对oracle数据库进行增删改更新操作，executeUpdate()执行卡住了

//增删改
    public int executeUpdate(String sql,Object[] params){
        int update = 0;
        try {
            pstm = connection.prepareStatement(sql);
            for(int i=0;i<params.length;i++){
                pstm.setObject(i+1, params[i]);
            }
            update = pstm.executeUpdate();
            //oracle更新操作要commit不然事务堵塞执行不成功
            connection.commit();
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return update;
    }
