无法找到@SpringBootConfiguration，您需要在测试中使用@ContextConfiguration 或@SpringBootTest(类=...)
Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test
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
我的对象的存储库如下所示
public interface RelationalPlayerRepository extends JpaRepository<Player, Long> {
}
此外，我还为存储库提供了一个配置
@Configuration
@EnableJpaRepositories(basePackages = "com.lapots.game.monolith.repository.relational")
@EntityScan("com.lapots.game.monolith.domain")
public class RelationalDBConfiguration {
}
我的主应用程序如下所示
@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);
};
}
}
应用程序测试如下所示
@RunWith(SpringRunner.class)
@SpringBootTest
public class GrandJourneyMonolithApplicationTests {
@Test
public void contextLoads() {
}
}
存储库测试如下所示
@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;
}
}

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;
}
当Spring Boot 启动时，它会从项目的顶部到底部扫描类路径以查找配置文件。您的配置在另一个文件下，这是问题的原因。将您的配置移至 monolith 包，一切都会好起来的。
src/test/java 包和 src/main/java 包应该匹配。
我遇到了同样的问题
- 我的
src/main/java 包以 com.comp.example 开头，但是
src/test/java 软件包以 com.sample.example
因此 spring 引导应用程序无法获取应用程序的配置，它是从 @SpringBootApplication class 获取的。
所以测试用例应该属于 @SpringBootApplication in src/main/java 中写入的相同包。
@SpringBootTest 有一个名为 classes 的参数。它接受一组 classes 进行配置。将配置文件的 class 添加到其中，例如：
@SpringBootTest(classes={com.lapots.game.monolith.web.GrandJourneyMonolithApplication.class})
只有在将上下文配置 class 和应用程序 class.
都包含在 @SpringBootTest classes 中后，我才能够解决这个问题。
在我的案例中，这是由于 类 的一些 [移动|copy/paste]。对于某些人来说，package 子句要么是 [未正确更新|不存在] 并且未提取更改，但 IDE.
无论如何，请检查您的项目打包。
删除文件module-info.java。这对我有用。
测试 src/test/java 文件也应遵循与 src/main/java.
