嘿，我在创建测试用例时开始使用 spring boot 测试框架学习 spring-boot junit 测试，我面临以下问题。

如何解决这个问题。

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test
    at org.springframework.util.Assert.state(Assert.java:70)
    at org.springframework.boot.test.context.SpringBootTestContextBootstrapper.getOrFindConfigurationClasses(SpringBootTestContextBootstrapper.java:202)

    at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildDefaultMergedContextConfiguration(AbstractTestContextBootstrapper.java:323)

这是我的 RentalCarSystemApplicationTests.java

package com.test.project.rentalcarsystem;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RentalCarSystemApplicationTests {

       @Test
       public void contextLoads()
       {

       }
}

这是我的 TestWebApp.java

package com.test.project.rentalcarsystem;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.springframework.web.context.WebApplicationContext;
import org.junit.Before;
import …

发生异常时如何显示相应的错误信息。

假设在 GET 方法期间，如果未找到数据，则应显示自定义异常消息。

同样，如果我们试图删除不可用的数据。

Car.java

package com.car_rental_project.car_project;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity

public class Car {

    @Id
    private String id;
    private String modelname;
    private String type;
    private String year_of_registration;
    private String seating_capacity;
    private String cost_per_day;
    private String milleage;
    private String pincode;
    private String contact_number;
    private String email;

    public Car() {

    }

    public Car(String id, String modelname, String type, String year_of_registration, String seating_capacity,String cost_per_day, String milleage, String pincode, String contact_number, String email) {
        super();
        this.id = id;
        this.modelname = modelname; …

如何使用 PrimeNG 执行 On-click 事件。

当我们单击 New 菜单栏以获取 UserFormComponent.html 页面以添加新用户时。使用 PrimeNG 我们如何执行此操作。

我的代码可在：https: //stackblitz.com/edit/angular-rlf3nz appcomponent.html

<p-menubar [model]="items">

应用组件.ts

export class AppComponent {
  private user = new User();  //Newly added  
  constructor(private _userService:UserService) { }  //Newly added

  title = 'clientApp';
  private items: MenuItem[];

  ngOnInit() {
    this.items = [
    {
      label: 'Quotes',
      items: [
        { label: 'New ', icon: 'fa fa-refresh',  command: () => this.addNewUser()},
        { label: 'Show All', icon: 'fa fa-repeat', url: '#' }             
      ]
    }

   addNewUser(){
      this.user=this._userService.getter();
   } 

}

这是我的 …
