在没有 Spring Boot Application 主类的项目中测试 Spring Data Repository [英] Test Spring Data Repository in a project without a Spring Boot Application main class

问题描述

我有一个不包含运行 Spring Boot 应用程序的类的小项目.在那个类中，我只有一些配置和一些存储库.我想在小项目中测试这些存储库.

I have a small project that does not contain a class to run a Spring Boot Application. In that class I only have some configuration and some repositories. I would like to test those repositories inside the small project.

为此，我有以下几点:

@SpringBootTest
@DataJpaTest
public class TaskRepositoryTest extends AbstractTestNGSpringContextTests {

    @Autowired
    private TaskRepository taskRepository;

    @Test
    public void test() {
        taskRepository.save(new Task("open"));
    }
}

但我收到以下错误

Caused by: java.lang.NoSuchMethodError: org.springframework.boot.jdbc.DataSourceBuilder.findType(Ljava/lang/ClassLoader;)Ljava/lang/Class;

知道我必须做什么吗?

推荐答案

这适用于 Spring Boot 2.0.3、H2 和最新的 RELEASE testng:

This works for me with Spring Boot 2.0.3, H2 and latest RELEASE testng:

@EnableAutoConfiguration
@ContextConfiguration(classes = TaskRepository.class)
@DataJpaTest
public class TaskTest extends AbstractTestNGSpringContextTests {

   @Autowired
   private TaskRepository taskRepository;

   @Test
   public void test() {
      taskRepository.save(new Task("open"));
   }

}

LE:

在以前版本的答案中，我使用了 @SpringBootTest @DataJpaTest 但这似乎是错误的方法.将出现以下消息:

In the previous version of the answer I've used @SpringBootTest @DataJpaTest but that seems to be the wrong way to do it. The following message would appear:

[main] INFO org.springframework.boot.test.context.SpringBootTestContextBootstrapper - 没有为测试类 [one.adf.springwithoutapp.TaskTest] 找到 @ContextConfiguration 和 @ContextHierarchy，使用 SpringBootContextLoader

[main] INFO org.springframework.boot.test.context.SpringBootTestContextBootstrapper - Neither @ContextConfiguration nor @ContextHierarchy found for test class [one.adf.springwithoutapp.TaskTest], using SpringBootContextLoader

将 @ContextConfiguration 与 @DataJpaTest 一起使用可消除该警告，并且 IntelliJ 不会将模拟的 taskRepository 标记为 无法自动装配.未找到TaskRepository"类型的 bean.

Using @ContextConfiguration with @DataJpaTest removes that warning and IntelliJ doesn't mark the mocked taskRepository as Could not autowire. No beans of 'TaskRepository' type found.
