本文环境：eclipse4.4.0+hibernate4.1+hibernate tools4.0.1+mysql5.7

**1 安装hibernate tools插件：**

help -> Eclipse Marketplace  
注：eclipse会搜索出适合该版本eclipse安装的hibernate tools，点击安装即可安装

**2 创建hibernate配置文件hibernate.cfg.xml及console配置文件**

2.1新建Java或者Java web项目，这里建立了一个Java web项目hibernate\_taotao，建立cn.com.pojo package存放pojo等

2.2选中项目，右键-> new -> other -> hibernate -> hibernate configuration file

2.3然后 next，配置console文件，创建了配置文件hibernate.cfg.xml  
![这里写图片描述][SouthEast 3]

<?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="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
            <property name="hibernate.connection.password">ccssxx</property>
            <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3306/taotao?characterEncoding=utf-8</property>
            <property name="hibernate.connection.username">root</property>
            <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
        </session-factory>
    </hibernate-configuration>

**3 创建hibernate.reveng.xml文件:**

3.1选中项目，右键 -> new -> other -> hibernate -> hibernate reverse engineering file

3.2下一步，配置要生成POJO对应的表

3.3finish生成hibernate.reveng.xml文件

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >
    
    <hibernate-reverse-engineering>
      <table-filter match-catalog="taotao" match-name="tb_content"/>
      <table-filter match-catalog="taotao" match-name="tb_content_category"/>
      <table-filter match-catalog="taotao" match-name="tb_item"/>
      <table-filter match-catalog="taotao" match-name="tb_item_cat"/>
      <table-filter match-catalog="taotao" match-name="tb_item_desc"/>
      <table-filter match-catalog="taotao" match-name="tb_item_param"/>
      <table-filter match-catalog="taotao" match-name="tb_item_param_item"/>
      <table-filter match-catalog="taotao" match-name="tb_order"/>
      <table-filter match-catalog="taotao" match-name="tb_order_item"/>
      <table-filter match-catalog="taotao" match-name="tb_order_shipping"/>
      <table-filter match-catalog="taotao" match-name="tb_user"/>
    </hibernate-reverse-engineering>

**4 反向工程创建pojo：**

4.1 在java模式下的hibernate code generation configuration菜单中配置

![这里写图片描述][SouthEast 8]

4.2点击run配置成功，生成pojo和对应的XX.hbm.xml文件

**5 一般自动生成的mapping文件（XX.hbm.xml）都需要修改后才能使用：**
