flask框架实例 开发框架 hibernate3.0 开发实例
  建议是有一点点是一点点基础的人又没有hibernate基础和经验的人比较适合(所谓一点点基础是最起码不要我介绍一些配置文件的什么的 ) 注意我用的JDBC驱动 inet tds TdsDriver    大家一起努力学习吧     建立PO对象    建PO对象Customer Order以及它们的hibernate配置文件    /*  * Created on   *  * TODO To change the template for this generated file go to  * Window Preferences Java Code Style Code Templates  */  package testdemo;    import java util HashSet;  import java util Set;    /**  * @author liuzj  *  * TODO To change the template for this generated type ment go to Window   * Preferences Java Code Style Code Templates  */    public class Customer {  private int id;    private String username;    private String password;    private Set orders = new HashSet();    public Customer() {  }    public Customer(String username String password Set orders) {  this username = username;  this password = password;    this orders = orders;    }    public int getId() {  return id;  }    public String getPassword() {  return password;  }    public String getUsername() {  return username;  }    public Set getOrders() {  return orders;  }    public void setId(int id) {  this id = id;  }    public void setPassword(String password) {  this password = password;  }    public void setUsername(String username) {  this username = username;  }    public void setOrders(Set orders) {  this orders = orders;  }    }    <?xml version= ?>  <!DOCTYPE hibernate mapping PUBLIC   //Hibernate/Hibernate Mapping DTD //EN    mapping dtd >  <hibernate mapping>  <class name= testdemo Customer table= CUSTOMER dynamic insert= true dynamic update= true >  <id name= id column= ID >  <generator class= increment />  </id>  <property name= username column= USERNAME />  <property name= password column= PASSWORD />    <set  name= orders   inverse= true   cascade= save update   >  <key column= CUSTOMER_ID />  <one to many class= testdemo Order />  </set>    </class>  </hibernate mapping>    /*  * Created on   *  * TODO To change the template for this generated file go to  * Window Preferences Java Code Style Code Templates  */  package testdemo;    /**  * @author liuzj  *  * TODO To change the template for this generated type ment go to  * Window Preferences Java Code Style Code Templates  */    import java io Serializable;  public class Order implements Serializable {    private Long id;  private String orderNumber;  private double price;  private Customer customer;    public Order() {  }  public Order(String orderNumber double price Customer customer) {  this orderNumber=orderNumber;  this price=price;  this customer=customer;  }  public Long getId() {  return this id;  }    public void setId(Long id) {  this id = id;  }    public String getOrderNumber() {  return this orderNumber;  }    public void setOrderNumber(String orderNumber) {  this orderNumber = orderNumber;  }    public Customer getCustomer() {  return this customer;  }    public void setCustomer(Customer customer) {  this customer = customer;  }    public double getPrice(){  return this price;  }  private void setPrice( double price ){  this price = price;  }  }    <?xml version= ?>  <!DOCTYPE hibernate mapping PUBLIC   //Hibernate/Hibernate Mapping DTD //EN    mapping dtd >    <hibernate mapping package= testdemo >    <class name= Order  table= ORDERS >    <id name= id >  <generator class= increment />  </id>    <property name= orderNumber column= ORDER_NUMBER />  <property name= price />    <many to one  name= customer   column= CUSTOMER_ID   class= Customer   not null= true   />    </class>  </hibernate mapping>    上面的PO已经建立完成 下面是一个测试类    /*  * Created on   *  * TODO To change the template for this generated file go to  * Window Preferences Java Code Style Code Templates  */  package testdemo;    import java util HashSet;    import hibernate Session;  import hibernate SessionFactory;  import hibernate Transaction;  import hibernate cfg Configuration;    import testdemo Customer;    /**  * @author liuzj  *  * TODO To change the template for this generated type ment go to Window   * Preferences Java Code Style Code Templates  */    public class Test {    SessionFactory sessionFactory = new Configuration(nfigure() addClass(  testdemo Customer class) addClass(Order class) buildSessionFactory();  Session session = sessionFactory openSession();  public void saveCustomer(Customer customer) throws Exception {    Transaction tx = null;  try {  tx = session beginTransaction();  session save(customer);    mit();    } catch (Exception e) {  if (tx != null) {  tx rollback();  }  throw e;  } finally {  session close();  }  }    public void testmethod()throws Exception  {  Customer customer=new Customer( lzhengj new HashSet());  Order order =new Order( Order customer);  Order order =new Order( Order customer);  customer getOrders() add(order );  customer getOrders() add(order );  this saveCustomer(customer);    }    public static void main(String[] args) {    try{  new Test() testmethod();    }catch(Exception e)  {  System out println( this is the testmethod throw exception );  e printStackTrace();  }    }  }    ok 下面是一个hibernate的配置hibernate cfg xml(位于应用目录下面)    <!DOCTYPE hibernate configuration PUBLIC   //Hibernate/Hibernate Configuration DTD //EN    configuration dtd >  <hibernate configuration>  <session factory>  <property name= nnection url >  jdbc:inetdae:localhost: ?charset=gbk&database=hibernate_test  </property>  <property name= nnection driver_class >   inet tds TdsDriver  </property>  <property name= nnection username >  sa  </property>  <property name= nnection password >  aa  </property>  <property name= hibernate dialect >   hibernate dialect SQLServerDialect  </property>  <property name= show_sql >  true  & lishixinzhi/Article/program/Java/ky/201311/28232
