# [Mac-java环境安装包：JDK11.0.2版本，和Tomcat7.0.92][Mac-java_JDK11.0.2_Tomcat7.0.92] #

# 1、配置JDK #

## 首先安装JDK： ##

### [Mac安装JDK方法][Mac_JDK] ###

a>安装好之后，打开idea软件。

b>编写一个简单的helloworld文件

c>点击上边锤子旁边的东西

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDM1NDY4Mw_size_16_color_FFFFFF_t_70 1][]

d>配置如下：1添加一个application，2class名字，3项目路径，4、jdk路径一般idea都会自动显示，如果更换重新选择路径即可（注：Mac的jdk选择到home文件即可：例如：/Library/Java/JavaVirtualMachines/jdk1.8.0\_201.jdk/Contents/Home）

e>点击保存，点击ok，然后右击点击run在控制台上出现helloworld即可成功。

c>点击Local之后会出现下图，开始配置：1、Tomcat名字随便起；2、Tomcat路径到根路径（我的问：/Library/tomcat）；3、选择浏览器；4、选择jdk一般会自动加上；5、端口号，不用使用重复的端口号

f>浏览器页面，由于我没有写jsp文件所以不会显示helloworld，但是弹出浏览器标识配置Tomcat已经完成。![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDM1NDY4Mw_size_16_color_FFFFFF_t_70 11][]
