java - 如何获取 Spring Batch Integration 测试来加载我的应用程序属性？

Question

我的 src/test/java 中有以下 Spring Batch 测试:

@RunWith(SpringRunner.class)
@SpringBatchTest
@EnableAutoConfiguration
@ContextConfiguration(classes= MyBatchConfig.class)
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
                                DirtiesContextTestExecutionListener.class})
@DirtiesContext(classMode = ClassMode.AFTER_CLASS)
@ActiveProfiles("local-test")
public class MyIntegrationTest {
    @Autowired
    private JobLauncherTestUtils jobLauncherTestUtils;

    @Autowired
    private JobRepositoryTestUtils jobRepositoryTestUtils;

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

我定义了我的test/resources/application-local-test.yml:

spring:
  profiles:
    active: "test"
  datasource:
    driverClassName: org.h2.Driver
    url: jdbc:h2:mem:TEST_DB;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1;IGNORECASE=TRUE;
    username: sa
    password: pwd
  jpa:
    open-in-view: true
    show-sql: true
    hibernate:
      dialect: org.hibernate.dialect.MySQL5Dialect
      ddl-auto: create
  h2:
    console: enabled

cloud:
  aws:
    s3:
      bucket: testBucket

在我的主应用程序中，一个 SpringBatch 配置:

@Configuration
@EnableBatchProcessing
public class ImportProjectsBatchConfig {

    public static final String JOB_NAME = "myJob";

    private String s3BucketName;

    public ImportProjectsBatchConfig(
            @Value("${cloud.aws.s3.bucket}")
                    String s3BucketName) {
        this.s3BucketName = s3BucketName;
    }

    @Bean
    public String s3BucketName() {
        return s3BucketName;
    }

    @Bean
    public SimpleStepBuilder<WebProject, WebProject> simpleStepBuilder(StepBuilderFactory stepBuilderFactory,
            ItemProcessor itemProcessor, ItemWriter itemWriter,
            MyErrorItemListener errorItemListenerSupport) {
        return stepBuilderFactory.get(JOB_NAME).<WebProject, WebProject>chunk(chunkSize)
                .processor(itemProcessor).listener((ItemProcessListener) errorItemListenerSupport)
                .writer(itemWriter).listener((ItemWriteListener) errorItemListenerSupport);
    }

}

当我尝试运行集成测试时，我的 application-local-test.yml 没有被获取:

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'cloud.aws.s3.bucket' in value "${cloud.aws.s3.bucket}"
    at org.springframework.util.PropertyPlaceholderHelper.parseStringValue(PropertyPlaceholderHelper.java:178)

我做错了什么？

Answer 1

我在使用 @SpringBatchTest 编写集成测试时遇到了无法加载 application.yaml 的相同情况。

我最终添加了 @SpringBootTest 来解决问题。

根据document , @SpringBatchTest 为测试注册像 JobLauncherTestUtils, JobRepositoryTestUtils...等 bean。

但是，如果我们想要启用 spring boot 功能，例如加载应用程序属性，添加 @SpringBootTest 似乎是一种方法。 ( document )
