[Java-01] Mac-Maven-VSCode-配置&編譯

Mac-Maven-VSCode-配置&編譯

1: mac 安裝java 1.8

參考鏈接：https://www.jianshu.com/p/5b5dcbf3f7d8

• 下載jdk
  http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

• .bash_profile 配置環境變量

編輯java全局路徑
export JAVA_HOME=$(/usr/libexec/java_home)
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

• 打開終端、測試

#  java -version
bmwdeMacBook-Pro:~ bmw$ java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
bmwdeMacBook-Pro:~ bmw$ 

2. 下載maven

參考鏈接：https://blog.csdn.net/weixin_43974907/article/details/107916386

• apache 官網
  https://maven.apache.org/download.cgi
  

• 配置Maven配置環境

• 將下載的apache-maven-3.8.2 解壓在mac 目錄下

# /Users/bmw/apache-maven-3.8.2 為解壓目錄路徑PATH
export MAVEN_HOME=/Users/bmw/apache-maven-3.8.2
export PATH=$MAVEN_HOME/bin:$PATH

• 打開終端，驗證maven

# mvn -v
bmwdeMacBook-Pro:~ bmw$ mvn -v
Apache Maven 3.8.2 (ea98e05a04480131370aa0c110b8c54cf726c06f)
Maven home: /Users/bmw/apache-maven-3.8.2
Java version: 1.8.0_181, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.16", arch: "x86_64", family: "mac"

3. 配置VSCode

參考鏈接: http://www.littleblog.cn/javaee/7089.html

• 下載plugin
  • Maven for Java
  • Java Extension Pack
  • Spring Boot Extension Pack
  • Language Support for Java(TM) by Red Hat

# 下載完基本上這些插件都會存在.
Language Support for Java(TM) by Red Hat
Debugger for Java
Java Test Runner
Maven for Java

• 配置vscode 中 java_home 地址

#  步驟
1：打開設置(command + ,)，搜索maven
2: 選擇 Extension -> Maven for Java -> Edit in setting.json
3: 填寫 "java.home": "/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home"

# mac java.home 地址獲取:
bmwdeMacBook-Pro:~ bmw$ /usr/libexec/java_home
/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home

4. 首次使用VSCode創建第一個java項目

• 1: cmd+shift+p 輸入maven
• 2: 選擇Maven: create maven project
• 3: 選擇maven-qrchetype-quickstart快速創建
• 4: 創建過程中需要輸入groupid, artifactid, version, package

groupid 一般分為多個段，這里我只說兩段，第一段為域，第二段為公司名稱, 雖然產生的項目結構文件與groupId無關，但是大家公認的規范是填寫項目包名，如com.xx.testArchetypeGenerate（公司網址反寫+項目名）
artifactid 填寫你負責的模塊名，如項目名-模塊名
version 版本號
package 填寫你創建的類所在的包名

例如:
groupid: com.bmw.createjavademo01
artifactid: createjavademo01-login
version: 1.0.0
package: 默認回車

• 5: 創建完成

5: 開始build java 項目

• 1: 選擇launch.json 配置

// 如：
{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "Debug(Launch) - Current File",
            "request": "launch",
            "mainClass": "${file}"
        },
        {
            "type": "java",
            "name": "Debug(Launch)-App<target>",
            "request": "launch",
            "mainClass": "target.App",
            "projectName": "target"
        }
    ]
}

• 2: build
  • 按F5或點擊run試試看
    如：
    bmwdeMacBook-Pro:createjavademo01-login bmw$ cd /Users/bmw/Desktop/java-demo/createjavademo01-login ; /usr/bin/env /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home/bin/java -agentlib:jdwp=transport=dt_socket,server=n,suspend=y,address=localhost:57198 -Dfile.encoding=UTF-8 -cp /Users/bmw/Desktop/java-demo/createjavademo01-login/target/classes com.bmw.createjavademo01.App
    Hello World!
