server:
  port: 8084
  servlet:
    context-path: /cms


@SpringBootApplication
@EnableResourceServer
public class CmsApplication {

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

}

资源服务器配置类

@Configuration
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();

//    tokenService.setRestTemplate(restTemplate);

    tokenService.setCheckTokenEndpointUrl(CHECK_TOKEN_URL);

//    DefaultAccessTokenConverter defaultAccessTokenConverter = new DefaultAccessTokenConverter();
//    defaultAccessTokenConverter.setUserTokenConverter(new CustomUserAuthenticationConverter());
//    tokenService.setAccessTokenConverter(defaultAccessTokenConverter);

    resources.tokenServices(tokenService);
  }

}

spring security配置类

@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests().antMatchers("/**").authenticated();
    // 禁用CSRF
    http.csrf().disable();
  }
}

测试用controller

@RestController
public class HelloController {

    @GetMapping("/getCurrentUser")
    public Object getCurrentUser(Authentication authentication) {
        return authentication;
    }

    @GetMapping("/index")
    public String index() {
        return "index";
    }
}

Oauth2授权模式

授权码模式

• 认证服务授权码配置

• 访问授权链接，在浏览器访问就可以，授权码模式response_type参数传code：

  Get请求：
  http://localhost:8888/oauth/authorize?client_id=cms&client_secret=secret&response_type=code

因为没登录，所以会返回SpringSecurity的默认登录页面，具体代码是 http .formLogin().permitAll(); ，如果要弹窗登录的，可以配置 http.httpBasic(); ，这种配置是没有登录页面的，自定义登录页面可以这样配置http.formLogin().loginPage("/login").permitAll() ，参考OAuth2Config代码

• 拿到授权码后，申请令牌。 使用Postman申请授权码

此链接需要使用 http Basic认证。 什么是http Basic认证？ http协议定义的一种认证方式，将客户端id
和客户端密码按照“客户端ID:客户端密码”的格式拼接，并用base64编 码，放在header中请求服务端，
一个例子： Authorization：Basic WGNXZWJBcHA6WGNXZWJBcHA=WGNXZWJBcHA6WGNXZWJBcHA= 是用户名:密码的base64编码。认证失败服务端返回 401 Unauthorized

客户端Id和客户端密码会匹配数据库oauth_client_details表中的客户端id及客户端密码

• Spring Security Oauth2提供校验令牌的端点

  Get:
  http://localhost:8888/oauth/check_token?token=171ce96e-7492-4a27-becd- 8ccbdc69666b

• 使用令牌

密码模式

• 申请令牌
  
  
  
  
  客户端Id和客户端密码会匹配数据库oauth_client_details表中的客户端id及客户端密码
  
  

• 令牌校验

  Get:
  http://localhost:8888/oauth/check_token?token=1e628350-5711-4983-9b10- da7a7e8b9558

• 使用令牌
  

简化模式

简化模式（implicit grant type）不通过第三方应用程序的服务器，直接在浏览器中向认证服务器申请令牌，跳过了"授权码"这个步骤，因此称简化模式。简化模式是相对于授权码模式而言的

• 认证服务授权码配置

• 申请令牌

  Get请求：
  http://localhost:8888/oauth/authorize?client_id=cms&redirect_uri=http://127.0.0.1:8084/cms/login&response_type=token&s cope=all

• 令牌校验

  Get:
  http://localhost:8888/oauth/check_token?token=171ce96e-7492-4a27-becd- 8ccbdc69666b

• 使用令牌

简化模式和授权码模式的区别

授权码模式User-agent（浏览器）只是持有授权码（code）使用授权码获得令牌，授权码，只能校验一次，这样即使授权码泄露，令牌相对安全，而简化模式由user agent(浏览器)，直接持有令牌，相对不安全

客户端模式

客户端模式（client credentials）：客户端模式（client credentials）适用于没有前端的命令行应用，即在命令行下请求令牌

• 认证服务授权码配置

• 申请令牌

  post请求：
  http://localhost:8888/oauth/token?client_id=cms&client_secret=secret&grant_type=client_credentials&scope=all

• 令牌校验

  Get:
  http://localhost:8888/oauth/check_token?token=171ce96e-7492-4a27-becd- 8ccbdc69666b

• 使用令牌

令牌存储方式

JWT方式存储token 案例

认证服务器采用JwtTokenStore处理token，也就是认证服务器器不存储token，实现纯粹的无状态token管理，同时应该spring security oauth2的脚本规范，使用数据库方式存储客户端信息

非对称加密

资源服务授权流程

• 传统授权流程
  

• 公钥私钥授权流程
  
  

生成私钥公钥

用keytool工具生成公钥私钥证书,keytool工具是JDK自带的工具

• 创建一个文件夹，在该文件夹下执行如下命令行：

  keytool -genkeypair -alias makeFile-keyalg RSA -keypass makeFile-keystore makeFile.jks -storepass makeFile

