VSCode (Visual Studio Code) 配置java环境(Win10)

Visual Studio Code 版本为1.60.2

---

1、下载VSCode (Visual Studio Code)

​ 地址： https://code.visualstudio.com/

2、修改应用商店插件下载目录

​ 目的是节省C盘空间

2.1、创建插件文件夹并将C:\Users\用户.vscode\extensions下的文件拷贝到此目录下

2.2、建立链接

mklink /D  "C:\Users\*****\.vscode\extensions" "D:\plugins\vscode\extensions"

3、可选插件下载

# 1、Visual Studio Code设置成中文
Chinese (Simplified) Language Pack for Visual Studio Code 
# 2、本地产生一个.history文件夹(管理本地文件修改历史记录)
Local History
# 3、代码管理Gitee仓库
Gitee
# 4、简化POJO
Lombok Annotations Support for VS Code
# 5、自动修复一些 bug
Checkstyle for VS Code
# 6、按着 Ctrl 键点击 yml 属性可以自动跳转到对应的元文件定义里面
YAML Language Support by Red Hat
# 7、xml
XML Language Support by Red Hat
# 8、正则
any-rule

4、配置JAVA和MAVEN环境

4.1、安装JAVA扩展包

​ Extension Pack for Java

4.2、配置多个JDK

​ 打开settings.json配置jdk信息

# 指定您的语言服务器的执行环境(注意：虽然 Java 语言服务器需要 JDK 11 或更高版本才能运行，但这不是项目运行时的要求)
"java.home": "E:\\jdk\\java11\\jdk11",
# 指定项目执行环境的选项(运行时名称必须是以下之一：“J2SE-1.5”、“JavaSE-1.6”、“JavaSE-1.7”、“JavaSE-1.8”、“JavaSE-# # 9”、“JavaSE-10”、“JavaSE-11”、“ JavaSE-12”、“JavaSE-13”、“JavaSE-14”、“JavaSE-15”)
"java.configuration.runtimes": [
        {
            "name": "JavaSE-1.6",
            "path": "E:\\jdk\\java6\\jdk6"
        },
        {
            "name": "JavaSE-1.7",
            "path": "E:\\jdk\\java7\\jdk7"
        },
        {
            "name": "JavaSE-1.8",
            "path": "E:\\jdk\\jdk8",
            "default": true
        },
        {
            "name": "JavaSE-11",
            "path": "E:\\jdk\\java11\\jdk11",
        },
    ],

4.3、配置maven

​ 前提是安装Maven for Java 插件

# 指定所有mvn命令的默认选项。
"maven.executable.options": "E:\\maven\\apache-maven-3.6.3\\bin\\mvn.cmd",
# 指定settings.xml文件
"java.configuration.maven.userSettings": "E:\\maven\\apache-maven-3.6.3\\conf\\settings.xml",
# 自定义环境变量。在首次执行 Maven 之前，这些环境变量值将被添加到终端会话中
"maven.terminal.customEnv": [
        {
            "environmentVariable": "JAVA_HOME",
            "value": "E:\\jdk\\jdk8"
        }
    ],
# 如果此值为true,并且配置项java.home有值，则在创建新的终端窗口时，将环境变量JAVA_HOME设置为java.home的值
"maven.terminal.useJavaHome": true,

5、日常开发中的快捷键设置及说明

5.1、VSCode配置(settings.json文件)

# 显示底部状态栏
"workbench.statusBar.visible": true,

5.2、快捷键

# intelliSense 自动建议
editor.action.triggerSuggest
# 清除终端日志
workbench.action.terminal.clear
# 代码折叠
fold cell
# 代码展开
unfold cell
# 打开集成终端
Toggle Integrated Terminal
# 显示所有打开的文件
workbench.action.quickOpenNavigateNextInEditorPicker

6、创建Springboot项目验证

6.1、创建项目

pom.xml

HelloController.java

package com.vscode.springboottest.controller;

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

@RestController
public class HelloController {

    @GetMapping("/")
    public String hello() {
        return "Hello World!";
    }

}

application.yml

# 开发环境配置
server:
  # 服务器的HTTP端口，默认为8080
  port: 8080
  servlet:
    # 应用的访问路径
    context-path: /

6.2、运行
