后台

MySql 函数
select YEAR(CURRENT_TIMESTAMP());
SELECT CURRENT_TIMESTAMP();
SELECT NOW()

判断为空
	Boolean validateNull(Object object){
		if (ObjUtil.isNull(object)) return true;
		if (StrUtil.isBlank(String.valueOf(object))) return true;
		return false;
	}

Wrapper in写法
        String[] billBusyState = {"已入库", "已出库", "已移库", "已盘点"};
        queryWrapper.in("b.bill_busy_state", billBusyState);

取guid
IdUtil.simpleUUID()

R回接
   private final CustomSqlService customSqlService;

    @Autowired
    private CustomerInfoUserService customerInfoUserService;
        CustomerInfo customerInfo = (CustomerInfo) customerInfoUserService.getByUserId(sysUser.getId().toString()).getData();
