Java获取时间，自动给创建时间创建人等赋值

 @ApiOperation("添加")
    @PostMapping()
    public ApiResult<?> save(@RequestBody FeePropertyRoomArea feePropertyRoomArea) {
        User user=getLoginUser();
        LocalDateTime localDateTime = LocalDateTime.now();
        feePropertyRoomArea.setCreateTime(localDateTime);
        feePropertyRoomArea.setCreUserId(Long.valueOf(user.getUserId()));
        feePropertyRoomArea.setCreUserName(user.getUsername());
        if (feePropertyRoomAreaService.save(feePropertyRoomArea)) {
            return success("添加成功");
        }
        return fail("添加失败");
    }

    @ApiOperation("修改")
    @PutMapping()
    public ApiResult<?> update(@RequestBody FeePropertyRoomArea feePropertyRoomArea) {
        User user=getLoginUser();
        LocalDateTime localDateTime = LocalDateTime.now();
        feePropertyRoomArea.setUpdateTime(localDateTime);
        feePropertyRoomArea.setUpdUserId(Long.valueOf(user.getUserId()));
        feePropertyRoomArea.setUpdUserName(user.getUsername());
        if (feePropertyRoomAreaService.updateById(feePropertyRoomArea)) {
            return success("修改成功");
        }
        return fail("修改失败");
    }
