We learned from the online Xi, simulating that if we were in actual work, we would first get a project that was not complicated but the technology was relatively old, because it was difficult for us to directly participate in the development of large and new projects as newcomers.
Let's search for a copy from the Internet, first**down**, **as follows:
*Address: (Access code: 7567).
Import the database to our local computer.
Import the project into your local environment.
First, we copy the project into our working development environment.
Import in the IDE (Eclipse, MyEclipse, Idea are OK).
And then. 
Go on. 
The item appears in the navigation bar.
Change the address of the database connection.
Because all projects must have a database address configuration, regardless of the framework used. So we need to find the corresponding file to make changes. Change the database password and account below to your own database address.
Generally at this time, we only need the ** project is okay, you can run, we use tomcat as the application server, but the ** project needs to do a conversion, the project will be converted, the conversion location is as follows:
Convert the project. 
Check the box after the conversion is complete.
Next, change a directory.
The directory changes are as follows.
Add to the Tomcat application server.
Then we can run ** without any errors.
We can access the corresponding project in the browser.
If you can't connect after clicking Login, you can change the MySQL connection package in the system.
