Spring Framework does not use Jackson for web bindings (but use it, as you've found out yourself for the body of the request and the response). Having a converter using Jackson could be problematic as you need to know for sure when you can actually call it (vs. a more specific converter).The ArangoConfiguration provides a convenient way to register Spring Converter by implementing the method customConverters(). Examples @Configuration public class MyConfiguration implements ArangoConfiguration { @Override protected Collection<Converter<?, ?>> customConverters() { return Arrays.asList(new MyConverter()); } } Converter SPI is pretty simple, you just implement the interface: Converter<FromClass, ToClass> and register it. But the sole convert method it declares passes only the FromClass in and expects you to derive a ToClass. Thus no passing in Enum<?> or something like that. I thought maybe property editors provide a different way of handling things.Since JPA 2.1, you can use an AttributeConverter to implement a custom mapping for your enums. It allows you to implement the conversion between a Java type and its database representation. You can use it to convert all basic attributes defined by entity classes, mapped superclasses, or embeddable classes.The simplest way to configure the mapper is via application properties. The general structure of the configuration is as follows: spring.jackson.<category_name>.<feature_name>=true, false. As an example, if we want to disable SerializationFeature. WRITE_DATES_AS_TIMESTAMPS, we'll add: spring.jackson.serialization.write-dates-as-timestamps=false.Summary. In this spring boot example, we will see primarily two major validation cases -. HTTP POST /employees and request body does not contain valid values or some fields are missing. It will return HTTP status code 400 with proper message in response body. HTTP GET /employees/ {id} and INVALID ID is sent in request.Here we will see how we can use this inside our spring boot application to validate the controller's request object. 1.
