To start building springCloud’s client service.
First, the SpringBoot project is also generated online.
IO/start.spring. IO /
Because, I built spingCloud+ Eureka + Swagger +mybatisPlus at one time, so this time, I will show you at one time.
Because this time, I need to add some new configuration files instead of just these three, I will first show you the directory of the services that have been set up successfully:
The first is the pom.xml file:

Ok, the configuration file is almost complete, but if you start the service at this time, you will still get an error because you don’t have the corresponding controller, Serivice, Mapper, etc.
Therefore, I created an entity class that specifically generated the code.

With this annotation, when you call the delete method of mybatisPlus, it will logically delete your data.
Ok, I configured the generated Java files in the BLOG folder of disk D, took them out and put them into the project.
As shown in the figure:
Open the web page and type in the url: localhost:1111.
Click: http://192.168.1.5:2222/permission, you can into the swagger page, as shown in the figure below
conclusion
The Eureka client I built is actually satisfying the development needs of just playing by yourself.
The important thing to note is that you can create files to your liking, but make sure to pay attention to configuration files. For example, in the application.properties file there is a configuration like this:
