通过字段“产品道”表达的不满意依赖性

时间:2017-10-14 17:42:58

标签: java spring h2

我看到几个主题有同样的问题,但似乎原因不同。在我的情况下,在我将所有内容从虚拟数据更改为H2数据库后,尝试在调试模式下启动应用程序时出现错误。我认为我定义了所有内容,但显然有一些错误,但我无法找到它!

请帮帮我:(

我的错误日志是:

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

import java.io.IOException;

@Controller
public class HomeController {

    @Autowired
    private ProductDao productDao;

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

最后我的ProductDaoImpl.java是:

    public void addProduct(Product product) {
        Session session = sessionFactory.getCurrentSession();
        session.saveOrUpdate(product);
        session.flush();
    }

    public Product getProductById(String id) {
        Session session = sessionFactory.getCurrentSession();
        Product product = (Product) session.get(Product.class, id);
        session.flush();
        return product;
    }

    public List<Product> getAllProduct() {
        Session session = sessionFactory.getCurrentSession();
        List<Product> products = (List<Product>) session.createCriteria("from Product").list();
        session.flush();
        return products;
    }

    public void deleteProduct(String id) {
        Session session = sessionFactory.getCurrentSession();
        session.delete(getProductById(id));
        session.flush();
    }
}

答案 0 :(得分:0)

您是如何构建和启动应用程序的?

在任何情况下,服务器都无法使用hibernate库。我假设您正在出口作为战争并在某些服务器上部署,并且您缺少某个包含此jar的地方。

将jar导入WEB-INF / lib文件夹并尝试。

或点击此处https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#build-tool-plugins-maven-packaging 创建一个jar / war文件
