Java StdSubtypeResolver-class And Method Code Example

Here is an example of using the StdSubtypeResolver class in the com.fasterxml.jackson.databind package in Java:

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.jsontype.impl.StdSubtypeResolver;

public class Example {
    public static void main(String[] args) throws Exception {
        ObjectMapper mapper = new ObjectMapper();
        StdSubtypeResolver subtypeResolver = new StdSubtypeResolver();
        // Register subtypes
        subtypeResolver.registerSubtypes(MySubType1.class, MySubType2.class);

class MySubType1 {

class MySubType2 {

This example creates an instance of the ObjectMapper class, which is used to convert between Java objects and JSON. It also creates an instance of the StdSubtypeResolver class and sets it to the ObjectMapper. With this, the StdSubtypeResolver can be used to find the subtypes of a given class.

In this example, the registerSubtypes method is used to register MySubType1 and MySubType2 as subtypes of the class passed to it. This means that instances of these classes will be treated as subtypes of the class passed to the registerSubtypes method when deserializing or serializing JSON.

With this example, you can see how you can use the StdSubtypeResolver to register subtypes and use it in the deserialization and serialization process with ObjectMapper.
