创建我的第一个java网络
原标题:creating my first java web app

从阅读关于SO的一些链接来看,它跨越了建立 j网的游戏机。 我无法确定我的选择是否适合我的测试项目。

熟悉在互联网上这样做,但试图沿途学习java

缺省页显示提交纽伦文的以下文字领域:

enter fname

enter lname

enter dob

enter zipcode

以上领域及其案文应由专案或公文驱动。 它希望使用一个汇辑,使用户能够增加进入的新领域。

数据的收集并放在文本档案中,我的机器上的神话并没有正确装载。

i 对任何指导都负有很大责任。

最佳回答

我建议查看Yabe tutorial,以学习如何书写使用数据库的申请。 辅导相当清晰,是该项目的一部分,因此由“游戏”专家撰写! 可查阅models和JPA关于游戏文件现场的资料。

On a bit of a side note, I have worked on several projects that used dynamically generated fields stored in databases. This led to pretty miserable performance, since you need to create a table that is something like

create textfields ( entity int, label varchar(100), value varchar(255) );

在实体是文本领域(例如用户)描述的事物的情况下,标签就象手法一样,价值相当于12345(Albany, NY)。 现在,你们正在每个实体退回多行。 你们必须给任何预期领域带来足够大的价值。 采用高压法进行搜索的效率相当低,特别是如果你能向数百万用户推广。

游乐公司为NSQL数据库提供了极好的支持。 一旦你对游戏框架感到安慰,你就可以调查其他一些数据库。 如果你想在网上书写一个能够改变每个实体的田地的生产系统,那么比一个关系数据库更能选择一个比较小的数据库。
