1, Create parent project Maven Project to manage dependencies

 

  GroupId: the unique identifier in the project, which corresponds to the package structure in java. Here, it represents the structure in the project

  ArtifactId: unique identifier in the project, corresponding to the project name

 

  introduce relevant dependency, and we will talk about the specific dependency later.

2, Create EurekaServer registry

  Eureka: service discovery is one of the five cores of SprigCould. Note that we create a child project by right clicking the parent project, and we put GroupId in general.

 

  we write the eureka coordinates

 

  we write the startup class of the service

 

  we write the configuration file application.yml under resources

 

3, Create Zuul gateway

  Zuul: service discovery is one of the five cores of SprigCould. Note that we create a child project by right clicking the parent project, and we put GroupId in general.

 

  we write the eureka coordinates

 

  we write the startup class of the service

 

  we write the configuration file application.yml under resources

 

4, Create product micro service

  item: the product micro service will include the management of a series of content related to the product. We use the aggregation project to create it.

  start the parent project of commodity micro service first

 
 

  we modify item coordinates

 

  we no longer write logic in you item to delete src folder, and create a sub project, you item interface, to save interface and entity class.

 

  create a subproject, you item service, for commodity service logic implementation.

 

  we modify the service coordinates.

  we write the startup class of service

 

  we write the service configuration file

 

  we modify the configuration file of gateway and add routes

 

5, Create a general tool module

  general tools: save something commonly known by convention for sharing among modules.

 

  we start the service in turn
