spring事务问题?报错

dataSource.setDefaultAutoCommit(false);
		JdbcTemplate template = new JdbcTemplate(dataSource);
		DataSourceTransactionManager tran = new DataSourceTransactionManager(dataSource);
		DefaultTransactionDefinition def = new DefaultTransactionDefinition();//事务定义类
		def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
		TransactionStatus status = transactionManager.getTransaction(def);//返回事务对象
		try {
			String sql = "update TB_MEMBER set ACCOUNT=ACCOUNT+? where OPENID=?";
			String sql2 = "update TB_MEMBER set ACCOUNT=ACCOUNT+? where OPENID=?";
			template.update("update TB_MEMBER set ACCOUNT=ACCOUNT+"+account+" where OPENID='"+openid+"'");
			template.update("update TB_MEMBER set ACCOUNT=ACCOUNT+"+account+" where OPENID="+openid);
			transactionManager.commit(status);
		} catch (Exception ex) {
			System.out.println("##############3抛异常");
			transactionManager.rollback(status);
		}finally{
			dataSource.setDefaultAutoCommit(true);
		}

问题描述：第一条sql是正常的，执行的时候第二条报错，但是第一条的操作还是会入库，我的预想是两条都回滚。求大神帮忙看看。
