    Hibernate的景象搭建


    一、项目相干的jar包12个：


    antlr-2.7.6.jar


    commons-collections-3.1.jar


    dom4j-1.6.1.jar


    ejb3-persistence.jar


    hibernate3.jar


    hibernate-annotations.jar


    hibernate-commons-annotations.jar


    javassist-3.9.0.GA.jar


    jta-1.1.jar


    log4j-1.2.15.jar


    slf4j-api-1.5.8.jar


    slf4j-log4j12-1.5.8.jar


    还要参加数据库的相干的JDBC驱动的jar包：mysql-connector-java-5.1.25-bin.jar（MySQL），ojdbc14.jar（Oracle）。


    可以到http://www.docjar.com/网站。


    二、设备核心文件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>

    <hibernate-configuration>

    

        <session-factory>

    

            <!-- Database connection settings -->

            <!--mysql settings 

                <property name=connection.driver_class>com.mysql.jdbc.Driver</property> 

            <property name=connection.url>jdbc:mysql://localhost/hibernate</property> 

            <property name=connection.username>root</property> 

            <property name=connection.password>196691</property> 

            -->

            <property name=connection.driver_class>oracle.jdbc.driver.OracleDriver</property>

            <property name=connection.url>jdbc:oracle:thin:＠localhost:1521:orcl</property>

            <property name=connection.username>root</property>

            <property name=connection.password>root</property>

    

    

            <!-- JDBC connection pool （use the built-in） -->

            <!-- <property name=connection.pool_size>1</property> -->

    

            <!-- SQL dialect -->

            <property name=dialect>org.hibernate.dialect.MySQLDialect</property>

    

            <!-- Enable Hibernates automatic session context management -->

            <!-- <property name=current_session_context_class>thread</property> -->

    

            <!-- Disable the second-level cache -->

            <property name=cache.provider_class>org.hibernate.cache.NoCacheProvider</property>

    

    

    

            <!-- Echo all executed SQL to stdout -->

            <property name=show_sql>true</property>

    

    

            <!-- Drop and re-create the database schema on startup -->

            <property name=hbm2ddl.auto>create</property>

    

            <mapping resource=com/qs/hibernate/model/Student.hbm.xml />

            <mapping class=com.qs.hibernate.model.Teacher />

        </session-factory>

    

    </hibernate-configuration>




    三、参加log4j设备文件log4j.properties，将该设备文件拷贝到src下，便于法度调试。



    ＃＃＃ direct log messages to stdout ＃＃＃

    log4j.appender.stdout=org.apache.log4j.ConsoleAppender

    log4j.appender.stdout.Target=System.out

    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
