intellij idea 工具配置完成
二：下载tomcat ，下载地址：http://tomcat.apache.org/
我选择下载的是8.5.28，下载后解压就可以。
三：创建java web项目
1、在自己希望的目录下创建一个java web 的工作空间，如：D:\webworkspace
2、
选择
next
输入项目名称后点击finish。
配置项目：
选择file
选择Facets,如图，点击左边Web，然后点击右边加好，弹出对话框，点击ok
在项目目录WEB-INF下创建两个文件夹：classes和lib
其中classes用来存放输出文件，lib用来存放需要的jar包
配置classes和lib方法如下：
配置classes文件输出路径
配置lib目录
添加tomcat
配置tomcat
选择项目依赖包
然后添加jar存放路径即可
上述全部部署完成后即可编写简单的编写servlet源文件
然后编写一点自己的demo代码进行测试：
启动tomcat
打开postman,请求服务器,测试数据:
数据请求成功:
