给自己提个醒

常用注解

@RequestParam(value = "name") String string 和 @RequestParam String name是一样的，value标注了接受的key值，如果不标注就自动使用变量的名称

@Slf4j
@RestController
@RequestMapping("/t-booking")
public class TBookingController {
    @Autowired
    TBookingService tBookingService;
    // 所有预约记录
    @GetMapping(value = "/bookingList")
    public AjaxResponse bookingList(@RequestParam(value = "name") String string) {
        log.info("article:" + string);
        return AjaxResponse.success(string);
    }
}

@RequestBody
使用这个必须要用post格式，要创建一个vo，vo里面必须要有@Data注解

使用的时候是这个样子，要使用PostMapping，对象的属性对应着
