'org.springframework.security.authentication.ProviderManager#0' 
  while setting bean property 'authenticationManager';
nested exception is org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'org.springframework.security.authentication.ProviderManager#0': 
  Cannot resolve reference to bean 'org.springframework.security.config.authentication.AuthenticationManagerFactoryBean#0' 
  while setting constructor argument; 
nested exception is org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'org.springframework.security.config.authentication.AuthenticationManagerFactoryBean#0': 
FactoryBean threw exception on object creation; 
nested exception is org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'org.springframework.security.authenticationManager': 
  Cannot resolve reference to bean 'org.springframework.security.authentication.dao.DaoAuthenticationProvider#0' 
  while setting constructor argument with key [0]; 
nested exception is org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'org.springframework.security.authentication.dao.DaoAuthenticationProvider#0': 
  Cannot resolve reference to bean 'UserDao' 
  while setting bean property 'userDetailsService'; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No bean named 'UserDao' is defined

我可以看到，bean UserDao存在问题是不可见的，尽管我有：<context:component-scan base-package="service, controller, dao" />。

我配置的其余部分：

我做错了所以请帮助我。谢谢！

Answer 1

我认为你的问题是什么：

{{1}}

我尝试在任何Spring项目中找到UserDao，但我在sample（sample.dao.UserDAO）中找到了。你真的知道UserDao类是任何Spring框架的一部分吗？据我所知，您需要自己创建身份验证提供程序类。
