Idea of [developing killer]

Rapid delivery must have good tools to improve development efficiency , This article introduces the development of heavy killer IntelliJ IDEA. Including those we have developed for many years Bottom pressing tool It's all open , The following is the welfare time ~

• win+linux Dual system , At the same time, it supports sandbox repeated verification ！
• Idea Common configurations and skills sharing
• Idea Integrate docker, Fully automatic publishing 、 Graphical management application ！

One 、Win10 Development machine installation preparation

If a worker wants to do a good job, he must sharpen his tools first , Start idea Before using , It is also necessary to optimize the local development machine , Provided here win+linux The perfect solution of dual system and sandbox And other pre supporting software ！

win10 achieve win+linux Dual system , And the experimental environment with sandbox ！

The operating system comes with cmd It's relatively weak , Sometimes we need multiple windows 、 Run the command in the specified directory 、 image linux Integrate or switch many different shell It's hard to do it when . This product is launched by Microsoft with a low profile , Not included , In the Microsoft app store and github You can download freely on 、 Free trial , Here is a big recommendation ！

Windows Terminal Official download address ：  Microsoft Store  or   GitHub

When using , In any directory , Right click to see open in terminal, However, the goose is even better , Support on the command line ssh、 And bring it with you Ubuntu etc. linux System , Let our development learning connect seamlessly ！

After restart, we download it from the app store ubuntu, So you can do it win10 Swim down java The world ~

You need to set a password for the first time , Then you can use the application menu , or terminal Open directly in , If you don't like it, you can also download other versions or other distributions at will , Such as fedora、opensuse wait

The sandbox with its own program is opened on the top , Let's try all kinds of tools at will without psychological burden ！ After the sandbox is opened 【 Start 】 Can be found in the menu , Very comfortable to use , Turn off automatic cleaning after use .

The configuration you may need is memory amplification 、 Mount Host Directory , Reference code is provided here

Log in and copy

<!--  Save as XXX.wsb file , Here is the memory configuration , The host machine 、 Sandbox directory for reference  -->
<Configuration>
	<MemoryInMB>8196</MemoryInMB>

			<HostFolder>G:\ development tool </HostFolder>
			<SandboxFolder>c:\ development tool </SandboxFolder>
			<ReadOnly>false</ReadOnly>
		</MappedFolder>
	</MappedFolders>

jdk Installation configuration

Download from official website 、 install , routine 1.8 The version of is enough , Suggest JAVA Class tools are installed in the same directory , Such as d:\java\.

When JDK、JRE After installation , The environment variable configuration is supplemented here , In this way, we can run directly in many places cmd 了 ~

Environment variable configuration , windows System settings , My computer -》 Right click Properties -》 Advanced settings -》 environment variable

The above operations are mainly used to run directly from the command line java、javac、jar、mvm Wait for the order

Maven Installation configuration

Download and install ： Apache Maven Download from the official website zip package , Unzip to D:/JAVA/ Next , And configure environment variables AVEN_HOME, Add to PATH in

test ： Verify that the command line is available

To configure : To configure Aliyuan accelerates 、 Local warehouse cache , hinder idea Applying this configuration can Unified ！

Tomcat 8.5 Installation configuration

take  apache-maven-3.8.6-bin.zip Download and unzip to D:/java

test , double-click tomcat/bin/startup.bat, Check whether the command line reports an error , Whether the browser can normally access 8080 port , If there is a conflict , modify conf The configuration file , Replace 8080 For other ports

Two 、IntelliJ Idea install 、 To configure

idea As a commercial software , With many third-party tools , However, it is suggested that we prepare by ourselves , If there are better tools in the future, we can smoothly switch , Many similar events have happened , For example, it was very popular before JBuild、eclipse、MyEclipse wait

Provided on the official website 30 Day trial enterprise 、 Community Edition , You can download tests , Download IntelliJ IDEA

The installation path is unified in the same directory for easy management , Remember to switch the pre installed JDK~

idea Comment template

Class template （ When new ）
Set the path ：File-Settings-Editor-File and Code Templates-Incudes-File Header Use ready-made , New if not , The contents are as follows

Log in and copy

Method template （ Set carriage return auto generation ）

Set the path ：File-Settings-Editor-Live Templates Next add a new template group , Name customization JavaTemplateGroup, This template group creates a new template , Set up Abbreviation Configure to *,option Under the expand Set to carriage return generation , Three of these parameters are as follows ：

• return, methodReturnType()
• date, date(“Y-MM-d, E, H:m”) This query comes from GG, Parameter empty only has date
• param as follows ：

Log in and copy

groovyScript("def result=''; def params=\"${_1}\".replaceAll('[\\\\[|\\\\]|\\\\s]', '').split(',').toList(); for(i = 0; i < params.size(); i++) {result+='* @param: ' + params[i] + ((i < params.size() - 1) ? '\\n ' : '')};return result", methodParameters())

• The template is as follows , Be careful , want Missing a slash

Log in and copy

import org.springframework.web.bind.annotation.GetMapping;  
import org.springframework.web.bind.annotation.RestController;

highlight ！IDEA And Docker Integration of remote servers

There are many detours here , It's using idea2021 Version of , I can't live or die , It was used 2022.1 The latest version of is OK 了 ~

Step one ： Docker The server is open 2375 port

ssh Configure on the server 、 Restart the service and verify

Log in and copy

vim /lib/systemd/system/docker.service# modify ExecStart This line 
ExecStart=/usr/bin/dockerd  -H tcp://0.0.0.0:2375  -H unix:///var/run/docker.sock


systemctl daemon-reload
systemctl restart docker

curl localhost:2375/info  // If you can respond normally json The message represents the success of opening

Step two ： Idea To configure Docker

In this step, you must see the prompt at the bottom that the connection is successful ！

Step three ： Modify the project pom To configure

add to dockerFile, Agreed specifications , The documents are stored in java Source code level directory

Log in and copy

FROM java:8  
COPY demo.jar /usr/local/  
WORKDIR /usr/local/  
CMD java -jar demo.jar

This implementation maven Panel clean、package operation , Deo gratias , I saw it docker Layered compilation ！

Step four ： Joint commissioning and test
stay idea below service in , find docker, If it doesn't start, click , Find what we compiled and uploaded image, Right click to create a container , This automatically generates Run configuration

Set the image name for the boot configuration 、 Container name , And add operating parameters , You can also preview , The following can also be set before startup maven Recompile and package , This completes Automation ！

After modifying the code , Re execution , You can see that the page has changed in time

At the end

idea It's a good tool , It's easy to see docker journal 、 Graphical maintenance , Very good !

Interaction with you is the driving force of my continuous creation ！【 One button three links is the ladder of human progress ！】
