Pretty print the JSON response

[devatherock]

Setting jackson.serialization.indent-output to true does not indent arrays. Need additional configuration to enable array indentation.

   @Singleton
    static class ObjectMapperBeanEventListener implements BeanCreatedEventListener<ObjectMapper> {

        @Override
        public ObjectMapper onCreated(BeanCreatedEvent<ObjectMapper> event) {
            final ObjectMapper objectMapper = event.getBean();
            DefaultPrettyPrinter prettyPrinter = new DefaultPrettyPrinter();
            prettyPrinter.indentArraysWith(DefaultIndenter.SYSTEM_LINEFEED_INSTANCE);
            objectMapper.setDefaultPrettyPrinter(prettyPrinter);

            return objectMapper;
        }
    }
