关注GWT

随着Ajax在Web开发上的使用日益广泛，GWT也越来越受到关注。GWT从根本上将Ajax的开发大大地向前推进，开发人员可以轻松使用 Java 编写 AJAX 前端。只要看看Google 的 Gmail, Doc 等卓越的网络应用，你就可以认识到GWT所带来的好处。这几天看了一下最新版GWT v1.7的API，想和大家一起探讨一下。

 

这一整套API包括了四大块内容：

* Gadgets

      Gadgets 说白了就是一些可以嵌入网页或网络应用的小控件，而相关的API则提供了对这些控件的开发和控制。

 

* Gears

      Gears API 提供了对本地服务器，数据库，工作池和离线应用的支持。

 

* Google AJAX Search

      Google AJAX Search API 可以将Google的强大搜索功能集成到你的网络应用中去，支持本地搜索，网络搜索甚至多媒体搜索。

 

* Google Visualization

      Google Visualization API 可以将你想要对外发布的数据以可视化的形式表现出来，包括了图表，时间轴或者是地理信息图。

All GWT and EXT are great for user interfaces. I'm sure you can create equally good UI's with any.

But GWT however is in a different category. Although it does do Ajax user interfaces it is more than just a user interface library. It aims to provide many tools to bring real software engineering to Ajax applications.

GWT would have additional boxes for:

- server interoperation (HTTP, XML, JSON, GWT RPC)

- internationalization

- code obfuscation

- code optimization

- automatically cross browser (even the code you write)

- unit testing

- eclipse (or any Java IDE)

- modularization and java organization/OOP

- easy application versioning

- performance (image bundles, caching considerations)

- code generation

There's quite a bit. Also the GWT engineers are great and constantly working on improving the compiler which means your code automatically runs better with new releases.

GWT 2.0 will release in the end of this year, and you can see lots of improvement from it.
