ibatis2.3.0到2.3.4变化莫测

最近项目打算升级ibatis原来项目基于jdk1.4所以ibatis用的版本是ibatis-2.3.0.677

 

现在jdk用的都是1.5所以打算用ibatis-2.3.4

 

原本以为  直接换个jar就可以

 

结果 跑步起来了，，不是说ibatis问题

 

原因 当初 为支持 ibatis物理分页 扩展了 ibatis[原来考虑ibatis升级，没有改源代码，自己增加扩展类]

 

但是2.3.0版本的SessionScope的属性名称是session到2.3.4就变成sessionScope   --》无语了吧

 

还有2.3.0的RequestScope再2.3.4里面消失了，所以我的代码全部修改

 

只能用2.3.4里面的StatementScope

 

ibatis的参数值放的对象也变了方法也变了

 

还好 原来对2.3.0源代码读过，2.3.4变化 基本掌握

 

修改over

 

进一步体会开源的不兼容版本

 

2.3.4的代码基本说是不负责任的代码

 

比如：

/**
 * A Session based implementation of the Scope interface
 */
public class SessionScope {

 

  //省略内容

}

 

2.3.0是接口-抽象类-类

2.3.4直接就是类，但是注释还是2.3.0的

开源 需要 精神啊

这样下去 不知道 ibatis质量会怎么样

 

难道是ibatis看重3.0所以2.3.4就。。。。

不同版本不兼容太烦人了

用开源的东西兼容性是挺麻烦的

哎，我也碰到了这些问题。

ibatis烦就烦在他在statement级别的api不是对外公开的，所以没事老变，也不知道是不是故意为之，反正让我用起来很不爽。

哪位大哥哪天高兴了弄个对头产品，看他还敢不敢这么乱搞。

其实 hibernate ibatis也好都可以扩展支持枚举的；

只不过心版本都内置支持了，不过觉得支持还不够完美；

还是自己在扩展哈！

我现在用hibernate 想用enum 写一大堆东西 烦心？？

hibernate支持枚举的，自己封装哈；

很简单的；
