Cross-Origin Resource Sharing (CORS) is an HTTP-header based mechanism that allows a server to indicate any other origins (domain, scheme, or port) than its own from which a browser should permit loading of resources. CORS also relies on a mechanism by which browsers make a “preflight” request to the server hosting the cross-origin resource, in order to check that the server will permit the actual request. In that preflight, the browser sends headers that indicate the HTTP method and headers that will be used in the actual request.
In the recent version of spring boot, handling cors error is a bit challenge. cors filter and cors configuration is not a straightforward thing to handle in microservices. Setting up allowed origin wildcard for multiple origin is required most of the time.
In this quick tutorial, I have shared the source code which works for any kind of spring project to bypass the cors obstacle. You can set your custom origin altering the file or append when an origin is missing and how the configuration works.
