java - 为身份验证管理器自动装配

问题描述

我想为 Oauth2 实现授权和资源服务器，这是我的参考站点，但是私有 AuthenticationManager authenticationManager 在 intellij 上给了我一个错误，例如“无法自动装配”，那么我该如何解决？

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;

@Configuration
@EnableAuthorizationServer
public class AuthorizationServer extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory().withClient("javainuse-client").secret("javainuse-secret")
                .authorizedGrantTypes("client_credentials").scopes("resource-server-read", "resource-server-write");
    }
}

解决方案

如果您必须使用 AuthenticationManager（并非总是如此，这取决于您管理用户的方式），则需要将其公开为 bean。像这样：

@Configuration
public static class AuthenticationMananagerProvider extends WebSecurityConfigurerAdapter {

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