1. 前言

Apache Shiro 是一个功能强大且易于应用的 Java 平安框架，提供了认证，受权，加密，和会话治理。

Shiro 有三大外围组件：

  • Subject： 即以后用户，在权限治理的应用程序里往往须要晓得谁可能操作什么，谁领有操作该程序的权力，shiro 中则须要通过 Subject 来提供根底的以后用户信息，Subject 不仅仅代表某个用户，与以后利用交互的任何货色都是 Subject，如网络爬虫等。所有的 Subject 都要绑定到 SecurityManager 上，与 Subject 的交互实际上是被转换为与 SecurityManager 的交互。
  • SecurityManager： 即所有 Subject 的管理者，这是 Shiro 框架的外围组件，能够把他看做是一个 Shiro 框架的全局治理组件，用于调度各种 Shiro 框架的服务。作用相似于 SpringMVC 中的 DispatcherServlet，用于拦挡所有申请并进行解决。
  • Realm： Realm 是用户的信息认证器和用户的权限物证器，咱们须要本人来实现 Realm 来自定义的治理咱们本人零碎外部的权限规定。SecurityManager 要验证用户，须要从 Realm 中获取用户。能够把 Realm 看做是数据源。

2. 数据库设计

4.5 Service 层

4.5.1 PermissionServiceImpl.java

@Service
public class PermissionServiceImpl implements PermissionService {

    @Autowired
    private PermissionMapper permissionMapper;

    @Override
    public List<String> findByRoleId(List<Integer> roleIds) {return permissionMapper.findByRoleId(roleIds);
    }
}

4.5.2 RoleServiceImpl.java

    @Autowired
    private RoleMapper roleMapper;

    @Override
    public List<Role> findRoleByUserId(Integer id) {return roleMapper.findRoleByUserId(id);
    }
}

4.5.3 UserServiceImpl.java

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public User findByAccount(String account) {return userMapper.findByAccount(account);
    }
}

4.6. 零碎返回状态枚举与包装函数

4.6.1 ServerResponseEnum.java

@AllArgsConstructor
@Getter
public enum ServerResponseEnum {SUCCESS(0, "胜利"),
    ERROR(10, "失败"),

    ACCOUNT_NOT_EXIST(11, "账号不存在"),
    DUPLICATE_ACCOUNT(12, "账号反复"),
    ACCOUNT_IS_DISABLED(13, "账号被禁用"),
    INCORRECT_CREDENTIALS(14, "账号或明码谬误"),
    NOT_LOGIN_IN(15, "账号未登录"),
    UNAUTHORIZED(16, "没有权限")
    ;
    Integer code;
    String message;
}

4.6.2 ServerResponseVO.java

@Getter
@Setter
@NoArgsConstructor
public class ServerResponseVO<T> implements Serializable {
    private static final long serialVersionUID = -1005863670741860901L;
    // 响应码
    private Integer code;

    // 形容信息
    private String message;

    // 响应内容
    private T data;

    private ServerResponseVO(ServerResponseEnum responseCode) {this.code = responseCode.getCode();
        this.message = responseCode.getMessage();}

    private ServerResponseVO(ServerResponseEnum responseCode, T data) {this.code = responseCode.getCode();
        this.message = responseCode.getMessage();
        this.data = data;
    }

    private ServerResponseVO(Integer code, String message) {
        this.code = code;
        this.message = message;
    }

    /**
     * 返回胜利信息
     * @param data      信息内容
     * @param <T>
     * @return
     */
    public static<T> ServerResponseVO success(T data) {return new ServerResponseVO<>(ServerResponseEnum.SUCCESS, data);
    }

    /**
     * 返回胜利信息
     * @return
     */
    public static ServerResponseVO success() {return new ServerResponseVO(ServerResponseEnum.SUCCESS);
    }

    /**
     * 返回错误信息
     * @param responseCode      响应码
     * @return
     */
    public static ServerResponseVO error(ServerResponseEnum responseCode) {return new ServerResponseVO(responseCode);
    }
}

4.7 对立异样解决

当用户身份认证失败时，会抛出 UnauthorizedException，咱们能够通过对立异样解决来解决该异样 

@RestControllerAdvice
public class UserExceptionHandler {@ExceptionHandler(UnauthorizedException.class)
    @ResponseStatus(HttpStatus.UNAUTHORIZED)
    public ServerResponseVO UnAuthorizedExceptionHandler(UnauthorizedException e) {return ServerResponseVO.error(ServerResponseEnum.UNAUTHORIZED);
    }
}

