MyEclipse Database Reverse Hibernate tutorial

. First of all, our preparation

1. Project

　　　　

2. Database

Database execution commands. sql

We're ready now. With the above items and tables, we started the reverse engineering first step

1. Text does not matter, look at the picture

2. Next, we'll configure our Hibernate core Jar Package

Right click our project select myeclipse--"Project Facets-->install hibernate facet

3. Now we're back to starting with our own db.

4. Then that's it, let's take a look at our inverse entity class

5. This is good, thank you for watching, we learn together

Attach a copy of the configuration
