用ecplice的java ee 版本配置hibernate的步骤

导入jar包：

antlr-2.7.6.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
hibernate3.jar
javassist-3.9.0.GA.jar
jta-1.1.jar
slf4j-api-1.5.8.jar

（hibernate的jar：hibernate-annotations-3.4.0.GA、hibernate-distribution-3.3.2.GA)

ojdbc14.jar(我用的数据库是oracle11版本的jar)

再就绪配置如下：

hibernate.cfg.xml：（之前是方言没写，导致启动不了hibernate）

<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <!-- 数据库连接配置  -->
        <!-- 驱动类 -->
        <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
        <!-- 连接字符串 -->
        <property name="connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property>
        <!-- 用户名密码 -->
        <property name="connection.username">scott</property>
        <property name="connection.password">tiger</property>
        <property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
        <!-- 显示sql语句 -->
        <property name="show_sql">true</property>
        <property name="hbm2ddl.auto">create</property>
        <!-- 配置映射文件 -->
        <mapping resource="com/entity/User.hbm.xml"/>
        
    </session-factory>
</hibernate-configuration>

User.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.entity.User" table="t_user">
        <id name="username" type="java.lang.String" length="10" column="USERNAME">
        <generator class="sequence">
                 <param name="sequence">seq_gid</param>
             </generator>
        </id>
        <property name="password" type="java.lang.String" column="PASSWORD"/>
    </class>    
</hibernate-mapping>
