IDEA method to deploy JavaWeb project to Tomcat server

IDEA creates a traditional JAVA WEB project (built with maven)

Method 1

 File --> NEW --> Project --> Java (check Web Application)

Method 2

 File --> NEW --> Project --> Java Enterprise (check Web Application)

IDEA deploys JAVA WEB project

IDEA does not place the project in tomcat's webapp directory, but the project is still in the source project directory. IDEA adopts a non-invasive Tomcat project deployment method (no modification of any tomcat files) <virtual directory method>

 After IDEA starts Tomcat, the corresponding projectName directory will be created in the ${user.home}/.IntelliJIdea/system/tomcat directory, and copy 3 directories to the ${user.home}/.IntelliJIdea/system/tomcat/projectName directory. This will cause each project to correspond to three directories: conf, logs, and work: conf, logs, and

In the conf/Catalina/localhost/ROOT.xml configuration file, the configuration associated with the JAVAWEB project is as follows:

 <?xml version="1.0" encoding="UTF-8"?><Context path="" docBase="G:/work/java/je/out/artifacts/je_war_exploded" />

conf/Catalina/localhost/ROOT.xml configuration file properties

 <?xml version="1.0" encoding="UTF-8"?><Context path="" docBase="G:/work/java/je/out/artifacts/je_war_exploded" />

path

Set the URL to access the web application portal (set URL entry routing)

docBase

Set the project path of the web application

className

Specify the Java class name that implements the Context interface

reloadable

If set to true, tomcat will automatically reload according to WEB-INF directory changes. It will be set to true during general development/debugging, and the official production environment will be set to false.

Virtual Directory

effect:

1. When the host:port in the URL is the same, multiple projects can be deployed (usually this is rarely used)

For example:

http://localhost:8080/
http://localhost:8080/manager
http://localhost:8080/admin

2. Separate the project storage location from webapps in the root directory of tomcat, which is safer

Configuration method one

Create: tomcat root directory /conf/Catalina/domain name/test.xml file

content:

 <?xml version="1.0" encoding="UTF-8"?> <Context docBase="G:/work/java/je/out/artifacts/je_war_exploded" />

Visit url: http://localhost:8080/test

Virtual Host

Function: A server binds multiple domain names, one domain name corresponds to one project (mostly) or one domain name corresponds to multiple projects (very rare)

Configuration method

Add the following code to the tomcat root directory /conf/server.xml file:

 <Host name="www.jalja2.org" appBase="E:/Learning/activeMq/app2" unpackWARs="true" autoDeploy="true"></Host>
