Maven can manage the jar packages that the project relies on, with GroupID, Artifactid, and version numbers to uniquely identify a jar package. This prevents the web-inf/lib of the jar package from being inconsistent under the old Web project. Maven also automatically downloads the jar packages that are added to the jar package.

Src/main/java
This folder is stored in Java source code, publish the project will be under the folder of the class file copied to the Web-inf/classes directory

Src/main/resources
This folder generally placed configuration files, such as xml,properties files, etc., can also be placed in Java files, just a convention, when the project was published
Files for this folder are also copied to Web-inf/class
As for test, there are some similarities, but these are testing code, and using Maven should know that.

Src/main/webapp
The contract in Maven is to think of the folder as a Webroot directory in a normal Web project, see the Deploy path on the right, and publish the project
is published to the root directory/. The folder is in the built Maven WEB project, and there are no Web-inf/classes,web-inf/lib folders in it
Need to be built manually

In fact, this is also possible to run the project, debugging the project, however, if you run the project's Pom.xml file will be an error, why,
Because Maven treats the Src/main/webapp file as a webroot in a normal Web project, the inside of your configuration ()
Without configuration, it will be an error.
What to do, 2 steps.
1. Select Webcontent,remove to drop it
2, create a new, the source folder for Src/main/webapp,deploy path is/
Click Apply,ok.

Finally, the MAVEN library must be mapped to Web-inf/lib, as follows, click the Add button to enter
