Swagger UI 2.0 CORS Issue While Accessing Salesforce REST API using Spring Boot

Hello All,

I am trying to create salesforce REST API documentation using Spring Boot. I have created swagger.yaml files in my SpringBoot, I am able to get swagger UI html using it but when it comes to try out , I am getting below error while access the salesforce APIs.

 

Error:

Access to fetch at 'https://login.salesforce.com/services/oauth2/token' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
