【SpringBoot】集成SpringSecurity+JWT实现多服务单点登录，原来这么easy

Spring Boot+Spring Security+JWT实现单点登录

一.概念

1.1.SSO

介绍：

• 单点登录(SingleSignOn，SSO)，当用户在身份认证服务器上登录一次以后，即可获得访问单点登录系统中其他关联系统和应用软件的权限，同时这种实现是不需要管理员对用户的登录状态或其他信息进行修改的，这意味着在多个应用系统中，用户只需一次登录就可以访问所有相互信任的应用系统。这种方式减少了由登录产生的时间消耗，辅助了用户管理，是目前比较流行的一种分布式登录方式。

SSO实现流程：

• 在分布式项目中，每台服务器都有各自独立的session，而这些session之间是无法直接共享资源的，所以，session通常不能被作为单点登录的技术方案。最合理的单点登录方案流程如下图所示：
  

单点登录的实现分2部分：

• 用户认证：客户端向认证服务器发起认证请求，认证服务器给客户端返回令牌token， 主要在认证服务器中完成，即图中的A系统，注意认证服务器只能有一个
• 身份校验： 客户端携带token去访问其他资源服务器时，在资源服务器中要对token的真伪进行检验，主要在资源服务器中完成，即图中的B系统，这里B系统可以有很多个

1.2.JWT

什么是JWT

• 【JavaWeb】关于JWT做认证授权的十万个理由(JSON Web Token)

1.3.RSA

非对称加密算法

• 服务提供方生成两把密钥（公钥和私钥）。私钥隐秘保存，公钥公开,下发给信任客户端
• 调用方获取提供方的公钥，然后用它对信息加密。
• 提供方接收到调用加密后的信息后，用私钥解密。

RSA算法

• 一直是最广为使用的"非对称加密算法"。毫不夸张地说，只要有计算机网络的地方，就有RSA算法。这种算法非常可靠，密钥越长，它就越难破解。根据已经披露的文献，目前被破解的最长RSA密钥是768个二进制位。也就是说，长度超过768位的密钥，还无法破解（至少没人公开宣布）。因此可以认为，1024位的RSA密钥基本安全，2048位的密钥极其安全。

RSA使用流程：

• 生成两把密钥：私钥和公钥，私钥保存起来，公钥可以下发给信任客户端
  • 私钥加密，持有私钥或公钥才可以解密
  • 公钥加密，持有私钥才可解密
• 因此，认证服务一般存放私钥和公钥，而资源服务一般存放公钥。私钥负责加密，公钥负责解密。

二.思路

1.分析集中式认证流程

• 用户认证：使用UsernamePasswordAuthenticationFilter过滤器中attemptAuthentication()实现认证功能，该过滤器父类中successfulAuthentication()实现认证成功后的操作。
• 身份校验：使用BasicAuthenticationFilter过滤器中doFilterInternal()验证是否登录，以决定能否进入后续过滤器。

2.分析分布式认证流程

• 用户认证：分布式项目多数是前后端分离的架构，需要修改UsernamePasswordAuthenticationFilter过滤器中attemptAuthentication()，让其能够接收请求体。另外，默认successfulAuthentication()在认证通过后，是把用户信息直接放入session就完事了

  • 处理方式：修改successfulAuthentication()，在认证通过后生成token并返回给用户。

• 身份校验： 原来BasicAuthenticationFilter过滤器中doFilterInternal()校验用户是否登录，就是看session中是否有用户信息

  • 处理方式：校验逻辑修改为，验证用户携带的token合法，并解析出用户信息，交给SpringSecurity，以便于后续的授权功能可以正常使用。

三.工程介绍

1.介绍父工程

因为本案例需要创建多个系统，所以我们使用maven聚合工程来实现，首先创建一个父工程，导入springboot的父依赖即可

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.4.2</version>
        <relativePath/>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.oyjp</groupId>
    <artifactId>spring-boot-security-sso-parent</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>pom</packaging>
    <description>通用模块</description>

    <modules>
        <module>sso-common</module><!--通用子模块-->
        <module>sso-auth-server</module><!--认证服务子模块-->
        <module>sso-source-product</module><!--产品资源服务子模块-->
        <module>sso-source-order</module><!--订单资源服务子模块-->
    </modules>

该工程由四个子模块组成，一个认证服务模块，一个通用模块，一个订单资源模块，一个产品资源模块

2.导入数据库

            response.setHeader("Access-Control-Allow-Origin", "*");
            response.setHeader("Cache-Control", "no-cache");
            response.setCharacterEncoding("UTF-8");
            response.setContentType("application/json");
            response.setStatus(status);
            byte[] bytes = JsonUtils.toString(new Result(status, msg, null)).getBytes();
            OutputStream out = response.getOutputStream();
            out.write(bytes);
        } catch (Exception e) {
            logger.error("响应出错：" + msg, e);
        }
    }
}

