JavaPersistenceWithHibernate第二版笔记Getting started with ORM-001用JPA和Hibernate实现HellowWorld(JTA、Bitronix)

一、结构

二、model层

1.

 1 package org.jpwh.model.helloworld;
 2
 3 import javax.persistence.Entity;
 4 import javax.persistence.GeneratedValue;
 5 import javax.persistence.GenerationType;
 6 import javax.persistence.Id;
 7
 8 /*
 9     Every persistent entity class must have at least the <code>@Entity</code> annotation.
10     Hibernate maps this class to a table called <code>MESSAGE</code>.
11  */
12 @Entity
13 public class Message {
14
15     /*
16         Every persistent entity class must have an identifier
17         attribute annotated with <code>@Id</code>. Hibernate maps
18         this attribute to a column named <code>ID</code>.
19      */
20     @Id
21     /*
22         Someone must generate identifier values; this annotation enables
23         automatic generation of IDs.
24      */
25     @GeneratedValue//(strategy=GenerationType.TABLE)
26     private Long id;
27
28     /*
29         You usually implement regular attributes of a persistent class with private
30         or protected fields, and public getter/setter method pairs. Hibernate maps
31         this attribute to a column called <code>TEXT</code>.
32      */
33     private String text;
34
35     public String getText() {
36         return text;
37     }
38
39     public void setText(String text) {
40         this.text = text;
41     }
42 }

三、配置文件

1.persistence.xml(这个文件似乎不起作用)

  1 <persistence

932                  While you experiment with the second-level cache, you usually
933                  want to see and examine what‘s happening behind the scenes. Hibernate
934                  has a statistics collector and an API to access these statistics. For
935                  performance reasons, it is disabled by default (and should be
936                  disabled in production).
937             -->
938             <property name="hibernate.generate_statistics"
939                       value="true"/>
940         </properties>
941     </persistence-unit>
942
943 </persistence>

For the “Hello World” application, you delegate database connection handling to a Java Transaction API ( JTA ) provider, the open source Bitronix project. Bitronix offers connection pooling with a managed java.sql.DataSource and the standard javax.transaction.UserTransaction API in any Java SE environment. Bitronix binds
these objects into JNDI , and Hibernate interfaces automatically with Bitronix through JNDI lookups.

# Bitronix has a built-in JNDI context, for binding and looking up datasources
