Spring-boot: Custom WebMvcConfiguration breaks Jackson formatting

[creactiviti]

I'm using Spring Boot 2.0.0.RELEASE.

I have the following configuration to proxy some static content:

@Configuration
class WebMvcConfiguration extends WebMvcConfigurationSupport {

  @Value("${my.url}")
  private String myUrl;

  @Override
  protected void addResourceHandlers(ResourceHandlerRegistry aRegistry) {
    aRegistry.addResourceHandler("/some/path/**").addResourceLocations(myUrl);
  }
}

But that seems to break my Jackson config:

spring.jackson.date-format=yyyy-MM-dd'T'HH:mm:ss'Z'
spring.jackson.serialization.write-date-keys-as-timestamps=false

on my controllers. i.e. dates are coming as long timestamps as opposed to formatted.

Spring Boot is taking your use of WebMvcConfigurationSupport as an indication that it shouldn't auto-configure Spring MVC. Try replacing extends WebMvcConfigurationSupport with implements WebMvcConfigurer instead.

This feature took me whole day to find out why my Jackson setting not work :(

Maybe we should add some doc in the class or some warning about it.
