目标:将Student实体对象加入数据库
1、首先需要下载三个东西:hibernate,slf4j,mysql。
2、分别取他们的包导入新建的项目中,我这里的版本是:hibernate-release-5.2.10里面lib目录下的required中的全部文件 slf4j-1.7.25下的受slf4j-nop-1.7.25.jar mysql的mysql-connector-java-5.1.42-bin.jar
3、在src下配置hibernate.cfg.xml(建议直接去文档复制然后改)

4、在mysql中创建student表,字段:id age name
5、创建自己的实体类在src下建包student,然后建Class:Student.java

package student;
public class Student {
private int id;
private int age;
private String name;
public int getId() {
return id;
}
public void setId( int id) {
this .id = id;
}
public int getAge() {
return age;
}
public void setAge( int age) {
this .age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this .name = name;
}
public Student( int id, int age, String name) {
super ();
this .id = id;
this .age = age;
this .name = name;
}
public Student() {
// TODO Auto-generated constructor stub
}
}

6、在对应package即student下配置文件:Student.hbm.xml

</ id >
< property name = "name" type = "string" column = "name" />
< property name = "age" type = "int" column = "age" />
</ class >
</ hibernate-mapping >

7、创建测试类:StudentText.java

package student;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class StudentText {
public static void main(String[] args) {
Student stu = new Student();
stu.setId( 4 );
stu.setName( "小明" );
stu.setAge( 12 );
Configuration con = new Configuration();
SessionFactory sf = con.configure().buildSessionFactory();
Session s = sf.openSession();
s.beginTransaction();
s.save(stu);
s.getTransaction().commit();
s.close();
sf.close();
}
}

输出结果,完成:
