• 七.測試

---

一.說明

SpringSecurity是一個用於Java 企業級應用程序的安全框架,主要包含用戶認證和用戶受權兩個方面.相比較Shiro而言,Security功能更加的強大,它能夠很容易地擴展以知足更多安全控制方面的需求,但也相對它的學習成本會更高,兩種框架各有利弊.實際開發中仍是要根據業務和項目的需求來決定使用哪種.

JWT是在Web應用中安全傳遞信息的規範,從本質上來講是Token的演變,是一種生成加密用戶身份信息的Token,特別適用於分佈式單點登錄的場景,無需在服務端保存用戶的認證信息,而是直接對Token進行校驗獲取用戶信息,使單點登陸更爲簡單靈活.

二.項目環境

• SpringBoot版本:2.1.6
• SpringSecurity版本: 5.1.5
• MyBatis-Plus版本: 3.1.0
• JDK版本:1.8
• 數據表(SQL文件在項目中):數據庫中測試號的密碼進行了加密,密碼皆爲123456

                            }
                        }
                    }
                    //組裝參數
                    SelfUserEntity selfUserEntity = new SelfUserEntity();
                    selfUserEntity.setUsername(claims.getSubject());
                    selfUserEntity.setUserId(Long.parseLong(claims.getId()));
                    selfUserEntity.setAuthorities(authorities);
                    UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(selfUserEntity, userId, authorities);
                    SecurityContextHolder.getContext().setAuthentication(authentication);
                }
            } catch (ExpiredJwtException e){
                log.info("Token過時");
            } catch (Exception e) {
                log.info("Token無效");
            }
        }
        filterChain.doFilter(request, response);
        return;
    }
}

六.權限註解和hasPermission權限擴展

Security容許咱們在定義URL方法訪問所應有的註解權限時使用SpringEL表達式,在定義所需的訪問權限時若是對應的表達式返回結果爲true則表示擁有對應的權限,反之則沒有權限,會進入到咱們配置的UserAuthAccessDeniedHandler(暫無權限處理類)中進行處理.這裏舉一些例子,代碼中註釋有對應的描述.

圖片

/**
     * 管理端信息
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回數據MAP
     */
    @PreAuthorize("hasRole('ADMIN')")
    @RequestMapping(value = "/info",method = RequestMethod.GET)
    public Map<String,Object> userLogin(){
        Map<String,Object> result = new HashMap<>();
        SelfUserEntity userDetails = SecurityUtil.getUserInfo();
        result.put("title","管理端信息");
        result.put("data",userDetails);
        return ResultUtil.resultSuccess(result);
    }
    /**
     * 擁有ADMIN或者USER角色能夠訪問
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回數據MAP
     */
    @PreAuthorize("hasAnyRole('ADMIN','USER')")
    @RequestMapping(value = "/list",method = RequestMethod.GET)
    public Map<String,Object> list(){
        Map<String,Object> result = new HashMap<>();
        List<SysUserEntity> sysUserEntityList = sysUserService.list();
        result.put("title","擁有用戶或者管理員角色均可以查看");
        result.put("data",sysUserEntityList);
        return ResultUtil.resultSuccess(result);
    }
    /**
     * 擁有ADMIN和USER角色能夠訪問
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回數據MAP
     */
    @PreAuthorize("hasRole('ADMIN') and hasRole('USER')")
    @RequestMapping(value = "/menuList",method = RequestMethod.GET)
    public Map<String,Object> menuList(){
        Map<String,Object> result = new HashMap<>();
        List<SysMenuEntity> sysMenuEntityList = sysMenuService.list();
        result.put("title","擁有用戶和管理員角色均可以查看");
        result.put("data",sysMenuEntityList);
        return ResultUtil.resultSuccess(result);
    }

一般狀況下使用hasRole和hasAnyRole基本能夠知足大部分鑑權需求,可是有時候面對更復雜的場景上述常規表示式沒法完成權限認證,Security也爲咱們提供瞭解決方案.經過hasPermission()來擴展表達式.使用hasPermission()首先要實現PermissionEvaluator接口

