问题描述
在Spring + Hibernate 4.1应用程序中建立oneToMany关系时遇到一些问题
这是我的实体类。每个USER_ROLE记录都有FK到USER记录。我在互联网上找不到任何有用的东西。
I've got some problems with making oneToMany relation in Spring + Hibernate 4.1 application This is my entities classes. Every USER_ROLE record has FK to USER record. I can't find anything useful on the Internet.
@Entity
@Table( name = "USERS" )
public class User {
long id;
String login;
String password;
String name;
String surname;
GregorianCalendar birthDate;
String email;
GregorianCalendar joinDate;
String randomKey;
List<UserRole> userRoles = new ArrayList<UserRole>();
public User(){ } //JavaBean Hibernate requirement
@Id
@GeneratedValue(generator="increment")
@GenericGenerator(name="increment", strategy = "increment")
@Column(name="USER_ID", unique=true, nullable=false)
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
...
@OneToMany(mappedBy = "user", fetch = FetchType.LAZY)
public List<UserRole> getUserRoles() {
return userRoles;
}
public void setAccountRole(List<UserRole> aUserRoles) {
for (UserRole role : aUserRoles) {
this.addUserRole(role);
}
}
public void addUserRole(UserRole aRole) {
if (!this.userRoles.contains(aRole)) {
aRole.setUser(this);
this.userRoles.add(aRole);
}
}
}
@Entity
@Table(name = "USER_ROLE")
public class UserRole {
Integer roleId;
String role;
User user;
public UserRole() { }
// public UserRole(String role) {
// this.setRole(role);
// }
@Id
@GeneratedValue(generator="increment")
@GenericGenerator(name="increment", strategy = "increment")
@Column(name = "ROLE_ID", unique = true, nullable = false)
public Integer getRoleId() {
return roleId;
}
public void setRoleId(Integer roleId) {
this.roleId = roleId;
}
@Basic
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "USER_ID", nullable = false)
public User getUser() {
return user;
}
public void setUser(User aUser) {
this.user = aUser;
}
}
这是我的堆栈跟踪中的第一个例外:
And this is first exception in my stack trace:

推荐答案
我不使用Spring,而是使用hibernate 4.1.8,可以将其添加到hibernate.cfg.xml中:
I'm not using Spring and I'm using hibernate 4.1.8 and works adding to my hibernate.cfg.xml:
<property name="javax.persistence.validation.mode">none</property>
