Environment

You will need the following dependencies before starting this tutorial:

  • Java JDK 11 (I prefer OpenJDK but Oracle JDK will do)
  • Maven
  • Git
  • Docker

The use of docker-compose is optional but can sometimes be problematic for Windows users.

Assuming the above software packages are installed, we need to create a workspace and clone the projects needed for this tutorial. The following will assume your workspace is in a directory named networknt under your home directory.

cd ~
mkdir networknt
cd networknt
git clone https://github.com/networknt/light-codegen.git
git clone https://github.com/networknt/light-example-4j.git
git clone https://github.com/networknt/light-oauth2.git
git clone https://github.com/networknt/light-docker.git
git clone https://github.com/networknt/model-config.git
git clone https://github.com/networknt/light-config-test.git

We are going to re-generate the petstore project in light-example-4j. Rename the existing directory in light-example-4j to petstore.bak

If you feel like you may have made an error while following this tutorial, you can compare your working code with the petstore.bak directory to find any differences.

cd ~/networknt/light-example-4j/rest/openapi
mv petstore petstore.bak
cd ~/networknt

Build the light-codegen project so we can use it to generate our petstore project. There are many ways to use light-codegen but for the purposes of this tutorial, we will just build and use the codgen-cli.

cd ~/networknt/light-codegen
mvn install -DskipTests

Our environment and light-codegen are now ready. In the next step, we will generate the project using the OpenAPI 3.0 specification.
