出错提示:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.security.authentication.AuthenticationManager] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

注入申明:

@Autowired

privateAuthenticationManager authenticationManager;

解决方案:

在WebSecurityConfigurerAdapter的实现类当中，重写authenticationManagerBean方法：

@Bean(name = BeanIds.AUTHENTICATION_MANAGER)

@Override

publicAuthenticationManagerauthenticationManagerBean() throws Exception {

    return super.authenticationManagerBean();   

}
