Step 2: Generate Spring Boot code

[tfesenko]

1. Add a new GenTarget for "Java Spring (Boot + MVC + CloudFeign) Server".

The result should be similar to what you can find on branch step_1b.

2. Update pom.xml to use latest OpenAPI Generator

Add this to the root pom.xml file of the RepreZen project root folder(not the pom.xml file in the newly created GenTemplate folder):

        <dependency>
        	<groupId>org.openapitools</groupId>
        	<artifactId>openapi-generator</artifactId>
        	<version>3.2.3</version>
        </dependency>

3. Update parameters in Java Spring (Boot + MVC + CloudFeign) Server.gen file

Change the following parameters
For output location and packages:

• relativeOutputDir: ../../../implementation/springboot-petstore-demo
• modelPackage: com.reprezen.demo.springboot.model
• apiPackage: com.reprezen.demo.springboot.api
• invokerPackage: com.reprezen.demo.springboot
• configPackage: com.reprezen.demo.springboot.swaggerui
• basePackage: com.reprezen.demo.springboot

For maven artifacts:

• groupId: com.reprezen.demo
• artifactId: petstore-demo
• artifactDescription: "Demontration of the Contract-as-Code approach with Spring Boot artifacts generated from an OpenAPI3 doc"

For generated Java classes:

  openApiCodegenConfig: 
    hideGenerationTimestamp: true
    delegatePattern: true
    # the java8 option generates default methods in interfaces which. Because of it, unimplemented methods in interface implementations will NOT be detected by the compiler.  
    java8: false

Git branch: step_1c

4. Generate Spring Boot code running the "Generate Java Spring (Boot + MVC + CloudFeign) Server" action from the toolbar.

5. Create a new Eclipse project for generated artifacts

Open the generated artifacts as a project by right-clicking on the implementation folder and selecing "Import > Maven / Existing Maven Project". This will create a new "petstore-demo" Maven project in API Studio.

Notice that we have PetsApiDelegate among other generated artifacts. We will provide implementation of this interface in the next step.
