我一直坚持尝试让Spring DBUnit测试来测试我的dao功能。然而,经过这么多尝试后,我仍然坚持这种奇怪的说法无法加载应用程序上下文:
public interface IMyDao
{
List<Person> findAll();
}
@Repository("MyDao")
public class MyDaoImpl implements IMyDao
{
@Autowired
private SessionFactory sessionFactory;
@Override
public List<Person> findAll()
{
Query query = sessionFactory.getCurrentSession().createQuery("from Person");
return (List<Person>) query.list();
}
}
<dataset>
<person id="25" name="Dane" phone="61458972564"/>
<person id="21" name="Sam" phone="61458972564"/>

然而,当我运行它时,我得到了这个奇怪的异常,说无法加载应用程序上下文。

答案 0 :(得分:3)
阅读这一行:
java.lang.IncompatibleClassChangeError: class org.springframework.core.type.classreading.ClassMetadataReadingVisitor has interface org.springframework.asm.ClassVisitor as super class
似乎spring core和spring asm之间的版本存在冲突。如果你正在使用maven运行依赖:树来验证使用的是什么罐子
