What it means is you may have other dependencies on Jackson, and the SDK will still work. The latest release supports Jackson 2.10-2.13.
#Java jackson annotations how to
Here are a couple of options on how to handle Jackson when the API and Java code are not perfectly aligned. The specific version of Jackson depends on the azure-sdk version you are using. In addition to JsonCreator, there are a lot of other Jackson annotations that will make your programming. The way to handle that will differ for different projects but here I want to present a few options on how to manage json while using Java interfaces.ĪPI design should not depend on the implementation technology and the best practices of interfaces and polymorphism in Java should not be abandoned into order to use an API. JsonCreator Jackson Annotation Example in Java. Using Java and json can be difficult since one requires strong typing and predefined data structure but the other allows massive amounts of flexibility. The JsonAppend annotation is used to add virtual properties to an object in addition to regular ones when that object is serialized. My view is that custom deserialisation is a last resort, we should try to use annotations and keep the project simple and use custom code to solve problems that we cannot do another way. The downside is that we need to write more code with will become complex in a large project. We could even be returning an anonymous class here and not create an implementation at all if we wanted to. Using this method we could decouple the code from the json body completely as well as parse data types that would otherwise be impossible. Now whenever Jackson needs to handle an instance of MyInterface it will use the custom deserializer. class, new MyInterfaceDeserialize ()) objectMapper. SimpleModule deserialization = new SimpleModule () deserialization. We need to register this deserializer with Jackson. PROPERTY, property = "type", defaultImpl = MyInterfaceImpl. To map ownerName, we unpack the nested owner object to a Map and extract its name property. Package import .JsonSubTypes import .JsonTypeInfo ( use = JsonTypeInfo. To map the nested brandName property, we first need to unpack the nested brand object to a Map and extract the name property.
