Spring Batch端到端测试配置不起作用

Question

我遵循了官方的Spring batch guide (https://spring.io/guides/gs/batch-processing/)并成功地完成了示例。对于同样的工作，我正在尝试创建一个端到端的集成测试。特别是我只使用测试配置。在我的测试中，我定义了所有需要的bean。因此，这应该是运行该作业所需的唯一配置。这提供了很大的灵活性。创建ApplicationContext时测试失败。它抱怨说它找不到数据源。当我运行实际的应用程序时，由于我使用的是内存中的数据库，spring会自动在数据库中创建数据源和spring批处理相关的表。但是当我运行我的测试时，它不会自动创建数据库。我如何触发spring来做到这一点呢？

在我的测试配置中，当我添加显式数据源bean配置时，它会创建数据源，但不会在数据库中创建与spring批处理相关的表。

以下是测试代码：

@SpringBatchTest
@RunWith(SpringRunner.class)
public class PersonJobTest {

    @Autowired
    private JobLauncherTestUtils jobLauncherTestUtils;

    @Test
    public void testPersonJob() throws Exception{

        JobExecution jobExecution = jobLauncherTestUtils.launchJob();
        assertEquals("COMPLETED", jobExecution.getExitStatus().getExitCode());
    }


    @Configuration
    @EnableBatchProcessing
    public static class JobConfig {

        @Autowired
        public JobBuilderFactory jobBuilderFactory;

        @Autowired
        public StepBuilderFactory stepBuilderFactory;

        private JdbcTemplate simpleJdbcTemplate;

        @Bean
        public FlatFileItemReader<Person> reader() {
            return new FlatFileItemReaderBuilder<Person>()
                    .name("personItemReader")
                    .resource(new ClassPathResource("sample-data.csv"))
                    .delimited()
                    .names(new String[]{"firstName", "lastName"})
                    .fieldSetMapper(new BeanWrapperFieldSetMapper<Person>() {{
                        setTargetType(Person.class);
                    }})
                    .build();
        }

        @Bean
        public PersonItemProcessor processor() {
            return new PersonItemProcessor();
        }

        @Bean
        @Autowired
        public JdbcBatchItemWriter<Person> writer(DataSource dataSource) {
            return new JdbcBatchItemWriterBuilder<Person>()
                    .itemSqlParameterSourceProvider(new BeanPropertyItemSqlParameterSourceProvider<>())
                    .sql("INSERT INTO people (first_name, last_name) VALUES (:firstName, :lastName)")
                    .dataSource(dataSource)
                    .build();
        }

        @Bean
        public JdbcTemplate jdbcTemplate(DataSource dataSource) {
            return new JdbcTemplate(dataSource);
        }

        @Bean
        public JobCompletionNotificationListener getListener(JdbcTemplate jdbcTemplate){
            return new JobCompletionNotificationListener(jdbcTemplate);
        }

        @Bean
        public Job importUserJob(JobCompletionNotificationListener listener, Step step1) {
            return jobBuilderFactory.get("importUserJob")
                    .incrementer(new RunIdIncrementer())
                    .listener(listener)
                    .flow(step1)
                    .end()
                    .build();
        }

        @Bean
        public Step step1(JdbcBatchItemWriter<Person> writer) {
            return stepBuilderFactory.get("step1")
                    .<Person, Person> chunk(10)
                    .reader(reader())
                    .processor(processor())
                    .writer(writer)
                    .build();
        }
    }


}

在运行测试时，我希望spring boot自动配置数据源，并像运行实际应用程序时一样创建与spring批处理相关的表。

为此，您需要使用@SpringBootTest注释。此外，您不需要在测试中复制作业配置。以下是入门指南中通过的测试：

import org.junit.Test;
import org.junit.runner.RunWith;

import org.springframework.batch.core.JobExecution;
import org.springframework.batch.test.JobLauncherTestUtils;
import org.springframework.batch.test.context.SpringBatchTest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import static org.junit.Assert.assertEquals;

@SpringBatchTest
@SpringBootTest
@RunWith(SpringRunner.class)
public class PersonJobTest {

    @Autowired
    private JobLauncherTestUtils jobLauncherTestUtils;

    @Test
    public void testPersonJob() throws Exception{
        JobExecution jobExecution = jobLauncherTestUtils.launchJob();
        assertEquals("COMPLETED", jobExecution.getExitStatus().getExitCode());
    }

}
