Foreword: Another year of summer is approaching, looking for an internship? I'm afraid it won't work if I don't have many projects in hand. Today I will bring you a relatively simple Web project. Come and learn!
1. Project introduction
1. Cloud lending library management system
Technology stack: (Spring+SpringMVC+Mybatis+MySql+BootStrap+Jquery)

1. Login confirmation
2. New book recommendation
3. Book borrowing or editing
4. Add new books
5. Borrow and view
6. Inquiry about borrowing records
2. Project Construction
1. Build a database
1. Create a database named cloudlibrary, you can use Navicat to import SQL files, and it will be given in the project!
2. Find the corresponding file and import it to create successfully!
2. Create a JavaEE project
1. Select Tomacat8, and the project name is self-made
2. The basic structure of the project is shown in the figure
3. Configure the Pom file

</project>3. Understand Maven
Maven repository
In Maven terminology, a repository is a place.
The Maven warehouse is a third-party library that the project depends on. The location of this library is called a warehouse.
In Maven, any dependency, plug-in or project build output can be called a component.
The Maven repository helps us manage components (mainly JARs), it is where all JAR files (WAR, ZIP, POM, etc.) are placed.
There are three types of Maven repositories:
- local
- central
- remote
local warehouse
Maven's local warehouse is not created after Maven is installed, it is created when the maven command is executed for the first time.
When running Maven, any artifacts required by Maven are obtained directly from the local repository. If the local warehouse does not have it, it will first try to download the components from the remote warehouse to the local warehouse, and then use the components of the local warehouse.
By default, regardless of Linux or Windows, each user has a warehouse directory named .m2/repository/ under their own user directory.
The Maven local repository is created by default in the %USER_HOME% directory. To modify the default location, define another path in Maven's settings.xml file in the %M2_HOME%\conf directory.
4. Project link
Self-learning:
Remember to like it! !
It's not easy to post, I implore the big guys to raise your hands!
Likes: Likes are a kind of virtue, and they are the recognition of my creation by the bosses!
Comments: There is no white contact, it is the beginning of communication between you and me!
Collection: May you pick more, it is the appreciation of the bosses to me!
