Swagger Codegen - Play Scala

A code generator for Swagger which generates API clients with the help of the PlayWS library. This code generator is based on the akka-scala generator included in the Swagger Codegen distribution.

Versions

Project	Play
0.1.x	2.4
0.2.x	2.5
master	2.6

Create client

Download swagger codegen executable into the root directory of this project:

wget http://repo1.maven.org/maven2/io/swagger/swagger-codegen-cli/2.3.0/swagger-codegen-cli-2.3.0.jar -O swagger-codegen-cli.jar

Execute the script

scripts/codegen.sh -i ${SWAGGER_SPEC_FILE} -o ${SWAGGER_CLIENT_DIR} -c ${SWAGGER_CONF_FILE}

To run the bundled petstore example:

scripts/codegen.sh -i conf/petstore.yaml -o build -c conf/config.json

Compile the client:

cd build
sbt compile

Config options:

The code generator supports the following config options:

Name	Description
modelPackage	The package for generated model classes
apiPackage	The package for generated api classes
invokerPackage	The package for generated root classes
configKeyPath	Path under which the config must be defined
projectOrganization	Project organization in generated build.sbt
projectName	Project name in generated build.sbt
projectVersion	Project version in generated build.sbt
scalaVersion	The Scala version to use in generated build.sbt

How to use

To use the client you must inject a corresponding API handler into your controller or service. Every API handler itself has a dependency to the ApiInvoker which must be instantiated with the global configuration and an instance of the WSClient. It's the best to wire this dependencies with your preferred DI method.

Every method created for you API handler accepts, additional to the parameters created from the Swagger spec, an optional request config which can be used to override the global config.

Global config

Property	Description
url	The optional API URL. If this URL is defined then it has precedence over the URL defined in the Swagger spec.
requestTimeout	The request timeout. Defaults to 20 seconds.

Request config

Property	Description
url	The optional API URL. If this URL is defined then it has precedence over the URL defined in the Swagger spec and the global config.
timeout	The request timeout. Defaults to None, which means the global config has precedence.

WS Client config

The underlying WSClient can also be configured in your Play configuration.
