接上篇文章（點選開啟連結），給出Hibernate註解配置持久化類的步驟：

一、同樣配置Hibernate.cfg.xml:

<?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">

        <property name="hibernate.connection.password">1988419</property>  
        <!-- 配置方言為每一種資料庫提供特殊sql適配-->  
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>  

		<!-- c3p0連線池配置 -->

		<!-- 連線池最小連線 -->

        <!-- 連線池超時時長（毫秒） -->  
        <property name="hibernate.c3p0.timeout">5000</property>
        <!-- 指定連線池最大快取多少Statment物件 -->
        <property name="hibernate.c3p0.max_statment">50</property>
        <!-- 空閒檢測週期（毫秒） -->
        <property name="hibernate.c3p0.idle_test_period">3000</property>
        <!-- 連線池一次增加的連線數 -->
        <property name="hibernate.c3p0.acquire_increment">5</property>
        <!-- 每次都驗證連線是否可用 -->
        <property name="hibernate.c3p0.validate">true</property>
        
        <!-- 是否在控制檯輸出sql語句 -->
        <property name="hibernate.show_sql">true</property>
        
        <!-- 使用xml配置時，指定持久化類xml的路徑 -->
<!--         <mapping resource="org/lcwben/Student.hbm.xml"></mapping> -->
        
        <!-- 使用註解持久化類配置時，指定持久化類.java檔案配置 -->
			<mapping class="org.lcwben.Student" />
    </session-factory>  
</hibernate-configuration>
