「java.lang.NoSuchFieldError的：NONE」 在Hibernate和Spring 3，行家，JPA，C3P0

Question

問題：

休眠未正確執行查詢。它看起來與slf4j有關的問題出錯，但使用任何推薦的修復程序似乎都不起作用。

我已經嘗試了createQuery調用的變量名稱的各種組合，希望我做錯了（TM）但目前還沒有運氣。這個問題真的讓我難堪，有沒有人遇到過類似的東西？

PostgreSQL數據庫：

diarmaid=# \d Event; 
             Table "public.event" 
    Column  |   Type   |      Modifiers       
---------------+------------------------+--------------------------------------------------------- 
eventid  | integer    | not null default nextval('event_eventid_seq'::regclass)

eventdate  | character varying(255) | 
eventcapacity | bigint     | 
Indexes: 
    "event_pkey" PRIMARY KEY, btree (eventid) 

的UserInterface類：

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<Event> listEvents = eventDao.getAllEvents(); 
     // & Print them all out. 
     for(Event event : listEvents) { 
      System.out.println(event); 
     } 
     System.out.println(eventDao.getEvent(2)); 
    } 

} 

PostgresEventDao類：

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<Event> 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<Event> listEvent) { 
     for(Event event : listEvent) { 
      getJpaTemplate().persist(event); 
     } 

    } 

} 

的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="2.0" 
    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Answer 1

你包括老版hibernate-commons-annotations，其中包括及物動詞JPA 1.0 ，這與Hibernate 3.5所需的JPA 2.0衝突。另外，由於Hibernate 3.5不再需要包含多個Hibernate構件，因此，您只需在pom.xml中聲明hibernate-entitymanager，對於您的設置就足夠了。

參見：

Answer 2

它抱怨這行代碼中org.hibernate.ejb.QueryImpl：

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

由於javax.persistence.LockModeType.NONE是JPA2新的，我懷疑你也有JPA1在你的類路徑的某處。找到並移除它。
