尝试从控制器更新实体时，我不断收到此异常。请放心，已经对这个例外进行了彻底的研究，但在我的情况下，这些建议都没有奏效。
我正在尝试通过调用 hibernate 来更新医生实体session.update(entity)；
Doctor model:
@Entity
@Table(name = "tbl_doctor")
public class Doctor {
private Long id;
private PersonInfo personInfo;
private String licenseNumber;
private User user;
private String specialization;
private String employmentStatus;
private String suffix;
private List<Patient> patients;
//
// @OneToMany
// @JoinTable(name = "Doctor_Appointment", joinColumns = { @JoinColumn(name
// = "doctor_id") }, inverseJoinColumns = { @JoinColumn(name = //
// "appointment_id") })
// private List<Appointment> appointments;
public Doctor() {
super();
user = new User();
personInfo = new PersonInfo();
}
@Override
public String toString() {
String patients= "";
for(Patient p: this.patients) {
patients += p.toString();
}
return "Doctor [id=" + id + ", personInfo=" + personInfo
+ ", licenseNumber=" + licenseNumber + ", user=" + user
+ ", specialization=" + specialization + ", employmentStatus="
+ employmentStatus + ", suffix=" + suffix + ", patients="
+ patients + "]";
}
@Column(name = "fld_license_number")
public String getLicenseNumber() {
return licenseNumber;
}
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "key_user")
public User getUser() {
return user;
}
@Column(name = "fld_specialization")
public String getSpecialization() {
return specialization;
}
@Column(name = "fld_employment_status")
public String getEmploymentStatus() {
return employmentStatus;
}
@Column(name = "fld_suffix")
public String getSuffix() {
return suffix;
}
@OneToMany(cascade = CascadeType.ALL)
@JoinColumn(name = "key_patient")
@Fetch(value = FetchMode.SUBSELECT)
public List<Patient> getPatients() {
return patients;
}
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "key_doctor")
public Long getId() {
return id;
}
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "key_person_info")
public PersonInfo getPersonInfo() {
return personInfo;
}
//setters
}
个人信息仅包括名字、姓氏、性别、生日等生物数据。
控制器
@RequestMapping(value="/update_doctor.it", method=RequestMethod.POST)
public String updateDoctor(HttpSession session, @ModelAttribute("doctor") Doctor doctor, Model model, @RequestParam("id") long adminId) {
System.err.println("update doctor controller");
String username = session.getAttribute("user").toString();
session.setAttribute("user", username);
doctor.getUser().setEnabled(true);
doctor.getPersonInfo().setDateModified(LocalDate.now());
doctorDao.updateDoctor(doctor);
return "redirect:/view_doctor_profile.it?id=" + doctor.getId();
}
道实现
@Override
public void updateDoctor(Doctor doctor) {
Session session = sessionFactory.getCurrentSession();
session.update(doctor);
}
