java - Spring hibernate : No matching bean of type org. hibernate.SessionFactory

Question

我在 spring mvc 应用程序中遇到以下错误，我在 stackoverflow 上查找了相同的错误代码，但没有一个解决方案有效，因此再次将其发布在这里。我认为这是一些/一些 jar 未加载的问题，但我不确定。

我已经绞尽脑汁，但没有运气..希望其他人能指出我哪里出错了。

我收到错误

我还在 springmvc-servlet.xml 中定义了 session 工厂

我在employeedao中使用带有自动连接注释的sessionFactory

package com.java.bricks.dao.impl;

import java.util.List;

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

import com.java.bricks.dao.EmployeeDao;
import com.java.bricks.entity.EmployeeEntity;

@Repository("employeedao")
public class EmployeeDaoImpl implements EmployeeDao {

    @Autowired
    private SessionFactory sessionFactory;

    public void addEmployee(EmployeeEntity employee) {
         sessionFactory.getCurrentSession().saveOrUpdate(employee);

    }

    @SuppressWarnings("unchecked")
    public List<EmployeeEntity> listAllEmployees() {
        return sessionFactory.getCurrentSession().createCriteria(EmployeeEntity.class).list();
    }

    public void updateEmployee(EmployeeEntity employee) {
         sessionFactory.getCurrentSession().update(employee);
    }

    public EmployeeEntity getEmployeeEntity(Integer id) {
         return (EmployeeEntity)sessionFactory.getCurrentSession().get(EmployeeEntity.class,id);

    }

    public void deleteEmployee(Integer id) {
        sessionFactory.getCurrentSession().createQuery("DELETE FROM EmployeeEntity where EMPID = "+id).executeUpdate();
    }

}

更新1:

添加employeeEntity.java

package com.java.bricks.entity;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="Employee")
public class EmployeeEntity implements Serializable{

    /**
     * 
     */
    private static final long serialVersionUID = -7086842712981602982L;


    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="EMPID")
    private Integer id;

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

    @Column(name="EMPAGE")
     private Integer age;

    @Column(name="SALARY")
     private Long salary;

    @Column(name="ADDRESS")
     private String address;

    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Long getSalary() {
        return salary;
    }

    public void setSalary(Long salary) {
        this.salary = salary;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public static long getSerialversionuid() {
        return serialVersionUID;
    }





}

您必须将 sessionFactory bean 的类名更改为

org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean

在 spring 配置文件中