• 查询证书信息

  keytool -list -keystore kaikeba.jks

• 删除

  keytool -delete -alias kaikeba -keystore kaikeba.jsk

导出公钥

openssl是一个加解密工具包，这里使用openssl来导出公钥信息

cmd进入kaikeba.jks文件所在目录执行如下命令(如下命令在windows下执行，会把-变成中文方式，将它改成英文的-)：

keytool -list -rfc --keystore kaikeba.jks | openssl x509 -inform pem -pubkey

JWT令牌

使用私钥生成令牌

//生成一个jwt令牌
    @Test
    public void testCreateJwt() throws Exception {
        //证书文件
        String key_location = "kaikeba.jks";
        //密钥库密码
        String keystore_password = "kaikeba";
        //访问证书路径
        ClassPathResource resource = new ClassPathResource(key_location);
        //密钥工厂
        KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(resource, keystore_password.toCharArray());
        //密钥的密码，此密码和别名要匹配
        String keypassword = "kaikeba";
        //密钥别名
        String alias = "kaikeba";
        //密钥对（密钥和公钥）
        KeyPair keyPair = keyStoreKeyFactory.getKeyPair(alias, keypassword.toCharArray());
        //私钥
        RSAPrivateKey aPrivate = (RSAPrivateKey) keyPair.getPrivate();
        //定义payload信息
        Map<String, Object> tokenMap = new HashMap<String, Object>();
        tokenMap.put("id", "123");
        tokenMap.put("name", "mrt");
        tokenMap.put("roles", "r01,r02");
        tokenMap.put("ext", "1");
        //生成jwt令牌
        Jwt jwt = JwtHelper.encode(new ObjectMapper().writeValueAsString(tokenMap), new RsaSigner(aPrivate));
        //取出jwt令牌
        String token = jwt.getEncoded();
        System.out.println("token=" + token);
    }

解析令牌

	//资源服务使用公钥验证jwt的合法性，并对jwt解码
    @Test
    public void testVerify() {
        //jwt令牌
        String token
                = "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHQiOiIxIiwicm9sZXMiOiJyMDEscjAyIiwibmFtZSI6Im1ydCIsImlkIjoiMTIzIn0.OXzFObxUq35--qgvBy4mnBXx-f9mfpYMczTfAfH7yHM05W-oJ6RPmLPonZsFlZMd8JBdLm6iz_TN6b4ynO0heCBsyML2ZLx0sxhgE28mhztDXj2GHbWu3kwsRzU9Pbgy-CO3FIG0Iw-aIkFSivaaLsCju5oOLxGB825ueI5hM58sPLLykZPAaU6DcVY3X1sfpWDIQ7G7JkCoP3rH385Vcmg1VBJVIwVxEn4TXHtWqre9lgK-T7D4zXlhScB57gv9OfcbebNm8tI2Rew1IHmOCeKf5CKAiSCv5d26LhLPKqvGBQ5Cy67JM58X2T-4LvgQeQR6TZmiiSr7fLnEkNe9KQ";
        //公钥
        String publickey = "-----BEGIN PUBLIC KEY-----MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAwtYpjt7NtpS1B51x6PUK7ryvKySK4VQi7KUCGBm6kisErNM+FwdgKMbpQxTtWoYyXfQsWwuhBW45+uF+Z5DUDaLtHlMV55eA5fkGLFZ1F9ppZC+2Etsy1CyPqA0Mx8R0/HbMB1no4KTlQpqST7JjCdtwLWqUd68zDlfToIsWB1fHuYHbH/DCGUBmZb+16805/SjWkYvj3B6F+WJ8Gm47/OJBH+wo7k4GWZ7OXdMcNnYWMyBfa4abjo7cxjoHL2fDanS6And4Sh3cZEJde4WgXsEktvR/EaZR7CeQzwzOg47+5cCcFSYgmVfpDyLsBnFkG3WFs/qZ3yPzy+DQKLIF2wIDAQAB-----END PUBLIC KEY-----";
        //校验jwt
        Jwt jwt = JwtHelper.decodeAndVerify(token, new RsaVerifier(publickey));
        //获取jwt原始内容
        String claims = jwt.getClaims();
        System.out.println(claims);
        //jwt令牌
        String encoded = jwt.getEncoded();
        System.out.println(encoded);

JWT方式存储token 完善

security-service微服务

<!--oauth依赖--> 
<dependency> 
	<groupId>org.springframework.cloud</groupId> 
	<artifactId>spring-cloud-starter-oauth2</artifactId> 
</dependency>


security:
  oauth2:
    resource:
      jwt:
        key-uri: http://localhost:9098/oauth/token_key	#如果使用JWT，可以获取公钥用于 token 的验签

