How will I configure jackson to use snake case in dropwizard instead of putting @JsonSnakeCase in every class ?

回答1:

And finally am able to find the answer.. Just add below cofiguration.

environment.getObjectMapperFactory().setPropertyNamingStrategy(PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES)

Just add this following line in your run() method

environment.getObjectMapper().setPropertyNamingStrategy(
        PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);

回答3:

environment.jersey().register(new JacksonMessageBodyProvider(mapper));
