I'm trying to configure Jackson to show JSR 310 instants in ISO 8601 format.
@Configuration
class Jackson {
@Bean
static ObjectMapper objectMapper() {
ObjectMapper objectMapper = new ObjectMapper().findAndRegisterModules();
objectMapper.disable( SerializationFeature.WRITE_DATES_AS_TIMESTAMPS );
return objectMapper;
}
}
However this is not a unique Bean, and realistically I only would like to disable this one setting. So I'm not really wanting to create ObjectMapper, so much as specify a single setting on it.

and the output of my controller that has an Instant in a Greeting DTO.
{"content":"Hello, \"me\"","time":1443886979.716000000}
How can I reconfigure just this one setting on the default object mapper?
You can (and probably should) you RepositoryRestConfigurerAdapter
(in Spring Data Rest 2.4) or RepositoryRestMvcConfiguration
which expose the configureObjectMapper
method.
@Configuration
class RepositoryRestAdapterConfiguration extends RepositoryRestConfigurerAdapter {
@Override
public void configureJacksonObjectMapper(ObjectMapper objectMapper) {
objectMapper.registerModule(new JavaTimeModule());
objectMapper.disable( SerializationFeature.WRITE_DATES_AS_TIMESTAMPS );
}
}
