spring - 取消刷新尝试：org.springframework.beans.factory.BeanCreationException：创建名为“MyTastTasklet”的bean时出错

Question

我正在开发Spring Boot Batch Example。在这个例子中，我创建了 BatchJPA 核心模块，它具有实体、JPARepository 和 DB 配置。

该模块作为依赖项添加到另一个 Spring 模块中，在此模块中，我正在添加与代码相关的特定批处理作业（如自定义存储库等）。我总共有 15 个批处理作业，我将使用 BatchJPA 依赖项创建单独的 Spring Boot 项目。

Description:

A component required a bean named 'transactionManager' that could not be found.


Action:

Consider defining a bean named 'transactionManager' in your configuration.

下面的代码：

@Service
public class MyTaskTasklet implements Tasklet {

    @Autowired
    private MyCustomerCustomRepository myCustomerCustomRepository;

    @Override
    public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {

        List<MyTest> mydata = myCustomerCustomRepository.getElligibleData();
        if (!mydata.isEmpty()) {
            System.out.println("XXXXXX = " + mydata.size());
        }

        chunkContext.getStepContext().getStepExecution().getJobExecution().getExecutionContext()
                .put("listOfData", mydata);

        return RepeatStatus.FINISHED;
    }
}

另一个文件：

@Component
@EnableBatchProcessing
public class MyJobLauncher {

    public void executeJob() {
        String[] springConfig = { "jobs/ABC.xml"};

        ApplicationContext context = new ClassPathXmlApplicationContext(springConfig);

        JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
        Job job = (Job) context.getBean("MyJobId");

        try {
            JobParameters jobParameters = new JobParametersBuilder().addString("runMode", "DATA")
                    .addDate("date", new Date()).addLong("time", System.currentTimeMillis()).toJobParameters();
            jobLauncher.run(job, jobParameters);
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }
}

和另一个文件 MainApplication

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
public class MainApplication implements CommandLineRunner {

    @Autowired
    private MyJobLauncher jobLauncher;

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

    @Override
    public void run(String... args) throws Exception {
        jobLauncher.executeJob();
    }
}
