执行端到端测试时数据库未初始化

问题描述 投票：0回答：1

我正在尝试在 spring-batch 项目上构建端到端测试，但是，当尝试运行单个步骤的执行时，数据库似乎未初始化。 

contextLoads
测试运行正常，自定义itemReader的单独测试也运行正常，所以我假设spring批处理本身的配置上缺少一些东西，但不知道是什么。

应用：

@EnableTransactionManagement
@SpringBootApplication
public class DadosSegurancaApplication {

    public static void main(String[] args) {
        SpringApplication.run(DadosSegurancaApplication.class, args);
    }

}

作业配置

@Configuration
public class JobConfigs extends DefaultBatchConfiguration {

...
    @Bean
    public Step loadSubtractedObjectToDbStep(JobRepository jobRepository, PlatformTransactionManager transactionManager, ExcelReader excelReader, RepositoryItemWriter<SubtractedObject> subtractedObjectItemWriter) {
        return new StepBuilder("loadSubtractedObjectToDbStep", jobRepository)
                .<SubtractedObject, SubtractedObject>chunk(ROWS_PER_CHUNK, transactionManager)
                .reader(excelReader)
                .writer(subtractedObjectItemWriter)
                .build();
    }

    @Bean
    public Job subtractedObjectsJob(JobRepository jobRepository, Step loadSubtractedObjectToDbStep) {
        return new JobBuilder("subtractedObjectsJob", jobRepository)
               .start(loadSubtractedObjectToDbStep)
               .build();
    }
...

}

应用属性：

spring.datasource.url=jdbc:h2:file:./local.db
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=
spring.datasource.password=
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=update
spring.batch.initialize-schema=always

测试

@SpringJUnitConfig
@SpringBatchTest
@SpringBootTest(classes = { DadosSegurancaApplication.class })
public class SubtractedObjectExcelStepTest {

    @Autowired
    private ExcelReader reader;

    @Autowired
    private JobLauncherTestUtils jobLauncherTestUtils;

    @Autowired
    private Job subtractedObjectsJob;

    @Test // FAILS WITH ERROR BELLOW
    public void executeSingleStep() {
        jobLauncherTestUtils.setJob(subtractedObjectsJob);
        jobLauncherTestUtils.launchStep("loadSubtractedObjectToDbStep");
    }

    @Test // WORKS
    public void testAllReads() throws Exception {
        assertSingle(reader.read(), "READ");
        assertSingle(reader.read(), "READ2");
        assertSingle(reader.read(), "READ3");
        Assertions.assertNull(reader.read());
    }

}

对于为什么即使应用程序启动并配置正常，数据库中的表未初始化有什么想法吗？

java spring-boot spring-batch spring-boot-test spring-autoconfiguration

这是因为你的配置类扩展了

DefaultBatchConfiguration
，这使得Spring Boot的自动配置功能退缩（参见这个note）。因此，你需要自己用批处理表初始化数据库。
