我一直在关注本教程： http://www.scribd.com/doc/25244173/Java-Struts-Spring-Hibernate-Tutorial 设置（前面描述）与教程文件工作正常，但是当我更改 - 删除/更新操作不会发生。没有错误或怪癖，它完全忽略了我！至于检索数据 - 一切都很完美..休眠和弹簧加载操作做trich，更新/删除操作不要
几乎所有来自tut的文件都是相同的，有这些差异;本教程使用一个服务文件：
Services.java
package services;
import org.springframework.transaction.annotation.Transactional;
import org.hibernate.SessionFactory;
import org.hibernate.Session;
import data.*;
import java.util.List;
// This class is the business services tier in the application.
// @Transactional is needed so that a Hibernate transaction is set up,
// otherwise updates won't have an affect
@Transactional
public class Services {
// So Spring can inject the session factory
SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory value) {
sessionFactory = value;
}
// Shortcut for sessionFactory.getCurrentSession()
public Session sess() {
return sessionFactory.getCurrentSession();
}
public Event getEventById(long id) {
return (Event) sess().load(Event.class, id);
}
public Person getPersonById(long id) {
return (Person) sess().load(Person.class, id);
}
public void deleteEventById(long id) {
sess().delete(getEventById(id));
}
public void deletePersonById(long id) {
sess().delete(getPersonById(id));
}
public void createEvent(String name) {
Event theEvent = new Event();
theEvent.setName(name);
sess().save(theEvent);
}
public void createPerson(String name) {
Person p = new Person();
p.setName(name);
sess().save(p);
}
@SuppressWarnings("unchecked")
public List getEvents() {
return sess().createQuery("from Event").list();
}
@SuppressWarnings("unchecked")
public List getPeople() {
return sess().createQuery("from Person").list();
}
public void removePersonFromEvent(int personId, int eventId) {
getEventById(eventId).getPeople().remove(getPersonById(personId));
}
public void addPersonToEvent(int personId, int eventId) {
getEventById(eventId).getPeople().add(getPersonById(personId));
}
}
，我曾尝试使用父控制器和静态调用的HibernateUtil的文件分开： HibernateUtil.java
package com.epa.util;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Transactional;
@Transactional
public class HibernateUtil {
// So Spring can inject the session factory
static SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory value) {
sessionFactory = value;
}
// Shortcut for sessionFactory.getCurrentSession()
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
BaseController.java
package com.epa.controller.base;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Transactional;
import com.epa.controller.EventController;
import com.epa.controller.PersonController;
import com.epa.util.HibernateUtil;
@Transactional
public class BaseController {
protected SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
// Shortcut for sessionFactory.getCurrentSession()
public Session sess() {
return sessionFactory.getCurrentSession();
}
private PersonController personController = null;
private EventController eventController = null;
public PersonController getPersonController() {
if (this.personController == null) {
this.personController = new PersonController();
}
return personController;
}
public EventController getEventController() {
if (this.eventController == null) {
this.eventController = new EventController();
}
return eventController;
}
}
EventController.java
package com.epa.controller;
import java.util.List;
import org.springframework.transaction.annotation.Transactional;
import com.epa.controller.base.BaseController;
import com.epa.model.Event;
@Transactional
public class EventController extends BaseController {
public Event getEventById(long id) {
return (Event) sess().load(Event.class, id);
}
public void deleteEventById(long id) {
sess().delete(getEventById(id));
}
public void createEvent(String name) {
Event theEvent = new Event();
theEvent.setName(name);
sess().save(theEvent);
}
@SuppressWarnings("unchecked")
public List getEvents() {
return sess().createQuery("from Event").list();
}
}
