From org.json JSONObject to org.codehaus.jackson

Question

I want to move from org.json to org.codehaus.jackson. How do I convert the following Java code?

private JSONObject myJsonMessage(String         


        

Answer 1

There is no JSONObject in Jackson api. Rather than returning a JSONObject, you can either return a Map or a Java Bean with message property that has getters and setters for it.

public class MyMessage {
    private String message;

    public void setMessage(final String message) {
        this.message = message;
    }

    public String getMessage() {
        return this.message;
    }
}

So, your method will be reduced to:

private MyMessage(String message) {
    MyMessage myMessage = new MyMessage();
    myMessage.setMessage(message);
    return myMessage;
}

Another aspect of this change would be changing the serialization code, to convert MyMessage back to json string. Jackson does Java Beans, maps by default, you don't need to create a JSONObject e.g.,

private String serializeMessage(MyMessage message){

    //Note: you probably want to put it in a global converter and share the object mapper
    ObjectMapper mapper = new ObjectMapper();
    return mapper.writeValueAsString(message);
}

The above will return {message: "some message"}

I have skipped the exceptions for brevity.
