org.hibernate.exception.GenericJDBCException：无法在休眠中执行语句

Question

我正在尝试使用可嵌入的注释将不同的值存储在一个对象中，以将其保留在一张表中。

我有两个类：userDetails：

package org.hibernet.src;
@Entity
@Table (name="UserDetails")
 public class userDetails {
 @Id 
@GeneratedValue(strategy = GenerationType.AUTO)
private int userId;
@Temporal(TemporalType.DATE)
private Date dob;
public Date getDob() {
    return dob;
}
public void setDob(Date dob) {
    this.dob = dob;
}
private String userName;
@Embedded
private Address address;

public Address getAddress() {
    return address;
}
public void setAddress(Address address) {
    this.address = address;
}
public int getUserId() {
    return userId;
}
public void setUserId(int userId) {
    this.userId = userId;
}
public String getUserName() {
    return userName;
}
public void setUserName(String userName) {
    this.userName = userName;
}

}

2. 地址类是可嵌入的类：

    @Embeddable
   
    public class Address {
   
   @Column(nullable=true)
   private String street;
   
   @Column(nullable=true)
   private String city;
   
    @Column(nullable=true)
    private String state;
   
   
   public String getStreet() {
   return street;
   }
   public void setStreet(String street) {
   this.street = street;
   }
   public String getCity() {
       return city;
   }
    public void setCity(String city) {
       this.city = city;
    }
   public String getState() {
   return state;
   }
   public void setState(String state) {
       this.state = state;
   }
   

   这是我的主要课程：

   public static void main(String[] args) {
   
   userDetails user = new userDetails();
   Address add = new Address();
   
   user.setUserName("Dipesh");
   user.setDob(new Time(0));
   add.setCity("vadodara");
   add.setState("gujarat");
   add.setStreet("raopura");
   
   
   
   SessionFactory sessionfactory = new     
    Configuration().configure().buildSessionFactory();
   Session session = sessionfactory.openSession();
   session.beginTransaction();
   session.save(user);
   session.save(add);
   /*user = (userDetails)session.get(userDetails.class, 6);*/
   
   session.getTransaction().commit();
   session.close();
   

   }

我试图存储数据，但显示如下：

我在地址中输入了密码，但它显示了错误，因此我删除了它，但仍然显示该错误。

请帮我解决。

数据库中的表具有字段密码，您尚未为其定义默认值并且不能为空。但是，您的实体没有该字段的映射，并且您没有为此字段发送值。因此，java.sql.SQLException：字段“密码”没有默认
值