5. 集成 Shiro

5.1 UserRealm.java

Spring Boot 根底就不介绍了，举荐下这个实战教程：
https://github.com/javastacks…

/**
 * 负责认证用户身份和对用户进行受权
 */
public class UserRealm extends AuthorizingRealm {

    @Autowired
    private UserService userService;

    @Autowired
    private RoleService roleService;

    @Autowired
    private PermissionService permissionService;

    // 用户受权
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {User user = (User) principalCollection.getPrimaryPrincipal();
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        List<Role> roleList = roleService.findRoleByUserId(user.getId());
        Set<String> roleSet = new HashSet<>();
        List<Integer> roleIds = new ArrayList<>();
        for (Role role : roleList) {roleSet.add(role.getRole());
            roleIds.add(role.getId());
        }
        // 放入角色信息
        authorizationInfo.setRoles(roleSet);
        // 放入权限信息
        List<String> permissionList = permissionService.findByRoleId(roleIds);
        authorizationInfo.setStringPermissions(new HashSet<>(permissionList));

        return authorizationInfo;
    }

    // 用户认证
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authToken) throws AuthenticationException {UsernamePasswordToken token = (UsernamePasswordToken) authToken;
        User user = userService.findByAccount(token.getUsername());
        if (user == null) {return null;}
        return new SimpleAuthenticationInfo(user, user.getPassword(), getName());
    }
}

5.2 ShiroConfig.java

@Configuration
public class ShiroConfig {

    @Bean
    public UserRealm userRealm() {return new UserRealm();
    }

    @Bean
    public DefaultWebSecurityManager securityManager() {DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(userRealm());
        return securityManager;
    }

    /**
     * 门路过滤规定
     * @return
     */
    @Bean
    public ShiroFilterFactoryBean shiroFilter(DefaultWebSecurityManager securityManager) {ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);

        shiroFilterFactoryBean.setLoginUrl("/login");
        shiroFilterFactoryBean.setSuccessUrl("/");
        Map<String, String> map = new LinkedHashMap<>();
        // 有先后顺序
        map.put("/login", "anon");      // 容许匿名拜访
        map.put("/**", "authc");        // 进行身份认证后能力拜访
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
        return shiroFilterFactoryBean;
    }

    /**
     * 开启 Shiro 注解模式，能够在 Controller 中的办法上增加注解
     * @param securityManager
     * @return
     */
    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(@Qualifier("securityManager") DefaultSecurityManager securityManager) {AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
        return authorizationAttributeSourceAdvisor;
    }

5.3 LoginController.java

@RestController
@RequestMapping("")
public class LoginController {@PostMapping("/login")
    public ServerResponseVO login(@RequestParam(value = "account") String account,
                                  @RequestParam(value = "password") String password) {Subject userSubject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(account, password);
        try {
            // 登录验证
            userSubject.login(token);
            return ServerResponseVO.success();} catch (UnknownAccountException e) {return ServerResponseVO.error(ServerResponseEnum.ACCOUNT_NOT_EXIST);
        } catch (DisabledAccountException e) {return ServerResponseVO.error(ServerResponseEnum.ACCOUNT_IS_DISABLED);
        } catch (IncorrectCredentialsException e) {return ServerResponseVO.error(ServerResponseEnum.INCORRECT_CREDENTIALS);
        } catch (Throwable e) {e.printStackTrace();
            return ServerResponseVO.error(ServerResponseEnum.ERROR);
        }
    }

    @GetMapping("/login")
    public ServerResponseVO login() {return ServerResponseVO.error(ServerResponseEnum.NOT_LOGIN_IN);
    }

    @GetMapping("/auth")
    public String auth() {return "已胜利登录";}

    @GetMapping("/role")
    @RequiresRoles("vip")
    public String role() {return "测试 Vip 角色";}

    @GetMapping("/permission")
    @RequiresPermissions(value = {"add", "update"}, logical = Logical.AND)
    public String permission() {return "测试 Add 和 Update 权限";}
}

6. 测试

6.1 用 root 用户登录

6.1.1 登录

6.1.2 验证是否登录

6.1.3 测试角色权限

6.1.4 测试用户操作权限

6.2 user 用户和 vip 用户测试略

7. 总结

本文演示了 SpringBoot 极简集成 Shiro 框架，实现了根底的身份认证和受权性能，如有有余，请多指教。

后续可扩大的性能点有：

  • 集成 Redis 实现 Shiro 的分布式会话
  • 集成 JWT 实现单点登录性能
