                </configuration>

            </plugin>
        </plugins>
    </build>

• 编写application.yml

server:
  port: 8090
  servlet:
    context-path: /auth   # 应用名 localhost:8090/auth

• com.mengxuegu.oauth2路径下编写启动类

@SpringBootApplication
public class AuthServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(AuthServerApplication.class, args);
    }
}

• 编写配置类

@Configuration
@EnableAuthorizationServer // 开启了认证服务器
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private PasswordEncoder passwordEncoder;
    /**
     * 配置被允许访问此认证服务器的客户端信息
     * 1.内存方式
     * 2. 数据库方式
     * @param clients
     * @throws Exception
     */
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        // 内存方式管理客户端信息
        clients.inMemory()
                .withClient("mengxuegu-pc") // 客户端id
                .secret(passwordEncoder.encode("mengxuegu-secret")) // 客户端密码，需加密
                .resourceIds("product-server") // 资源id，可理解为微服务名称，表示可访问哪些微服务
                .authorizedGrantTypes("authorization_code", "password", "implicit", "client_credentials", "refresh_token")  //认证模式
                .scopes("all") // 授权范围标识，哪部分资源可访问（all只是标识，不是说所有资源）
                .autoApprove(false) // false 跳到一个授权页面手动点击授权，true不需要手动点授权，直接响应一个授权码
                .redirectUris("http://www.mengxuegu.com/") // 客户端回调地址
            ;
    }
}

@Configuration
public class SpringSecurityBean {
    @Bean
    public PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }
}

@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private PasswordEncoder passwordEncoder;
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("admin").password(passwordEncoder.encode("1234"))
                .authorities("product");
    }
}

• 测试

# 浏览器访问
http://localhost:8090/auth/oauth/authorize?client_id=mengxuegu-pc&response_type=code
# 进入用户认证页面，输入用户名和密码
# 选择将哪些资源开放给第三方客户端（之前在配置类中配置了autoApprove(false)表示手动选择要开放的资源）

• 获取授权码

http://localhost:8090/auth/oauth/authorize?client_id=mengxuegu-pc&response_type=code

• 密码模式

# SpringSecurityConfig类中添加如下
    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

# AuthorizationServerConfig类中添加如下
    @Autowired // SpringSecurityConfig添加到容器中了
    private AuthenticationManager authenticationManager;
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        // 密码模式要设置认证管理器
        endpoints.authenticationManager(authenticationManager);
    }

• postman测试
  
  

• 简单模式

# 浏览器访问
http://localhost:8090/auth/oauth/authorize?client_id=mengxuegu-pc&response_type=token

• 客户端模式
  

• 使用redis管理访问令牌

# 添加依赖
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

# 编写TokenConfig
@Configuration
public class TokenConfig {
    @Autowired   //采用redis管理token
    private RedisConnectionFactory redisConnectionFactory;
    @Bean
    public TokenStore tokenStore() {
        // redis 管理令牌
        return new RedisTokenStore(redisConnectionFactory);
    }
}

# AuthorizationServerConfig配置如下
    @Autowired // token管理方式，在TokenConfig类中已对添加到容器中了
    private TokenStore tokenStore;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        // 令牌的管理方式
        endpoints.tokenStore(tokenStore);
    }

• 本地启动redis测试
• 由于我本地没有安装redis

# yml中配置如下
spring:
  redis:
    database: 0
    host: 124.222.5.107
    port: 6379
    password: 123456
#    client-type: lettuce
#    lettuce:
#      pool:
#        max-active: 8
#        max-wait: -1ms
#        max-idle: 8
#        min-idle: 0
    timeout: 2000

• 启动报错

Unable to connect to Redis; nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to 124.222.5.107:6379

# 编写TokenConfig

    private RedisConnectionFactory redisConnectionFactory;
    @Bean
    public TokenStore tokenStore() {
        // redis 管理令牌
        return new RedisTokenStore(redisConnectionFactory);
    }
}

# AuthorizationServerConfig配置如下
