How can I use Jackson for JSON serialization in Java?

How can I use Jackson for JSON serialization in Java?

You can use Jackson by adding the Jackson library to your project and then using the ObjectMapper class to serialize objects.

Can you show me a simple example of serializing a Java object?

Sure! Here's a basic example:

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) throws Exception {
        ObjectMapper objectMapper = new ObjectMapper();
        MyClass obj = new MyClass("example", 123);
        String jsonString = objectMapper.writeValueAsString(obj);
        System.out.println(jsonString);
    }
}

What if my object has nested objects?

Jackson handles nested objects automatically. Just ensure your classes are properly defined with getters and setters.

Are there any common issues I should be aware of?

Yes, common issues include missing getters/setters, circular references, and not including the Jackson annotations when needed.
