(Assuming that the first 4 have been installed)

One, eclipse creates MAVEN project

After creation, the project structure is as follows

TOMCAT modification

<role rolename="manager-gui"/>  
<role rolename="admin"/>  
<role rolename="admin-gui"/>  
<user username="tomcat" password="tomcat" roles="admin-gui,admin,manager-gui,manager-script,manager"/>

  <server>
      <username>tomcat</username>
      <password>tomcat</password>
    </server>

Preparation is complete

Start deployment

1. Start the TOMCAT service first

2. CMD enters the WEB project folder directory

3. Input (mvn tomcat7: deploy)

3. The display is successful, and the webApp in the TOMCAT directory will automatically add the WAR package

Visit address: http://localhost:8080/myapp/index.jsp

4. To cancel the deployment, you need to enter the instructions first

mvn tomcat7:undeploy

Then stop the TOMCAT service, the corresponding WAR package will also be deleted
