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

问题：“java.lang.NoSuchFieldError的：NONE” 在Hibernate和Spring 3，行家，JPA，C3P0

休眠未正确执行查询。它看起来与slf4j有关的问题出错，但使用任何推荐的修复程序似乎都不起作用。

我已经尝试了createQuery调用的变量名称的各种组合，希望我做错了（TM）但目前还没有运气。这个问题真的让我难堪，有没有人遇到过类似的东西？

的UserInterface类：

public class UserInterface { 

    /**

    public static void main(String[] args) { 
     ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationcontext.xml");

}

PostgresEventDao类：

public class PostgresEventDao extends JpaDaoSupport implements EventDao { 

    @Override 
    public String numberOfEvents() { 
     return (String) getJpaTemplate() 
      .getEntityManagerFactory() 
      .createEntityManager()

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

    } 

}

的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?>

另外，我在eclipse中以Run-> As Java Application的形式运行它。 – Diarmaid 2011-04-20 08:39:49

你包括老版hibernate-commons-annotations，其中包括及物动词JPA 1.0 ，这与Hibernate 3.5所需的JPA 2.0冲突。另外，由于Hibernate 3.5不再需要包含多个Hibernate构件，因此，您只需在pom.xml中声明hibernate-entitymanager，对于您的设置就足够了。

谢谢 - 马上解决它。我删除了Hibernate的所有依赖关系，并将它运行。现在不同的错误信息，但完全不相关 - 只是我的错误编码;） – Diarmaid 2011-04-20 08:45:30

它抱怨这行代码中org.hibernate.ejb.QueryImpl：

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

由于javax.persistence.LockModeType.NONE是JPA2新的，我怀疑你也有JPA1在你的类路径的某处。找到并移除它。

正如axtavt建议的，我包括一个旧版本的hibernate-commons-annotations。这确实包括JPA1，这是我的问题。感谢您的输入=） – Diarmaid 2011-04-20 08:47:27