4.生成密钥

• 使用密钥在指定位置生成公钥/私钥文件

public class RsaUtilsTest {
    private String publicFile = "E:\\auth_key\\rsa_key.pub";
    private String privateFile = "E:\\auth_key\\rsa_key";
    private String secret = "JianpengOuYangSecret";

    @Test
    public void generateKey() throws Exception {
        RsaUtils.generateKey(publicFile, privateFile, secret, 2048);
    }
}

五 认证服务

注意：本章节所有操作均在sso-auth-server中进行。

1.导入依赖

<dependencies>
        <!--web-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!--springSecurity-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

        <!--mybatis、mysql-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.4</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.49</version>
        </dependency>

        <!--引入通用子模块-->
        <dependency>
            <groupId>com.oyjp</groupId>
            <artifactId>sso-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
</dependencies>

2.创建配置文件

server:
  port: 9001
  servlet:
    application-display-name: sso-auth-server

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/security_test2?useSSL=false
    username: root
    password: root

mybatis:
  type-aliases-package: com.oyjp.domain
  configuration:
    map-underscore-to-camel-case: true

logging:
  level:
    com.oyjp: debug

#自定义属性，配置私钥路径
rsa:
  key:
    privateKeyPath: E:\auth_key\rsa_key

3.编写读取公钥的配置类

@Data
@ConfigurationProperties(prefix = "rsa.key", ignoreInvalidFields = true)
public class RsaKeyProperties {
    private String publicKeyPath;
    private String privateKeyPath;

    private PublicKey publicKey;
    private PrivateKey privateKey;

    /**
     * 该方法用于初始化公钥和私钥的内容
     */
    @PostConstruct
    public void loadRsaKey() throws Exception {
        if (publicKeyPath != null) {
            publicKey = RsaUtils.getPublicKey(publicKeyPath);
        }
        if (privateKeyPath != null) {
            privateKey = RsaUtils.getPrivateKey(privateKeyPath);
        }
    }
}

4.编写启动类

@SpringBootApplication
@EnableConfigurationProperties(RsaKeyProperties.class) //启动时加载配置类
public class AuthServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(AuthServerApplication.class, args);
    }
}

5.编写实体类

用户类实现springSecurity的UserDetails 接口

@Data
public class SysUser implements UserDetails {
    private Integer id;
    private String username;
    private String password;
    private Integer status;
    private List<SysRole> sysRoles;

    @JsonIgnore
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return sysRoles;
    }

    /**
     * 是否账号已过期
     */
    @JsonIgnore
    @Override
    public boolean isAccountNonExpired() {
        return status != 1;
    }

    /**
     * 是否账号已被锁
     */
    @JsonIgnore
    @Override
    public boolean isAccountNonLocked() {
        return status != 2;
    }

    /**
     * 是否凭证已过期
     */
    @JsonIgnore
    @Override
    public boolean isCredentialsNonExpired() {
        return status != 3;
    }

    /**
     * 是否账号已禁用
     */
    @JsonIgnore
    @Override
    public boolean isEnabled() {
        return status != 4;
    }
}

角色类实现springSecurity的GrantedAuthority接口

@Data
public class SysRole implements GrantedAuthority {
    private Integer id;
    private String name;
    private String desc;

    @JsonIgnore
    @Override
    public String getAuthority() {
        return name;
    }
}

6.编写映射接口

查用户信息

@Mapper
public interface SysUserMapper {
    //根据用户名称查询所对应的用户信息
    @Select("select * from `sys_user` where `username` = #{username}")
    @Results({
            //主键字段映射，property代表Java对象属性，column代表数据库字段
            @Result(property = "id", column = "id", id = true),
            //普通字段映射，property代表Java对象属性，column代表数据库字段
            @Result(property = "username", column = "username"),
            @Result(property = "password", column = "password"),
            @Result(property = "status", column = "status"),
            //角色列表映射，根据用户id查询该用户所对应的角色列表sysRoles
            @Result(property = "sysRoles", column = "id",
                    javaType = List.class,
                    many = @Many(select = "com.oyjp.mapper.SysRoleMapper.findByUid")
            )
    })
    SysUser findByUsername(String username);
}

查角色信息

@Mapper
public interface SysRoleMapper {
    //根据用户编号查询角色列表
    @Select("select * from `sys_role` where id in (" +
            "  select rid from `sys_user_role` where uid = #{uid}" +
            ")")
    List<SysRole> findByUid(Integer uid);
}

