开发过程：
1.建立三个表tb_topic,tb_reply,tb_manager

CREATE TABLE `tb_topic` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `author` varchar(20) DEFAULT NULL,
  `face` varchar(10) DEFAULT NULL,
  `content` text,
  `ip` varchar(16) DEFAULT NULL,
  `email` varchar(100) DEFAULT NULL,
  `createTime` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

CREATE TABLE `tb_reply` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `topcid` int(10) DEFAULT NULL,
  `author` varchar(20) DEFAULT NULL,
  `content` text,
  `createTime` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

CREATE TABLE `tb_manager` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(30) DEFAULT NULL,
  `pwd` varchar(30) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

2.建立hibernate配置文件

xml version='1.0' encoding='UTF-8'?>
DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory>
    <property name="connection.username">rootproperty>
    <property name="connection.url">
        jdbc:mysql://localhost:3306/test
    property>
    <property name="dialect">
        org.hibernate.dialect.MySQLDialect
    property>
    <property name="myeclipse.connection.profile">mysqlproperty>
    <property name="connection.driver_class">
        com.mysql.jdbc.Driver
    property>
    <property name="show_sql">trueproperty>
    <property name="transaction.factory_class">
        org.hibernate.transaction.JDBCTransactionFactory
    property>

session-factory>

hibernate-configuration>

3.创建实体类及其映射文件

package com.actionForm;

public class TopicForm {

    private int id = -1;
    private String author = "";
    private String face = "";
    private String content = "";
    private String ip = "";
    private String email = "";
    private String createTime = "";

    //getXXX() and setXXX()

}

TopicForm.hbm.xml

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>
    <class name="com.actionForm.TopicForm" table="tb_topic">

        <id name="id" column="id" type="int">
            <generator class="increment" />
        id>
        <property name="author" column="author" type="string"
            not-null="true" />
        <property name="face" column="face" type="string"
            not-null="true" />
        <property name="content" column="content" type="string"
            not-null="true" />
        <property name="ip" column="ip" type="string" not-null="true" />
        <property name="email" column="email" type="string" />
        <property name="createTime" column="createTime" type="string"
            not-null="true" />

    class>
hibernate-mapping>

package com.actionForm;

public class ReplyForm {

    private int id = -1;
    private int topicid = -1;
    private String author = "";
    private String content = "";
    private String createTime = "";

    //getXXX() and setXXX()

}

ReplyForm.hbm.xml

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>
    <class name="com.actionForm.ReplyForm" table="tb_Reply">
        <id name="id" column="id" type="int">
            <generator class="increment" />
        id>
        <property name="topicid" column="topicid" type="int"
            not-null="true" />
        <property name="author" column="author" type="string" />
        <property name="content" column="content" type="string" />
        <property name="createTime" column="createTime" type="string" />
    class>
hibernate-mapping>
