关于java:Mac安装开发环境应用端篇

前言

跟前端篇一样，当初记录一下后盾利用端开发环境的搭建，针对的是 java 环境，当初分享给大家。

操作

1、下载和装置 Java
下载地址在这

下载 dmg 装置即可，接着查问装置 java 的地位

/usr/libexec/java_home -V

找到 java 装置地位 之后，当初咱们来编辑.bash_profile 文件, 增加 java 环境

#java home
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.

保留完之后，别忘了source ~/.bash_profile

2、下载和装置 Maven
点击官网下载地址下载

下载之后解压到你想要保留的中央即可。

保留完之后，配置一下环境变量，再次编辑~/.bash_profile

#java home
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.

# maven home
M3_HOME=/Users/zhangwei/Library/apache-maven-3.5.0

export PATH=$JAVA_HOME/bin:$M3_HOME/bin:$PATH:

这样就实现了 Java 和 Maven 的装置，查看 Java 和 Maven 的版本

java --version
mvn -v

3、配置 maven setting.xml 文件
先找到 maven 装置门路，我的门路是

~/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">

                    </releases>
                    <snapshots>
                        <enabled>false</enabled>

            </pluginRepositories>
        </profile>
    </profiles>
    <activeProfiles>
        <activeProfile>rdc</activeProfile>
    </activeProfiles>
</settings>

这样就配置好了 Maven。

Idea 配置

当初咱们到 idea 中配置 Java 和 Maven 环境
