I am trying to convert java object to JSON object in Tomcat/jersey using Jackson. And want to suppress serialization(write) of certain properties dynamically.

I can use JsonIgnore, but I want to make the ignore decision at runtime. Any ideas??

So as an example below, I want to suppress "id" field when i serialize the User object to JSON..

new ObjectMapper.writeValueAsString(user);


class User {

private String id = null;
private String firstName = null;
private String lastName = null;

//getters
//setters

}//end class
