控制器：

@Controller
@RequestMapping("/general")
public class OrderController {
    private OrderService orderService;

    @Autowired
    @Qualifier("orderServiceImpl")
    public void setOrderService(OrderService orderService) {
        this.orderService = orderService;

        orders = orderService.uploadOrders(orders, file);
        orderService.save(orders);

        return "redirect:/general/list";
    }
}

模型：

@Entity
@Table(name = "orders")
public class Orders {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private int id;

    @Column(name = "description")
    private String description;

    @Column(name = "price")
    private int price;

    @Column(name = "sold")
    private boolean sold;

    @Column(name = "body")
    private String body;

    @Column(name = "brand")
    private String brand;

    @Column(name = "engine")
    private String engine;

    @Column(name = "model")
    private String model;

    @Lob
    @Column(name = "image")
    private byte[] image;

    @Column(name = "imageStr")
    private String imageStr;


    public Orders() {
    }

    public Orders(int id) {
        this.id = id;
    }

    public int getId() {
        return id;

    public void setId(int id) {
        this.id = id;

    public String getBody() {
        return body;

    public void setBody(String body) {
        this.body = body;

    }

    public void setImageStr(String imageStr) {
        this.imageStr = imageStr;
    }
}

存储库：

@Repository
public interface Dao extends CrudRepository<Orders, Long>{

}

订购服务：

public interface OrderService {
    List<Orders> getOrders();

    Orders uploadOrders(Orders orders, MultipartFile file) throws IOException;

    void save(Orders orders);
}

订单服务实现：

@Service
public class OrderServiceImpl implements OrderService {

    private Dao dao;


    @Autowired
    public OrderServiceImpl(Dao dao) {
        this.dao = dao;
    }

    @Override
    public List<Orders> getOrders() {
        return Lists.newArrayList(dao.findAll());
    }

    @Override
    public void save(Orders orders) {
        dao.save(orders);
    }

    @Override
    public Orders uploadOrders(Orders orders, MultipartFile file) throws IOException {
        if (!file.isEmpty()) {
            String uploadDir = file.getOriginalFilename();

            orders.setImage(file.getBytes());
            orders.setImageStr(uploadDir);
        }

        return orders;
    }
}

我在 hibernate.cfg.xml 中添加了这样的代码：

  <bean id="myDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.postgresql.Driver"/>
        <property name="url"/>
        <property name="username" value="postgres"/>
        <property name="password" value="root"/>
    </bean>

    <bean id="entityManagerFactory"
          class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="packagesToScan" value="models" />
        <property name="dataSource" ref="myDataSource" />

        <property name="jpaProperties">
            <props>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            </props>
        </property>

        <property name="persistenceProvider">
            <bean class="org.hibernate.jpa.HibernatePersistenceProvider"></bean>
        </property>

    </bean>

    <bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>

    <jpa:repositories base-package="repository" entity-manager-factory-ref="entityManagerFactory" />

我还在 OrderServiceImpl 类中添加了这个：

@Resource
private Dao dao;

现在没有错误，一切正常
