I have a soft spot for VS Code. So I tried to build a Spring Boot development environment in VS Code on the Windows platform.
Necessary preparation
Spring Boot belongs to the Java framework and is a necessary condition for Java development. It must be installed first:
Install JDK
In this step, we can download the latest JDK installation directly on the Oracle official website:
Then double-click to install, after several next steps, complete the installation.
After the installation is complete, remember to configure the environment variables (I don't know why this environment variable of the JDK has not been automatically configured):
After configuring the environment variables, in the console, execute the command to check whether the installation is successful:
java -version
If you execute the above command, you can see the version number of Java successfully. Congratulations, the installation of Java JDK is successful.
Install maven
As the most popular project management tool in the Java industry, maven is also a daily necessity in Spring Boot development and needs to be downloaded.
We can choose the pre-compiled zip binary package here:
After opening the maven package, unzip it, find a location you like, and save it. Remember where you saved it, because we need to configure maven-related parameters in VS Code later.
maven
Install VS Code
Install the necessary plugins
Now open VS Code and install the following two plugins:
Java Extension Pack
Spring Boot Extension Pack
Configure maven options
Development is not yet possible, and some configuration needs to be done, don’t worry:
In order to improve the access speed of maven, we modify its source to aliyun maven:
The partial code in maven's settings.xml is as follows:
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
<mirrorOf>central</mirrorOf>
</mirror>
Well, here, our environment configuration is complete. Restart VS Code, and you can start development in the next step!
Create a test demo project
Start VS Code again, press Ctrl + Shift + P shortcut, call up the command, enter spring, and then create a new maven project:
Note: After entering Group Id, press Enter
Hit enter
Hit enter
Introduction to dependency package functions:
Spring Boot DevTools: 支持代码修改热更新，无需重启
Spring Web: 集成Tomcat SpringMVC
Lombok: 智能生成 setter getter toString等
Thymeleaf: 模板引擎
Wait for the project to be created, and then open:
If you see the source code structure above, congratulations, you have succeeded!
Add test business code
The project is successfully created, next, add the test business code:
code show as below:
package alien.learn.ademo.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TestControllerRest{
@RequestMapping("/test")
public String testRest(){
return "欢迎使用VS Code 和 Spring Boot";
}
}
Add another html template:
Code:
<!DOCTYPE html>
<html lang="ch">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>主页</title>
</head>
<body>
<h1>Spring Boot Page!</h1>
<p th:text="${title}"></p>
</body>
</html>
Add another Controller:
Code:
package alien.learn.ademo.controller;
import java.util.HashMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.stereotype.Controller;
@Controller
public class TestController{
@RequestMapping("/hello")
public String getPage(HashMap<String, String> map){
map.put("title", "欢迎来到Spring Boot!");
return "/index";
}
}
Then F5 debugging service:
Then try to access the service in the browser:
Visit hello again:
If you got here successfully, congratulations, you have experienced the basic process of Spring Boot development in VS Code! Start your pleasant development journey.
