我需要有关此错误的帮助:java.lang.NoSuchMethodError

Question

我有这个Java代码(JPA):

String queryString = "SELECT b  , sum(v.votedPoints) as votedPoint " +
                       " FROM Bookmarks b  " +
                         " LEFT OUTER JOIN Votes v " +
                           " on (v.organizationId = b.organizationId) " + 
                         "WHERE b.userId = 101  " + 
                         "GROUP BY b.organizationId " +
                         "ORDER BY votedPoint ascending ";
EntityManager em = getEntityManager();
Query query = em.createQuery(queryString);
query.setFirstResult(start);
query.setMaxResults(numRecords);
List results = query.getResultList();

我不知道我的查询有什么问题,因为它给了我这个错误:

java.lang.NoSuchMethodError: org.hibernate.hql.antlr.HqlBaseParser.recover(Lantlr/RecognitionException;Lantlr/collections/impl/BitSet;)V

谢谢.

您使用的hibernate和ANTLR jar版本肯定存在问题.在版本2.7.6之前,ANTLR Parser类中没有恢复方法？如果您使用的是早期版本的ANTLR,例如2.7.2,那么您将看到此问题.

使用maven会导致这种情况,你依赖于Hibernate及其传递依赖,但是"更接近"; 例如Struts; 提供者ANTLR的早期版本不同,早期版本在您的应用程序中得到解决.

如果您能提供所涉及的罐子的版本,我们将能够提供更多帮助.一旦你修复了jar版本的问题,你应该得到一个更具启发性的错误信息,它显示你的HQL表达式有什么问题.
