Intellij Idea 2017 to create web projects and tomcat deployment combat

Related software: Intellij Idea2017, jdk16, tomcat7

Intellij Idea can be installed directly (you can choose the installation directory you set according to your needs), jdk can use 1.6/1.7/1.8, the main thing is to configure the system environment variables, download the compressed package from the official website of tomcat7 on tomcat7 and extract it.

1. Create a simple web project

1. Create a web project

File -> new Project -> select project sdk as 1.6 (if you don't have sdk, please configure it first) -> Next

create project from template page, uncheck any options -> Next

Enter the project name: webDemo -> Next -> Finish

2. Create a Module

Click on the project name webDemo -> right click and select New, select Module -> Module SDK, select 1.6 -> check Web Application (3.1) under JavaEE, note that the version under the window corresponds to 3.1, and Create web.xml is checked -> Next

Enter Module name as firstweb -> Finish

3. Create a good web project

4. Create two folders in the web/WEB_INF directory: classes and lib

classes are used to store the compiled class files, lib is used to store third-party jar packages

5. Configure the folder path

File -> Project Structure (ctrl + shift + Alt + s) or use the toolbar shortcut -> select Modules

-> Select Paths -> Select "Use module compile out path" -> Set both Outputpath and Test output path to the classes folder you just created

选择当前窗口的Dependencies -> 将Module SDK选择为1.6 ->点击右边的 + 号 -> 选择 “1 JARS or directories ...”

-> 选择刚刚创建的lib文件夹 -> OK

-> 选择Jar Directory -> OK

-> Apply -> OK

三、配置Tomcat容器

打开菜单Run -> Edit Configurations...

点击 “+” ，选择 “Tomcat Server” -> 选择“Local”

在Name出输入新的服务器名，点击 "Application Server" 后面的 "Configure..."，弹出Application Servers窗口，在Tomcat Home 选择本地安装的tomcat目录 -> OK

在"Run/Debug Configurations"窗口中Name一栏输入服务器的名字tomcat7，在“Server”面板中，勾选取消“After Launch”，设置“HTTP port”和“JMX port”（默认值即可），点击Apply -> OK，至此tomcat配置完毕（左边列表中tomcat图标上小红叉是未部署项目的提示，部署项目后就会消失）。
