how to convert complex generic type?

Is there a demo to explain how to convert complex generic type data?
data type for instance,

public class DataObject {

private String status;

private String errorCode;

private String message = "";

private String type;

private T data;

private PageInfo page;
}

public class PageInfo {

private int page = 1;

private int pageSize = 10;

private int total;

private int maxPage;

private List items;
}

Start by reviewing LoganSquare's existing documentation and examples for generic type conversion, then use the DataObject and PageInfo shapes in the issue as the example case. Done means providing a clear, working demonstration of converting this nested generic data, with any relevant usage details documented.
