Java JAX-RS Server API generator for OpenAPI Generator Plus

An OpenAPI Generator Plus template for a Java API server using JAX-RS.

Overview

The generated code has useful features:

Exceptions are used for non-default responses, such as 400 responses, so you can only return the specified status codes.
Response Exceptions can have an entity type to return with the error response.
Model objects and enums will be nested in the API service if they are inlined in the specification.

Using

See the OpenAPI Generator Plus documentation for how to use generator templates.

`authenticationRequiredAnnotation`	`string`	Annotation to add to API methods that require authentication.	`undefined`
`useJakarta`	`boolean`	Whether to use `jakarta` packages instead of `javax` packages.	`false`

Packaging

Property	Type	Description	Default
`maven`	`MavenConfig`	Configuration for generating a Maven `pom.xml`	`undefined`

`MavenConfig`

Property	Type	Description	Default
`groupId`	`string`	The Maven template groupId	`com.example`
`artifactId`	`string`	The Maven template artifactId	`api-server`
`version`	`string`	The Maven template version	`0.0.1`

General

Property	Type	Description	Default
`hideGenerationTimestamp`	`boolean`	Whether to hide the timestamp in the `@Generated` annotation.	`false`

Testing

Property	Type	Description	Default
`includeTests`	`boolean`	Whether to generate test classes.	`false`
`junitVersion`	`4` \| `5`	The JUnit version to use.	`5`

Overrides

Property	Type	Description	Default
`imports`	`string[]`	Additional imports to add to all generated classes.	`undefined`
`customTemplates`	`string`	The path to a directory containing custom Handlebars templates, relative to the config file. See Customising below.	`undefined`

Customising

This generator supports a customTemplates config file property to specify a directory containing Handlebars templates that will be used to override built-in templates.

Any custom template will have the original template available as a partial named by prefixing the template name with original, and then upper-casing the first letter, e.g. originalBodyParams.

Some of the templates in the generator are designed to support overriding for custom requirements. Please inspect the templates in the templates directory.
