问题描述


$ b 我使用IDE'hibernate代码生成生成hibernate beans, / p>

2)另外,我已经使用maven编译器生成了jaxb bean。



..



现在,我的问题是,

这是正确的方法吗? (要有这么多的bean)。

我应该使用JAXb beans来处理服务层吗?我如何保持图层的分离?



3)或者,是否需要创建另一组bean,即。将(新的bean)映射(jaxb beans)到(hibernate beans)?



请告诉你如果您有任何疑问,请联系我们,我们会尽快为您解答。

知道,你不能让一切都完全分离。总会有一层会知道其他两层。



通常当我设计3层架构时,比如:


  1. 服务层 - 可能使用JAXB的服务层,公开Web服务或其他API

  2. 业务层 - 任何实际逻辑
  3. 持久层 - hibernate

我允许业务层了解服务层(JAXB)和持久性图层(休眠豆)。但是我不允许服务层和持久层相互了解。

Currently I am working on a project with Spring web-service, hibernate and JAXb.

1) I have generated hibernate beans using IDE 'hibernate code generation,

2) also, I have generated the jaxb beans using maven compiler.

..

Now, my question is,

1) Is this the right approach? (to have so many beans).

2) Shall I use JAXb beans for processing into the service layer? How can I keep layers decoupled?

3) Or, do I need to create another set of beans ie. map (JAXb beans) to (new beans) to (hibernate beans)?

.

Please tell your views?

Thanks,adi

解决方案

You know, you cannot have everything fully decoupled. There will be always a layer that will know the other two layers.

Usually when I design 3 layers architecture, like:

  1. Service Layer - the one that probably uses JAXB, exposes web services or other APIs
  2. Business Layer - any real logic
  3. Persistence Layer - hibernate

I allow the Business layer to know about the Service Layer (JAXB) and about the Persistence Layer (hibernate beans). But I don't allow the Service Layer and the Persistence Layer to know about each other.
