【Csdn 7月31日报道】Google Web Toolkit (GWT)是一个开源的工具集，可以让Web开发人员用Java语言创建和维护复杂的JavaScript前端应用程序。它发布在Apache License version 2.0下。GWT的目标是：使开发人员可以使用现有的Java工具来在任何浏览器上构建AJAX，从而从根本上改善用户使用网络的体验。
谷歌今年晚些时候将推出GWT 2.0。虽然GWT的开发进程比较慢，然而这几年来一直稳步提升。让我们回眸GTW走过的岁月，并展望下它的未来：
先看看它的历史
* GWT 1.0 ：2006，5月17日
* GWT 1.1：2006年8月11日
* GWT 1.2 :2006年11月16日
* GWT 1.3：2007年2月5日
* GWT 1.4：2007年8月28日
* GWT 1.5：2008年9月27日
* GWT 1.6：2009年4月7日
* GWT 1.7：2009年7月13日
GWT 2.0的发布计划是在今年晚些时候，GWT 2.0将包含巨大的改进，包括动态脚本载入、一个新的编译器优化的目录，并以新的方式使用本地浏览器来支持宿主模式（hosted mode）调试。
宿主模式（hosted mode）是高效开发的一个关键因素，而且它有助于调试，编辑等。问题是宿主模式的浏览器如果很很特殊比如在Linux上、宿主浏览器是一个老版的Mozilla，就难以与其他技术（如Flash）交互，而且不可能在非开发操作系统（如Mac上的IE浏览器）上调试浏览器。GWT使大多数本地浏览器支持宿主模式，解决了这些问题。
另一个巨大的性能提升是编译器功能的增强，配备了新的工具包。新版本的GWT承诺将会提供更快速的编译速度。
另外一个新的特性是开发者可以自定义代码分割。通常的编译脚本代码，其大小是一个麻烦事，因为它拥有所有的代码，并且能够增长到很大。因此，初始下载就会很慢、脚本解析时UI悬挂等。GWT 2.0提供了一个解决方案使用runasync进行代码分割。编译器决定如何组织代码，而且确保是正确的。
另一个新特性是ClientBundle，它能够将ImageBundle扩展到任意资源类型。结合ClientBundle不仅图像捆绑在一起，所有的资源（如CSS ）都可以捆绑。最明显的好处是，只有一个文件实必须要下载的，因此，减少了HTTP请求，下载速度也更快。此外，CSS等资源的规模得到优化。在谷歌的I / O演讲中还提到，在下一个版本中， ClientBundle也许还将使用Base64来处理二进制资源。
在GWT2.0中，有可能会创造RPC黑名单，这个名单告诉RPC子系统跳过那些你认为不会使用也不需要编译的类型。GWT2.0还承诺提供更快、更方便和更可预见的布局。标准模式提供了新的功能，包括基于约束（constraint-based）的布局。在GWT2.0中还将有一个更新的控制面板。
2.0版本将GWT向前带动了一大步，为开发者和用户提高了性能。虽然不是官方的，但2.0也许还带来了新的基于XML的标记语言来定义布局。我的猜测是，语法将接近HTML 。希望新的版本能够吸引更多的GWT开发者，并希望有更多的部件库和扩展。（译/王玉磊）
