前言

在前面的笔记分享中，我们知道了OAuth 2是什么，他是一个第三方登录的授权协议。为什么要使用 OAuth 2，因为现在是分布式架构，对客户来说，是一个系统，但是后台实现是多个微服务，客户一次登录，应该要能访问到不同的微服务。今天我们接着学习 OAuth2 的实战。

工程结构;

授权服务器：颁发和验证令牌

提供需要令牌才能访问的服务

依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-security</artifactId>
</dependency>

授权服务器配置

oauth2 配置类继承

AuthorizationServerConfigurerAdapter

开启授权服务器

@EnableAuthorizationServer

客户端信息配置

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients
                .inMemory()
                .withClient(CLIENT_ID)
                .secret(SECRET_CHAR_SEQUENCE)
                .autoApprove(false)
                .redirectUris("http://127.0.0.1:8084/cms/login") //重定向uri
                .scopes(ALL)
                .accessTokenValiditySeconds(ACCESS_TOKEN_VALIDITY_SECONDS)
                .authorizedGrantTypes(AUTHORIZATION_CODE, IMPLICIT, GRANT_TYPE_PASSWORD, CLIENT_CREDENTIALS);
    }

存储令牌

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager).tokenStore(memoryTokenStore());
    }
    @Bean
    public TokenStore memoryTokenStore() {
        return new InMemoryTokenStore();
    }

oauth2端点权限

    /**
     * 认证服务器的安全配置
     *
     * @param security
     * @throws Exception
     */
    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security
                //  开启/oauth/check_token验证端口认证权限访问，checkTokenAccess("isAuthenticated()")设置授权访问
                .checkTokenAccess("permitAll()")
                //允许表单认证
                .allowFormAuthenticationForClients();
    }

SecurityConfig配置类继承

WebSecurityConfigurerAdapter

开启Spring Security

@EnableWebSecurity

设置用户角色数据内存存储

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {    //auth.inMemoryAuthentication()
        auth.inMemoryAuthentication()
                .withUser("lxs")
                .password("{noop}123") //使用springsecurity5，需要加上{noop}指定使用NoOpPasswordEncoder给DelegatingPasswordEncoder去校验密码
                .roles("admin");
    }

放行静态资源

    @Override
    public void configure(WebSecurity web) throws Exception {
        //解决静态资源被拦截的问题
//        web.ignoring().antMatchers("/asserts/**");
    }

授权资源全局配置

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .formLogin().permitAll()
                .and().logout().logoutUrl("/logout").logoutSuccessUrl("/")
                .and().authorizeRequests().antMatchers("/oauth/**", "/login/**", "/logout/**", "/api/**").permitAll()
                .anyRequest().authenticated()
                // 关闭跨域保护;
                .and().csrf().disable();
    }

资源服务器配置

Oauth2配置类继承

ResourceServerConfigurerAdapter

@Configuration
@EnableResourceServer
public class Oauth2ResourceServerConfiguration extends
    ResourceServerConfigurerAdapter {

  private static final String CHECK_TOKEN_URL = "http://localhost:8888/oauth/check_token";

  @Override
  public void configure(ResourceServerSecurityConfigurer resources) {
    RemoteTokenServices tokenService = new RemoteTokenServices();
    // 授权服务器令牌校验地址
    tokenService.setCheckTokenEndpointUrl(CHECK_TOKEN_URL);
    // 客户端信息
    tokenService.setClientId("cms");
    tokenService.setClientSecret("secret");

    resources.tokenServices(tokenService);
  }

}

Security配置类继承

WebSecurityConfigurerAdapter

@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    // 授权拦截路径
    http.authorizeRequests().antMatchers("/**").authenticated();
    // 禁用CSRF，关闭跨域保护
    http.csrf().disable();
  }
}
