以前一个项目，从mysql转移到达梦，snaker这块用不了了，应该是事务拦截这块的事务隔离有问题

public class NutzTransactionInterceptor extends TransactionInterceptor {
    private static final Logger log = LoggerFactory.getLogger(NutzTransactionInterceptor.class);
    public void initialize(Object accessObject) {
        //ignore
    }

    protected TransactionStatus getTransaction() {
    	try {
            boolean isNew = false;
            if(Trans.get() == null) {
                Trans.begin(Connection.TRANSACTION_REPEATABLE_READ);
                isNew = true;
            }
            return new TransactionStatus(Trans.get(), isNew);
        } catch (Exception e) {
            log.error(e.getMessage(), e);
            throw new RuntimeException(e.getMessage(), e);
        }
    }

    protected void commit(TransactionStatus status) {
        try {
            Trans.commit();
        } catch (Exception e) {
            throw new RuntimeException(e.getMessage(), e);
        } finally {
            try {
                Trans.close();
            } catch (Exception e) {
                log.error(e.getMessage(), e);
                throw new RuntimeException(e.getMessage(), e);
            }
        }
    }

    protected void rollback(TransactionStatus status) {
        try {
            Trans.rollback();
        } catch (Exception e) {
            throw new RuntimeException(e.getMessage(), e);
        } finally {
            try {
                Trans.close();
            } catch (Exception e) {
                log.error(e.getMessage(), e);
                throw new RuntimeException(e.getMessage(), e);
            }
        }
    }
}

Trans.begin(Connection.TRANSACTION_REPEATABLE_READ);这句话有错，还是觉得snaker轻量级 ，uflo2还要hibernate，不喜欢

Trans.begin(Connection.TRANSACTION_REPEATABLE_READ);改这句话？ 可是我不知道大梦有几种事务隔离。。网上都没有大梦的jar包源码。。蛋疼 中央库都没达梦的jar。。。

那为啥达梦的会报错。如果就四种的话。
