Class ProxyingHandlerMethodArgumentResolver

java.lang.Object

org.springframework.web.method.annotation.ModelAttributeMethodProcessor

org.springframework.data.web.ProxyingHandlerMethodArgumentResolver

All Implemented Interfaces:

Aware, BeanClassLoaderAware, BeanFactoryAware, HandlerMethodArgumentResolver, HandlerMethodReturnValueHandler

public class ProxyingHandlerMethodArgumentResolver
extends ModelAttributeMethodProcessor
implements BeanFactoryAware, BeanClassLoaderAware

HandlerMethodArgumentResolver to create Proxy instances for interface-based controller method parameters. Resolution requires the method parameter or its interface type to be annotated with ProjectedPayload.

By default, data binding for collection properties is limited to 1024 elements. This limit can be overridden by setting the "spring.data.web.projection.collection-limit" Spring property.

Since:

1.10
