jackson change field name when convert java object to json

[Phil Zhang]

I met a strange issue, I have a class and it has two usernames, so I call them aName and bName, such as:

public class Member{

    private String aName;

    private String bName;

}

But when jackson convert this to a json response, it will change field name to aname and bname, is this a feature or can I avoid this by configuration?

What exactly are you doing? Please show the code, including configuration of ObjectMapper (and full class declaration). Class definition alone does not really show what is happening unfortunately.
