IntelliJ IDEA 2018.3.6 & 2019.2.2 & 2021.3.4 安装破解 与基本使用

1. 官网下载:

https://www.jetbrains.com/idea/download/other.html

选择 旗舰版IntelliJ IDEA Ultimate(收费版)，它的功能比社区版Community(免费)要多很多

我这里下载的是旗舰版 2018.3.6 for Windows (exe)

安装下载的包，全部默认下一步下一步即可，注意先不要启动该软件.

破解包下载地址 

 

 用这款开发工具开发软件不用 Ctrl+S保存 它会自动保存代码

 

2. 将破解包拷贝到IDEA安装目录的bin下

 

 

 编辑bin目录下的文件 idea.exe.vmoptions 和 idea64.exe.vmoptions 末尾追加

-javaagent:../bin/JetbrainsIdesCrack-4.2-release-sha1-jfiasf2134123n12342313.jar 这个字符串

 

 

将 idea64.exe 发送到桌面快捷方式

启动 idea64.exe， 选择不导入任何设置，跳过剩下的和选择默认，接着

在进入出现有active code选择界面的时候 写入下面注册代码：（到2099-12-31到期）

 ==============================================华丽的分割线=================================================

1. 启动加载的时候就能看到已经注册到了 2099.12.31

 

============================+++++++++简单的基本常用设置++++++++==========================================

==> 设置字体: Editor--Font: 我这里字体大小选择16， 字体选择 Consolas

 ==> 设置编码: Editor--File Encodings: 这里将所有的设置为UTF-8

根本上解决编码问题：

 ==>  编辑安装目录下的 C:\Program Files\JetBrains\IntelliJ IDEA 2018.3.6\bin\idea64.exe.vmoptions 和 idea.exe.vmoptions 

　　增加 -Dfile.encoding=utf-8

 

 ==>  对引入的web项目的web容器设置 idea server编码。在菜单栏找到”run->editconfigration” 找到”server”选项卡 设置 vm option为 -Dfile.encoding=utf-8

 JavaScript ES6语法支持

设置IDEA自动导入包

File-->Settings-->Editor-->General-->Auto Import

 勾选标注第1个选项，IntelliJ IDEA 将在我们抒写代码的时候自动帮我们导入需要用到的包。但是对于那些同名的包，还是需要手动 Alt + Enter 进行手动导入的

 勾选标注 第2个选项，IntelliJ IDEA 将在我们抒写代码的时候自动帮我们优化导入的包，比如自动去掉一些没有用到的包。

 

==> 快捷键设置。。。

设置 自动补全快捷键 Keymap-->设置那个小图标，Duplicate... Default copy，然后在编辑
* Main menu --> Code --> Completion --> Basic 双击右边快捷键 删除原来的 Ctrl +空格
* 再双击打开，添加快捷键 输入 Alt + / ,保存 ，与下面的冲突不用管 按照提示删除即可

 设置 自动补全快捷键 Keymap-->设置那个小图标，Duplicate... Default copy，然后在编辑
* Main menu --> Code --> Generate...  双击右边快捷键 删除原来的Alt+Insert
* 再双击打开，添加快捷键 输入 Alt + I ,保存 

 ==> 设置 自己的Maven...

maven项目有时候不小心关闭了(没有了maven图标)？

pom.xml 右键--> Maven --> Unignore 即可恢复.

 

 安装Vue插件

解决IDEA无法安装插件的问题

如果按照此法还无法解决，建议通过浏览器访问 https://plugins.jetbrains.com/  然后搜索下载离线的插件(必须是适合你所使用的idea版本的插件才行,如我这个就必须选择 2018.3)。

最后 Settings--> Plugins -->设置图标里面点击 INstall Plugin from Disk...

 

idea 安装lombok插件,,即可消除get set log这些不识别问题

 

 

 

 IDEA显示工具栏：  在打开IDEA项目后，点击菜单上的View-->勾上 ToolBar  Tool Buttons

 

Spring的 @Autowired 使用后  当类名与属性名不一致时会出现红色的波浪线但不影响使用，如果嫌碍事想去除，

则如下图那样 在IDEA中右下角点击红圈圈起来的图标，再将滑块由最右边滑动到中间 即可。

=============================================华丽的分割线==========================================================

 

控制台显示出来 Alt+4
隐藏的话，控制台右上角的 - 符号

 

常用的一些快捷键
 Alt + Enter , 导入包自动修正代码; 重要的
 Ctrl + Y , 删除光标所在行;
Ctrl + D , 复制光标所在行并插入到光标位置下面;
Ctrl + Alt + L , 格式化代码; 重要的
Ctrl + / , 单行注释;
Ctrl + Shift + / , 多行注释;
Alt + Ins , 自动生成代码 如 get set toString等方法
Alt + Shift + 上下箭头 , 移动当前代码行

Ctrl + Shift + U  选中的内容 大小写转化

两次 Shift 搜索

Ctrl + H ，打开当前窗口类的继承结构 

Ctrl + Alt +B  查找接口有哪些实现类

Ctrl + P  方法参数提示

 Ctrl + Alt + O ，消除无效引用

 Ctrl +Alt + T ,  选中代码后，可以被surround with包裹

 Ctrl +Alt + 左箭头，一层层退到方法的调用者

 Ctrl + Shift + F ，全局搜索内容(类似于Eclipse的Ctrl+H)，不过它通常被输入法占用了，可以改输入法，也可以改IDEA快捷键，我这里改的是IDEA快捷键为  Ctrl + Shift + Q 

