提问by Jeff Cook

I followed few suggestions mentioned here, but it didn't work for me. Hence, putting the question here

我遵循了这里提到的一些建议，但它对我不起作用。因此，把问题放在这里

1. How To Inject AuthenticationManager using Java Configuration in a Custom Filter
2. Spring required a bean of type 'AuthenticationManager'

1. 如何在自定义过滤器中使用 Java 配置注入 AuthenticationManager
2. Spring 需要一个类型为“AuthenticationManager”的 bean

Could anyone please guide me what's the issue and how to fixed that ?

任何人都可以请指导我是什么问题以及如何解决这个问题？

Consider defining a bean of type 'org.springframework.security.authentication.AuthenticationManager' in your configuration.

AuthorizationServerConfig.java

授权服务器配置文件

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {

                .scopes("user_info")
                .autoApprove(true);
    }


    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {

        endpoints.authenticationManager(authenticationManager);
    }
}

ResourceServerConfig.java

资源服务器配置文件

@EnableResourceServer
@Configuration
public class ResourceServerConfig extends WebSecurityConfigurerAdapter {


    @Autowired
    @Qualifier("authenticationManagerBean")
    private AuthenticationManager authenticationManager;
    @Autowired
    private UserDetailsService customUserDetailsService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.requestMatchers()
                .antMatchers("/login", "/oauth/authorize")
                .and()
                .authorizeRequests()
                .anyRequest()
                .authenticated()
                .and()
                .formLogin()
                .permitAll();
    }


    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.parentAuthenticationManager(authenticationManager)
                .userDetailsService(customUserDetailsService);
    }
}

The code reference taken from https://github.com/TechPrimers/spring-security-oauth-mysql-example, only updated Spring Boot Parent Version to 2.0.4.RELEASE, things started breaking.

It seems like it's one of the "breaking changes" Spring Boot 2.0 introduced. I believe that your case is described in Spring Boot 2.0 Migration Guide.

这似乎是 Spring Boot 2.0 引入的“重大变化”之一。我相信您的情况在Spring Boot 2.0 Migration Guide 中有所描述。

In your WebSecurityConfigurerAdapterclass you need to override authenticationManagerBeanmethod and annotate it with @Bean, i.e.:

在您的WebSecurityConfigurerAdapter课程中，您需要覆盖authenticationManagerBean方法并用 注释它@Bean，即：

@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

Moreover, in your WebSecurityConfigurerAdapterinstead of injecting the AuthenticationManagerinstance with @Autowiredyou can just use the authenticationManagerBean()method, i.e.:

此外，在您WebSecurityConfigurerAdapter而不是注入AuthenticationManager实例时，@Autowired您可以使用该authenticationManagerBean()方法，即：

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception 
{
    auth.parentAuthenticationManager(authenticationManagerBean());
        .userDetailsService(customUserDetailsService);
}

回答by Hilal Aissani

just add this to the AuthenticationManagerBuilder

@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

and in your controller where you need to use it add this :

 @Autowired
    private AuthenticationManager authenticationManager;
