Я хотел бы настроить свои запросы с помощью CrudRepository:
Это мой код:
@Repository
public interface CustomerRepository extends CrudRepository<Customer, Long> {
@Query("UPDATE customer c SET c.firstName = :firstName WHERE c.id = :id")
Integer setNewFirstNameForId(@Param("firstName") String firstName, @Param("id") long id);
}
@Entity
public class Customer {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private long id;
private String firstName;
private String lastName;
protected Customer() {}
public Customer(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
@Override
public String toString() {
return String.format(
"Customer[id=%d, firstName='%s', lastName='%s']",
id, firstName, lastName);
}
Но, когда я компилирую все это, у меня есть эта ошибка: "Ошибка при создании bean с именем" customerRepository ": вызов метода init не удался;...
Спасибо заранее,
изменить:
Это моя ошибка:
