Spring中三種編程式事務的使用

session sql close div something pan public 定義 red

  • 引入事務管理器
@Autowired
TransactionTemplate transactionTemplate;

@Autowired
PlatformTransactionManager transactionManager;

使用方式1:

boolean result = transactionTemplate.execute(new TransactionCallback<Boolean>() {
    @Override
    public Boolean doInTransaction(TransactionStatus status) {
        
try { // TODO something } catch (Exception e) { //TransactionAspectSupport.currentTransactionStatus().setRollbackOnly(); //手動開啟事務回滾 status.setRollbackOnly(); logger.error(e.getMessage(), e); return false; } return true
; } });

使用方式2:

/**
 * 定義事務
 */
DefaultTransactionDefinition def = new DefaultTransactionDefinition();
def.setReadOnly(false);
//隔離級別,-1表示使用數據庫默認級別
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("異常失敗"); }

使用方式3:

SqlSession sqlSession = null;
try {
    sqlSession = otInvSqlSessionFactory.openSession(ExecutorType.BATCH, true);
    XXXXXMapper xXxxMapper = sqlSession.getMapper(XXXXXMapper.class);
Savepoint savepointStep1 = sqlSession.getConnection().setSavepoint();
sqlSession.getConnection().rollback(savepointStep1); sqlSession.commit(); }
catch(Exception e){ if (null != otInvSqlSession) { sqlSession.rollback(true); logger.error("數據回滾", e); } }finally { if (null != sqlSession) { sqlSession.clearCache(); sqlSession.close(); } }
