This project provides integration between Swagger and Spring MVC.
Spring beans annotated with @Controller
are detected and parsed for documentation.
The project is available from maven:
<dependency>
<groupId>com.mangofactory</groupId>
<artifactId>swagger-springmvc</artifactId>
<version>0.6.0</version>
</dependency>
Currently, a subset of Swagger annotations are supported. Support will improve over the coming releases.
All @Controller
classes are parsed, and methods annotated with @RequestMapping
are generated.
Additionally, @Api
at the class level, and @ApiOperation
at the method level are both supported.
To wire up support, add the following into your spring context file (Configuration based on the example project):
<!-- to specify swagger properties
documentation.services.basePath=http://localhost:8080/swagger-springmvc-test
documentation.services.version=1.0
-->
<context:property-placeholder location="classpath:swagger.properties" />
<!-- pulls in the Controllers to document -->
<context:component-scan base-package="com.mangofactory.swagger.springmvc.example" />
<!-- Configuration Bean -->
<bean id="documentationConfig" class="com.mangofactory.swagger.configuration.DocumentationConfig"/>
<!-- Custom extensibility module (bean) Has override methods to customize the document generation-->
<bean id="extensibilityModule" class="com.mangofactory.swagger.springmvc.example.config.ExampleExtensibilityModule" />
The basePath
property is external-facing url the maps to your SpringMVC dispatcher servlet.
This creates a controller at /api-docs
from this uri, which serves swagger's raw documentation in JSON format. (eg
., In the above example, http://www.mydomain.com/swagger-springmvc-example/api-docs
)
Some deviations from the default Swagger API exist. Wherever possible, these are inteded to be implemented as-well-as the default Swagger implementation, rather than as a replacement.
The overarching goal is to support generation of the Swagger JSON, with minimal intrusion to the code itself.
Declaration of errors supports the standard Swagger @ApiErrors
and @ApiError
annotations.
In addition, there are com.mangofactory.swagger
implementations of these that reduce the amount of per-method code (notably, at the cost of some flexibility)
@ApiError
is now supported at the exception class level, as shown here:
@ApiError(code=302,reason="Malformed request")
public class BadRequestException {}
This allows errors to be declared as follows:
@ApiErrors({NotFoundException.class,BadRequestException.class})
public void someApiMethod() {};
or, simply using a throws
declaration:
public void someApiMethod() throws NotFoundException, BadRequestException {};
An example of Swaggers PetStore in Spring MVC is available here
