我一直在使用JPA和Spring，但在删除Entity方面遇到了问题。尝试删除以下实体结果失败，并在下面放置错误堆栈跟踪。我怀疑我必须对@JoinColumn注释中的字段做些什么，但是什么？
实体：
@Entity
public class Customers {
@Id
@GeneratedValue
private int id;
private String name;
private int age;
@Column(name="spend_money")
private Double spendMoney;
@OneToOne(cascade=CascadeType.ALL)
@JoinColumn(name="contact_id")
private Contacts contact;
@ManyToOne
@JoinColumn(name="country_id")
private Country country;
@OneToOne(cascade=CascadeType.ALL)
@JoinColumn(name="address_id")
private Address address;
@OneToMany(fetch = FetchType.EAGER, mappedBy="customer")
private Set<Purchase> purchases = new HashSet<Purchase>();
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 int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Double getSpendMoney() {
return spendMoney;
}
public void setSpendMoney(Double spendMoney) {
this.spendMoney = spendMoney;
}
public Contacts getContact() {
return contact;
}
public void setContact(Contacts contact) {
this.contact = contact;
}
public Country getCountry() {
return country;
}
public void setCountry(Country country) {
this.country = country;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
public Set<Purchase> getPurchases() {
return purchases;
}
public void setPurchases(Set<Purchase> purchases) {
this.purchases = purchases;
}
@Override
public String toString() {
return "Customers [id=" + id + ", name=" + name + ", age=" + age
+ ", spendMoney=" + spendMoney + ", contact=" + contact
+ ", country=" + country + ", address=" + address
+ ", purchases=" + purchases + "]";
}
}
地址实体：
@Entity
public class Address {
@Id
@GeneratedValue
private int id;
private String city;
@Column(name="postal_code")
private String postalCode;
private String street;
@ManyToOne
@JoinColumn(name="country_id")
private Country country;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getPostalCode() {
return postalCode;
}
public void setPostalCode(String postalCode) {
this.postalCode = postalCode;
}
public String getStreet() {
return street;
}
public void setStreet(String street) {
this.street = street;
}
public Country getCountry() {
return country;
}
public void setCountry(Country country) {
this.country = country;
}
@Override
public String toString() {
return "Address [id=" + id + ", city=" + city + ", postalCode="
+ postalCode + ", street=" + street + ", country=" + country
+ "]";
}
}
联系人实体：
@Entity
public class Contacts {
@Id
@GeneratedValue
private int id;
@Column(name="phone_number")
private String phoneNumber;
private String email;
@OneToOne
@JoinColumn(name="address_id")
private Address address;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
@Override
public String toString() {
return "Contacts [id=" + id + ", phoneNumber=" + phoneNumber
+ ", email=" + email + ", address=" + address + "]";
}
}
国家/地区实体：
@Entity
@Table(name="country")
public class Country {
@Id
@GeneratedValue
private int id;
@Column
private String country;
@OneToMany(fetch = FetchType.EAGER, mappedBy = "country")
private Set<Customers> customers = new HashSet<Customers>(0);
@OneToMany(fetch = FetchType.EAGER, mappedBy="country")
private Set<Address> addresses;
public Set<Customers> getCustomers() {
return customers;
}
public void setCustomers(Set<Customers> customers) {
this.customers = customers;
}
public Set<Address> getAddresses() {
return addresses;
}
public void setAddresses(Set<Address> addresses) {
this.addresses = addresses;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
@Override
public String toString() {
return "Country [id=" + id + ", country=" + country + "]";
}
}
Controller负责删除实体的方法：
@RequestMapping(value = "/user/remove/{id}")
public String removeUser(@PathVariable int id) {
Customers customer = customersDetailsDAO.getCustomer(id);
logger.info(Integer.toString(customer.getAddress().getId()));
customersDetailsDAO.removeCustomer(customer);
return "users";
}
和dao方法：
@Override
public void removeCustomer(Customers customer) {
em.remove(em.merge(customer));
}
