spring と hibernate を使用して DB に新しいユーザーを保存しようとするたびに、この例外がポップアップし続けるのはなぜかと頭を悩ませています。
@Entity アノテーションが存在することを再確認し、@Table アノテーションを追加して、このオブジェクトがどのテーブルに属しているかを確認しましたが、まだこのエラーが発生しています
以下は私のユーザーオブジェクトです:
@Entity
@Table(name = "USER")
public class User implements Serializable {
/**
* Serial version
*/
private static final long serialVersionUID = 1L;
@JsonElement(type = JsonElementType.JSON_KEY)
public static final String KEY_BIO = "Bio";
@JsonElement(type = JsonElementType.JSON_KEY)
public static final String SURNAME = "Surname";
@JsonElement(type = JsonElementType.JSON_KEY)
public static final String KEY_FIRST_NAME = "FirstName";
@JsonElement(type = JsonElementType.JSON_KEY)
public static final String KEY_PASSWORD = "Password";
@JsonElement(type = JsonElementType.JSON_KEY)
public static final String KEY_EMAIL = "EmailAddress";
@JsonElement(type = JsonElementType.JSON_KEY)
public static final String KEY_USERNAME = "Username";
@JsonElement(type = JsonElementType.JSON_KEY)
public static final String KEY_USER_ID = "UserId";
@JsonElement(type = JsonElementType.JSON_KEY)
public static final int USERNAME_LENGTH = 5;
@Id
@Column(name = "USER_ID")
@NotNull
private String id;
@Column(name = "USERNAME", nullable = false, unique = true)
@NotNull
private String username;
@Column(name = "EMAIL_ADDRESS", nullable = false, unique = true)
@NotNull
private String emailAddress;
@Column(name = "PASSWORD")
@NotNull
@Size(min = 5, max = 25)
private String password;
@Column(name = "FIRST_NAME")
private String firstName;
@Column(name = "SURNAME")
private String surname;
@Column(name = "COUNTRY")
private String country;
@Column(name = "BIO")
private String bio;
@Column(name = "SESSION_ID")
private String sessionId;
@Column(name = "LAST_REST_CALL_MADE")
private Date lastRestCallMade;
@Column(name = "STATUS")
@NotNull
private int status;
@OneToOne
@JoinColumn(name = "imageId")
private ProfileImage profileImage;
public User() {
id = UUID.randomUUID().toString();
}
@JsonElement(type = JsonElementType.GETTER)
public ProfileImage getProfileImage() {
return profileImage;
}
@JsonElement(type = JsonElementType.SETTER)
public void setProfileImage(ProfileImage profileImage) {
this.profileImage = profileImage;
}
@JsonElement(type = JsonElementType.GETTER)
public String getId() {
return id;
}
@JsonElement(type = JsonElementType.SETTER)
public void setId(String id) {
this.id = id;
}
@JsonElement(type = JsonElementType.GETTER)
public String getUsername() {
return username;
}
@JsonElement(type = JsonElementType.SETTER)
public void setUsername(String username) {
this.username = username;
}
@JsonElement(type = JsonElementType.GETTER)
public String getEmailAddress() {
return emailAddress;
}
@JsonElement(type = JsonElementType.SETTER)
public void setEmailAddress(String emailAddress) {
this.emailAddress = emailAddress;
}
@JsonElement(type = JsonElementType.GETTER)
public String getPassword() {
return password;
}
@JsonElement(type = JsonElementType.SETTER)
public void setPassword(String password) {
this.password = password;
}
@JsonElement(type = JsonElementType.GETTER)
public String getFirstName() {
return firstName;
}
@JsonElement(type = JsonElementType.SETTER)
public void setFirstName(String firstName) {
this.firstName = firstName;
}
@JsonElement(type = JsonElementType.GETTER)
public String getSurname() {
return surname;
}
@JsonElement(type = JsonElementType.SETTER)
public void setSurname(String surname) {
this.surname = surname;
}
@JsonElement(type = JsonElementType.GETTER)
public String getBio() {
return bio;
}
@JsonElement(type = JsonElementType.SETTER)
public void setBio(String bio) {
this.bio = bio;
}
@JsonElement(type = JsonElementType.GETTER)
public String getCountry() {
return country;
}
@JsonElement(type = JsonElementType.SETTER)
public void setCountry(String country) {
this.country = country;
}
/**
* @return the sessionId
*/
public String getSessionId() {
return sessionId;
}
/**
* @param sessionId the sessionId to set
*/
@JsonElement(type = JsonElementType.SETTER)
public void setSessionId(String sessionId) {
this.sessionId = sessionId;
}
/**
* @return the lastRestCallMade
*/
public Date getLastRestCallMade() {
return lastRestCallMade;
}
/**
* @param lastRestCallMade the lastRestCallMade to set
*/
public void setLastRestCallMade(Date lastRestCallMade) {
this.lastRestCallMade = lastRestCallMade;
}
/**
* @return the status
*/
public int getStatus() {
return status;
}
/**
* @param status the status to set
*/
public void setStatus(int status) {
this.status = status;
}
}
これが私のuserDaoの機能です
@Override
public void addNewUser(User user) throws InvalidDataException {
// TODO: Add Transaction manager object here either using annototation
// or creating it programatically
if (mSessionFactory != null) {
session = mSessionFactory.getCurrentSession();
session.beginTransaction();
if (user.getUsername() == null
|| user.getUsername().length() < User.USERNAME_LENGTH) {
throw new InvalidDataException(
InvalidDataException.ERROR_USERNAME_NULL);
}
session.save(user);
}else{
throw new RuntimeException("mSession is null");
}
}
ここでは非常に簡単です。

session.save(user); を呼び出すとクラッシュします。
