考虑在配置中定义类型为'org.springframework.security.authentication.AuthenticationManager'的bean

Question

我遵循了这里提到的一些建议，但它对我不起作用。因此，在这里提出问题

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

谁能指导我是什么问题以及如何解决这个问题？

错误：

APPLICATION FAILED TO START

Description:

Field authenticationManager in com.techprimers.security.springsecurityauthserver.config.AuthorizationServerConfig required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found.


Action:

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

authorization server config.Java

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

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

        security.tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }


    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients
                .inMemory()
                .withClient("ClientId")
                .secret("secret")
                .authorizedGrantTypes("authorization_code")
                .scopes("user_info")
                .autoApprove(true);
    }


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

        endpoints.authenticationManager(authenticationManager);
    }
}

resource server config.Java

@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);
    }
}

从https://github.com/TechPrimers/spring-security-oauth-mysql-example获取的代码引用，只更新了Spring Boot Parent Version到2.0.4.RELEASE，事情开始破坏。

这似乎是Spring Boot 2.0引入的“突破性变化”之一。我相信你的情况在Spring Boot 2.0 Migration Guide中有描述。

在你的WebSecurityConfigurerAdapter类中，你需要覆盖authenticationManagerBean方法并用@Bean注释它，即：

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

此外，在你的WebSecurityConfigurerAdapter而不是用AuthenticationManager注入@Autowired实例，你可以使用authenticationManagerBean()方法，即：

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