【问题描述】：

我正在尝试使用 REST API 创建一个基本的 Spring Boot 应用程序 (JDK 1.8)。以下是我的应用代码

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

    @SpringBootApplication
    public class OrderApplication 

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

我添加了一个控制器如下

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
@RequestMapping("/api")
public class OrderRestController 

    private OrderService orderService;


    //injecting order service use constructor injection
    @Autowired
    public OrderRestController(OrderService theCarService) 
        orderService=theCarService;
    


    //expose "/orders" and return the list of orders.
    @GetMapping("/orders")
    public List<Order> findAll()
        return orderService.findAll();
    

测试代码是：

import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;

import com.fasterxml.jackson.databind.ObjectMapper;

@RunWith(SpringRunner.class)
@WebMvcTest(OrderRestController.class)
@AutoConfigureMockMvc
public class OrderRestControllerTest 

  @Autowired
  private MockMvc mvc;

  @MockBean
  private OrderService service;

  @Test
  public void getAllOrdersAPI() throws Exception
  
    mvc.perform( MockMvcRequestBuilders
        .get("/orders")
        .accept(MediaType.APPLICATION_JSON))
        .andExpect(status().isOk())
        .andExpect(MockMvcResultMatchers.jsonPath("$.orders").exists())
        .andExpect(MockMvcResultMatchers.jsonPath("$.orders[*].orderId").isNotEmpty());
  

服务实现：

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


@Service
public class OrderServiceImpl implements OrderService 

    private OrderDAO orderDao;

    //injecting order dao use constructor injection
    @Autowired
    public OrderServiceImpl(OrderDAO theOrderDao) 
        orderDao=theOrderDao;
    

    @Override
    public List<Order> findAll() 
        return orderDao.findAll();
    

当我运行这个应用程序时，它会成功启动，而且我还可以看到我填充的模拟数据。

控制台日志

    HTTP Method = GET
      Request URI = /orders
       Parameters = 
          Headers = [Accept:"application/json"]
             Body = <no character encoding set>
    Session Attrs =

任何人都可以帮助我吗？非常感谢！

谢谢

【参考方案1】：

我可以看到 2 个问题：

可能，您的意思是：

MockMvcRequestBuilders.get("/api/orders")

为了断言控制器返回某些内容，您应该对service 进行存根调用：

@Test
public void getAllOrdersAPI() throws Exception 
   Order order = create expected order object
   when(service.findAll()).thenReturn(Arrays.asList(order));
   // rest of the test

【讨论】：

谢谢，我实现了 1.one，但是当我执行第二个时，由于 when 和 thenReturn 方法，它会出现编译错误。

@UğurTaşkan 来自 Mockito，所以只需添加 import static org.mockito.Mockito.*;

再次感谢，现在更好了:) 响应状态更改为 401 并且我已经实现了基本安全性，正因为如此。有什么方法可以禁用此测试的安全性？

@UğurTaşkan 尝试用 @EnableAutoConfiguration(exclude = SecurityAutoConfiguration.class, ManagementSecurityAutoConfiguration.class ) 注释 OrderRestControllerTest 类

@UğurTaşkan 如果上述方法不起作用 - 请尝试 @AutoConfigureMockMvc(secure = false)

【参考方案2】：

你的测试应该是这样的

@Test
  public void getAllOrdersAPI() throws Exception
  
    mvc.perform( MockMvcRequestBuilders
        .get("/api/orders")
        .accept(MediaType.APPLICATION_JSON))
        .andExpect(status().isOk())
        .andExpect(MockMvcResultMatchers.jsonPath("$.orders").exists())
        .andExpect(MockMvcResultMatchers.jsonPath("$.orders[*].orderId").isNotEmpty());
  

您错过了在获取 URL 中添加 /api。我没有看到其他任何东西。让我知道它是否有帮助，否则我会在我的机器上为你编译它。

你的 mockResponse 是 404。
