Hibernate学习笔记

1、The Session internals consist of a queue of SQL statements that need to be synchronized with the database at some point and a map of managed persistenceinstances that are monitored by the Session.)

2、JPA, JTA

3、开源工具:OpenJPA, HSQLDB, Zmanda

4、Hibernate配置文件

命名规则:Classname.hbm.xml,一般放在和Class一个文件夹下

文件格式:

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC"-//Hibernate/Hibernate Mapping DTD//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>

......

</hibernate-mapping>

5、Hibernate的主键生成策略

  • incresement

举例:

<class name="hello.Message" table="MESSAGES">
  <id name="id" column="MESSAGE_ID">
    <generator class="increment" />
  </id>
</class>

To be continued...
