Recommended JSF 2.0 CRUD frameworks
提问by Jan
Can somebody recommend any framework to facilitate CRUD development in JSF 2.0?
有人可以推荐任何框架来促进 JSF 2.0 中的 CRUD 开发吗？
Aspects I value most:
我最看重的方面：
- As lightweight as possible; limiteddependencies on third party libraries
- Support for an evolvingdomain model
- Limited need for repetitive coding; support for scaffolding and/or metaannotations
- 尽可能轻巧；对第三方库的依赖有限
- 支持不断发展的领域模型
- 对重复编码的需求有限；支持脚手架和/或元注释
Any hints highly appreciated! Yours, J.
任何提示高度赞赏！你的，J。

CRUD is indeed a piece of cake using JSF 2.0 provided standard facility: a @ViewScopedbean in combination with a <h:dataTable>basically already suffices. Here's a code example which is shamelessly copied from this article.
CRUD 确实是小菜一碟，使用 JSF 2.0 提供的标准设施：一个@ViewScopedbean 结合一个<h:dataTable>基本上就已经足够了。这是从本文中无耻地复制的代码示例。
Bean:
豆角，扁豆：
package com.example;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
@ManagedBean
@ViewScoped
public class Bean implements Serializable {
private List<Item> list;
private Item item = new Item();
private boolean edit;
@PostConstruct
public void init() {
// list = dao.list();
// Actually, you should retrieve the list from DAO. This is just for demo.
list = new ArrayList<Item>();
list.add(new Item(1L, "item1"));
list.add(new Item(2L, "item2"));
list.add(new Item(3L, "item3"));
}
public void add() {
// dao.create(item);
// Actually, the DAO should already have set the ID from DB. This is just for demo.
item.setId(list.isEmpty() ? 1 : list.get(list.size() - 1).getId() + 1);
list.add(item);
item = new Item(); // Reset placeholder.
}
public void edit(Item item) {
this.item = item;
edit = true;
}
public void save() {
// dao.update(item);
item = new Item(); // Reset placeholder.
edit = false;
}
public void delete(Item item) {
// dao.delete(item);
list.remove(item);
}
public List<Item> getList() {
return list;
}
public Item getItem() {
return item;
}
public boolean isEdit() {
return edit;
}
// Other getters/setters are actually unnecessary. Feel free to add them though.
}

Further, Netbeans has some useful wizardsto genreate a CRUD application based on a datamodel.
此外，Netbeans 有一些有用的向导来基于数据模型对 CRUD 应用程序进行分类。

JSF 2.0 itself. CRUD is very easy to do with JSF alone - no need for any other framework. You need
JSF 2.0 本身。CRUD 单独使用 JSF 非常容易——不需要任何其他框架。你需要
- 1 managed bean (annotated with
@ManagedBean) - 2 xhtml pages (facelets) - one for list and one for edit/create
- A
<h:dataTable>with aneditlink/button, by which you set the current row object in the managed bean (usingaction="#{bean.edit(currentRowObject)}"). (In JSF 1.2 this was achieved by<f:setPropertyActionListener>) - Action methods (
void, with no arguments) to handle the operations @PostConstructto load the data initially.
- 1 个托管 bean（用 注释
@ManagedBean） - 2 个 xhtml 页面（facelets）——一个用于列表，一个用于编辑/创建
<h:dataTable>带有edit链接/按钮的A ，您可以通过它在托管 bean 中设置当前行对象（使用action="#{bean.edit(currentRowObject)}"）。（在 JSF 1.2 中，这是通过 实现的<f:setPropertyActionListener>）- 处理操作的操作方法（
void，不带参数） @PostConstruct最初加载数据。

I had the same problem as described: Creating as-fast-as-possible CRUD-App in JEE6.
我遇到了与描述相同的问题：在 JEE6 中创建尽可能快的 CRUD-App。

After defining (Graph-Editor!) your Business-Model/Domain-Model, JBizMo creates the database and a whole CRUD-App out of the Box.

- i18n, JAAS, also supported
- Views and Menus are generated
- ... a bunch of parameters to define ...
- 也支持 i18n、JAAS

I created this one to speed up process of jsf crud application creation: https://github.com/ignl/happyfacescrudOut of box search, lazy data table, viewing/editing, custom components that reduces code dramatically and of course flexible.
我创建了这个来加速 jsf crud 应用程序的创建过程：https: //github.com/ignl/happyfacescrud开箱即用的搜索、惰性数据表、查看/编辑、自定义组件，可显着减少代码，当然也很灵活。
