RequestedContentTypeResolverBuilder (Spring Framework 5.2.12.RELEASE API)

java.lang.Object
- org.springframework.web.reactive.accept.RequestedContentTypeResolverBuilder

```
public class RequestedContentTypeResolverBuilder
extends Object
```
Builder for a composite RequestedContentTypeResolver that delegates to other resolvers each implementing a different strategy to determine the requested content type -- e.g. Accept header, query parameter, or other.
Use builder methods to add resolvers in the desired order. For a given request he first resolver to return a list that is not empty and does not consist of just MediaType.ALL, will be used.
By default, if no resolvers are explicitly configured, the builder will add HeaderContentTypeResolver.
