Я новичок в спящий режим и все еще учусь, я получаю след стека ниже для следующего кода:Неправильное значение даты и времени Hibernate
package com.simpleprogrammer;
import org.hibernate.Session;
import java.util.Date;
public class Program {
public static void main(String[] args) {
System.out.println(org.hibernate.Version.getVersionString());
System.out.println("Creating session!");
Session session = HibernateUtilities.getSessionFactory().openSession();
session.beginTransaction();
User user = new User();
user.setName("Joe");
user.addHistory(new UserHistory(new Date(), "Set the name to Joe"));
System.out.println("Name set to Joe!!");
user.getProtienData().setGoal(250);
user.addHistory(new UserHistory(new Date(), "Set the goal to 250"));
System.out.println("Goal set to 250!!");
session.save(user);
System.out.println("Session saved");
session.getTransaction().commit();
System.out.println("Commit done - well done!!");
System.out.println("Beginning transaction!");
session.beginTransaction();
User loadedUser = (User) session.load(User.class, 1);
System.out.println("Name of user is " + loadedUser.getName());
System.out.println("Number of goal is " + loadedUser.getProtienData().getGoal());
for(UserHistory history : loadedUser.getHistory())
{
System.out.println(history.getEntryTime().toString() + " " + history.getEntry());
}
loadedUser.getProtienData().setTotal(loadedUser.getProtienData().getTotal() + 50);
loadedUser.addHistory(new UserHistory(new Date(), "Added 50 protein"));
System.out.println("Total of user is " + loadedUser.getProtienData().getTotal());
session.getTransaction().commit();
System.out.println("After commit, total of user is " + loadedUser.getProtienData().getTotal());
session.close();
HibernateUtilities.getSessionFactory().close();
}
}
Мой класс proteinData выглядит следующим образом:
package com.simpleprogrammer;
public class ProtienData {
private int total;
private int goal;
public int getGoal() {
return goal;
}
public void setGoal(int goal) {
this.goal = goal;
}
public int getTotal() {
return total;
}
public void setTotal(int total) {
this.total = total;
}
}
И мой файл User.java является: пакет со m.simpleprogrammer;
import javax.persistence.Entity;
import javax.persistence.Id;
import java.util.*;
@Entity
public class User {
@Id
private int id;
private String name;
private ProtienData protienData = new ProtienData();
private List<UserHistory> history = new ArrayList<UserHistory>();
public void addHistory(UserHistory historyItem) {
historyItem.setUser(this);
history.add(historyItem);
}
public ProtienData getProtienData() {
return protienData;
}
public List<UserHistory> getHistory() {
return history;
}
public void setHistory(List<UserHistory> history) {
this.history = history;
}
public void setProtienData(ProtienData protienData) {
this.protienData = protienData;
}
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;
}
}
Мой UserHistory класс выглядит следующим образом:
package com.simpleprogrammer;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import java.util.Date;
public class UserHistory {
private int id;
private User user;
private Date entryTime;
private String entry;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public UserHistory(Date entryTime, String entry) {
this.entry = entry;
this.entryTime = entryTime;
}
public UserHistory() {
}
public Date getEntryTime() {
return entryTime;
}
public void setEntryTime(Date entryTime) {
this.entryTime = entryTime;
}
public String getEntry() {
return entry;
}
public void setEntry(String entry) {
this.entry = entry;
}
}
Один из моих отображения файла гибернации выглядит следующим образом: (с заголовком и т.д. удалены)
<class name="com.simpleprogrammer.UserHistory" table = "USERHISTORY">
<id name="id" type="int">
<column name="ID" />
<generator class="increment"/>
</id>
<many-to-one name="user" class="com.simpleprogrammer.User" not-null="true">
<column name="USER_ID" />
</many-to-one>
<property name="entryTime" type="java.util.Date">
<column name="ENTRYTIME" />
</property>
<property name="entry" type="java.lang.String">
<column name="ENTRY" />
</property>
</class>
а другой - следующим образом:
<component name = "protienData">
<property name="total" type="int">
<column name="TOTAL" />
</property>
<property name="goal" type="int">
<column name="GOAL" />
</property>
</component>
<list name = "history" table="USER_HISTORY" inverse="true" cascade="save-update">
<key column="USER_ID"/>
<list-index column="POSITION"/>
<one-to-many class="com.simpleprogrammer.UserHistory"/>
</list>
</class>
</hibernate-mapping>
Я получаю следующее сообщение об ошибке при попытке запустить это:

Кто-нибудь знает, что является причиной этого>
Можете ли вы добавить исходный код для класса UserHistory. – emeraldjava
Класс UserHistory теперь добавлен Paul :) – user3600952
