IDEA的好处我就不说了，反正我个人觉得比Eclipse好用，看个人喜好。
下载地址：点击下载，有一个免费三十天的体验，后续要是想要继续使用需要激活，大家有条件的可以支持一下正版，网上也有许多激活码，这里就不讲激活了！
下载完成后，打开安装程序，选择适合直接电脑的版本（我的是64位），其他的暂时不用管，一路next，等待安装完成
配置IDEA：
选择IDEA的背景颜色，这里我选择黑色，也可以选择右边的白色，看个人喜好
选择安装插件，默认不安装任何插件，可按照自己的需求来安装。
附上一份IDEA激活码

推荐设置：
1.当前项目配置或全局配置
具体步骤：顶部工具栏 File - Other Settings - Porject Structure for New Projects
2.配置全局JDK
具体步骤：顶部工具栏 File - Other Settings - Structure for New Projects - SDK - 单击加号 - 选择JDK安装目录，同理也可在当前项目的Porject Structure为当前项目配置喜欢的JDK版本
3.Maven配置
具体步骤：顶部工具栏 File - Other Settings - Setting for New Projects - Build,Execution,Deployment - Build Tools - Maven
提示一下，Maven的本地仓库是系统自动生成的，通常在C盘用户目录下，在实际开发过程中推荐大家自己指定仓库地址，避免因为重装系统或被第三方工具清理而导致数据丢失。
配置好Maven后，在IDEA右侧，单击maven即可开始体验IDEA带来的快捷
4.Tomcat Server(当前项目配置)
具体步骤：顶部工具栏 File - Setting - Application Server
5.自动导包和智能移除
具体步骤：顶部导航栏 File - Other Settings - Setting for New Projects - Other Setting - Auto Import
6.取消大小写敏感
取消大小写敏感后，在编写代码时，代码自动提示将更加全面和丰富。
具体步骤： 顶部导航栏 File - Settings - Editor - General - Code Completion
7.设置字体类型和字体大小
默认的小字体大家可能看起来不舒服，会影响大家的编码体验，这里教大家如何配置字体。
具体步骤：顶部导航栏 File - Settings - Editor - Font
