java - 参数值 [1] 与预期类型不匹配

Question

在 Spring-boot 项目中，我尝试将 Date 对象作为请求参数传递，并收到此错误:

Parameter value [1] did not match expected type [java.util.Date (n/a)]

这是我发送的http请求:

http://localhost:8080/moneyManager/customer/actionBetweenDates?startDate=2019/07/01&endDate=2019/07/30

这是其余部分触发的功能:

@RequestMapping(path="actionBetweenDates", method=RequestMethod.GET)
public Collection<Action> getActionByDate(@RequestParam Date startDate, @RequestParam Date endDate){
    return customerService.getAllActionBetweenDate(getSession().getId(), startDate, endDate);
}

休息中的函数触发服务中的函数:

public Collection<Action> getAllActionBetweenDate(long customerId, Date startDate, Date endDate) {
        Collection<MethodPayment> customerMethodPayments = methodPaymentRepository.findByCustomerId(customerId);
        Collection<Action> customerActionByDates = new ArrayList<>();
        for (MethodPayment mp : customerMethodPayments) {
            customerActionByDates
                    .addAll(actionRepository.findByDateBetweenAndMethodPaymentId(mp.getId(), startDate, endDate));
        }
        return customerActionByDates;
    }

服务中的函数触发存储库中的函数:

Collection<Action> findByDateBetweenAndMethodPaymentId(long methodPaymentId, Date startDate, Date endDate);

我做错了什么？

更新:

我发现了问题。 该问题与 actionRepository 中找到的函数有关。 该函数的签名首先要求两个日期进行比较，然后 id 和我给它相反的值。 我很清楚，在我上了它之后，我会对日期产生疑问，所以答案确实对我有帮助。 谢谢大家!

Answer 1

将 Controller 方法更改为:

@RequestMapping(path="actionBetweenDates", method=RequestMethod.GET)
public Collection<Action> getActionByDate(@RequestParam @DateTimeFormat(pattern = "yyyy/MM/dd") Date startDate, @RequestParam @DateTimeFormat(pattern = "yyyy/MM/dd") Date endDate){
    return customerService.getAllActionBetweenDate(getSession().getId(), startDate, endDate);
}

检查Annotation Type DateTimeFormat有关详细信息，有关用法示例，请查看 Working with Date Parameters in Spring

UPD 1:
添加示例 @SpringBootApplication 类和示例请求:

@SpringBootApplication
@RestController
public class DateProblemApp {

    public static void main(String[] args) {
        SpringApplication.run(DateProblemApp.class, args);
    }

    @RequestMapping(path="actionBetweenDates", method = RequestMethod.GET)
    public String getActionByDate(@RequestParam @DateTimeFormat(pattern = "yyyy/MM/dd") Date startDate, @RequestParam @DateTimeFormat(pattern = "yyyy/MM/dd") Date endDate) {
        return "ok";
    }

}

示例请求:http://localhost:8080/actionBetweenDates?startDate=2019/07/01&endDate=2019/07/30
