我用hibernate synchronizer按照网上的例子做了一个例子,运行了n天还是没有运行起来
这是我的hbm.xml文件
<?xml version= "1.0 "?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN "
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd " >
<hibernate-mapping package= "edu.yzu ">
<class
name= "Wahaha "
table= "wahaha "
>
<meta attribute= "sync-DAO "> true </meta>
<id name= "Id " type= "Integer " column= "id ">
<generator class= "sequence "/>
</id>
<property
name= "Username "
column= "username "
type= "string "
not-null= "false "
length= "10 "
/>
<property
name= "Password "
column= "password "
type= "string "
not-null= "false "
length= "10 "
/>
</class>
</hibernate-mapping>
下面的是cfg.xml
<?xml version= "1.0 " encoding= "utf-8 "?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN "
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd ">
<hibernate-configuration>
<session-factory>
<!-- local connection properties -->
<property name= "hibernate.connection.url ">
jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=Mydb
</property>
<property name= "hibernate.connection.driver_class ">
com.microsoft.jdbc.sqlserver.SQLServerDriver
</property>
<property name= "hibernate.connection.username "> sa </property>
<property name= "hibernate.connection.password "> guolei </property>
<!-- property name= "hibernate.connection.pool_size "> </property -->
<!-- dialect for Microsoft SQL Server -->
<property name= "dialect ">
org.hibernate.dialect.SQLServerDialect
</property>
<property name= "hibernate.show_sql "> false </property>
<property name= "hibernate.transaction.factory_class ">
org.hibernate.transaction.JDBCTransactionFactory
</property>
<mapping resource= "edu/yzu/Wahaha.hbm.xml " />
</session-factory>
</hibernate-configuration>
最后测试时这个地方老是有问题
_RootDAO.initialize(); /就是这个地方
WahahaDAO persondao = new WahahaDAO();
Wahaha a=new Wahaha();
a.setPassword( "gd ");
a.setUsername( "gd ");
/*SessionFactory sf = new Configuration().configure().buildSessionFactory();
Session sess = sf.openSession();
Transaction tx = sess.beginTransaction();
sess.save( a );
