I have an API running on Spring Boot and I want to access the data using http call from AngularJS. But it is giving me the error
XMLHttpRequest cannot load http://localhost:9000/transaction-service/transaction/query?id=800103209000150247301466600013. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access.
I know it has something to do with the headers but I don't know how to do it.
