Spring Boot Data JPA无法在MockMVC测试中自动装配存储库接口

时间：2017-02-26 18:32:38

标签： java spring spring-boot spring-data-jpa

我正在使用Spring Data JPA和Spring Boot，并进行模拟MVC测试，结​​果是以下堆栈跟踪：

Parameter 1 of constructor in xyz.jacobclark.controllers.HomeController required a bean of type 'xyz.jacobclark.repositories.PageRepository' that could not be found.


Action:

Consider defining a bean of type 'xyz.jacobclark.repositories.PageRepository' in your configuration.

这是实际的存储库：

package xyz.jacobclark.repositories;

import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import xyz.jacobclark.models.entities.Page;

import java.util.List;

@Repository
public interface PageRepository extends CrudRepository<Page, String> {
    List<Page> findById(String id);

    List<Page> findByTitle(String titlex);
}

虽然控制器看起来像：

package xyz.jacobclark.controllers;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import xyz.jacobclark.adapters.GitHubAdapter;
import xyz.jacobclark.repositories.PageRepository;

import java.util.Map;
import java.util.concurrent.ExecutionException;

@Controller
public class HomeController {
    PageRepository pageRepository;
    private GitHubAdapter gitHubAdapter;

    @Autowired
    HomeController(GitHubAdapter gitHubAdapter, PageRepository pageRepository) {
        this.gitHubAdapter = gitHubAdapter;
        this.pageRepository = pageRepository;
    }

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Map<String, Object> model) throws ExecutionException {
        model.put("githubRepoCount", gitHubAdapter.getGitHubRepositoriesCount());
        return "home";
    }
}

最后，失败的测试：

package xyz.jacobclark.controllers;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import xyz.jacobclark.adapters.GitHubAdapter;

import static org.mockito.Mockito.when;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

@RunWith(SpringRunner.class)
@WebMvcTest(HomeController.class)
public class HomeControllerTest {

    @Autowired
    private MockMvc mvc;

    @MockBean
    private GitHubAdapter gitHubAdapter;

    @Test
    public void getOneRandomly() throws Exception {
        when(gitHubAdapter.getGitHubRepositoriesCount()).thenReturn("42");

        mvc.perform(get("/"))
                .andExpect(status().isOk())
                .andExpect(view().name("home"))
                .andExpect(model().attribute("githubRepoCount", "42"));
    }
}

答案 0 :(得分：1)

根据文档，注释 var checkOverlap = function (a, b) { if ( ((a.left < b.left && a.left + a.width > b.left) || (a.left > b.left && a.left + a.width < b.left + b.width) || (a.left > b.left && a.left + a.width > b.left + b.width)) && ((a.top < b.top && a.top + a.height > b.top) || (a.top > b.top && a.top + a.height > b.top) || (a.top > b.top && a.top < b.top + b.height)) && (a.left < b.left + b.width) && (a.top < b.top + b.height) ) { return true; } };会阻止与MVC测试无关的组件自动装配，这包括@WebMvcTest，这就是上述代码不起作用的原因。

错误说： No qualifying bean of type 'xyz.jacobclark.repositories.PageRepository'

您已模拟GitHubAdapter但未提供任何配置来实例化PageRepository。

我建议3个选项：

  1. 模拟PageRepository
  2. 提供@ContextConfiguration来实例化bean
  3. 如果null为ok，则将存储库标记为不需要：@Autowired(required = false)

答案 2 :(得分：0)

您的存储库。 

@Repository
public interface PageRepository extends CrudRepository<Page, String> {
    List<Page> findById(String id);

    List<Page> findByTitle(String titlex);
}

此@Repository（注释）将删除并移至您的Implements（实现）。 dao（界面） - ＆gt;该注释使用 DaoImpl 类（implements）。

示例entityManagerFactory 

<jpa:repositories base-package="xyz.jacobclark.repositories"></jpa:repositories>

样本库

不要使用Annotation（@Repository）。你在设置配置中使用base-package。

public interface AccountRepository extends PagingAndSortingRepository<Account, Integer>{

    public Account findById(String id);

    public List<Account> findByCompany(Company company);
}

您的控制器 

@Controller
public class HomeController {
    PageRepository pageRepository;
    private GitHubAdapter gitHubAdapter;

    @Autowired
    HomeController(GitHubAdapter gitHubAdapter, PageRepository pageRepository) {
        this.gitHubAdapter = gitHubAdapter;
        this.pageRepository = pageRepository;
    }

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Map<String, Object> model) throws ExecutionException {
        model.put("githubRepoCount", gitHubAdapter.getGitHubRepositoriesCount());
        return "home";
    }
}

样本控制器

您在控制器中使用服务和 dao 。控制器是门。所以实现只是bean。我认为你需要搜索DI和IOC。我建议不要使用你的模拟测试。你使用junit测试。你打电话给单位（服务和道）。此链接：this Spring Tutorial和this jUnit + Spring Tutorial XD。 

@RequestMapping(value = "/association")
@Controller
public class AssociationController {

    @Autowired
    private AssociationService associationService;

    @Autowired
    private AccountService accountService;

    @Autowired
    private CompanyService companyService;

    @Autowired
    private ProductService productService;

    @RequestMapping(value = "/settings/company")
    public ModelAndView showCompany(ModelAndView mav, HttpServletRequest req, Authentication auth) {
        CustomUserDetail customUserDetail = (CustomUserDetail) auth.getPrincipal();

        int associationIdx = customUserDetail.getAccount().getAssociation().getIdx();

        Association association = associationService.findAssociationByIdx(associationIdx);

        mav.addObject("association", association);
        mav.setViewName("/association/association_settings_company");

        return mav;
    }

    ....

}

答案 3 :(得分：0)

对我来说这是有效的：

  1. 对于任何需要模拟的 Spring-Data 存储库接口，请使用 @MockBean 。
  2. 对于任何 JPA 存储库实现类，都可以使用 @Mock（或其他标准方法）以标准方式模拟它们
  3. 单元测试 JPA+Spring-Data 可以在不使用内存数据库的情况下完成，所以不要假设您需要一个。
  4. 如果您的服务混合使用 Spring-Data 存储库接口和 JPA 实现的存储库类，则上述建议将有效。
  5. 我使用 @WebMvcTest 代替 @DataJpaTest 注释。并非每个人都需要使用 @WebMvcTest。
