SpringBoot获取Json格式请求报错com.fasterxml.jackson.databind.JavaType.isReferenceType()Z

如果pom文件中存在此依赖，将其注释掉

Cotroller代码

@Controller
@RequestMapping(value = "/ML")
public class MLModelCtronller {

    @RequestMapping(value = "/getPredic",produces = "application/json;charset=UTF-8",method = RequestMethod.POST)
    @ResponseBody
    public Object getPredict(@RequestBody Device device) {

        
        String a = device.getDay();
        String b = device.getTemperature();
        String c = device.getFlowSpeed();
        String d = device.getWaterPressure();

        if ((isValidateNumbers(a) && isValidateNumbers(b) && isValidateNumbers(c) && isValidateNumbers(d))) {
         
            return 12.2;
        }
        return null;

    }

然后使用PostMan测试
