升级到2.2.0后，@ DataJpaTest和@WebMvcTest停止工作

Question

将Spring Boot从2.1.8升级到2.2.0后，未加载完整应用程序上下文的测试开始失败。

@DataJpaTest
@TestPropertySource(properties = "spring.jpa.hibernate.ddl-auto=none")
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
public class MyRepositoryTest {

    @Autowired private TestEntityManager entityManager;
    @Autowired private MyRepository repository;

    @Test
    public void test() {
    ....
    }

这会产生以下错误

20:44:35.866 [main] [ERROR] o.s.b.d.LoggingFailureAnalysisReporter -

Description:

Parameter 0 of method rabbitTemplate in com.example.boot.message.amqp.AmqpConfig required a bean of type 'org.springframework.amqp.rabbit.connection.ConnectionFactory' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'org.springframework.amqp.rabbit.connection.ConnectionFactory' in your configuration.

我在@WebMvcTest上遇到了相同的错误，但之前都工作得很好。

在@RestController类上的注入失败，我认为不应为@DataJpaTest对其进行扫描和加载。

问题的根本原因是应用程序类上的@ComponentScan批注，将@ComponentScan替换为@SpringBootApplication（scanBasePackages =“ com.example”）解决了该问题。
