如何通过示例使用hibernate查询来搜索Id？ [英] how to search an Id using hibernate query by example?

问题描述

我有以下班级

hi i have the following class

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

我应该动态搜索多个字段
i通过示例发现了hibernate查询构造我的代码看起来像是一些东西

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();

当我在LabelName字段上搜索时，我得到确切的响应，当我试图通过ID搜索我得到意想不到的结果
i有goggled许多论坛我无法得到我想要的一些请帮助我
