本文介绍的是绿色版安装,安装之前请参考Selecting the JDK version the IDE will run under和zip安装包下面的Install-Windows-zip.txt
一.下载最新版ideaIU-14.1.3.zip并解压到你想要安装的目录.下载完最好验证一下sha256
至于下载地址:
如果想得到稳定的发行版:到https://www.jetbrains.com/idea/download/点击Download Ultimate,发觉下载的是exe,只要将下载地址的exe改为zip(到了IDEA15.0.1+应改为win.zip)就行.
如果想得到早期访问预览版(EAP):https://confluence.jetbrains.com/display/IDEADEV/EAP,下一步就看你了.
二.配置JDK.通过以上的参考,我配置64位的方法:复制64位jdk1.8到安装目录,并重命名为jre64.
实际上除了jre目录,lib目录和lib目录下面的tools.jar,这个jre64的其它目录与文件都可以删除
三.注册.双击bin\idea64.exe来运行.输入以下Licence
User or company name:
xiejx618
License key:
84293-Y5CGU-1W8NJ-CDDM3-QAN66-VCQP5
至于licence怎么得到,可以参考http://www.rover12421.com/2014/11/18/jetbrains-keggen.html
四.根据自己偏好配置插件
1.插件配置:
Java Frameworks:J2EE,Hibernate,Spring
Build Tools:Maven,Gradle
Web Development:HTML,CSS,LESS,JavaScript
Version Controls:Disable
Test Tools:JUnit
Application Servers:Disable
Clouds:Disable
Swing:Disable
Android:Enable
Database Tool:Enable
Other Tools:Bytecode Viewer
Plugin Development:Disable
2.设置配置.
a.file encodings:ide encoding和project encoding,properties files都设为utf-8,勾上Transparent native-to-ascii conversion
b.maven,svn,git设置.maven设置maven home directory;svn设置svn命令路径,svn配置目录;git命令路径;
c..show line:勾上show line numbers和show whitespaces
d.updates:设为不更新.
e.去掉reopen last project on startup的勾
idea的属性文件UTF-8编码详细设置
输入中文,通过Resource Bundle Editor自动将文字转为Unicode编码.
1.ctrl+alt+s打开Setting,File Encoding->Default encoding for properties file设为UTF-8,勾上右边的Transparent native-to-ascii conversion
2.通过Resource Bundle Editor打开某个属性文件,输入文字,这时编辑器会自动透明帮你转换.值得提醒的是:在Resource Bundle Editor看不到转化效果(也就是你输入中文,Resource Bundle Editor还是显示中文,实际上文件已经做了转换,通过记事本打开看就知道了)

常见问题:
maven多模块项目时，在子模块运行的Working Directory问题.运行java应用方法Working Directory被默认设为项目的根目录而不是模块的根目录.
比如在
project-parent
+-module1
+- src
+-main
+-java
+-org
+-exam
\-Test.java
\-text.txt
\-pom.xml
\-pom.xml
Test.java
package org.exam;
import java.io.File;
public class Test {
public static void main(String[] args) {
System.out.println("result = " + new File("test.txt").exists());
}
}

解决办法:In Run->Edit configuration->Defaults->JUnit->Working directory set the value $MODULE_DIR$ and Intellij will set the relative path in all junits just like Maven.
在对应的运行配置设置Working directory为$MODULE_DIR$，运行上面的测试，发现相对路径就会正确
