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

Question

I am trying to use embeddable annotation to store different values in one object to be persisted in one table.

I have two classes: 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. Address class which is embeddable class:

     @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; } 

   } this is my main class:

    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(); 

   }

I was trying to store the data but it was showing:

   ERROR: Field 'pincode' doesn't have a default value
   Exception in thread "main" org.hibernate.exception.GenericJDBCException:

I had pincode in my address but it was showing an error so i removed it but still it showing that error.

Please help me to solve it.

Answer 1

The table in your db has a field pincode for which you've not defined a default value and is not nullable. However, your entity has no mapping for that field and you are not sending a value for this field. Thus, java.sql.SQLException: Field 'pincode' doesn't have a default
value

Answer 2

1) Adapt your entity that it includes the field "pincode"

@Entity
@Table (name="UserDetails")
public class userDetails {
...
@Column(name="pincode", columnDefinition="Number(10) default '34562'")
int pincode;
...

2) or alter the underlying table so that the pincode field has a default value:

 ALTER TABLE user_details MODIFY pincode NUMBER(10) NULL DEFAULT NULL;

Number(10) is just chosen as an example. Replace this by the variable type of pincode.

Answer 3

I had same error as org.hibernate.exception.GenericJDBCException: could not execute statement where i forgot to initialize session factory.

Initializing(as follow) session factory resolved my issue.

@Autowired
private SessionFactory sessionFactory;

public void setSessionFactory(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}
