在运行时从XML构建对象的最佳方法(Best way for building objects out of XMLs at runtime)

我遇到的情况是我有很多XML,它们是从服务器发送给我的,我使用的是JAXB或任何基于该体系结构的API来构建对象实例。

问题是,我必须在编译时确定要解组的类。 在我看来,我的解决方案是读取传入的XML对象并基于某些标记,我将指示unmrashaller创建指定类的实例。 这种方法会让我有很多IF语句和大型状态机。

有更好的设计模式或方法吗?


I'm in a situation that I have a lot of of XMLs, that are sent to me from a server and I'm using JAXB or any API based on that architecture for building instances of objects.

The problem is, I have to per-determine the class that I want to unmarshall for at compile time. My solution that is in my mind, is to read the incoming XML object and based on some tags, I will direct the unmrashaller to make an instance of the specified class. That approach will let me have a lot of IFs statements and big state machine.

Is there a better design pattern or approach ?

最满意答案

尝试使用Apache digester 3 ,我认为它可以为你节省很多“if”,并且根本不难使用。

看看这篇文章: http//www.javaworld.com/javaworld/jw-10-2002/jw-1025-opensourceprofile.html


Try using Apache digester 3, I think it can save you lots of "if"s and is not difficult to use at all.
