Swagger Doclet Build Status

A JavaDoc Doclet that can be used to generate a Swagger resource listing suitable for feeding to swagger-ui.

Usage

To use the Swagger Doclet in your Maven project, add the following to your POM file.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>…</groupId>
    <artifactId>…</artifactId>
    <version>…</version>
    
    <dependencies>
        …

                            <additionalparam>-apiVersion 1 -docBasePath /apidocs -apiBasePath /</additionalparam>
                        </configuration>
                        <goals>
                            <goal>javadoc</goal>
                        </goals>

Example

An example project using Dropwizard is included in jaxrs-doclet-sample-dropwizard. To get it running, run the following commands.

$ cd jaxrs-doclet-sample-dropwizard
$ mvn package
$ java -jar target/jaxrs-doclet-sample-dropwizard-0.0.4-SNAPSHOT.jar server sample.yml

The example server should be running on port 8080:

$ curl localhost:8080/apidocs/service.json
{
  "apiVersion" : "1",
  "basePath" : "/apidocs/",
  "apis" : [ {
    "path" : "/Auth.{format}",
    "description" : ""
  }, {
    "path" : "/HttpServletRequest.{format}",
    "description" : ""
  }, {
    "path" : "/ModelResource_modelid.{format}",
    "description" : ""
  }, {
    "path" : "/Recursive.{format}",
    "description" : ""
  }, {
    "path" : "/Response.{format}",
    "description" : ""
  }, {
    "path" : "/greetings_name.{format}",
    "description" : ""
  } ],
  "swaggerVersion" : "1.1"
}
$

Override Swagger UI

To override the swagger ui included with the doclet, create your own swagger-ui.zip file and add a swaggerUiZipPath to the additionalparam attribute in the pom file.

<additionalparam>-apiVersion 1 -docBasePath /apidocs -apiBasePath / -swaggerUiZipPath ../../../src/main/resources/swagger-ui.zip</additionalparam>

Override Model type returned by the REST method

If the REST method returns e.g. javax.ws.rs.core.Response wrapping the real response type and the model is not generated, it is possible to override the type that should be used for model generation in a dedicated conf file. It's a standard java properties file with mappings:

qualified method name=java type that should be used for model generation

e.g.

fixtures.sample.Service.getSubResourceWrappedInResponse(java.lang.String,java.util.List<fixtures.sample.model.SomeClass>)=fixtures.sample.SubResource
fixtures.sample.Service.otherMethod()=fixtures.sample.SomeOtherClass

Please notice there are NO white characters. The classes used for overriding MUST belong to the sources processed by this tool.

To activate this feature, -returnTypesOverrideMapping doclet option has to be used:

<additionalparam>-apiVersion 1 -docBasePath /apidocs -apiBasePath / -returnTypesOverrideMapping PATH_TO_CONF_FILE/CONF_FILE.properties</additionalparam>