7.编写服务接口

实现springSecurity的UserDetailsService 接口，重新loadUserByUsername()

public interface SysUserDetailsService extends UserDetailsService {

}

@Service
@Transactional
public class SysUserDetailsServiceImpl implements SysUserDetailsService {
    @Autowired(required = false)
    private SysUserMapper sysUserMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        //根据用户名去数据库中查询指定用户，这就要保证数据库中的用户的名称必须唯一，否则将会报错
        SysUser sysUser = sysUserMapper.findByUsername(username);
        //如果没有查询到这个用户，说明数据库中不存在此用户，认证失败，此时需要抛出用户账户不存在
        if (sysUser == null) {
            throw new UsernameNotFoundException("user not exist.");
        }
        return sysUser;
    }
}

8.编写认证过滤器

/**
 * 认证过滤器
 *
 */
@Slf4j
public class JwtAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
    private AuthenticationManager authenticationManager;
    private RsaKeyProperties prop;

    public JwtAuthenticationFilter(AuthenticationManager authenticationManager, RsaKeyProperties prop) {
        this.authenticationManager = authenticationManager;
        this.prop = prop;
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        SysUser sysUser = RequestUtils.read(request, SysUser.class);
        assert sysUser != null;
        String username = sysUser.getUsername();
        username = username != null ? username : "";
        String password = sysUser.getPassword();
        password = password != null ? password : "";
        UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password);
        return authenticationManager.authenticate(authRequest);
    }

    /**
     * 认证成功所执行的方法
     */
    @Override
    protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication authResult) throws IOException, ServletException {
        SysUser sysUser = new SysUser();
        sysUser.setUsername(authResult.getName());
        sysUser.setSysRoles(new ArrayList(authResult.getAuthorities()));
        String token = JwtUtils.generateTokenExpireInMinutes(sysUser, prop.getPrivateKey(), 24 * 60);
        response.addHeader("Authorization", "Bearer " + token);
        ResponseUtils.write(response, HttpServletResponse.SC_OK, "用户认证通过！");
    }

    /**
     * 认证失败所执行的方法
     */
    @Override
    protected void unsuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response, AuthenticationException failed) throws IOException, ServletException {
        //清理上下文
        SecurityContextHolder.clearContext();
        log.error("AuthenticationException",failed);
        //判断异常类
        if (failed instanceof InternalAuthenticationServiceException) {
            ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "认证服务不正常！");
        } else if (failed instanceof UsernameNotFoundException) {
            ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "用户账户不存在！");
        } else if (failed instanceof BadCredentialsException) {
            ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "用户密码是错的！");
        } else if (failed instanceof AccountExpiredException) {
            ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "用户账户已过期！");
        } else if (failed instanceof LockedException) {
            ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "用户账户已被锁！");
        } else if (failed instanceof CredentialsExpiredException) {
            ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "用户密码已失效！");
        } else if (failed instanceof DisabledException) {
            ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "用户账户已被锁！");
        }
    }
}

9.编写安全配置类

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private SysUserDetailsService sysUserDetailsService;
    @Autowired
    private RsaKeyProperties prop;

    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    public AuthenticationProvider daoAuthenticationProvider() {
        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
         //指定认证对象的来源
        daoAuthenticationProvider.setUserDetailsService(sysUserDetailsService);
         //指定密码编码的来源
        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
        daoAuthenticationProvider.setHideUserNotFoundExceptions(false);
        return daoAuthenticationProvider;
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(daoAuthenticationProvider());
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        //禁用csrf保护机制
        http.csrf().disable();
        //禁用cors保护机制
        http.cors().disable();
        //禁用session会话
        http.sessionManagement().disable();
        //禁用form表单登录
        http.formLogin().disable();
        //增加自定义认证过滤器（认证服务需要配置）
        http.addFilter(new JwtAuthenticationFilter(super.authenticationManager(), prop));
    }
}

六 订单资源

资源服务可以有很多个，这里只拿订单服务为例，记住，资源服务中只能通过公钥验证认证。不能签发token！

• 注意：本章节所有操作均在sso-source-order中进行。

1.导入依赖

        <!--web-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!--springSecurity-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

        <!--mybatis、mysql-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.4</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.49</version>
        </dependency>

        <!--引入通用子模块-->
        <dependency>
            <groupId>com.oyjp</groupId>
            <artifactId>sso-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

2.编写配置文件

server:
  port: 9002
  servlet:
    application-display-name: sso-source-order

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/security_test2?useSSL=false
    username: root
    password: root

mybatis:
  type-aliases-package: com.oyjp.domain
  configuration:
    map-underscore-to-camel-case: true
logging:
  level:
    com.oyjp: debug

