Maven配置，下载的apache-maven-3.6.3-bin.zip 或者apache-maven-3.6.3-bin.tar.gz都可以
- 配置环境变量 MAVEN_HOME （E:\apache-maven-3.6.3\）
- 增加Path环境变量的目录：%MAVEN_HOME%\bin
#上面操作保存后，在新打开的CMD中测试mvn命令
C:\Users\Administrator>mvn -version

- 配置Java › Configuration › Maven: Global Settings ；Path to Maven's global settings.xml 为 E:\apache-maven-3.6.3\conf\settings.xml
- 配置Maven › Executable: Path 指定mvn可执行文件的绝对路径。当此值为空时，它会根据 maven.executable.preferMavenWrapper 的值尝试使用 mvn 或 mvnw 。 E:\apache-maven-3.6.3\bin\mvn
- 配置"java.home": "C:\Program Files\Java\jdk1.8.0_231",
问题Java 11 or more recent is required to run. Please download and install a recent JDK.
将Language Support for Java(TM) by Red Hat 降级到0.62.0以下，设置禁止自动更新
创建项目
在VS Code输入ctrl + shift + P命令，输入spring,选择Spring Initializr: Generate a Maven Project。
后面依次选择版本2.3.9-->java -- > 默认项目名称--> demo--jar等；在search for dependencies，选Spring Boot DevTools\Lombok\Spring Web\Thymeleaf（\MyBatis\MySQL 根据自己需要，这里不安装） , 然后选择selected 4 dependencies选项，选择目录即可。
安装依赖：(报错删除src\test\java\com\example\demo\DemoApplicatioTests.java后重试)
C:\Users\Administrator\Desktop\java_project>"E:\apache-maven-3.6.3\bin\mvn" install -f "c:\Users\Administrator\Desktop\java_project\demo\pom.xml"
#省略中间输出......

创建测试contraller
创建controller文件src\main\java\com\example\demo\controller\TestControllerRest.java
package com.example.demo.controller;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
@RestController
public class TestControllerRest {
@RequestMapping("/test")
public String testRest(){
return "Hello world";
}
}
创建src\resources\templates\index.html
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>
<body>
<h1>Spring Boot Page!</h1>
<p>th:text="${title}"</p>
</body>
</html>
创建src\main\java\com\example\demo\controller\TestController.java
package com.example.demo.controller;
import java.util.HashMap;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class TestController {
@RequestMapping("/hello")
public String getPage(HashMap<String,String> map){
map.put("title","欢迎来到springboot");
return "/index.html";
}
}
重新加载project目录，打开文件夹demo。运行spring项目，没用maven依赖在pom.xml中删除(如果无法运行注意vscode打开的目录，重启vscode)。
