hibernate最基本的數據庫連接，使用mysql。????見一個java工程，見一個包名為“book”，????在book的包下加一個java類Book.java，其代碼如下：????package?book;????public?class?Book?{????private?Integer?id;????private?String?name;????private?String?writer;????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?getWriter（）?{????return?writer;????}????public?void?setWriter（String?writer）?{????this.writer?=?writer;????}????}????然后在book包下建一個book.hbm.xml，其代碼如下：????<?xml?version="1.0"?>????<!DOCTYPE?hibernate-mapping?PUBLIC????"-//Hibernate/Hibernate?Mapping?DTD?3.0//EN"????"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">????<hibernate-mapping?package="book"????default-lazy="false">????<class?name="Book">????<id?name="id">????<generator?class="increment"/>????</id>????<property?name="name"?></property>????<property?name="writer"?></property>????</class>????</hibernate-mapping>????這個事與數據庫里面的字段名形成映射關系，自己在mysql建立book表時與之對應，id是自增長的，????然后在工程的根目錄下建一個hibernate.cfg.xml.其代碼如下：????<?xml?version='1.0'?encoding='UTF-8'?>????<!DOCTYPE?hibernate-configuration?PUBLIC????"-? www.fkJAVA.com e?Configuration?DTD?3.0//EN"????"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">????<hibernate-configuration>????<session-factory>????<property?name="connection.driver_class">com.mysql.jdbc.Driver</property>????<property?name="connection.url">jdbc:mysql://localhost/mydb</property>????<property?name="connection.username">root</property>????<property?name="connection.password">root</property>????<property?name="dialect">org.hibernate.dialect.MySQLDialect</property>????<property?name="show_sql">true</property>????<!--?<property?name="hbm2ddl.auto">${hibernate.hbm2ddl.auto}</property>-->????<!--?<property?name="current_session_context_class">thread</property>-->????<mapping?resource="book/Book.hbm.xml"?/>????</session-factory>????</hibernate-configuration>????這是連接mysql數據庫的，用戶名和密碼改為你mysql數據庫的????<property?name="show_sql">true</property>這是在后臺打印sql語句????<mapping?resource="book/Book.hbm.xml"?/>這是找到映射文件。????然后些個測試類：代碼如下：????package?test;????import?org.hibernate.Session;????import?org.hibernate.SessionFactory;????import?org.hibernate.Transaction;????import?org.hibernate.cfg.Configuration;????import?book.Book;????public?class?MainTest?{????/**????*?@param?args????*/????public?static?void?main（String[]?args）?{????try?{????Configuration?cfg=new?Configuration（）。configure（）；????SessionFactory?sf=cfg.buildSessionFactory（）；????Session?session?=?sf.openSession（）；????Transaction?ts=session.beginTransaction（）；????Book?b=new?Book（）；????b.setName（"hibernate"）；????b.setWriter（"div"）；????session.save（b）；????//?Book?b=（Book）?session.get（Book.class,1）；????//?if（b!=null）{????//?b.setName（"xujun"）；????//?System.out.println（"書名為："+b.getName（））；????//?System.out.println（"作者為："+b.getWriter（））；????//?session.delete（b）；????//?}????ts.commit（）；????session.close（）；????sf.close（）；????}?catch?（Exception?e）?{????e.printStackTrace（）；????}????}????}????mysql表的字段如下：??????把數據庫建好后就可以測試。對了，關鍵的還沒有說，還得把antlr.jar,cglib.jar,asm.jar,asm-attrs.jar,commons-colletions.jar,commons-logging.jar,ehcache.jar,????jta.jar,dom4.jar,log4.jar,hibernate3.jar引入到lib目錄下
