使用Spring 3，maven，JPA，c3p0在hibernate中“java.lang.NoSuchFieldError：NONE”

问题：

Hibernate没有正确执行查询。 它出现了与slf4j相关的问题，但使用任何推荐的修复程序似乎都不起作用。

我已经为createQuery调用尝试了各种变量名组合，希望到目前为止我还没做好运，但是没有运气。 这个问题真让我难过，有没有人遇到过类似的东西？

堆栈跟踪：

PostgreSql数据库：

 diarmaid=# \d Event; Table "public.event" Column | Type | Modifiers ---------------+------------------------+--------------------------------------------------------- eventid | integer | not null default nextval('event_eventid_seq'::regclass) eventname | character varying(255) | eventdate | character varying(255) | eventcapacity | bigint | Indexes: "event_pkey" PRIMARY KEY, btree (eventid) 

UserInterface类：

 public class UserInterface { /** * @param args */ public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationcontext.xml"); EventDao eventDao = applicationContext.getBean("eventDao", EventDao.class); // Are there any events? System.out.println("Events: " + eventDao.numberOfEvents()); // Get all events List listEvents = eventDao.getAllEvents(); // & Print them all out. for(Event event : listEvents) { System.out.println(event); } System.out.println(eventDao.getEvent(2)); } } 

PostgresEventDao课程：

 public class PostgresEventDao extends JpaDaoSupport implements EventDao { @Override public String numberOfEvents() { return (String) getJpaTemplate() .getEntityManagerFactory() .createEntityManager() .createQuery("select count(ev.id) from Event ev") .getSingleResult(); } @Override public List getAllEvents() { return getJpaTemplate().find("from Event"); } @Override public Event getEvent(long id) { return (Event) getJpaTemplate() .getEntityManagerFactory() .createEntityManager() .createQuery("select d from Event d where d.id = " + id) .getSingleResult(); } @Override @Transactional public void setAllEvents(List listEvent) { for(Event event : listEvent) { getJpaTemplate().persist(event); } } } 

persistence.xml中：

    com.package.mvcfromscratch.entities.Event                

最后，applicationcontext.xml：

Answer 1

你包含了旧版本的hibernate-commons-annotations ，其中包含了JPA 1.0，它与Hibernate 3.5所需的JPA 2.0冲突。

此外，从Hibernate 3.5开始，您不再需要包含多个Hibernate工件。 你只需要在pom.xml声明hibernate-entitymanager ，它应该足够你的设置。

Answer 2

它在org.hibernate.ejb.QueryImpl抱怨这个代码行：

 private javax.persistence.LockModeType jpaLockMode = javax.persistence.LockModeType.NONE; 

由于javax.persistence.LockModeType.NONE在JPA2中是新的，我怀疑你的类路径上也有JPA1。 查找并删除它。
