我长时间运行 tasklet 运行了 20 小时，任务完成后，由于 mysql 连接关闭，我在 Spring 批处理中遇到错误。
下面是我的工作配置
@Configuration
@EnableBatchProcessing
@Slf4j
public class BatchConfig extends DefaultBatchConfigurer {
@Override
@Autowired
public void setDataSource(@Qualifier("batchDataSource") DataSource batchDataSource) {
log.info("DataSource : " + batchDataSource);
super.setDataSource(batchDataSource);
}
public DataSource batchDataSource() {
HikariDataSource dataSource = new HikariDataSource();
dataSource.setDriverClassName(driverClassName);
dataSource.setJdbcUrl(url);
dataSource.setUsername(userName);
dataSource.setPassword(password);
dataSource.setPoolName("mysql");
dataSource.setMaximumPoolSize(10);
dataSource.setMinimumIdle(5);
return dataSource;
}
@Bean
public JobRegistryBeanPostProcessor jobRegistryBeanPostProcessor(JobRegistry jobRegistry) {
JobRegistryBeanPostProcessor jobRegistryBeanPostProcessor = new JobRegistryBeanPostProcessor();
jobRegistryBeanPostProcessor.setJobRegistry(jobRegistry);
return jobRegistryBeanPostProcessor;
}
@Bean("asyncJobLauncher")
public JobLauncher asyncJobLauncher(JobRepository jobRepository) {
final SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
jobLauncher.setJobRepository(jobRepository);
final SimpleAsyncTaskExecutor simpleAsyncTaskExecutor = new SimpleAsyncTaskExecutor();
jobLauncher.setTaskExecutor(simpleAsyncTaskExecutor);
return jobLauncher;
}
}
作业配置是
@Autowired
private JobBuilderFactory jobs;
@Autowired
private StepBuilderFactory steps;
@Autowired
private JobRepository jobRepository;
@Bean
public Job job(PimAutomationBatchServiceImpl pimAutomationBatchService) {
Step stepDownload = steps.get("download-pim-data")
.tasklet((stepContribution, chunkContext) -> {
pimAutomationBatchService.executeDownloadPimDataStep(chunkContext.getStepContext());
return RepeatStatus.FINISHED;
})
.listener(new StepListener())
.build();
Step stepTtlGeneration = steps.get("ttl-generation")
.tasklet((stepContribution, chunkContext)->{
pimAutomationBatchService.executeTTLGenerationStep(chunkContext.getStepContext());
return RepeatStatus.FINISHED;
}).listener(new StepListener()).build();
return jobs.get("PimSync")
.listener(new JobResultListener(jobRepository))
.start(stepDownload)
.next(stepExtract)
.next(stepTtlGeneration)
.build();
}
ttl 生成步骤耗时 20 小时，必须处理 330GB 数据。
完成此步骤后，我遇到了错误。请建议。
