【中文标题】休眠 JPA 错误【英文标题】：Hibernate JPA Error 【发布时间】：2012-04-19 00:30:37 【问题描述】：我一直在尝试在 Spring 3.0 项目中使用 Hibernate+JPA 从数据库中获取数据。它给了我异常 java.lang.NoSuchFieldError: INSTANCE。在这里，我给出了完整的堆栈跟踪。

谁能帮助解决这个问题？此错误的原因可能是什么以及如何解决？
谢谢 卡皮尔

【问题讨论】：
信息不够，至少你应该提供com.mpm.login.service.UserAuthentication.authenticateUser()和com.mpm.login.controller.LoginController.authenticate()的代码。
嗨，Ken，请看下面的代码。 public boolean authenticateUser(String uname, String password) // TODO 自动生成的方法 stub System.out.println("Inside authenticateUser");布尔用户身份验证=假；列表 lst=null; EntityManagerFactory emf = Persistence.createEntityManagerFactory("DBConnection"); EntityManager em = emf.createEntityManager(); System.out.println("Before Try 块");
@RequestMapping(value = "login.action", method = RequestMethod.POST) public @ResponseBody HashMap authenticate(@RequestParam("username") String username, @RequestParam("password") String password , HttpServletRequest 请求) HashMap loginMap = new HashMap(); UserAuthentication userAuthentication = new UserAuthentication(); boolean isUserAuthenticated=userAuthentication.authenticateUser（用户名，密码）； System.out.println("auth is "+isUserAuthenticated);
请勿将代码放在评论中，请通过编辑您的帖子发布它们
Ken，我已经在上面发布了我的 pom.xml。我一直在寻找其他版本的hibernate jar文件，但找不到。
【参考方案1】：
检查您的“com.mpm.login.model.Login”文件是否有任何声明为INSTANCE 的变量，如果存在则无法将该变量映射到数据库列。
【讨论】：
在提到的类中没有任何变量声明为实例。 INSTANCE 变量在 BasicTypeRegistry.java 中，它是一个休眠库文件。那么还有其他线索吗？ 我正在为我的 Hibernate 和 OpenJPA 项目使用以下库文件 但是我没有使用 EJB。 dom4j-1.6.1.jar、hibernate-annotations-3.4.0.GA.jar、hibernate-commons-annotations-3.1.0.GA.jar、hibernate-entitymanager-3.4.0.GA.jar、hibernate3-3.3。 2.GA.jar、javassist-3.9.0.GA.jar、log4j-1.2.16.jar、mysql-connector-java-5.1.16.jar、openjpa-all-2.0.0-M3.jar、oscache- 2.4.1.jar, slf4j-api-1.5.2.jar, slf4j-log4j12-1.5.2.jar 当你使用 EJB3 你有ejb3-persistence.jar 文件吗？
我这里也没有使用 EJB。我没有 ejb3-persistence.jar 文件。我认为我们不需要这个文件，因为 entitymanager.jar 会处理这个。如果我错了，请纠正我。
检查this和this以上是关于休眠 JPA 错误的主要内容，如果未能解决你的问题，请参考以下文章
