前言跟前端篇一样，现在记录一下后台应用端开发环境的搭建，针对的是java环境，现在分享给大家。操作1、下载和安装Java下载地址JDK19和17JDK8和11下载dmg安装即可，接着查询安装java的位置? ~ /usr/libexec/java_home -VMatching 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安装位置 之后，现在我们来编辑.bash_profile文件,添加java环境#java homeJAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/Homeexport CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.保存完之后，别忘了source ~/.bash_profile2、下载和安装Maven点击官网下载地址下载下载之后解压到你想要保存的地方即可。保存完之后，配置一下环境变量，再次编辑~/.bash_profile#java homeJAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/Homeexport CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.# maven homeM3_HOME=/Users/justinzhang/Library/Maven/apache-maven-3.9.0export PATH=$JAVA_HOME/bin:$M3_HOME/bin:$PATH:这样就完成了Java和Maven的安装，查看Java和Maven的版本? ~ java --versionjava 19.0.2 2023-01-17Java(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 -vApache Maven 3.9.0 (9b58d2bad23a66be161c4664ef21ce219c2c8584)Maven home: /Users/justinzhang/Library/Maven/apache-maven-3.9.0Java version: 19.0.2, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk-19.jdk/Contents/HomeDefault locale: zh_CN_#Hans, platform encoding: UTF-8OS name: "mac os x", version: "13.2.1", arch: "aarch64", family: "mac"3、配置maven setting.xml文件先找到maven安装路径，我的路径是~/Library/apache-maven-3.5.0/conf/settings.xml找到之后编辑setting.xml文件<?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"> <mirrors> <mirror> <id>mirror</id> <mirrorOf>central,jcenter,!rdc-releases,!rdc-snapshots</mirrorOf> <name>mirror</name> <url>https://maven.aliyun.com/nexus/content/groups/public</url> </mirror> </mirrors> <servers> <server> <id>rdc-releases</id> <username>xxx</username> <password>xxx(H</password> </server> <server> <id>rdc-snapshots</id> <username>xxx</username> <password>xxx(H</password> </server> </servers> <profiles> <profile> <id>rdc</id> <properties> <altReleaseDeploymentRepository> rdc-releases::default::https://packages.aliyun.com/maven/repository/2113702-release-6l40oS/ </altReleaseDeploymentRepository> <altSnapshotDeploymentRepository> rdc-snapshots::default::https://packages.aliyun.com/maven/repository/2113702-snapshot-zW0Kdb/ </altSnapshotDeploymentRepository> </properties> <repositories> <repository> <id>central</id> <url>https://maven.aliyun.com/nexus/content/groups/public</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>snapshots</id> <url>https://maven.aliyun.com/nexus/content/groups/public</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> <repository> <id>rdc-releases</id> <url>https://packages.aliyun.com/maven/repository/2113702-release-6l40oS/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>rdc-snapshots</id> <url>https://packages.aliyun.com/maven/repository/2113702-snapshot-zW0Kdb/</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>central</id> <url>https://maven.aliyun.com/nexus/content/groups/public</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> <pluginRepository> <id>snapshots</id> <url>https://maven.aliyun.com/nexus/content/groups/public</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> <pluginRepository> <id>rdc-releases</id> <url>https://packages.aliyun.com/maven/repository/2113702-release-6l40oS/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> <pluginRepository> <id>rdc-snapshots</id> <url>https://packages.aliyun.com/maven/repository/2113702-snapshot-zW0Kdb/</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> </pluginRepositories> </profile> </profiles> <activeProfiles> <activeProfile>rdc</activeProfile> </activeProfiles></settings>这样就配置好了Maven。Idea配置现在我们到idea中配置Java和Maven环境总结1、如果你使用的是压缩包安装方式安装Java，只要放到指定目录即可，然后配置Java环境，而使用dmg安装方式安装后的Java目录，必须使用/usr/libexec/java_home -V才能获取取。2、安装好maven之后记得配置setting.xml文件。3、Idea如果报Java相关错，看看是不是没有设置java版本引用lombok与jdk版本对应关系 - 爱码网解决 Maven ‘parent.relativePath‘ of POMMacOS下安装及配置Maven超详细的Java安装教程（Mac 版）
