hibernate执行流程

"After you" is good manners. “您先请”是礼貌

hibernate底层实现很复杂，但是它的使用流程确实很明晰的，下面的代码和流程图是相互对应的，结合起来看，就可以看得很明白了

代码对应：

Java代码

1. package com.bjsxt.hibernate.model; 
2.  
3. import org.hibernate.Session; 
4. import org.hibernate.SessionFactory; 
5. import org.hibernate.cfg.Configuration; 
6.  
7. public class StudentTest { 
8.  
9.     /**
10.      * @param args
11.      */ 
12.     public staticvoid main(String[] args) { 
13.         // TODO Auto-generated method stub 
14.         Student stu = new Student(); 
15.         stu.setAge(2); 
16.         stu.setId(2); 
17.         stu.setName("mlc"); 
18.          
19.         Configuration cf = new  Configuration(); 
20.         SessionFactory sf = cf.configure().buildSessionFactory(); 
21.         Session session =sf.openSession(); 
22.         session.beginTransaction(); 
23.         session.save(stu); 
24.         session.getTransaction().commit(); 
25.         session.close(); 
26.         sf.close(); 
27.     } 
28. } 

package com.bjsxt.hibernate.model;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.Configuration;public class StudentTest {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubStudent stu = new Student();stu.setAge(2);stu.setId(2);stu.setName("mlc");Configuration cf = new  Configuration();SessionFactory sf = cf.configure().buildSessionFactory();Session session =sf.openSession();session.beginTransaction();session.save(stu);session.getTransaction().commit();session.close();sf.close();}}

下面的代码是前一篇hibernate的helloworld的一个测试代码片段，整个过程很清晰，就不多说了

如果有具体的问题，可以针对性的讨论
