H2 database，也是lightweight的，query都很简单，
但是不想直接写SQL了 |

发帖数: 4260 | 4 En. Thanks. For my current project, it's a tiny little
one, somehow I feel that hibernate with jpa is a little
heavy. I'll definitely use it for a larger project.
But maybe using hibernate JPA may not be a such bad
idea either, for a small project

发帖数: 3271 | 6 It depends on what do you mean by "tiny little". If you mean memory
footprint, then you probably should write the SQL. If you mean the amount of
code you have to write, then use JPA is a good choice because you will have
the luxury of switching implementations. Moreoever, there are probably
ready-to-use persistent List, Map, and etc in JPA that can save your efforts.

发帖数: 4260 | 7 I mean a couple of tables and simple relationships.
I'm using an embedded DB (h2) as data source. Just a
simple blog sample type of application, simple CRUD.
Because it's simple, I'm trying to avoid any XMLs,
or other type of configurations, or a whole bunch of
jar files (although jar files is a smaller problem.)

发帖数: 3271 | 8 Then you should write SQL. It is not complicated and will not increase your
dependency size.

很多应用直接用 jdbcTemplate 就足够了。
或者是 iBatis/myBatis 也很简单实用。

就是不知道稳定性如何，呵呵

不用自己装，用spring的 bean row mapper, 一点不麻烦。

发帖数: 4260 | 13 提到spring就觉得heavy啊，呵呵。用这个需要几个jar files？
I'm assuming it's relative independent，对spring的
其他东西有没有dependency？

发帖数: 3271 | 15 It's a myth that JPA / Hibernate is complicated, hehe.
Actually JPA is the simplest ORM I have ever used.
Hibernate is more complex, but you can ignore it and only use the JPA part.
If you use Java Annotation, you don't even need XML.
