Java 在类上找不到适当的构造函数

我试图将本机SQL结果映射到POJO，但它返回了一个错误。 以下是完整的堆栈跟踪：

以下是我的会员服务实现：

@Transactional
@SuppressWarnings("unchecked")
public List<Members> findByMembername(String memberName) 
{
    //return membersDao.findByMemberName(memberName);
     List<Members> members = null;
    try {
         session = HibernateUtil.getSessionFactory().openSession();
         transaction = session.beginTransaction();

      // Native query selecting all columns
         Query query = session.createNativeQuery("SELECT * FROM members_tb where memberName like :memberName","MemberMapping")
                 .setParameter("memberName","%"+memberName+"%"); //named parameter binding 
                members = query.getResultList();
         transaction.commit(); 
      } catch (Exception e) {
         e.printStackTrace();
      } finally {
         if (session != null) {
            session.close();
         }
      }
     // HibernateUtil.shutdown();
      return members;
}   

@Transactional
@抑制警告（“未选中”）
公共列表FindBymerName（字符串memberName）
{
//返回membersDao.FindBymerName（memberName）；
列表成员=null；
试一试{
session=HibernateUtil.getSessionFactory（）.openSession（）；
事务=session.beginTransaction（）；
//选择所有列的本机查询
Query Query=session.createNativeQuery（“从成员中选择*_tb，其中memberName类似于：memberName”、“MemberMapping”）
.setParameter（“memberName”、“%”+memberName+“%”；//命名参数绑定
members=query.getResultList（）；
commit（）；
}捕获（例外e）{
e、 printStackTrace（）；
}最后{
if（会话！=null）{
session.close（）；
}
}
//HibernateUtil.shutdown（）；
返回成员；
}   

请问如何消除错误并设计合适的构造函数？？？

如果我不需要将每一列都加载到构造函数中，尽管我希望所有列都映射到结果中，那么可能是这样的。

您必须为此创建一个构造函数

---

在使用了

sqlresultsmapping

的类中创建构造函数，并将构造函数中的变量保持在与在

sqlresultsmapping

中保持的顺序相同的顺序中。列出的列与构造函数参数的顺序不同

Parameters                  Columns
=========================   ==================
Long   memberId             memberId
Long   dcaRegno             dcaRegno
String memberName           address
Long   memberMobileNum      age
Long   memberHomePhoneNum   areaId
String memberEmail          birthday
String gender               cellId
String department           dca
String address              department
Long   cellId               editor
Long   areaId               firstTime
String maritalStatus        gender
String age                  maritalStatus
String birthday             memberEmail
String firstTime            memberHomePhoneNum
String secondTime           memberMobileNum
String dca                  memberName
String note                 note
String editor               secondTime

---

请在pojo类中创建此构造函数。因为我可以看到构造函数之间不匹配

成员（长memberId、长dcaRegno、字符串地址、字符串年龄、长areaId、字符串生日、长cellId、字符串dca、字符串部门、字符串编辑器、字符串第一次、字符串性别、字符串maritalStatus、字符串成员电子邮件、长成员HomePhoneNum、长成员MobileNum、字符串成员名称、字符串注释、字符串第二次）

希望这对你有用
