Spring boot Spring引导（Spring批处理）配置禁用数据库的自动创建

我将Spring boot与Spring Batch一起使用，我的application.properties中有datasource配置，但我不希望Spring Batch在我的数据库中创建表，因此我使用以下配置

@Configuration
@EnableBatchProcessing
public class BatchConfiguration {

@Autowired
public JobBuilderFactory jobBuilderFactory;

@Autowired
public StepBuilderFactory stepBuilderFactory;

@Bean
public Job myJob() {
    return jobBuilderFactory.get("myJob").incrementer(new RunIdIncrementer())
            .listener(listener()).flow(step2()).end().build();
}

@Bean
public JobRegistryBeanPostProcessor jobRegistryBeanPostProcessor(final JobRegistry jobRegistry) {
    JobRegistryBeanPostProcessor jobRegistryBeanPostProcessor = new JobRegistryBeanPostProcessor();
    jobRegistryBeanPostProcessor.setJobRegistry(jobRegistry);
    return jobRegistryBeanPostProcessor;
}

@Bean
public Step step2() {
    LOGGER.info("step2");
    return stepBuilderFactory.get("step2").tasklet(new PurchaseStatusBatch()).build();
}

@Bean
public JobOperator jobOperator() throws Exception {
    SimpleJobOperator jobOperator = new SimpleJobOperator();
    jobOperator.setJobExplorer(jobExplorer());
    jobOperator.setJobLauncher(jobLauncher());
    jobOperator.setJobRegistry(jobRegistry());
    jobOperator.setJobRepository(getJobRepo());
    return jobOperator;
}

@Bean
public JobRegistry jobRegistry() {
    return new MapJobRegistry();
}

@Bean
public JobExplorer jobExplorer() throws Exception {

    MapJobExplorerFactoryBean factoryExplorer = new MapJobExplorerFactoryBean(
            new MapJobRepositoryFactoryBean(getTransactionManager()));
    factoryExplorer.afterPropertiesSet();
    return factoryExplorer.getObject();
}

@Bean
public JobLauncher jobLauncher() throws Exception {
    SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
    jobLauncher.setJobRepository(getJobRepo());
    jobLauncher.afterPropertiesSet();
    return jobLauncher;
}

@Bean
public PlatformTransactionManager getTransactionManager() {
    return new ResourcelessTransactionManager();
}

@Bean
public JobRepository getJobRepo() throws Exception {
    return new MapJobRepositoryFactoryBean(getTransactionManager()).getObject();
}
}

我使用

spring.batch.initializer.enabled=false

来禁用数据库表的自动创建

在应用程序的第一次运行期间，一切正常，但当我尝试完成我的工作时，我得到了MySQLSyntaxErrorException：

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:表 “批处理作业实例”不存在

仅仅因为您已经禁用了表的自动生成，您仍然需要某种方法使这些实体可用。springbatch有两种机制。您可以手动或通过模式管理器（如Liquibase）创建这些数据库表。为此，请使用spring批处理核心资源中的SQL文件。否则，可以使用这些表的内存表示形式
