This is similar to accepted solution by @rick.

If you don't want to touch existing message converters configuration you can just declare a Jackson2ObjectMapperBuilder bean like:

@Bean
public Jackson2ObjectMapperBuilder configureObjectMapper() {
    return new Jackson2ObjectMapperBuilder()
        .modulesToInstall(Hibernate4Module.class);
}

Do not forget to add the following dependency to your Gradle file (or Maven):

compile 'com.fasterxml.jackson.datatype:jackson-datatype-hibernate4:2.4.4'

Useful if you have a spring-boot application and you want to keep the ability to modify Jackson features from application.properties file.
