前言
跟前端篇一樣，現在記錄一下後臺應用端開發環境的搭建，針對的是java環境，現在分享給大家。
操作
1、下載和安裝Java
下載地址
JDK19和17
JDK8和11
下載dmg安裝即可，接著查詢安裝java的位置
➜ ~ /usr/libexec/java_home -V
Matching Java Virtual Machines (1):
19.0.2 (arm64) "Oracle Corporation" - "Java SE 19.0.2" /Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/Home
/Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/Home找到java安裝位置 之後，現在我們來編輯.bash_profile檔案,新增java環境
#java home
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/Home
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.儲存完之後，別忘了source ~/.bash_profile
2、下載和安裝Maven
點選官網下載地址下載
下載之後解壓到你想要儲存的地方即可。
儲存完之後，配置一下環境變數，再次編輯~/.bash_profile
#java home
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/Home
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.
# maven home
M3_HOME=/Users/justinzhang/Library/Maven/apache-maven-3.9.0
export PATH=$JAVA_HOME/bin:$M3_HOME/bin:$PATH:這樣就完成了Java和Maven的安裝，檢視Java和Maven的版本
➜ ~ java --version
java 19.0.2 2023-01-17
Java(TM) SE Runtime Environment (build 19.0.2+7-44)
Java HotSpot(TM) 64-Bit Server VM (build 19.0.2+7-44, mixed mode, sharing)
➜ ~ mvn -v
Apache Maven 3.9.0 (9b58d2bad23a66be161c4664ef21ce219c2c8584)
Maven home: /Users/justinzhang/Library/Maven/apache-maven-3.9.0
Java version: 19.0.2, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/Home
Default locale: zh_CN_#Hans, platform encoding: UTF-8
OS name: "mac os x", version: "13.2.1", arch: "aarch64", family: "mac"3、配置maven setting.xml檔案
先找到maven安裝路徑，我的路徑是
~/Library/apache-maven-3.5.0/conf/settings.xml找到之後編輯setting.xml檔案
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

這樣就配置好了Maven。
Idea配置
現在我們到idea中配置Java和Maven環境
總結
1、如果你使用的是壓縮包安裝方式安裝Java，只要放到指定目錄即可，然後配置Java環境，而使用dmg安裝方式安裝後的Java目錄，必須使用/usr/libexec/java_home -V才能獲取取。
2、安裝好maven之後記得配置setting.xml檔案。
3、Idea如果報Java相關錯，看看是不是沒有設定java版本
