An upgrade to the swagger-springmvc project to the latest Swagger specification (1.2).
The swagger specification upgrade to 1.2 has several feature additions and has also refactored it's core model structure.
See swagger-core
The demo/sample application is built off of swagger-ui tag v2.0.4
There are currently some features not fully supported:
- Model generation - work in progress to modularize the model generation from prior versions of swagger-springmvc. This version uses the model generation that ships with swagger-core which is not as powerful when it comes to polymorphic models.

- Authorization types: (OAuth, ApiKey, BasicAuth).
- ApiInfo: info, title, licencing, etc.
- Http media types (produces/consumes).
- Model annotation changes.
- resource & base path changes.
- Swagger core library has upgraded to scala 2.10.0. For more detail see: https://github.com/wordnik/swagger-core/wiki/1.2-transition.
- Spring 3.2.x or above
- scala lib 2.10.0
- jackson 2.1.5 (older/newer versions may work)
By no means is the documentation great but the project has plenty of tests and we're slowly chipping away at the documentation. The latest javadocs are available here. Contributions that add to test coverage and documentation is always welcome! :)
Change Log is available for the changes since 0.8.3
- Remove the following autowired fields in your spring configuration
@Autowired
private SpringSwaggerModelConfig springSwaggerModelConfig;
- Add the following autowired fields in your spring configuration
@Autowired
private ModelProvider modelProvider;
- Make sure any customizations to the object mapper are appropriately added in an ObjectMapper bean definition
/**
* Object mapper.
*
* @return the configured object mapper
*/
@Bean
public ObjectMapper objectMapper() {
//This is the opportunity to override object mapper behavior
return new ObjectMapper();
}
- Configure the swaggerApiResourceListing bean with the model provider that is autowired or provide your own implementation
// Set the model provider, uses the default autowired model provider.
swaggerApiResourceListing.setModelProvider(modelProvider);
- Configure the blah bean with an implementation of the resource grouping strategy
//How to group request mappings to ApiResource's typically by spring controller classes. This is a hook to provide
// a custom implementation of the grouping strategy. By default we use SpringGroupingStrategy. An alternative is
// to use ClassOrApiAnnotationResourceGrouping to group using Api annotation.
apiListingReferenceScanner.setResourceGroupingStrategy(springSwaggerConfig.defaultResourceGroupingStrategy());
- Allows configuration of default response messages based on HTTP methods which are displayed on all api operations on swagger-ui
E.g. Default response messages for HTTP GET methods
responses.put(GET, asList(
new ResponseMessage(OK.value(), OK.getReasonPhrase(), toOption(null)),
new ResponseMessage(NOT_FOUND.value(), NOT_FOUND.getReasonPhrase(), toOption(null)),
new ResponseMessage(FORBIDDEN.value(), FORBIDDEN.getReasonPhrase(), toOption(null)),
new ResponseMessage(UNAUTHORIZED.value(), UNAUTHORIZED.getReasonPhrase(), toOption(null))
));
Configurable global ignored spring mvc controller method parameters/HandlerMethodArgumentResolver
's
Annotation classes can also be added here to ignore method parameters with a specific annotation.
E.g.
HashSet<Class> ignored = newHashSet();
ignored.add(ServletRequest.class);
ignored.add(ServletResponse.class);
ignored.add(HttpServletRequest.class);
ignored.add(HttpServletResponse.class);
ignored.add(BindingResult.class);
ignored.add(ServletContext.class);
- Configurable swagger type substitutions
E.g.
AlternateTypeProvider alternateTypeProvider = new AlternateTypeProvider();
TypeResolver typeResolver = new TypeResolver(); //dependency on com.fasterxml.classmate
// Add a rule that substitutes ResponseEntity<AnyClass> to AnyClass
// NOTE: WildcardType is an in-built type used for type substitutions of generic
// types
alternateTypeProvider.addRule(
newRule(typeResolver.resolve(ResponseEntity.class, WildcardType.class),
typeResolver.resolve(WildcardType.class)));
// Add a rule that substitutes LocalDate to Date
alternateTypeProvider.addRule(
newRule(typeResolver.resolve(LocalDate.class),
typeResolver.resolve(Date.class)));
//After setting up the custom provider wire it up by calling swaggerGlobalSettings.setAlternateTypeProvider
-
Configurable uri path providers by implementing
SwaggerPathProvider
-
Exclude controller methods based on annotations
E.g.
List<Class<? extends Annotation>> annotations = new ArrayList<Class<? extends Annotation>>();
annotations.add(ApiIgnore.class);
- Flexible Inclusion or exclusion of paths using regex expressions. Make sure the include patterns apply
List<String> DEFAULT_INCLUDE_PATTERNS = Arrays.asList(new String[]{
"/business.*",
"/some.*",
"/contacts.*"
});
web application context xml config
<!-- Enable scanning of spring @Configuration classes -->
<context:annotation-config/>
<!-- Enable the default documentation controller-->
<context:component-scan base-package="com.mangofactory.swagger.controllers"/>
<!-- Pick up the bundled spring config. Not really required if you're already importing the configuration bean
as part of an application specific configuration bean via the previous component scan-->
<context:component-scan base-package="com.mangofactory.swagger.configuration"/>
Configuration is slightly verbose but on the upside it provides several hooks into the library.
