Tooling around Maven and Gradle to generate code from OpenAPI/Swagger specs

Swagger-Codegen-Tooling

The project provides some tooling around Maven and Gradle* to generate code from OpenAPI-Specs. It comes with custom-templates to support Spring-MVC/Spring-Boot projects. Instead of generating code only once when a project starts (design phase), code will be generated at every build to make sure your code is in sync with your spec. So controllers/resources are generated as interfaces developers have to implement then. So changes in the spec should be reflected immediately on build/compile-step.

• The Gradle plugin moved to its own repository at zalando-incubator

Getting started with Maven

To get started in a Maven project just add the following plugin-definition to you pom.xml.

    <plugin>
        <groupId>org.zalando.maven.plugins</groupId>
        <artifactId>swagger-codegen-maven-plugin</artifactId>
        <version>${version}</version>
        <configuration>
            <apiFile>${project.basedir}/src/main/resources/api.yaml</apiFile>
            <language>springinterfaces</language>
            <apiPackage>com.example.project.api</apiPackage>
            <modelPackage>com.example.project.model</modelPackage>
        </configuration>
        <executions>
            <execution>
                <id>swagger-codegen</id>
                <goals>
                    <goal>codegen</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

According to your OpenAPI-spec (api.yaml) code will be generated in ${basedir}/target/generated-sources/swagger-codegen

More examples how to use the Maven-Plugin can be found in the integration-test section.

Development/Contribution

Build

The project itself uses Maven:

mvn clean install

Run with integration-tests enabled

mvn clean install -Pintegration

TODO's

• improve Templates (what about Controllers that delegate to an interface)
• improve documentation
• prepare an example that uses spring-restdocs
