Spring Boot 3:具有模块化上下文的Batchapplication不会启动任何作业

spring-batch

Manu · 技术社区 · 3 年前

我升级到了Spring Boot 3,当我通过 --spring.batch.job.names 。

这是我的主要课程:

@SpringBootApplication
@EnableJpaRepositories("path.to.my.repositories")
@EntityScan("path.to.my.entities")
public class MyBatchApplication{
    public static void main(String[] args) {
        System.exit(SpringApplication.exit(SpringApplication.run(MyBatchApplication.class, args)));
    }

}

这是我的配置

@Configuration
@EnableBatchProcessing(modular = true)
public class MyModularBatchJobContextConfiguration {
    @Bean
    ApplicationContextFactory getJobAContext() {
        return new GenericApplicationContextFactory(JobAConfig.class);
    }

    @Bean
    ApplicationContextFactory getJobBContext() {
        return new GenericApplicationContextFactory(JobBConfig.class);
    }
}

和 JobA.class 和 JobB.class 基本上是一样的:

public class JobAConfig {

    private static final String MY_JOB_NAME = "jobA"

    @Autowired
    private EntityManagerFactory emf;

    @Bean
    public Job jobA(JobRepository jobRepository, Step myStep) {
        return new JobBuilder(MY_JOB_NAME, jobRepository)
                .flow(myStep)
                .end()
                .build();
    }

    @Bean
    public Step myStep(JpaTransactionManager transactionManager,
                       JobRepository jobRepository,
                       FlatFileItemReader<MyEntity> reader,
                       ItemProcessor<MyEntity, MyEntity> processor,
                       JpaItemWriter<MyEntity> entityWriter) {
        return new StepBuilder(MY_STEP_NAME, jobRepository)
                .<MyEntity, MyEntity>chunk(10, transactionManager)
                .reader(reader)
                .processor(processor)
                .writer(plzOrtEntityWriter)
                .transactionManager(transactionManager)
                .build();
    }

// Reader, Writer, Processor...

当我和 java -jar mybatchapplication.jar --spring.batch.job.names=jobA 什么也没发生,作业没有开始。

有人知道这里出了什么问题吗? 我也试过 --spring.batch.job.name= ,没有成功。

使用Spring Boot 3,无需 @EnableBatchProcessing 。如果添加它,Spring Batch的自动配置(元数据表创建、启动时启动作业等)将停止 migration guide 弹簧套3。

因此,在您的情况下,如果您想模块化您的上下文,您有两个选项:

继续使用 @启用批处理 从中受益 modular = true ,但在这种情况下,您必须手动执行Spring Boot以前的操作(即初始化数据库、在启动时运行作业等)。
或删除 @启用批处理 (像以前一样受益于Boot 3功能),但在这种情况下,您需要手动模块化上下文

在属性文件中添加:

spring.batch.job.enabled: true
