Customizing Swagger 2 RESTful API Documentation


Swagger 2 is very flexible to customize our RESTful API documentation information like title, description, contact details, etc.  Swagger 2 provides the ApiInfo class which helps to customize the API metadata and Contact class for contact details in springfox.documentation.service package. To learn more about API documentation, refer our Spring Boot + Swagger 2 API Documentation example.

By default, Swagger 2 gives you the following info:

public static final Contact DEFAULT_CONTACT = new Contact("", "", "");
public static final ApiInfo DEFAULT = new ApiInfo("Api Documentation", "Api Documentation", "1.0", "urn:tos",
          DEFAULT_CONTACT, "Apache 2.0", "http://www.apache.org/licenses/LICENSE-2.0");

which results looks like on your API documentation web page as follow:

And to for customizing the information, edit the above information and add it to your Swagger2Config file as given below:

apiInfo(ApiInfo apiInfo) method – Sets the API’s meta information as included in the JSON ResourceListing response.

Swagger2Config.java
package org.websparrow.swagger.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class Swagger2Config {

	@Bean
	public Docket empApiDoc() {
		return new Docket(DocumentationType.SWAGGER_2).select()
				.apis(RequestHandlerSelectors.basePackage("org.websparrow.controller")).
				build().apiInfo(NEW_API_INFO);
	}

	public static final Contact NEW_CONTACT_DETAILS = new Contact("Websparrow.org Team", "https://www.websparrow.org/",
			"websparrow.org@gmail.com");

	public static final ApiInfo NEW_API_INFO = new ApiInfo("Employee RESTful API Documentation",
			"This RESTful service produces the employee deatils in JSON formats.", "1.0",
			"https://www.websparrow.org/terms-of-service", NEW_CONTACT_DETAILS, "Apache 2.0",
			"http://www.apache.org/licenses/LICENSE-2.0");
}

The above customization results look like on Swagger UI as follow:

Note: You can also use the ApiInfo class constructor for metadata customization but it is deprecated since 2.4.0 version.

@Deprecated
  public ApiInfo(
      String title,
      String description,
      String version,
      String termsOfServiceUrl,
      String contactName,
      String license,
      String licenseUrl) {
    this(title, description, version, termsOfServiceUrl, new Contact(contactName, "", ""), license, licenseUrl);
  }
