MacOS搭建JavaWeb环境记录_macbook搭建java web环境

一、jdk

1.1 安装

查看是否安装成功，在终端输入

java -version

成功如下图：

1.2 配置

sudo vi /etc/profile

JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home"
CLASS_PATH="$JAVA_HOME/lib"
PATH=".;$PATH:$JAVA_HOME/bin"

echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

二、maven

2.1  解压到／usr/local

cd /usr/loacl
sudo tar -xvf ~/Downloads/apache-maven-3.3.9-bin.tar 

2.2  配置环境

参考http://maven.apache.org/install.html

 $ vi ~/.bash_profile

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home
MAVEN_HOME=/usr/local/apache-maven-3.3.9
PATH=$PATH:$MAVEN_HOME/bin

export MAVEN_HOME
export PATH

$ source ~/.bash_profile

＊最开始没有加入第一行，查看版本时报错：

$ mvn -version

错误的原因是我的JAVA_HOME配置在/etc/profile中的，这里在.bash_profile中也加上JAVA_HOME的路径即可。如下

$ mvn -v
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /usr/local/apache-maven-3.3.9
Java version: 1.7.0_79, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.11.4", arch: "x86_64", family: "mac"

2.3 配置本地资源路径

打开conf中的setting.xml，添加自定义资源路径，如下

<!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ${user.home}/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->
  <localRepository><span style="font-family: Menlo; font-size: 11px; font-variant-ligatures: no-common-ligatures;">/Users/Bdong/.m2/repository</span><span style="font-family: Arial, Helvetica, sans-serif;"></localRepository></span>

＊之前错误的将路径配置到/usr/local/reposotory里，无法下载，改回本用户路径就好了

2.4 配置eclipse插件

＊eclipse中Help->Eclipse Marketplace搜索关键字maven到插件Maven Integration for Eclipse ,遇到如下错误：

网上查了资料

少了maven依赖的eclipse插件，解决方法如下：

直接在线安装maven2 会出现依赖插件找不到的问题，无法安装。必须先安装gef 插件后才能安装m2eclipse-core 插件，然而安装m2eclipse-extras 插件又依赖subclipse 插件。所以，三个插件的正确的安装顺序是：gef插件 》subclipse插件 》m2eclipse插件。 
m2eclipse-core插件 ——依赖——＞gef插件 
m2eclipse-extras插件 ——依赖——＞subclipse插件

启动eclipse，点击window——>preferences——>install/update——>available software sites，点击Add
添加如下信息：

GEF             http://download.eclipse.org/tools/gef/updates/interim/
Subclipse      http://subclipse.tigris.org/update_1.6.x

下载这几个插件
然后再重新安装maven插件 

m2e http://download.eclipse.org/technology/m2e/milestones/1.4 （以低版本替代）

其它省略的软件基本属于直接安装的，无需记录
