JCGs (Java Code Geeks) is an independent online community focused on creating the ultimate Java to Java developers resource center; targeted at the technical architect, technical team lead (senior developer), project manager and junior developers alike. Next, we're going to create another resource on our server which is accessed via a POST and receives a parameter in the body, so interceptors will be executed when accessing it: @POST @Path("/custom") public Response getCustomGreeting(String name) { return Response.status(Status.OK.getStatusCode()) .build(); } For conveniece, we have a fat jar whose start class is com.javacodegeeks.example.Main. In this blog post, we will be looking at how we can control the JSON response by customizing the status code in ASP.NET Core.
