如何在spring-boot中启用跨域微服务

Question

I have nearly 5 spring boot applications which are connected to discovery service to communicate with each other. and also I want to expose some controllers to the public, so how can I enable cross-origin? should I do it in all controller level or from discovery? Any other suggestion Please!

Answer 1

Use the @CrossOrigin annotation either on your controller classes or on each of your controller methods that you want to permit.

You can also create a WebMvcConfigurer Bean in one of your configuration classes where you can establish cross origin configuration at a global level.

Edit: I like @peekay suggestion as well.

Answer 2

I have used Kong Api Gateway in front of all services. To enable cross origin.its very easy to do it in single place rather than in every single controller