 ==》 Keymap-->设置那个小图标，Duplicate... Default copy，然后在编辑
* Main menu --> Edit -->Find...Find in Path  双击右边快捷键 删除原来的
* 再双击打开，添加快捷键 输入 Ctrl + Shift + Q ,保存 

 

 

idea如何关闭让人眼花的mybatis xml文件警告

①去掉 No data sources configure 警告 

• Settings ⇒ Editor ⇒ Inspections ⇒ SQL ⇒ No data sources configure。
• 取消勾选，去掉这个检查，然后点击 OK 按钮即可

②去掉 SQL dialect is not configured 警告

• Settings ⇒ Editor ⇒ Inspections ⇒ SQL ⇒ SQL dialect detection。
• 取消勾选，去掉这个检查，然后点击 OK 按钮即可。

 

idea大量test做数据迁移产生日志导致硬盘空间不足

报 Low disk space on a Intelij IDEA system directory partition (磁盘空间不足)

 

解决办法1:  清理掉产生的大量日志文件 如我的在  C:\Users\Administrator\AppData\Local\Temp 

                                                                              C:\Users\Administrator\.IntelliJIdea2018.3\system\testHistory\**\*

解决办法2:  在idea的安装目录下找到idea64.exe.vmoptions文件：追加 -Didea.no.system.path.space.monitoring=true

 

 

项目的关闭与重新打开

 File -- Close Project 关闭 ，双击左侧的记录可以打开，若不小心删除了左侧的记录呢，此时需要 点击 Open 找到目录上有小黑点的那个即可

如何在当前项目下，在新建一个module呢? File -> New Modele... 比如我这里新建了一个 demo1
如何在项目中删除 demo1呢? 选中demo1，右键 找到 Remove Module（快捷键是 Delete键），这个demo1在硬盘上还存在着
如何导入一个 Module？ File -> Project Structure... -> 打开窗口的左侧选中着Module，点击 + 符号，选择 import Module，
选择好我们刚才的demo1之后， 一路next 最后Finish即可

 

 

编译时报错不能使用diamond预算符

报错信息如下：Error:(16, 60) java: -source 1.5 中不支持 diamond 运算符(请使用 -source 7 或更高版本以启用 diamond 运算符)

解决方法： 1 选择 File --> project Structure --> Modules，选择项目修改 “Sources” 选项卡下的 “Language level” 及 “Dependencies”选项卡下的 “Module SDK

2 修改Java Compiler

File --> Settings --> Build,Execution,Deployment --> Compiler --> java Compiler

2019.2.2版本的破解 （参考了文章: https://www.jiweichengzhu.com/article/93afbed1245d4ee69b82ed1b067f48a4 ）

 

破解包下载地址

 

1.  安装完成之后，将破解包jetbrains-agent.jar拷贝到 C:\Program Files\JetBrains\IntelliJ IDEA 2019.2.2\bin安装目录下

2.  进入目录 C:\Users\Administrator\.IntelliJIdea2019.2\config\ 下编辑文件 idea64.exe.vmoptions (注意与2018版本的不同) ，增加下面内容

若目录不存在，则可以先启动一次idea64.exe, 会帮我们生成这个目录，若相应的位置没有 idea64.exe.vmoptions，就把bin路径下的这个文件拷贝一份，然后添加如下行:

-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2019.2.2\bin\jetbrains-agent.jar

3. 打开idea64.exe ，输入激活码（以下三个任选一种一个）

project与module

idea的maven理念

在Idea中，没有工作空间的概念，每一个Project就是一个独立的文件夹，也是一个独立的窗口。然后我们可以在Project中创建多个Module。

是不是感觉与maven的项目结构完全一致？

说对了，idea就是完全贯彻了maven的理念。

小技巧

熟悉eclipse的同学会觉得很不方便，无法在一个界面中创建很多的工程。

不过有一个取巧的办法：我们可以创建一个empty的工程

但是接下来，就不要再新建Project了，而是新建Module，Module就类似原来的工程的概念

 

打开springboot的run dashboard

先看下run dashboard是什么：

可以看到，这里可以同时显示多个springboot项目，非常方便。

默认情况下，idea的run dashboard是关闭的，当检测到你有多个springboot项目时会弹出提示框，询问是否打开。

 

如果我们想要自己打开，需要修改配置。在你的idea的项目目录中，有一个.idea目录 其中，有一个workspace.xml

打开，搜索 Rundashboard，找到下面这段

 

然后在Component中添加下面的内容

　　<option name="configurationTypes">
　　　　<set>
　　　　<option value="SpringBootApplicationConfigurationType" />
　　　　</set>
　　</option>

 

修改后的结果

 

 

修改后的效果：

 

附上 IDEA2020.3.4版的激活方式  https://www.openwebsite.cn/archives/746

大致步骤如下（亲测有效）：

1， 先试用30天

2，安装插件 BetterIntelliJ.zip （前面有介绍如何安装本地插件到IDEA中）

3，重启IEDA

4，Help--> Register 添加激活码
