Class AnnotationMethodHandlerAdapter.RequestSpecificMappingInfoComparator

java.lang.Object

org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter.RequestSpecificMappingInfoComparator

All Implemented Interfaces:

java.util.Comparator<AnnotationMethodHandlerAdapter.RequestSpecificMappingInfo>

Enclosing class:

AnnotationMethodHandlerAdapter

static class AnnotationMethodHandlerAdapter.RequestSpecificMappingInfoComparator
extends java.lang.Object
implements java.util.Comparator<AnnotationMethodHandlerAdapter.RequestSpecificMappingInfo>

Comparator capable of sorting AnnotationMethodHandlerAdapter.RequestSpecificMappingInfos (RHIs) so that sorting a list with this comparator will result in:

• RHIs with better matched paths take precedence over those with a weaker match (as expressed by the path pattern comparator.) Typically, this means that patterns without wild cards and uri templates will be ordered before those without.
• RHIs with one single request method will be ordered before those without a method, or with more than one method.
• RHIs with more request parameters will be ordered before those with less parameters
