问题

hi i have the following class

public class Label
    {
    private Long TableId;
    private Long Id;
    private String LabelName;
    //getters and setters for corresponding fields
    }

i was supposed to search on multiple fields dynamically i came across hibernate query by example construct my code looks like some thing

Label bean =new Label();
if(Id!=null)
{
       bean.setId(Id);
}
if(LabeName!=null)
{
bean.setLabelName(LabelName)
}
    System.out.println(bean.toString());
            Example exampleObject=Example.create(bean).ignoreCase();
             criteria=currentSessionObj.createCriteria(Label.class).add(exampleObject);
             retObjects=criteria.list();

From the documentation
