                               String last, String email, String passwd ) {
            // 使用newUser方法创建User实例
            User user = identityService.newUser(id);
            // 设置用户的各个属性
            user.setFirstName(first);
            user.setLastName(last);
            user.setEmail(email);
            user.setPassword(passwd);
            // 使用saveUser方法保存用户
            identityService.saveUser(user);
            return identityService.createUserQuery().userId(id).singleResult();
        }
    }

**二 运行结果**

经理组的候选任务有：
       申请假期
    张三的候选任务有
       审批假期
    经理组与员工组的任务有：
       申请假期
       审批假期
    关系数据量: 2
