环境准备只需四步：
第一步：jdk 1.8
第二步：idea 15
第三步：maven 3.2
第四步：检查环境是否配置正确

  1. JDK 1.8
    下载路径：JDK 1.8
    安装完成后，配置环境变量
    打开系统环境变量，添加几个变量
    JAVA_HOME=C:\Program Files\Java\jdk1.8
    CLASSPATH=.;%JAVA_HOME%\lib
    修改PATH变量的值
    PATH=%JAVA_HOME%\bin
    检查：cmd启动控制台后，运行java -version
    java version "1.8.."
    有上述字样，说明java安装和配置成功
    动画说明：
    -jdk
  2. IDEA 15
    下载好idea 15之后，注册key
    注册步骤
    登录http://15.idea.lanyus.com/
    随意写入一个用户名，点击获得注册码
    全选拷贝画圈的内容
    动画说明：
    -idea
  3. Maven 3.2
    解压即可
  4. 在idea 15中配置java和maven
    配置maven
    settings-Build,Execution,Deployment-Build Tools-Maven，Maven home directory设置解压的maven路径
    -idea-maven

通过以上配置，java开发环境就准备的差不多了。

下面可以建一个maven项目
正常新建maven工程
File-New-Project，对话框左侧选择MAVEN。在Project SDK栏，点击"New..."，找到安装过的JDK，应该能够检测到1.8版本
