子实体的参数和数据表的详细信息

分类：编程问答

如何解决子实体的参数和数据表的详细信息

我正在编写Java EE应用程序，以对公司员工进行年度评估。我想在单击“详细信息”时显示每个协作者的评估详细信息。

受影响的3个表是“ Collaborateur”，“ Entretien”和“ NoteEntretien”

因此，当我选择一个协作者并单击“查看详细信息”时，我想重定向到一个新页面，其中包含表单上的协作者详细信息以及评估后的数据表。当我单击评估详细信息时，应该重定向到另一页，其中包含评估的不同注释。

我使用的是JSF 2.x，前面是Primefaces 5.0，持久性是EclipseLink，业务方面是EJB 3.1。

我已经有了解决方案，可以在弹出窗口中显示协作者详细信息，而无需数据表以及协作者评估。

请帮助我找到最佳方法。

谢谢！

解决方法

这是一个复杂的问题。没有“最佳解决方案”。我只是可以推荐一些实现它的方法。

  1. 准备一个单独的模板页面，其中包含 URL 和控制器 CollaborateurDetailController。
  2. 在该控制器的 init() 方法中，从 URL 中获取 "id" 参数，并从该控制器的 "Selected" 中通过 id 获取编辑后的实体。或者，如果没有 "id"，则创建一个新实例。
  3. 更改列表中编辑按钮上的侦听器以重定向到带有 "id" 参数的新控制器页面，或重定向到创建按钮的空白页面。

我建议为细节制作单独的控制器。在成熟的项目中，您将需要详细实现复杂的表单和组件。模态窗口是一个基本的解决方案，在很多情况下，您将来只需要重构即可。
