java - Hibernate 配置，上下文初始化期间遇到异常，HomeController 和 sessionFactory 出错

Question

首先，我最近想在JAVA EE上提高自己。而且还有一个题目，居然和我的问题一样。但是解决方案对我不起作用。这是该主题的链接:

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory

另外一个话题是: java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration

无论如何，我会提供我面临的错误，

错误信息:

Org.springframework.beans.factory.UnsatisfiedDependencyException: Error >creating bean with name 'homeController': Unsatisfied dependency expressed >through field 'productDao;

nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Failed to introspect bean class

这是HomeController:

package com.emusicstore.controller;

import com.emusicstore.dao.ProductDao;
import com.emusicstore.model.Product;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import java.io.IOException;
import java.util.List;

@Controller
public class HomeController {

    @Autowired
    private ProductDao productDao;

    @RequestMapping("/")
    public String home(){
        return "home";
    }

    @RequestMapping("/productList")
    public String getProducts(Model model) {
        List<Product> products = productDao.getAllProducts();
        model.addAttribute("products", products);

        return "productList";
    }

    @RequestMapping("/productList/viewProduct/{productId}")
    public String viewProduct(@PathVariable String productId, Model model) throws IOException {
        Product product = productDao.getProductById(productId);
        model.addAttribute(product);
        return "viewProduct";
    }
}

ApplicationContext.xml:

</bean>

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

我尝试过的事情:

• 在 applicationContext.xml 中注册 bean 对象

bean id="productDao" class="com.emusicstore.dao.impl.ProductDaoImpl" />

• 用@Component注解ProductDao类

• 将 Hibernate 核心 jar 文件添加到项目结构

这也是我的项目结构的图片: Project Structure

尝试添加

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-tools</artifactId>
    <version>4.0.1.Final</version>
</dependency>

给你pom.xml文件
