Springboot之表单验证

实体类

@TableName("lh_admin")
public class Admin extends Model<Admin> {

    private static final long serialVersionUID = 1L;

    /**
     * 管理员ID
     */
	@TableId(value="admin_id", type= IdType.AUTO)
	private Integer adminId;
    /**
     * 用户名
     */
    @NotEmpty(message="用户姓名不能为空")
    @Size(min = 2, max = 4, message = "用户长度要大于2，小于4")
	@TableField("admin_user")
	private String adminUser;
    /**
     * 密码
     */
	@NotNull(message = "密码不能为空")
	@TableField("admin_password")
	private String adminPassword;
    /**
     * 创建时间
     */
	@TableField("admin_create_time")
	private Date adminCreateTime;
    /**
     * 是否被锁定 0 未锁定 1 锁定
     */
	@TableField("admin_locked")
	private String adminLocked;
    /**
     * 最新登录时间
     */
	@TableField("admin_update_time")
	private Date adminUpdateTime;
    /**
     * 创建者ID
     */
	@TableField("admin_create_user_id")
	private Integer adminCreateUserId;
    /**
     * 手机号
     */
	@Size(min = 11, max = 11, message = "手机号格式不对")
	@TableField("admin_phone")
	private String adminPhone;
    /**
     * 邮箱
     */
	@TableField("admin_email")
	private String adminEmail;
    /**
     * 加密盐值
     */
	@TableField("admin_salt")
	private String adminSalt;
    
    /* 省略get、set方法和构造函数(默认构造、所有属性的构造函数) */
}

Mapper层方法

@Mapper
public interface AdminMapper extends BaseMapper<Admin> {

}

Servcie层

public interface AdminService extends IService<Admin> {
	
}

Service实现类

@Service
public class AdminServiceImpl extends ServiceImpl<AdminMapper, Admin> implements AdminService {
    
}

控制器层

@Controller
@RequestMapping("/admin")
public class UserController {
    
    private final static Logger logger = LoggerFactory.getLogger(UserController.class);

    @Autowired
    private AdminService adminService;
    
    @PostMapping("/author/user/submit_add")
    @ResponseBody
    public JsonResult adminSubmit(@Valid Admin admin, BindingResult result, HttpSession session){
        // 这个要注意不能使用 result.hasErrors(),是无法回数据的，不走if判断。
        if (result.hasFieldErrors()) {
            // JsonResult 是一个接口数据的封装类
            return new JsonResult(ResultCode.FAIL, result.getFieldError().getDefaultMessage());
        }else{
            Admin session_admin = (Admin) session.getAttribute("admin");
            admin.setAdminCreateTime(new Date());
            admin.setAdminUpdateTime(new Date());
            admin.setAdminCreateUserId(session_admin.getAdminId());
            logger.info("增加的用户信息+"+admin);
            adminService.insert(admin);
            return new JsonResult();
        }
    }
}