配置使用公钥校验令牌

@Configuration
public class JwtConfig {

    public static final String public_cert = "public.key";

    @Autowired
    private JwtAccessTokenConverter jwtAccessTokenConverter;

    @Bean
    @Qualifier("tokenStore")
    public TokenStore tokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter);
    }

    @Bean
    protected JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        Resource resource =  new ClassPathResource(public_cert);

        String publicKey;
        try {
            publicKey = new String(FileCopyUtils.copyToByteArray(resource.getInputStream()));
        }catch (IOException e) {
            throw new RuntimeException(e);
        }

        converter.setVerifierKey(publicKey); //设置校验公钥

        converter.setSigningKey("kaikeba"); //设置证书签名密码，否则报错

        return converter;
    }
}

配置资源服务器

@Configuration
@EnableResourceServer
@EnableGlobalMethodSecurity(prePostEnabled = true)//激活方法上的PreAuthorize注解
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

    @Autowired
    private TokenStore tokenStore;

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .authorizeRequests()
                .antMatchers("/user/**", "/security/user/**").permitAll()
                .antMatchers("/book/**").hasRole("ADMIN") //用于测试
                .antMatchers("/**").authenticated();
    }

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        resources.tokenStore(tokenStore);
    }
}

创建测试用的Controller

@RestController
public class TestEndPointController {

    Logger logger = LoggerFactory.getLogger(TestEndPointController.class);

    @GetMapping("/product/{id}")
    public String getProduct(@PathVariable String id) {
        return "product id : " + id;
    }

    @GetMapping("/order/{id}")
    public String getOrder(@PathVariable String id) {
        return "order id : " + id;
    }

    @GetMapping("/book/{id}")
    public String getBook(@PathVariable String id) {
        return "book id : " + id;
    }

    @GetMapping("/anno/{id}")
    @PreAuthorize("hasRole('ROLE_ADMIN')")
    public String getAnno(@PathVariable String id) {
        return "admin id :" + id;
    }

    @RequestMapping("/hello")
    @PreAuthorize("hasAnyAuthority('ROLE_ADMIN')")
    public String hello() {
        return "hello you ...";
    }


    @GetMapping("/getPrinciple")
    public OAuth2Authentication getPrinciple(OAuth2Authentication oAuth2Authentication, Principal principal, Authentication authentication) {
        logger.info(oAuth2Authentication.getUserAuthentication().getAuthorities().toString());
        logger.info(oAuth2Authentication.toString());
        logger.info("principal.toString() " + principal.toString());
        logger.info("principal.getName() " + principal.getName());
        logger.info("authentication: " + authentication.getAuthorities().toString());

        return oAuth2Authentication;
    }

}

SpringSecurity权限控制

• UserDetailServiceImpl

在每个微服务中，需要获取用户的角色，然后根据角色识别是否允许操作指定的方法，Spring Security中定义了四个支持权限控制的表达式注解，分别是 @PreAuthorize 、 @PostAuthorize 、 @PreFilter 和@PostFilter 。其中前两者可以用来在方法调用前或者调用后进行权限检查，后两者可以用来对集合类型的参数或者返回值进行过滤。在需要控制权限的方法上，我们可以添加@PreAuthorize 注解，用于方法执行前进行权限检查，校验用户当前角色是否能访问该方法。

• 开启@PreAuthorize

ResourceServerConfiguration类上添加 @EnableGlobalMethodSecurity 注
解，用于开启@PreAuthorize的支持

• ** TestEndPointController 类的测试方法上添加权限控制注解 @PreAuthorize**

• 同时也可以在资源服务配置类中配置，进行权限控制

JWT方式存储token 再完善

• legou-security.yml

  @Bean
  PasswordEncoder passwordEncoder() {
  	return new BCryptPasswordEncoder();
      //return PasswordEncoderFactories.createDelegatingPasswordEncoder();//兼容多种密码的加密方式
  }
  

  }

• service密码加密

  @Override
  @Transactional(readOnly = false)
  public boolean saveOrUpdate(User entity) {
  //添加时，设置lock=false
  if (null == entity.getId()){
  entity.setLock(false);
  }

  	entity.setPassword(passwordEncoder.encode(entity.getPassword()));
  

  // passwordHelper.encryptPassword(entity); //加密md5(md5(password,salt))

  	boolean result = super.saveOrUpdate(entity);
  
  	((UserDao) getBaseMapper()).deleteRoleByUser(entity.getId());
  
  	Long[] roleIds = entity.getRoleIds();
  	if (null != roleIds) {
  		for (Long roleId : roleIds) {
  			((UserDao) getBaseMapper()).insertRoleAndUser(roleId, entity.getId());
  		}
  	}
  	return result;
  
  }
