Question

我正在使用spring mvc测试框架进行单元测试。

以下是我的源代码： com.exmple.main

MyController.java

@Controller
public class MyController {

    @Autowired
    private MyService myService;

    @RequestMapping(method = RequestMethod.POST)
    @ResponseBody
    public Map<Object, Object> myControllerFunction(@RequestBody final Object jsonRequest) {
        /* do something */

        return response;
    }
}

MyRepository.java

@Repository
public interface MyRepository extends JpaRepository<My, String> {

    @Query(value="select * from my d where (d.start_date<to_date(:date,'YYYY/DD/MM')) and (d.end_date>to_date(:date,'YYYY/DD/MM'))", nativeQuery=true)
    List<My> findByDate(@Param("date") String date);
}

MyService.java

public interface MyService {
    List<My> findByDate(String date);
}

MyServiceImpl.java

@Service

public class MyServiceImpl implements MyService {
    @Autowired
    MyRepository destRepo;

    @Override
    public List<My> findByDate(String date) {
        List<My> listDest = destRepo.findByDate(date);

        return listDest;
    }
}

com.example.test

MyControllerTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes={TestConfig.class})
@WebAppConfiguration
public class MyControllerTest {
    private MockMvc mockMvc;

    @Autowired
    MyService myService;

    @Autowired
    protected WebApplicationContext webApplicationContext;

    @Before
    public void setup() throws Exception {
        // this.mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void listAllMy() throws Exception {

    }
}

TestConfig.java

@Configuration
public class TestConfig {
    @Bean
    public MyService myService() {
        // set properties, etc.
        return new MyServiceImpl();
    }
}

运行测试时，会显示以下错误嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException

我知道发生了异常，因为MyService没有找到任何MyRepository bean。但我不知道如何创建一个存储库bean。请教我如何使用Java（而不是xml）创建存储库类的bean。

您需要在配置类中启用JPA存储库，指定包含存储库的包，如下所示

@Configuration
@EnableJpaRepositories(basePackages = {
    "com.example.repository"
})
public class TestConfig {
    @Bean
    public MyService myService() {
        // set properties, etc.
        return new DestinationServiceImpl();
    }
}

编辑：看起来你还没有定义entityManager和dataSource。请参阅a tutorial here并回答类似问题here
