自动任务类:
@PersistJobDataAfterExecution @DisallowConcurrentExecution public class ReCodeBack implements Job { private static final Logger LOGGER = LoggerFactory.getLogger(ReCodeBack.class); @Autowired ReCodeBackTag reCodeBackTag; @Override public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException { reCodeBackTag.backupsReCode(); } }
自动任务注解:
@PersistJobDataAfterExecution
@DisallowConcurrentExecution
任务需求是需要添加事务
运用spring注解@Transactional注解
/** * 添加(删除)表数据 * @param object * @param modular * @return */ @Transactional(rollbackFor = Exception.class) public int tableOperation (Object object,String modular){ int count = 0; try{ ....... }catch (Exception e) { LOGGER.info("[添加(删除)表数据] ERROR :{}", e.getMessage()); //事务回滚 TransactionAspectSupport.currentTransactionStatus().setRollbackOnly(); //任务异常中断,立即重新运行 JobExecutionException e2 = new JobExecutionException(e); e2.setRefireImmediately(true); throw e2; }finally { return count; } }
注意:当作者在自动任务类进行使用@Transactional注解时,程序会进行报错(太懒……原因没搞清楚,后续会补上),所以作者分成了两个类来编写的,一个定时调用类,一个业务类,如上代码。
