从Maven POM打开一个项目。 只需选择“打开项目…”导航到你的顶级pom.xml，并按Enter:) NetBeans现在也有这个特性。

IntelliJ做了而Eclipse没有做的两件事对我来说非常有价值:

方法分隔符:方法之间那些模糊的灰色线条使代码更具可读性

文本抗锯齿:使代码在IDE中看起来很漂亮

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。

其他一些事情:

propagate parameters/exceptions when changing method signature, very handy for updating methods deep inside the call stack SQL code validation in the strings passed as arguments to jdbc calls (and the whole newly bundled language injection stuff) implemented in/overwritten in icons for interfaces & classes (and their methods) and the smart implementation navigation (Ctrl+Alt+Click or Ctrl+Alt+B) linking between the EJB 2.1 interfaces and bean classes (including refactoring support); old one, but still immensely valuable when working on older projects

IntelliJ具有从代码到jspx文档的智能感知和重构支持。

多得多的重构。
