我已經嘗試了一些在網絡上找到的解決方案，他們都沒有工作。我正在使用內存中的持久化hibernate數據庫。org.h2.jdbc.JdbcSQLException：NULL不允許列「ID」
@Entity
@Table(name = "Users")
public class User implements Serializable {
private String id;
private String username;
private String password;
private String email;
private Boolean enabled;
private Event checkedInEvent;
@Id
@GeneratedValue(generator="uuid", strategy = GenerationType.AUTO)
@GenericGenerator(name = "uuid", strategy = "uuid2")
@Column(name = "id", unique = true)
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
@Column(name = "username")
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@Column(name = "password")
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@PrePersist
public void encryptPassword() throws Exception {
MessageDigest md = MessageDigest.getInstance("MD5");
md.update(password.getBytes());
byte byteData[] = md.digest();
//convert the byte to hex format method 1
StringBuffer sb = new StringBuffer();
for (int i = 0; i < byteData.length; i++) {
sb.append(Integer.toString((byteData[i] & 0xff) + 0x100, 16).substring(1));
}
password = sb.toString();
}
@Column(name = "email")
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Column(name = "enabled")
public Boolean getEnabled() {
return enabled;
}
public void setEnabled(Boolean enabled) {
this.enabled = enabled;
}
@PostLoad
public void postLoad()
{
password = null;
}
@ManyToOne(optional=true,cascade=CascadeType.ALL)
@JoinTable
(
name="CheckedInUsers",
joinColumns={ @JoinColumn(name="checkedInUsersId", referencedColumnName="id") },
inverseJoinColumns={ @JoinColumn(name="checkedInEventsId", referencedColumnName="id") }
)
public Event getCheckedInEvent() {
return checkedInEvent;
}
public void setCheckedInEvent(Event checkedInEvent) {
this.checkedInEvent = checkedInEvent;
}
}
經過在用戶

將被持久保存的數據
user = new User();
user.setUsername("billTheTester");
user.setEmail("[email protected]");
user.setPassword("test123");
user = daoManager.getUserRepo().save(user);
this.testUserTwo = user;
Calendar cal = Calendar.getInstance();
Event event = new Event();
event.setName("Hanging Out!");
event.setVenue(venue);
event.setStartTime(cal.getTime());
event = daoManager.getEventRepo().save(event);
testUserTwo.setCheckedInEvent(event);
daoManager.getUserRepo().save(testUserTwo);

添加將保留一些數據的代碼。 –
已被添加。謝謝 – numerical25
另外，添加h2的配置.. –
