[英]org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean
ANSWER: Turns out it's a bug with Hibernate 5.2.0. 答案: 原来这是Hibernate 5.2.0的一个错误。 I switched to 5.1.0 in my Maven repository and it works perfectly fine.
我在我的Maven存储库中切换到5.1.0,它工作得很好。
So I've been testing things out with Hibernate and decided to add Spring. 所以我一直在用Hibernate进行测试,并决定添加Spring。 Upon adding Spring, I've spent around 2-3 hours going through multiple different errors, but this one has me stuck.
加入Spring之后,我花了大约2-3个小时来经历多个不同的错误,但这使我陷于困境。 I've searched on here as there's multiple questions about this, but they all have different answers that sadly don't work.
我在这里进行搜索,因为对此有多个问题,但是它们都有不同的答案,可惜无法解决。

Here's my spring-config.xml: 这是我的spring-config.xml:

Here's the DAO: 这是DAO:
@Repository("regularUserDaoImpl")
public class RegularUserDaoImpl implements RegularUserDao {
private SessionFactory sessionFactory;
@Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
...
And finally, here's main: 最后,这是主要的:
public class App
{
public static void main( String[] args )
{
ApplicationContext context = new ClassPathXmlApplicationContext("Spring-Configuration.xml");
RegularUserServiceImpl regularUserService = (RegularUserServiceImpl) context.getBean("regularUserServiceImpl");
RegularUser regularUser = new RegularUser();
regularUser.setFirstName("John");
regularUserService.save(regularUser);
}
}
Turns out it's a bug with Hibernate 5.2.0. 原来这是Hibernate 5.2.0的一个错误。 I switched to 5.1.0 in my Maven repository and it works perfectly fine.
