注意：可能会报Your activation code could not be validated (error 1653219)错误
解决方式：在host文件添加 0.0.0.0 https://account.jetbrains.com:443，第一种方式的那两个就不再需要了
3）IDEA配置
3.1 设置IDEA主题
下载喜欢的主题，找到File>>import settings，导入之后重启生效
3.2 设置IDEA字体大小
3.3 设置快捷方式为Eclipse
3.4 设置IDEA不区分大小写
3.5 设置IDEA自动导包（目前版本的设置，去除包只适合当前项目，所以下次还要设置）
3.6 设置IDEA的代码页多行显示
3.7 设置IDEA方法之间一条线分隔
3.8 设置IDEA鼠标滚动改变字体大小
3.9 设置IDEA忽略某些文件
3.10 设置IDEA类注释模板
3.11 设置IDEA鼠标悬停效果
3.12 设置IDEA里面的xml模板
4）IDEA工具说明
4.1 项目结构
第一个，点击之后，就会在左侧的文件一栏里，定位到你当前打开的文件的位置，找文件，定位文件位置用的非常多。
第二个，合并所有目录，这个在你打开太多目录的时候，一点击之后，就会把目录全部折叠起来。
第三个，项目目录结构展示的设置，比较特殊，
4.2 侧边栏
4.3 代码警告级别
5）项目热部署
5.1 安装JRebel插件
注意：jrebel激活之后（激活方式：https://tools.hexianwei.com/#/tools/jrebel）默认是联网使用的 , 在该模式下 , jrebel会一直联网监测激活信息 ，所以要调为离线使用的，点击JRebel面板下的work online防止联网检查，安装启动之后在工具栏会出现新的启动方式
5.2 设置项目热部署
5.3 勾选需要使用热部署的模块
通过view>>tool windows>>JRebel勾选相应模块即可
虽然已经可以通过maven依赖解决，但是生产环境不一定需要，所以开发时使用即可，
可以通过快捷键设置项目热部署：
ctrl+shift+alt+/：选择第一个Registry，然后勾选
如果失效，则打开配置，设置如下即可
在IDEA中，打开File>>>ImportSettings可以导入配置，如IDEA的配置文件、主题jar包等；
在IDEA中，打开File>>>ExportSettings可以导出配置，主要可以导出IDEA所有配置信息。
