Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test
提问by lapots
I am using Spring Data JPAand Spring Boot. The layout of the application is this
我正在使用Spring Data JPA和Spring Boot。应用程序的布局是这样的
main
+-- java
+-- com/lapots/game/monolith
+-- repository/relational
+--RelationalPlayerRepository.java
+-- web
+--GrandJourneyMonolithApplication.java
+-- config
+-- RelationalDBConfiguration.java
test
+-- java
+-- com/lapots/game/monolith
+-- repository/relational
+-- RelationalPlayerRepositoryTests.java
+-- web
+-- GrandJourneyMonolithApplicationTests.java
The repository for my object looks like this
我的对象的存储库看起来像这样
public interface RelationalPlayerRepository extends JpaRepository<Player, Long> {
}
Additionally for the repositories I provided a configuration
另外对于存储库，我提供了一个配置
@Configuration
@EnableJpaRepositories(basePackages = "com.lapots.game.monolith.repository.relational")
@EntityScan("com.lapots.game.monolith.domain")
public class RelationalDBConfiguration {
}
My main application looks like this
我的主要应用程序看起来像这样
@SpringBootApplication
@ComponentScan("com.lapots.game.monolith")
public class GrandJourneyMonolithApplication {
@Autowired
private RelationalPlayerRepository relationalPlayerRepository;
public static void main(String[] args) {
SpringApplication.run(GrandJourneyMonolithApplication.class, args);
}
@Bean
public CommandLineRunner initPlayers() {
return (args) -> {
Player p = new Player();
p.setLevel(10);
p.setName("Master1909");
p.setClazz("warrior");
relationalPlayerRepository.save(p);
};
}
}
Test for application looks like this
应用程序测试看起来像这样
@RunWith(SpringRunner.class)
@SpringBootTest
public class GrandJourneyMonolithApplicationTests {
@Test
public void contextLoads() {
}
}
The test for repository looks like this
存储库的测试如下所示
@RunWith(SpringRunner.class)
@DataJpaTest
public class RelationalPlayerRepositoryTests {
@Autowired
private TestEntityManager entityManager;
@Autowired
private RelationalPlayerRepository repository;
@Test
public void testBasic() {
Player expected = createPlayer("Master12", "warrior", 10);
this.entityManager.persist(expected);
List<Player> players = repository.findAll();
assertThat(repository.findAll()).isNotEmpty();
assertEquals(expected, players.get(0));
}
private Player createPlayer(String name, String clazz, int level) {
Player p = new Player();
p.setId(1L);
p.setName(name);
p.setClazz(clazz);
p.setLevel(level);
return p;
}
}
But when I try to run the tests I get the error
但是当我尝试运行测试时出现错误
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.041 sec <<< FAILURE! - in com.lapots.game.monolith.repository.relational.RelationalPlayerRepositoryTests

What is the problem?
Domain Playerloooks like this
问题是什么？域Player看起来像这样
@Data
@Entity
@Table(schema = "app", name = "players")
public class Player {
@Id
@GeneratedValue
private Long id;
@Transient
Set<Player> comrades;
@Column(unique = true)
private String name;
private int level;
@Column(name = "class")
private String clazz;
}

When the SpringBoot starts it scans classpath from the top to the bottom of the project to find the config file. Your config is under another files and that is a reason of the problem. Move you config upper to the monolithpackage and everything gonna be fine
当 SpringBoot 启动时，它会从项目的顶部到底部扫描类路径以找到配置文件。您的配置在另一个文件下，这就是问题的原因。将你的配置移到整体包上，一切都会好起来的

src/test/javapackages and src/main/javapackages should match.
I had same issue where my src/main/javapackages were starting with com.comp.examplebut src/test/javapackages were starting with com.sample.example.
Because of this spring boot application was not able to pickup the configuration of the application which it picks up from @SpringBootApplicationclass.
So test case should fall under the packages where @SpringBootApplicationin src/main/javais written.
src/test/java包和src/main/java包应该匹配。我有同样的问题，我的src/main/java包以com.comp.example开头，但src/test/java包以com.sample.example开头。由于这个 spring boot 应用程序无法获取它从@SpringBootApplication类中获取的应用程序的配置。所以测试用例应该属于写@SpringBootApplicationin的包src/main/java。

I am using Spring Boot with a simple REST controller. Not using any JPA and was getting same error as specified in the title here for my controller test. Also I am using a custom configuration for my Spring boot app. The 2nd answer above (answered Oct 19 '18 at 7:20 Saurabh Parmar) helped. The root cause for me too was the package name. The package for my test under the src/test/java was not matching the one under the src/main/java. Once I fixed that it worked.
我正在使用带有简单 REST 控制器的 Spring Boot。没有使用任何 JPA，并且在我的控制器测试中遇到与标题中指定的相同的错误。此外，我正在为我的 Spring Boot 应用程序使用自定义配置。上面的第二个答案（Saurabh Parmar 于 18 年 10 月 19 日 7:20 回答）有所帮助。我的根本原因也是包名称。我在 src/test/java 下的测试包与 src/main/java 下的包不匹配。一旦我确定它起作用了。
