```
@Bean
public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
Jackson2ObjectMapperBuilderCustomizer cunstomizer = new Jackson2ObjectMapperBuilderCustomizer() {

@Override
public void customize(Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {

jacksonObjectMapperBuilder.serializerByType(Instant.TYPE, ……);
jacksonObjectMapperBuilder.serializerByType(Instant.class, ……);

}
};
return cunstomizer;
}
