版本信息：hibernate-release-5.1.0.Final
使用数据库：mysql
工程介绍：打印数据库信息到控制栏

1. 新建java项目名：hibernateDemo001，建立下图结构，将Hibernate中java8和required文件夹下的包导入项目
   

Student.java的代码为：

package com.feng.dao;

public class Student {

    @Override
    public String toString() {
        // TODO Auto-generated method stub
        return "\r id:"+id+"\r name:"+name+"\r sex:"+sex+"\r birthday:"+birthday+"\r state:"+state;
    }
    private Integer id; //id
    private String name; //name
    private String sex; //sex
    private String birthday; //birthday
    private Integer state;//state
//  private Integer a;

    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 String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    public String getBirthday() {
        return birthday;
    }
    public void setBirthday(String birthday) {
        this.birthday = birthday;
    }
    public Integer getState() {
        return state;
    }
    public void setState(Integer state) {
        this.state = state;
    }
}

student.hbm.xml代码为：
