无法找到@SpringBootConfiguration，您需要在测试中使用@ContextConfiguration或@SpringBootTest（classes = ...）

我正在使用Spring Data JPA和Spring Boot。应用程序的布局是这个

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

我的对象的存储库看起来像这样

public interface RelationalPlayerRepository extends JpaRepository<Player, Long> {
}

此外，对于存储库，我提供了配置

@Configuration
@EnableJpaRepositories(basePackages = "com.lapots.game.monolith.repository.relational")
@EntityScan("com.lapots.game.monolith.domain")
public class RelationalDBConfiguration {
}

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);
        };
    }
}

应用程序测试看起来像这样

@RunWith(SpringRunner.class)
@SpringBootTest
public class GrandJourneyMonolithApplicationTests {

    @Test
    public void contextLoads() {
    }

}

存储库的测试看起来像这样

@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;
    }
}

但是当我尝试运行测试时，我得到了错误

有什么问题？ 域名Player像这样徘徊

@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;
}

@SpringBootTest有一个名为classes的参数。它接受一组用于配置的类。向其添加配置文件的类，例如：

@SpringBootTest(classes={com.lapots.game.monolith.web.GrandJourneyMonolithApplication.class})

答案 1 :(得分：3)

当SpringBoot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。您的配置位于其他文件下，这是问题的原因。将你的配置上移到 monolith 包，一切都会好起来

答案 2 :(得分：1)

src/test/java软件包和src/main/java软件包应该匹配。 我遇到的一个问题是我的src/main/java软件包以 com.comp.example 开头，而src/test/java软件包以 com.sample.example 开头。 因此，春季启动应用程序无法提取其从@SpringBootApplication类中提取的应用程序的配置。 因此，测试用例应属于编写@SpringBootApplication中的src/main/java的程序包之内。

答案 3 :(得分：0)

我正在将Spring Boot与一个简单的REST控制器一起使用。没有使用任何JPA，并且出现了与我的控制器测试标题中指定的错误相同的错误。另外，我正在为Spring Boot应用程序使用自定义配置。 上面的第二个答案（于18年10月19日在Saurabh Parmar于7:20回答）有所帮助。对我来说，根本原因也是软件包名称。我在src / test / java下测试的软件包与src / main / java下的软件包不匹配。一旦我修复了它的作用。

答案 4 :(得分：0)

只有在@SpringBootTest 类中包含上下文配置类和应用程序类后，我才能解决此问题。

答案 5 :(得分：0)

在我的情况下，这是由于某些 [移动|复制/过去] 类。对于某些包子句[未正确更新|不存在|正确，但不知何故没有进行更改]。

无论如何，请检查您的项目打包。
