    //生成一个执行器(事务包含在执行器里)
    final Executor executor = configuration.newExecutor(tx, execType);
    //然后产生一个DefaultSqlSession
    return new DefaultSqlSession(configuration, executor, autoCommit);
  } catch (Exception e) {
    //如果打开事务出错，则关闭它
    closeTransaction(tx); // may have fetched a connection so lets call close()
    throw ExceptionFactory.wrapException("Error opening session.  Cause: " + e, e);
  } finally {
    //最后清空错误上下文
    ErrorContext.instance().reset();
