org.springframework.beans.factory.UnsatisfiedDependencyException：创建bean时出错

Question

答案： 原来这是Hibernate 5.2.0的一个错误。 我在我的Maven存储库中切换到5.1.0，它工作得很好。

所以我一直在用Hibernate进行测试，并决定添加Spring。 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。 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。

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]

这是我的spring-config.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="
      http://www.springframework.org/schema/beans 
      http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
      http://www.springframework.org/schema/context 
      http://www.springframework.org/schema/context/spring-context-4.1.xsd">

   <context:component-scan base-package="com.glimpsmedia.app" />
   <context:property-placeholder location="classpath:resources/database.properties" />
   <context:annotation-config/>

   <bean id="sessionFactory"
    class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
      <property name="dataSource" ref="dataSource" />
      <property name="packagesToScan" value="com.glimpsmedia.app.model" />
      <property name="hibernateProperties">
         <props>
            <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
         </props>
      </property>
   </bean>

   <bean id="dataSource"
    class="org.apache.tomcat.dbcp.dbcp.BasicDataSource">
      <property name="driverClassName" value="${jdbc.driverClassName}" />
      <property name="url" value="${jdbc.url}" />
      <property name="username" value="${jdbc.user}" />
      <property name="password" value="${jdbc.pass}" />
   </bean>

   <bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
      <property name="sessionFactory" ref="sessionFactory" />
   </bean>

   <bean id="persistenceExceptionTranslationPostProcessor"
    class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>

</beans>

这是DAO：

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

    private SessionFactory sessionFactory;

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

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);
    }
}

原来这是Hibernate 5.2.0的一个错误。 我在我的Maven存储库中切换到5.1.0，它工作得很好。
