使用Spring 3.x实现CORS

Question

I want to know what are the possible solutions for allowing Cross Origin Resource Sharing between my Website and API Server. And what will be the best approach?

Answer 1

These are the possible solutions:

1) Implement as it is implemented in Spring 4.2 using CORS Filter (Link for JIRA of this Feature https://jira.spring.io/browse/SPR-9278 and the implementation is here https://bitbucket.org/thetransactioncompany/cors-filter/src/cba65d9a30e1db457df57d7689dee3244026a916/src/main/java/com/thetransactioncompany/cors/?at=master )

2) By using Interceptor

3) Simply write a filter that adds cross origin headers in all servlet responses

4) Using JSONP as your data type in ajax request

I will prefer the first one.
