Question

我正在开发一个小型的Spring MVC / Hibernate项目，我保留在以下链接中，https://github.com/Chaklader/backend我在收到hibernate之后收到此错误信息，

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customerDAO': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory com.backend.dao.CustomerDAO.sessionFactory; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [com/backend/config/applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing table [hibernate_sequence]

控制器源文件即下面提供的HomeController.java，

 package com.backend.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeControllers {

    @RequestMapping("/")
    public String showHome(){

        return "home";
    }
}

我的项目结构可以在这里看到（或者，在github中），

我认为主要错误消息是Error creating bean with name 'customerDAO': Injection of autowired dependencies failed;。如何解决这个问题？

编辑：

当我在applicationContext.xml文件中添加以下代码部分时，程序会崩溃。如何在Spring bean配置文件中正确添加hibernate定义？

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="mysqlDataSource"/>
    <property name="packagesToScan" value="com.backend.model" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.jdbc.batch_size">20</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.connection.SetBigStringTryClob">true</prop>
            <prop key="hibernate.hbm2ddl.auto">validate</prop>
        </props>
    </property>
</bean>

如何正确使用Spring MVC的hibernate？
