问题：
此应用程序没有针对错误请求400的显式映射
晏经武
我有一个小的spring boot项目，效果很好。但是，我试图添加一些验证。。我在一个html页面上工作，但在另一个页面上失败了，没有可行的原因！
这是html页面（addProcedure.html）：
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">

对于控制器：
@PostMapping(value="/surgerywaitinglist/saveToWaitinList")
public String saveToWaitinList(@Valid WaitingList waitinglist, Surgeon surgeon, Department department , BindingResult result, Model model, @PathVariable Long patientId) {
System.out.println("in /surgerywaitinglist/saveToWaitinList");
System.out.println("result: "+ result);
boolean thereAreErrors = result.hasErrors();
if(thereAreErrors) {
//if(result.hasErrors()) {
return "addProcedure";
}
if(waitinglist.getWaitingListId()==null) {
System.out.println("saveToWaitinglist waitinglist: " + waitinglist);
Department tempDepartment = depRepo.findByDepartmentName(department.getDepartmentName());
Surgeon temSurgeon = surgeonRepo.findBySurgeonLastName(surgeon.getSurgeonLastName());
System.out.println("saveToWaitinglist tempSurgeon: " + temSurgeon);
System.out.println("saveToWaitinglist tempDepartment: " + tempDepartment);
waitinglist.setWaitingListSurgeonId(temSurgeon.getSurgeonId());
waitinglist.setWaitingListDepartmentId(tempDepartment.getDepartmentId());
waitinglist.setWaitingListPatientId(patientId);
waitingListRepo.save(waitinglist);
}
else {
System.out.println("saveToWaitinglist waitinglist else: " + waitinglist);
Department tempDepartment = depRepo.findByDepartmentName(department.getDepartmentName());
Surgeon temSurgeon = surgeonRepo.findBySurgeonLastName(surgeon.getSurgeonLastName());
waitinglist.setWaitingListActualBookingDate(waitinglist.getWaitingListActualBookingDate());
waitinglist.setWaitingListAdditionDate(waitinglist.getWaitingListAdditionDate());
waitinglist.setWaitingListProcedure(waitinglist.getWaitingListProcedure());
waitinglist.setWaitingListDiagnosis(waitinglist.getWaitingListDiagnosis());
waitinglist.setWaitingListSurgeonId(temSurgeon.getSurgeonId());
waitinglist.setWaitingListDepartmentId(tempDepartment.getDepartmentId());
waitinglist.setWaitingListPatientId(patientId);
waitingListRepo.save(waitinglist);
}
return "redirect:/surgerywaitinglist";
}
带有验证注释的实体类，，
package com.WaitingListThymeleaf.entity;
import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.format.annotation.DateTimeFormat.ISO;
import lombok.Data;
@Data
@Entity
@Table(name="waitingList")
public class WaitingList {
@Id
@GeneratedValue
private Long waitingListId;
@NotEmpty(message = "Please enter a procedure")
//@Size(min=5, max=30)
private String waitingListProcedure;
private String waitingListDiagnosis;
private Long waitingListPatientId;
private Long waitingListSurgeonId;
private Long waitingListDepartmentId;
@DateTimeFormat(iso=ISO.DATE)
private Date waitingListAdditionDate;
@DateTimeFormat(iso=ISO.DATE)
private Date waitingListActualBookingDate;
}
我试过@NotNull、@NotEmpty和@NotBlank，但运气不好。。。似乎验证有效。然而，我没有进入html页面！
相反，我得到了以下信息：
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

我重新安排了方法参数。。。。显然，BindingResult应该总是紧跟在需要验证的对象之后。。。
public String saveToWaitinList(@Valid WaitingList waitinglist, BindingResult result,
Surgeon surgeon, Department department,
Patient tempPatient, Model model) {

问题内容： 应用程序可以运行，但是出现错误： 我该如何解决？ 问题答案： 当我们创建一个Spring Boot应用程序时，我们用注解对其进行注解。该批注“包装”了许多其他必需的批注，以使应用程序正常工作。一种这样的注释是注释。该注释告诉Spring寻找Spring组件并配置要运行的应用程序。 你的应用程序类必须位于程序包层次结构的顶部，以便Spring可以扫描子程序包并找到其他必需的组件。 下面的
