org.springframework.beans.factory.UnsatisfiedDependencyException：錯誤創建豆

答： 原來這是與Hibernate 5.2.0的錯誤。我在我的Maven倉庫中切換到5.1.0，它工作得很好。org.springframework.beans.factory.UnsatisfiedDependencyException：錯誤創建豆

所以我一直在用Hibernate進行測試，並決定添加Spring。加入Spring後，我花了大約2-3個小時處理了多個不同的錯誤，但是這個問題讓我陷入了困境。我在這裏搜索，因爲這有很多問題，但他們都有不同的答案，可悲的是不工作。

Exception in thread "main" org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'regularUserDaoImpl': Unsatisfied dependency expressed through method 'setSessionFactory' parameter 0: Error creating bean with name 'sessionFactory' defined in class path resource [Spring-Configuration.xml]: Invocation of init method failed; nested exception is org.hibernate.tool.schema.spi.SchemaManagementException: Attempt to resolve foreign key metadata from JDBC metadata failed to find column mappings for foreign key named [FK220mhr6bs12en0vy6s1gjy0lb]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [Spring-Configuration.xml]: Invocation of init method failed; nested exception is org.hibernate.tool.schema.spi.SchemaManagementException: Attempt to resolve foreign key metadata from JDBC metadata failed to find column mappings for foreign key named [FK220mhr6bs12en0vy6s1gjy0lb]

這裏是我的春天-config.xml中：

這裏的DAO：

@Repository("regularUserDaoImpl") 
public class RegularUserDaoImpl implements RegularUserDao { 

    private SessionFactory sessionFactory; 

    @Autowired 
    public void setSessionFactory(SessionFactory sessionFactory) { 
     this.sessionFactory = sessionFactory; 
    } 
...

最後，這裏的主：

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); 
    } 
}

檢查這個外鍵是否存在於db'FK220mhr6bs12en0vy6s1gjy0lb' ..也是它指向的字段... –

@ redflar3我找到了相應的外鍵，但我不確定它爲什麼會引發錯誤？它的定義與所有其他外鍵相同。有關如何解決它的任何建議？不太清楚我可以如何解決這個問題，因爲其他外鍵正常工作。 –

您尚未發佈使用外鍵的實體，所以最好是手動重新創建FK或刪除數據庫並從實體模型中重新創建它。 –

原來這是一個與Hibernate 5.2.0的錯誤。我在我的Maven倉庫中切換到5.1.0，它工作得很好。
