jbpm中的hibernate :: jander的java学习笔记

jbpm中，提供了两个类对Hibernate进行了包装，org.jbpm.util.db.Db和org.jbpm.util.db.DbSession.

Db提供下面两个方法对session进行管理。

  public static void configureSessionFactory( String resource ) {...}
 
  public static DbSession openSession( String SessionFactoryJndiName ){... }

 

DbSession提供了很多hibernate的数据管理方法。

 public Collection filter(Object collection, String filter) {
  ...
  }
  
  public Collection filter(Object collection, String filter, Object[] values, Type[] types) {...}
  
  public Query getNamedQuery(String queryName) {...}
 
  public Query createFilter(Object collection, String queryString) {...}

  public Query createQuery(String queryString) {...}
   
  public Object load(Class theClass, Serializable id) {...} 

  public List find(String query) {...}

  public Object findOne(String query) {...}
  
  public Object findOne(String query, Object value, Type type) {...}

  public Iterator iterate(String query) {...} 

 public Object iterateOne(String query) {...}  
 
  public LockMode getCurrentLockMode(Object object) {...}
 
  public void lock(Object object, LockMode lockMode) {...}
 
  public FlushMode getFlushMode() {...}
 
  public void setFlushMode(FlushMode flushMode) {...}
 
  public Serializable getIdentifier(Object object) {...}
 
  public boolean isConnected() {...} 
 
  public boolean isOpen()  {...} 
 
  public void delete(Object object) {...}
 
  public int delete(String query) {...}
  
  
  public int delete(String query, Object value, Type type) {...}

     
  public void save(Object object, Serializable id) {... }
 
  public void saveOrUpdate(Object object) {...} 

  public void update(Object object, Serializable id) {...}
 
  public void flush() {...}

....

用这两个类，对Hibernate数据对象的处理就更简单了。

以前听说有人写过生成对Hibernate数据对象进行edit,delete,save方法生成的插件。jbpm的方法比这种方法更好。
