Disable DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, jackson-datatype-jdk8:support for other Java 8 types like Optional, jackson-datatype-jsr310:support for Java 8 Date and Time API types, jackson-datatype-joda:support for Joda-Time types, jackson-module-kotlin:support for Kotlin classes and data classes. While Java SE does not provide extensive support for converting JSON to Java objects or the other way around, we have third party libraries like Jackson to take care of this for us. While you could retrieve the result, save it as a String and then convert using the readValue() method - you can directly read the HTTP response, given a URL, and deserialize it to the desired class: With this approach, you can skip the intermediary String, and directly parse HTTP request results! Implementations of this interface perform the actual work of mapping each row to a result object.

Then, we'll take a look at the Tree Model for parsing arbitrary structures, followed by customization flags and writing custom serializers and deserializers. The FAIL_ON_EMPTY_BEANS serialization feature defines what happens when no accessors (properties) for a type are found. In this context, the @JsonAlias would serve as alternative names to be accepted besides the enforced property name, and you can even supply a list to the annotation: Now, any of the aliases would get mapped to the same property, but when serializing, the @JsonProperty value would be used.
