如何使用JUnit 5在SpringBoot 2中的任何Application Bean之前创建测试Bean

Question

我正在尝试创建一个Spring Boot 2集成测试，以启动嵌入式Elasticsearch（使用JUnit 5和junit-jupiter-api）

问题是引导应用程序中的Elasticsearch Client在EmbeddedElastic之前启动，因此无法连接。使用@Order(Ordered.HIGHEST_PRECEDENCE)似乎无效。

@ExtendWith(SpringExtension.class)
@SpringBootTest(classes = {MyApplication.class})
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@TestPropertySource(locations = "classpath:/test.properties")
public class MyAppIT {

    @Autowired
    private EmbeddedElastic embeddedElastic;

    @BeforeAll
    public void beforeAll() throws Exception {
        EmbeddedElastic elastic = embeddedElastic.start();
        System.out.println("embeddedElastic running on port = " + elastic.getHttpPort());
    }

    @Test
    public void testOne() throws Exception {
        System.out.println("testOne");
    }

}

@Configuration
public class TestConfiguration {

    @Bean
    @Order(Ordered.HIGHEST_PRECEDENCE)
    public EmbeddedElastic embeddedElastic() {
        return EmbeddedElastic.builder()
                .withElasticVersion("6.6.0")
                .withSetting(PopularProperties.TRANSPORT_TCP_PORT, 9300)
                .withSetting(PopularProperties.CLUSTER_NAME, "test_cluster")
                .withCleanInstallationDirectoryOnStop(false)
                .build();
    }

}
