一、IDEA简介

1、简介

官网介绍:Excel at enterprise, mobile and web development with Java, Scala and Groovy,with all the latest modern technologies and frameworks available out of thebox.
简明翻译:IntelliJ IDEA 主要用于支持 Java、Scala、Groovy 等语言的开发工具,同时具备支持目前主流的技术和框架,擅长于企业应用、移动应用和 Web 应用的开发

2、优势(相对eclipse而言)

① 强大的整合能力。比如:Git、Maven、Spring 等
② 提示功能的快速、便捷
③ 提示功能的范围广
④ 好用的快捷键和代码模板 private static final psf
⑤ 精准搜索
...

3、IDEA版本介绍

二、Windows安装

1. 安装前的准备

1.1 硬件要求(Hardware requirements)

 内存:2 GB RAM minimum, 4 GB RAM recommended
 硬盘:1.5 GB hard disk space + at least 1 GB for caches
 屏幕:1024x768 minimum screen resolution

1.2 软件要求(Software requirements)

Microsoft Windows 10/8/7/Vista/2003/XP (32 or 64 bit)

 JRE 1.8 is bundled with the IntelliJ IDEA distribution. You do not need to install Java
on your computer to run IntelliJ IDEA.
 A standalone JDK is required for Java development.

  1. 安装前的准备
    1.1 硬件要求(Hardware requirements)
     内存:2 GB RAM minimum, 4 GB RAM recommended
     硬盘:1.5 GB hard disk space + at least 1 GB for caches
     屏幕:1024x768 minimum screen resolution
    个人建议配置:内存 8G 或以上,CPU 最好 i5 以上,最好安装块固态硬盘(SSD),将 IDEA
    安装在固态硬盘上,这样流畅度会加快很多。
    1.2 软件要求(Software requirements)
    操作系统:Microsoft Windows 10/8/7/Vista/2003/XP (32 or 64 bit)
    软件环境:
     JRE 1.8 is bundled with the IntelliJ IDEA distribution. You do not need to install Java
    on your computer to run IntelliJ IDEA.
     A standalone JDK is required for Java development.

2、具体安装过程

步骤1.双击下载的IDEA软件
步骤2
步骤3
步骤4(根据自己的系统确认)
步骤5(选择不关联)
步骤6
步骤7

3、安装过程总结

从安装上来看,IntelliJ IDEA 对硬件的要求似乎不是很高。可是实际在开发中其实并不是这样的,因为 IntelliJ IDEA 执行时会有大量的缓存、索引文件,所以如果你正在使用 Eclipse / MyEclipse,想通过 IntelliJ IDEA 来解决计算机的卡、慢等问题,这基本上是不可能的,本质上你应该对自己的硬件设备进行升级

4、查看目录结构

IDEA安装后的目录结构图

bin:容器,执行文件和启动参数等
help:快捷键文档和其他帮助文档
jre64:64 位java 运行环境
lib:idea 依赖的类库
license:各个插件许可
plugin:插件

5、设置VM参数

-Xms128m,16 G 内存的机器可尝试设置为 -Xms512m
(设置初始的内存数,增加该值可以提高 Java 程序的启动速度。)
-Xmx750m,16 G 内存的机器可尝试设置为 -Xmx1500m
(设置最大内存数,提高该值,可以减少内存 Garage 收集的频率,提高程序性能)
-XX:ReservedCodeCacheSize=240m,16G 内存的机器可尝试设置为
-XX:ReservedCodeCacheSize=500m
(保留代码占用的内存容量)

6、查看设置目录结构

设置目录结构
6.1config目录
6.2system目录

三、启动后配置并激活

1.是否导入已有设置

2.激活
