我经常使用的一件事是设置断点，然后控制它的功能。(在我的上一份工作中，大多数人都使用Eclipse……我记得我很惊讶，没有人能在Eclipse中找到如何做到这一点。)

例如，可以让断点实际上不停止，而只是将消息记录到控制台。这意味着，我不必用“System.out.println(…)”乱写代码，然后重新编译。

VIM模拟器。这个插件在IDEA中编辑文件时提供了几乎完整的vi/vim/gvim仿真。 支持以下功能: 运动键 删除/修改 插入模式命令 标志着 寄存器 VIM撤销/重做 可视模式命令 一些Ex命令 Some:设置选项 用于搜索和搜索/替换的完整VIM正则表达式 宏 测量 命令行历史记录 搜索历史记录 跳转列表 VIM提供帮助

I can't see ever going back to any other ide because of this plugin.. Best of both worlds... Awesome!. that's what i was lacking in all IDEs.

IntelliJ具有从代码到jspx文档的智能感知和重构支持。

有很多事情是idea用更简单的方法解决的，或者没有等价的方法:

Autocomplete actions: Doing ctrl+shift+a you can call any idea action from the keyboard without remembering its key combination... Think about gnome-do or launchy in windows, and you've got the idea! Also, this feature supports CamelCasing abbreviations ;) Shelf: Lets you keep easily some pieces of code apart, and then review them through the diff viewer. Local history: It's far better managed, and simpler. SVN annotations and history: simpler to inspect, and also you can easily see the history only for such a part of a whole source file. Autocomplete everywhere, such as the evaluate expression and breakpoint condition windows. Maven integration... much, much simpler, and well integrated. Refactors much closer to the hand, such as loops insertion, wrapping/casting, renaming, and add variables. Find much powerful and well organized. Even in big projects Much stable to work with several branches of a big project at the same time (as a former bugfixer of 1.5Gb by branch sources, and the need to working in them simultaneously, idea shown its rock-solid capabilities) Cleaner and simpler interface... And, simpler to use only with the keyboard, letting apart the need of using the mouse for lots of simple taks, saving you time and giving you more focus on the code... where it matters!

现在，作为开源的…Idea的用户群将呈指数级增长。

一个非常有用的特性是能够部分构建Maven反应堆项目，以便只包括您需要的部分。

To make this a little clearer, consider the case of a collection of WAR files with a lot of common resources (e.g. JavaScript, Spring config files etc) being shared between them using the overlay technique. If you are working on some web page (running in Jetty) and want to change some of the overlay code that is held in a separate module then you'd normally expect to have to stop Jetty, run the Maven build, start Jetty again and continue. This is the case with Eclipse and just about every other IDE I've worked with. Not so in IntelliJ. Using the project settings you can define which facet of which module you would like to be included in a background build. Consequently you end up with a process that appears seamless. You make a change to pretty much any code in the project and instantly it is available after you refresh the browser.

非常简洁，而且非常快。

我无法想象在没有它的情况下，在像YUI这样的东西中编写一个返回到DWR/SpringMVC的前端。

Well, for me it's a thousand tiny things. Some of the macros, the GUI layout in general in Eclipse I find awful. I can't open multiple projects in different windows in Eclipse. I can open multiple projects, but then it's view based system swaps a bunch of things around on me when I switch files. IntelliJ's code inspections seem better. Its popup helpers to fix common issues is nice. Lots of simple usability things like the side bar where I can hover over a hot spot and it'll tell me every implementing subclass of a method or the method I'm implementing and from where.

每当我不得不使用Eclipse时，或者看到别人使用Eclipse时，他们似乎可以做我在IntelliJ中可以做的大部分事情，但它花费的时间更长，而且更笨重。
