There is a Maven dependency required to have the SpringFox implementation of the Swagger 2 specification in your Account microservice project:

<dependency> 
   <groupId>io.springfox</groupId> 
   <artifactId>springfox-swagger2</artifactId> 
   <version>${swagger.version}</version> 
</dependency>

In the preceding Maven dependency, we have added the SpringFox Maven dependency for Swagger 2 with groupId io.springfox and the springfox-swagger2 artifact ID. Let's configure Swagger using the following configuration:

<properties> 
   ... 
   <swagger.version>2.7.0</swagger.version> 
</properties> 

After adding the Swagger 2 dependency with our example of the Account microservice, let's integrate the Swagger 2 configuration.