/**
 * 自定義權限註解驗證
 * @Author Sans
 * @CreateTime 2019/10/6 13:31
 */
@Component
public class UserPermissionEvaluator implements PermissionEvaluator {
    @Autowired
    private SysUserService sysUserService;
    /**
     * hasPermission鑑權方法
     * 這裏僅僅判斷PreAuthorize註解中的權限表達式
     * 實際中能夠根據業務需求設計數據庫經過targetUrl和permission作更復雜鑑權
     * 固然targetUrl不必定是URL能夠是數據Id還能夠是管理員標識等,這裏根據需求自行設計
     * @Author Sans
     * @CreateTime 2019/10/6 18:25
     * @Param  authentication  用戶身份(在使用hasPermission表達式時Authentication參數默認會自動帶上)
     * @Param  targetUrl  請求路徑
     * @Param  permission 請求路徑權限
     * @Return boolean 是否經過
     */
    @Override
    public boolean hasPermission(Authentication authentication, Object targetUrl, Object permission) {
        // 獲取用戶信息
        SelfUserEntity selfUserEntity =(SelfUserEntity) authentication.getPrincipal();
        // 查詢用戶權限(這裏能夠將權限放入緩存中提高效率)
        Set<String> permissions = new HashSet<>();
        List<SysMenuEntity> sysMenuEntityList = sysUserService.selectSysMenuByUserId(selfUserEntity.getUserId());
        for (SysMenuEntity sysMenuEntity:sysMenuEntityList) {
            permissions.add(sysMenuEntity.getPermission());
        }
        // 權限對比
        if (permissions.contains(permission.toString())){
            return true;
        }
        return false;
    }
    @Override
    public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission) {
        return false;
    }
}

在請求方法上添加hasPermission示例

/**
     * 擁有sys:user:info權限能夠訪問
     * hasPermission 第一個參數是請求路徑 第二個參數是權限表達式
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回數據MAP
     */
    @PreAuthorize("hasPermission('/admin/userList','sys:user:info')")
    @RequestMapping(value = "/userList",method = RequestMethod.GET)
    public Map<String,Object> userList(){
        Map<String,Object> result = new HashMap<>();
        List<SysUserEntity> sysUserEntityList = sysUserService.list();
        result.put("title","擁有sys:user:info權限均可以查看");
        result.put("data",sysUserEntityList);
        return ResultUtil.resultSuccess(result);
    }

hasPermission能夠也能夠和其餘表達式聯合使用

/**
     * 擁有ADMIN角色和sys:role:info權限能夠訪問
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回數據MAP
     */
    @PreAuthorize("hasRole('ADMIN') and hasPermission('/admin/adminRoleList','sys:role:info')")
    @RequestMapping(value = "/adminRoleList",method = RequestMethod.GET)
    public Map<String,Object> adminRoleList(){
        Map<String,Object> result = new HashMap<>();
        List<SysRoleEntity> sysRoleEntityList = sysRoleService.list();
        result.put("title","擁有ADMIN角色和sys:role:info權限能夠訪問");
        result.put("data",sysRoleEntityList);
        return ResultUtil.resultSuccess(result);
    }

七.測試

建立帳戶這裏用戶加密使用了Security推薦的bCryptPasswordEncoder方法

/**
     * 註冊用戶
     */
    @Test
    public void contextLoads() {
        // 註冊用戶
        SysUserEntity sysUserEntity = new SysUserEntity();
        sysUserEntity.setUsername("sans");
        sysUserEntity.setPassword(bCryptPasswordEncoder.encode("123456"));
        // 設置用戶狀態
        sysUserEntity.setStatus("NORMAL");
        sysUserService.save(sysUserEntity);
        // 分配角色 1:ADMIN 2:USER
        SysUserRoleEntity sysUserRoleEntity = new SysUserRoleEntity();
        sysUserRoleEntity.setRoleId(2L);
        sysUserRoleEntity.setUserId(sysUserEntity.getUserId());
        sysUserRoleService.save(sysUserRoleEntity);
    }

登陸USER角色帳號,登陸成功後咱們會獲取到身份認證的Token

圖片

訪問USER角色的接口,把上一步獲取到的Token設置在Headers中,Key爲Authorization,咱們以前實現的JWTAuthenticationTokenFilter攔截器會根據請求頭中的Authorization獲取並解析Token

圖片

使用USER角色Token訪問ADMIN角色的接口,會被拒絕,告知未受權(暫無權限會進入咱們定義的UserAuthAccessDeniedHandler這個類進行處理)

圖片

更換ADMIN角色進行登陸並訪問ADMIN接口
