Не удалось получить конструктор для org.hibernate.persister.entity.SingleTableEntityPersister error

Question

Я не являюсь частым пользователем спящего режима. Я пытаюсь создать многозначное сопоставление, но я получаю ошибку (subj). Я искал ошибки в объявлениях классов, а также getter (последняя ошибка), но все кажется правильным. Кто-нибудь видит какие-либо ошибки в моем коде? Потому что я не могу понять.

Adres.java

package beans; 

public class Adres { 

    int id; 
    String adresas; 
    String adname; 

    public Adres() { 
    } 

    public int getId() { 
     return id; 
    } 

    public void setId(int id) { 
     this.id = id; 
    } 

    public String getAdresas() { 
     return adresas; 
    } 

    public void setAdresas(String adresas) { 
     this.adresas = adresas; 
    } 

    public String getAdname() { 
     return adname; 
    } 

    public void setAdname(String adname) { 
     this.adname = adname; 
    } 
} 

Men.java

package beans; 

public class Men { 

    int id; 
    String name; 

    Adres adres; 

    public Men() { 
    } 

    public int getId() { 
     return id; 
    } 

    public void setId(int id) { 
     this.id = id; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public Adres getAdd() { 
     return adres; 
    } 

    public void setAdd(Adres adres) { 
     this.adres = adres; 
    } 
}

Answer 1

Вы должны изменить геттер и сеттер для adresMen собственности в классе от

public Adres getAdd() { 
    return adres; 
} 

public void setAdd(Adres adres) { 
    this.adres = adres; 
} 

в

public Adres getAdres() { 
    return adres; 
} 

public void setAdres(Adres adres) { 
    this.adres = adres; 
} 

Предлагаю дать значащие имена переменных и связанные с ними геттеры, сеттеры!
