Make spring-hateoas-webmvc module compatible with spring-hateoas 1.3.4

See original GitHub issue

Hi,

While upgrading to spring boot 2.5.5, I’m facing the following exception:

java.util.NoSuchElementException: null
	at java.base/java.util.Arrays$ArrayItr.next(Arrays.java:4431)
	at org.springframework.hateoas.server.mvc.WebMvcLinkBuilderFactory.lambda$linkTo$1(WebMvcLinkBuilderFactory.java:128)

	at org.springframework.web.method.support.HandlerMethodArgumentResolverComposite.resolveArgument(HandlerMethodArgumentResolverComposite.java:121)

This is probably related to a change in spring-hateoas 1.3.4, I think introduced by https://github.com/spring-projects/spring-hateoas/issues/1589 Could you please have a look? Thanks!

Happy to help! At first glance, it’s weird that you apparently don’t hand in parameter values for a target controller method that actually takes parameters. We could of course default to assume null for the ones missing but it feels like this would mask issues better solved on the call side?

Hey @odrotbohm,

thanks for the quick action and nice to hear that this is fixed in 1.4. I’ll add this “workaround” 😃
