好久沒用j2ee開發呢，昨天寫呢乙個hibernate的對映,幾次出現異常，翻呢一遍書熟悉呢一下才搞定，這裡把幾種常用的對映放上來，希望大家方便查詢：
一:hibernate 單向一對多對映 乙個team 對應多個student；
（一）:hibernate.cfg.xml
public "-//hibernate/hibernate configuration dtd//en"
"">
jdbc:mysql://localhost:3306/test
com.mysql.jdbc.driver
root
admin
org.hibernate.dialect.mysqldialect
true
org.hibernate.transaction.jdbctransactionfactory
（二）;team.hbm.xml
(三):student.hb,.xml
（四）測試類
package hibernate.dao;
import org.hibernate.session;
import org.hibernate.transaction;
public class one_manydao
}（五）hibernatesessionfactory封裝呢session
package hibernate.dao;
import org.hibernate.hibernateexception;
import org.hibernate.session;
import org.hibernate.cfg.configuration;
/**
* configures and provides access to hibernate sessions, tied to the
# * current thread of execution. follows the thread local session
# * pattern, see .
# */
public class hibernatesessionfactory
/**
# * returns the threadlocal session instance. lazy initialize
# * the sessionfactory if needed.
# *
# * @return session
# * @throws hibernateexception
# */
public static session getsession() throws hibernateexception
session = (sessionfactory != null) ? sessionfactory.opensession()
: null;
threadlocal.set(session);
}return session;
}/**
# * rebuild hibernate session factory
# *
# */
public static void rebuildsessionfactory() catch (exception e)
}/**
# * close the single hibernate session instance.
# *
# * @throws hibernateexception
# */
public static void closesession() throws hibernateexception
}/**
# * return session factory
# *
# */
public static org.hibernate.sessionfactory getsessionfactory()
/**
# * return session factory
# *
# * session factory will be rebuilded in the next call
# */
public static void setconfigfile(string configfile)
/**
# * return hibernate configuration
# *
# */
public static configuration getconfiguration()
}