#自定义属性，配置公钥路径
rsa:
  key:
    publicKeyPath: E:\auth_key\rsa_key.pub

3.编写读取公钥的配置类

@Data
@ConfigurationProperties(prefix = "rsa.key", ignoreInvalidFields = true)
public class RsaKeyProperties {
    private String publicKeyPath;
    private String privateKeyPath;

    private PublicKey publicKey;
    private PrivateKey privateKey;

    /**
     * 该方法用于初始化公钥和私钥的内容
     */
    @PostConstruct
    public void loadRsaKey() throws Exception {
        if (publicKeyPath != null) {
            publicKey = RsaUtils.getPublicKey(publicKeyPath);
        }
        if (privateKeyPath != null) {
            privateKey = RsaUtils.getPrivateKey(privateKeyPath);
        }
    }
}

5.编写验证过滤器

/**
 * 验证过滤器
 *
 * @author oyjp
 */
public class JwtVerificationFilter extends BasicAuthenticationFilter {
    private RsaKeyProperties prop;

    public JwtVerificationFilter(AuthenticationManager authenticationManager, RsaKeyProperties prop) {
        super(authenticationManager);
        this.prop = prop;
    }

    @Override
    public void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws IOException, ServletException {
        try {
            String header = request.getHeader("Authorization");
            if (header == null || !header.startsWith("Bearer ")) {
                //如果token的格式错误，则提示用户非法登录
                chain.doFilter(request, response);
                ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "用户非法登录！");
            } else {
                //如果token的格式正确，则先要获取到token
                String token = header.replace("Bearer ", "");
                //使用公钥进行解密然后来验证token是否正确
                Payload<SysUser> payload = JwtUtils.getInfoFromToken(token, prop.getPublicKey(), SysUser.class);
                SysUser sysUser = payload.getUserInfo();
                if (sysUser != null) {
                    UsernamePasswordAuthenticationToken authResult = new UsernamePasswordAuthenticationToken(sysUser.getUsername(), null, sysUser.getAuthorities());
                    SecurityContextHolder.getContext().setAuthentication(authResult);
                    chain.doFilter(request, response);
                } else {
                    ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "用户验证失败！");
                }
            }
        } catch (ExpiredJwtException e) {
            ResponseUtils.write(response, HttpServletResponse.SC_FORBIDDEN, "请您重新登录！");
        }
    }
}

6.编写安全配置类

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private RsaKeyProperties prop;

    @Override
    public void configure(HttpSecurity http) throws Exception {
        //禁用csrf保护机制
        http.csrf().disable();
        //禁用cors保护机制
        http.cors().disable();
        //禁用session会话
        http.sessionManagement().disable();
        //禁用form表单登录
        http.formLogin().disable();
        //增加自定义验证过滤器（资源服务需要配置）
        http.addFilter(new JwtVerificationFilter(super.authenticationManager(), prop));
    }
}

7.全局异常处理

@RestControllerAdvice
public class GlobalExceptionHandler {
    @ExceptionHandler(AccessDeniedException.class)
    public Result accessDeniedException() {
        return new Result(403, "用户权限不足！", null);
    }

    @ExceptionHandler(RuntimeException.class)
    public Result serverException() {
        return new Result(500, "服务出现异常！", null);
    }
}

8.订单资源控制器

@RestController
@RequestMapping("/order")
public class OrderController {
    @Secured({"ROLE_ADMIN","ROLE_ORDER"})
    @RequestMapping("/info")
    public String info() {
        return "Order Controller ...";
    }
}

9.启动类

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

七.产品资源

直接复制订单服务，目录名称改为sso-source-product，然后修改yml配置文件、controller、启动类

1.修改yml配置文件

• 改一下application-display-name、port 即可

server:
  port: 9003
  servlet:
    application-display-name: sso-source-product

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/security_test2?useSSL=false
    username: root
    password: root

mybatis:
  type-aliases-package: com.oyjp.domain
  configuration:
    map-underscore-to-camel-case: true
logging:
  level:
    com.oyjp: debug

#自定义属性，配置公钥路径
rsa:
  key:
    publicKeyPath: E:\auth_key\rsa_key.pub

2.产品资源控制器

• 编写产品的controller逻辑

@RestController
@RequestMapping("/product")
public class ProductController {
    @Secured({"ROLE_ADMIN", "ROLE_PRODUCT"})
    @RequestMapping("/info")
    public String info() {
        return "Productr Controller ...";
    }
}

3.启动类

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

八 终极测试

1.认证服务测试

2.订单资源测试

3.产品资源测试

4.用户状态测试
