maven project import

I have built a new maven project before, this time I used another project to directly use the

software version
eclipse-jee-luna-SR2-win32-x86_64
JDK1.8
apache-tomcat-8.0.26
apache-maven-3.3.3

process
due to download The eclipse version has the maven plug-in directly, so the plug-in does not need to be installed

Install jdk maven, set the environment variable After

importing the project, the maven project is automatically recognized, no need to convert it. This should be different for each machine. Publish it directly to tomcat, and you can run it. No further configuration is required
