org.springframework.beans.factory.BeanCreationException：创建名为'playerDAOImpl'的bean时出错：注入自动连接的依赖项失败

标签： java spring hibernate spring-mvc

我知道有很多类似的问题，但是我尽我所能来解决它​​，在这里挣扎了好几个小时。 Project是Spring MVC + Hibernate。我正在尝试通过注释创建bean，但似乎@Autowired是麻烦的根源。

的src /主/ JAVA PlayerDAOImpl

（Orginally类没有@Component注释，当我试图修复它时添加了这个，没有帮助）：

package com.roommate.myapp;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;




@Component
@Repository
public class PlayerDAOImpl implements PlayerDAO{

    @Autowired 
    private SessionFactory session;

    @Override
    public void add(Player player) {
        session.getCurrentSession().save(player);
    }

    @Override
    public void edit(Player player) {
        session.getCurrentSession().update(player);
    }

    @Override
    public void delete(int playerId) {
        session.getCurrentSession().delete(getPlayer(playerId));
    }

    @Override
    public Player getPlayer(int playerId) {
        return (Player)session.getCurrentSession().get(Player.class, playerId);
    }

    @Override
    public List getAllPlayers() {
        return session.getCurrentSession().createQuery("from Player").list();
    }

}

src / main / java PlayerDAO 

package com.roommate.myapp;

import java.util.List;

import org.springframework.stereotype.Component;


@Component
public interface PlayerDAO {

    public void add(Player player);
    public void edit(Player player);
    public void delete(int studentId);
    public Player getPlayer(int playerId);
    public List getAllPlayers();
}

我很抱歉代码墙，但我没有看到原因。最后我提供了pom.xml。

我看到了一些bean定义，但没有看到你的SessionFactory bean。错误在于它无法找到SessionFactory。您是否在上下文中的任何位置定义了它？

你有任何看起来像这样的东西（Springs文档中的一个例子） http://docs.spring.io/spring/docs/current/spring-framework-reference/html/orm.html

和

http://docs.spring.io/spring-framework/docs/3.2.3.RELEASE/javadoc-api/org/springframework/orm/hibernate4/LocalSessionFactoryBean.html 

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="org.hsqldb.jdbcDriver"/>
    <property name="url" value="jdbc:hsqldb:hsql://localhost:9001"/>
    <property name="username" value="sa"/>
    <property name="password" value=""/>
</bean>
<bean id="mySessionFactory"class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
   <property name="dataSource" ref=“myDataSource" />
      <property name="packagesToScan" value=“com.roommate.myapp” />
</bean>

您尚未声明会话工厂，您需要在应用程序context.xml中执行此操作。请参阅此处的示例 - https://github.com/webcompere/SpringHelloWorld - 用于休眠配置。
