Class ContentTypeInterceptor

java.lang.Object

org.springframework.web.servlet.handler.HandlerInterceptorAdapter

org.springframework.batch.admin.web.interceptor.ContentTypeInterceptor

All Implemented Interfaces:

Aware, BeanFactoryAware, AsyncHandlerInterceptor, HandlerInterceptor

public class ContentTypeInterceptor
extends HandlerInterceptorAdapter
implements BeanFactoryAware

Interceptor that looks for an extension on the request path and adds it to the view name if it matches a list provided. This can be used to do simple content negotiation based on request path extensions, as is usual with browsers (the view that is finally resolved could have a different content type than the original request).
