引入事务管理器 @Autowired TransactionTemplate transactionTemplate; @Autowired PlatformTransactionManager transactionManager; 使用方式1 //开启事务保存数据 boolean result = transactionTemplate.execute(new TransactionCallback<Boolean>() { @Override public Boolean doInTransaction(TransactionStatus status) { try { // TODO something } catch (Exception e) { //TransactionAspectSupport.currentTransactionStatus().setRollbackOnly(); //手动开启事务回滚 status.setRollbackOnly(); logger.error(e.getMessage(), e); return false; } return true; } }); 使用方式2 /** * 定义事务 */ DefaultTransactionDefinition def = new DefaultTransactionDefinition(); def.setReadOnly(false); //隔离级别,-1表示使用数据库默认级别 def.setIsolationLevel(TransactionDefinition.ISOLATION_READ_COMMITTED); def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED); TransactionStatus status = transactionManager.getTransaction(def); try { //TODO something transactionManager.commit(status); } catch (Exception e) { transactionManager.rollback(status); throw new InvoiceApplyException("异常失败"); } 使用方式3 SqlSession sqlSession = null; try { sqlSession = otInvSqlSessionFactory.openSession(ExecutorType.BATCH, true); XXXXXMapper xXxxMapper = sqlSession.getMapper(XXXXXMapper.class); sqlSession.commit(); }catch(Exception e){ if (null != otInvSqlSession) { sqlSession.rollback(true); logger.error("数据回滚", e); } }finally { if (null != sqlSession) { sqlSession.clearCache(); sqlSession.close(); } }
