    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
    log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{
    1}:%L - %m%n

    ### direct messages to file hibernate.log ###
    #log4j.appender.file=org.apache.log4j.FileAppender
    #log4j.appender.file.File=hibernate.log
    #log4j.appender.file.layout=org.apache.log4j.PatternLayout
    #log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{
    1}:%L - %m%n

    ### set log levels - for more verbose logging change
    info to debug ###

    log4j.rootLogger=warn, stdout

    #log4j.logger.org.hibernate=info
    #log4j.logger.org.hibernate=debug

    ### log HQL query parser activity
    #log4j.logger.org.hibernate.hql.ast.AST=debug

    ### log just the SQL
    #log4j.logger.org.hibernate.SQL=debug

    ### log JDBC bind parameters ###
    #log4j.logger.org.hibernate.type=info
    #log4j.logger.org.hibernate.type=debug

    ### log schema export/ ###
    log4j.logger.org.hibernate.tool.hbm2ddl=debug

    ### log HQL parse trees
    #log4j.logger.org.hibernate.hql=debug

    ### log cache activity ###
    #log4j.logger.org.hibernate.cache=debug

    ### log transaction activity
    #log4j.logger.org.hibernate.transaction=debug

    ### log JDBC resource acquisition
    #log4j.logger.org.hibernate.jdbc=debug

    ### enable the following line if you want to track down connection ###
    ### leakages when using DriverManagerConnectionProvider ###
    #log4j.logger.org.hibernate.connection.DriverManagerConnectionProvider=trace
