My colleague has been recommending idea to me, saying that compared to eclipse is the Stone Age tool, I have always been able to use the eclipse as a tool, so I have been sticking to it, but I have seen the idea function, there are a few more attracted me, 1 can be full keyboard operation, 2 double bar display, 3 Multi-window display, 4 plug-in integration is more convenient than Eclipse, 5 interface is very beautiful. So it is decided to try the idea, if it is really so good, can improve efficiency why not?

Download Installation

IDEA has 2 versions, Community version and commercial version, the community version is free commercial version is charged (commercial version to provide more features than Community version).
"Official website address Download" "Baidu Cloud Disk Download 2016 Business Edition" (I still want to support the genuine (Purchase license link), just 499 knife/year for me or too expensive, so can only silently in the heart support, the way to crack can refer to http://idea.lanyus.com/ , offline hack best in a local license server, there are a lot of coverage jar files on the web, I tried a few did not succeed. Offline hack tutorial link) installation Although no eclipse as green Compression Direct decompression is OK, but the next step is not encountered any obstacle.

First Impressions

Start the page or see the familiar progress bar, but after the progress bar is gone, you can not go directly to the work page, but need to select an item first. Here is also an important difference between idea and Eclipse, Eclipse has the concept of workspace, a workspace inside can have multiple project,project between is relatively independent, and idea without workspace concept, The top of the list is Project,project can build several module, although the hierarchical relationship is two layers, but not exactly equal, idea of the module is more flexible than eclipse. Bury a pit behind and say. The first impression of idea is still very good.

HELLO World

For programmers, all sermons are not as good as a helloword on the screen. Before we start, we need to clear our brains and forget about the habits we used to eclipse, starting with 0 completely. Idea gives us almost all the possibilities for new projects, create new project.


Entering the next step is create project form template equivalent to selecting a template project, which can be skipped, entered project name with project location the project's name and the project storage path. Click Finish to complete a new project. srcRight Button new package Everything is still so familiar, create a familiar Helloword class. ctrl+F9compile and shift+F10 compile the run.

If you find that I'm not the same as your interface, it's because I modified the configuration to accommodate the difference between eclipse and idea, and later on how to configure Eclipse. Here to fill in the pit of project and workspace, just now the new project process is almost the same as the new project process in Eclipse, and there is not much difference. But many online say Eclipse's workspace is equivalent to project in idea. I don't think this is the way to understand, first of all we should be clear whether workspace or project is provided to us by the IDE to facilitate the management of the project, in Java there is no such concept, for Java only need to execute a similar command can be, Don't care how you manage the project,

So eclipse provides a way of workspace management, and workspace project is relatively independent, for example, when project compiles, it will be generated in its own bin directory. Eclipse prefers multiple project management, and Idea prefers the management of a single project, and the relationship between module and project in project is a attribution relationship. But Eclipse workspace and project don't have this concept, but the module in idea is in project, and Idea's module is more like the concept of module in Maven, Multiple module is just a different layer of project, but the idea of the module can also be done in a similar independent, the module can also have no dependencies, so it feels like project in Eclipse is similar, But this is not the idea of the original design, there is a point to reflect the relationship between project and module is the output path in idea, all the module output path under Project is the Project/out/production directory, So it's not recommended that you put multiple projects in one project as a different module to manage, but you can open ideas.

This is my tool!

The idea was pretty, but it was too far ahead for me, who used to be a spoiled eclipse. So let it get used to it.

Open Configuration Management

First of all remember this shortcut key ctrl+alt+s , click to know, settings out, with the previous eclipse in the window->Preferences same, configuration items, but most of us do not use.

Modify Theme Style

Idea gives us three kinds of themes, DARCLA black style is too high, I still change back to the default IntelliJ bar,--- ctrl+alt+s appearance&behacior appearancetheme

code hint key

alt+/In eclipse, this key can be said to be a divine key, but in idea it does not work, idea inside the code hint shortcut key is CTRL + SPACE (very familiar, and switch keyboard shortcut key conflict changed to our familiar alt+/bar)
ctrl+alt+sThe keymap mainmenu->code->completion original CTRL + Space is deleted and the alt+/is deleted, and then add alt+/save OK.

code font is not good to see the font size is too small?

Looking at the font of Eclipse, looking at the courier font of the idea code is too uncomfortable, and the font size is too small,--look is ctrl+alt+s edit color&fonts font(这里需要新建一个，字体courier size14) not much better. We also console font changed the following console font by the way.

Show Line Numbers

The line number is definitely not less, but idea is not as easy as Eclipse. Right-click Show lines Number,idea also need---- ctrl+alt+s editor general appearanceshow line numbers

double-column display code

This really is eclipse can not compare, to write code really is too practical. Operation is very simple, experience a bit but no sublime text is easy to use. But it's good, and the window can be taken out, which is beyond the reach of Eclipse.

let Idea go first .

Maven
The MAVEN plugin has been integrated in idea, does not need to be downloaded again, can be used almost without modifying the configuration, but we are still accustomed to modify the version of Maven, to ensure that we do not appear in the process because of the version caused by the problem.

Version Control
Whether you're using SVN, git, or GitHub to get started quickly in idea, there are a variety of version control plugins built into idea.

First download SLIKSVN (you can not download the SVN tool, directly using the idea of the SVN tool, I encountered the first time in use SVN commit can not be submitted, so it is recommended to download the SVN tool) after the installation is complete, configureuser command line clientSvn.exe's path, like mine.D:\Work\SlikSVN\bin\svn.exe
git needs to install Git's client first
Windows git version point I download (msysgit link) This download if there is a problem, provide a Baidu cloud point I download (Baidu Cloud link) 2.7.4
After the installation is complete, modify the Ideagit configuration:

You can use version control as easily as eclipse.
(Version control has a configuration that is recommended to tick on:Show directories with changed descendantsWith the eclipse of the effect is the same, if the file is modified, then the long layer of the file all the directories have become the modified identity)
compiling a Web project
In fact, the idea that all the third-party operation of the project is basically the same, such as we use MAVEN to compile the project, before in eclipse need to right-clickrun asThe parameters of Maven can be configured to run, similar to the idea.

And then the configuration of eclipse is almost exactly the same, the configuration of the boot name before eclipse can not be duplicate, there is no limit, and then select the running project, execute the command.

Runtime only need to select Run Configurationshift+F10
run the Web project
Tomcat
First you need to download and install Tomcat. Download tomcat, configure boot configuration after installing Tomcat, 1 Add a Tomcat boot configuration 2 configuration TOMCAT3 Select Tomcat Security Directory 4 Configure startup name 5 tick off start auto start browser

6 Switch to Deployment and add the project we want to deploy to Tomcat.

Start the Tomcat OK deployment complete.

Let idea help you, God .

Idea has super many shortcut keys can be convenient for us to use, this is a list of shortcut keys are interested to print out, more try to use the shortcut key operation.
