How to convert Java class to map

To convert class to map in Java you can use the ObjectMapper by the Jackson library. First declare the class model.

class MyClass {
    public int myValue;
    public String myUser;

And then do the convertion.

MyClass obj = new MyClass();
obj.myValue = 1;

ObjectMapper mapObject = new ObjectMapper();
Map <String, Object> mapObj = mapObject.convertValue(obj, Map.class);
