To create a maven project on Eclipse, it is recommended to use the latest version of Eclipse or above 4.5, why? Because you do not need to manually install the m2eclipse plugin to manage Maven projects
Therefore, it is recommended that you use the latest version of the eclipse mars2 4.5.2 development tool. Download address: http://www.eclipse.org/downloads/
Not much to say about the environment, it will.

5> After the skeleton is built, you will find an error, it doesn't matter, ignore it first, and solve it later:
6> Next, you need to configure the related maven: you need to add the following Source Folder,
They are: src/main/resources, src/main/java, src/test/resources, src/test/java. But this step will go wrong:
1) Right-click on the project -->new-->Source Folder
2) Obviously it already exists, so you need to delete the original project --> right click on the project and select "Build Path" --> "Configuration Build Path..."
3) Just face the "1)" step before proceeding. As shown in the figure: After repeating the construction of src/main/java, src/test/resources, and src/test/java, it is ok

Right-click on the project and select properties, then click Project Facets on the left, check Dynamic Web Module, and click Apply-->OK. Ideally it should be possible to appear under the project
WebContent directory. If not, first go back to the Project Facets interface, uncheck Dynamic Web Module, and click Apply. Then re-tick, the following will appear
Now the link of "further configuration available", click to enter, and check to generate the web.xml file.

Click Next. Find the webapp directory under src/main and click Finish. Continue to click Add and select Java Build Path Entries. Point the current build path to Maven Dependency. Click Apply and OK. )

Then apply. At this time, select 2.5 again, then check it again, and then click further configuration available as shown in the figure to change the content directory to src/main/webapp to confirm.
After completion, the directory looks like this
