Exposing ObjectMapper disables Spring Boot JacksonAutoConfiguration

[tchlyah]

Exposing ObjectMapper used by JsonSerializer implemented here: #1132, disables Spring Boot JacksonAutoConfiguration#jacksonObjectMapper(), since it is annotated with @ConditionalOnMissingBean.

It forces usage of Couchbase ObjectMapper Bean which disables Spring Boot Jackson customizations (properties, modules, ...).

seems that removing the @bean from couchbaseObjectMapper() would fix this.

[tchlyah]

Yes, is there any particular reason why we needed @Bean ?

[mikereiche]

The @bean is to expose the objectMapper. Is there some other way to do that? I suppose a user could override the couchbaseObjectMapper() in their Config class as follows, but this looks really ugly.

static ObjectMapper theObjectMapper;

@OverRide ObjectMapper couchbaseObjectMapper(){
theObjectMapper = super.couchbaseObjectMapper();
return theObjectMapper;
}

which disables Spring Boot Jackson customizations (properties, modules, ...)

The purpose of exposing the ObjectMapper was to allow it to be customized.

Overriding couchbaseObjectMapper() is definitely better than exposing bean. The couchbaseObjectMapper() is only called once right? There is no need to use static property.

[mikereiche]

Right. Not sure what I was thinking.

@OverRide ObjectMapper couchbaseObjectMapper(){
theObjectMapper = super.couchbaseObjectMapper();
theObjectMapper... // customizations
return theObjectMapper;
}
