I was successfully using @EnableSpringDataWebSupport in my Spring Boot app to enable pagination, sorting and stuff. However, at some point, I had to introduce a custom argument resolver and did it with Java config as follows:
@Configuration
@EnableSpringDataWebSupport
public class MvcConfig extends WebMvcConfigurerAdapter {
@Override
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
argumentResolvers.add(renamingProcessor());
}
@Bean
protected RenamingProcessor renamingProcessor() {
return new RenamingProcessor(true);
}
}
It made my new argument resolver work, however completely broke paging and other features, that were automatically configured by @EnableSpringDataWebSupport. I've tried switching WebMvcConfigurerAdapter to alternatives like DelegatingWebMvcConfiguration or WebMvcConfigurationSupport, but no luck -- pagination fails with the exception:
Failed to instantiate [org.springframework.data.domain.Pageable]: Specified class is an interface
I would appreciate any help or advice how to handle this issue. Similar questions didn't help a lot:
So, after some investigation, I figured out the solution (perhaps, not ideal one, but still working -- I'd still be happy to see the "right" resolution for the problem from Spring professionals). What I changed is switching from extends WebMvcConfigurerAdapter to extends HateoasAwareSpringDataWebConfiguration (since we're using HATEOAS). I also updated the overridden addArgumentResolvers and now my MvcConfig looks like this:
@Configuration
public class MvcConfig extends HateoasAwareSpringDataWebConfiguration {
@Override
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
super.addArgumentResolvers(argumentResolvers);
argumentResolvers.add(renamingProcessor());
}
@Bean
protected RenamingProcessor renamingProcessor() {
return new RenamingProcessor(true);
}
}
The issue with Pageable disappeared, and custom RenamingProcessor works like a charm.
Hope this answer will help someone who's facing similar issue.
