创建名称为＆＃39; sessionFactory＆＃39;的bean时出错在ServletContext中定义

Question

我知道这是重复的，但我花了好几天时间处理所有解决方案。我还没有能够得到任何工作。有人可以看看。

如果需要任何其他信息，请告知我们。

我的Stacktrace如下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: Unable to load class [ com.davis.ty.domain.Products] declared in Hibernate configuration <mapping/> entry

    org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:195)

我的servlet.xml如下：

我的hibrenate.cfg.xml是这样的：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <mapping class="com.davis.ty.domain.Products" />
    </session-factory>
</hibernate-configuration>

我的sessionfactory代码是：

package com.davis.ty.dao;

import java.util.List;

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

import com.davis.ty.domain.Products;

@Repository
public class ProductsDAOImpl implements  ProductsDAO{

    @Autowired
    private SessionFactory sessionFactory;

    public void addProduct(Products products) {
        sessionFactory.getCurrentSession().save(products);
    }

    public void updateProduct(Products products)
     {
          sessionFactory.getCurrentSession().merge(products);
     }

    @SuppressWarnings("unchecked")
    public List<Products> listProducts() {

        return sessionFactory.getCurrentSession().createQuery("from Products").list();
    }

    public void removeProducts(int id) {
        Products products = (Products) sessionFactory.getCurrentSession().load(
                Products.class, id);
        if (null != products) {
            sessionFactory.getCurrentSession().delete(products);
        }

    }

    @Override
    public Products getProductsById(int id) {

         return (Products) sessionFactory.getCurrentSession().get(Products.class, id);

    }

}

我的表单类如下：

package com.davis.ty.domain;


    import javax.persistence.Column;
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.GenerationType;
    import javax.persistence.Id;
    import javax.persistence.Table;
    import java.math.BigDecimal;

    /**

    @Entity
    @Table(name="products")
    public class Products {

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

        @Column(name="CODE")
        private int code;

        @Column(name="Dept")
        private int dept;

        @Column(name="DESC")
        private String desc;

        @Column(name="Price")
        private BigDecimal price;

        @Column(name="Tax")
        private BigDecimal tax;

        @Column(name="Shipping")
        private BigDecimal ship;

        public int getId() {
            return id;
        }

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

        public int getCode() {
            return code;
        }

        public void setCode(int code) {
            this.code = code;
        }

        public int getDept() {
            return dept;
        }

        public void setDept(int dept) {
            this.dept = dept;
        }

        public String getDesc() {
            return desc;
        }

        public void setDesc(String desc) {
            this.desc = desc;
        }

        public BigDecimal getPrice() {
            return price;
        }

        public void setPrice(BigDecimal price) {
            this.price = price;
        }

        public BigDecimal getTax() {
            return tax;
        }

        public void setTax(BigDecimal tax) {
            this.tax = tax;
        }

        public BigDecimal getShip() {
            return ship;
        }

        public void setShip(BigDecimal ship) {
            this.ship = ship;
        }


    }
