本文指导你如何使用最新的Hibernate Synchronizer来与spring框架集成。（认为你已经安装好Hibernate Synchronizer）。
有五种实现方法,下面介绍如何把Hibernate3与spring以及Hibernate Synchronizer。希望对你有所帮助，可以参照 Hibernate Synchronizer and Spring
第一步更新某一项目的Hibernate Synchronizer设置
设置Hibernate Synchronizer设置使用用户的base root。
菜单:
Project->Properties->Hibernate Synchronizer->Data Access
Objects tab->选中 “I would like to use a custom root” 并输入
SpringBaseRootDAO全路径; 例如com.codesponsors.data.dao.SpringBaseRootDAO.
import org.hibernate.Criteria;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.springframework.dao.DataAccessException;
import org.springframework.orm.hibernate3.HibernateTemplate;
/** *//**
* Based on Hibernate Synchronizer
* For more information or documentation, visit The Hibernate Synchronizer page
* at http://www.binamics.com/hibernatesync or contact Joe Hudson at joe@binamics.com.
*
* @author Joe Hudson
* @author Todd McGrath mcgrath@supergloo.com
*/
public abstract class SpringHibernate3BaseRootDAO extends HibernateTemplate ...{
/** *//**
* Return the name of the configuration file to be used with this DAO or null if default
*/
public String getConfigurationFileName () ...{
return null;
}
/** *//**
* Return the specific Object class that will be used for class-specific
* implementation of this DAO.
* @return the reference Class
*/
protected abstract Class getReferenceClass();
/** *//**
* Return a Criteria object that relates to the DAO's table
*/
protected Criteria createCriteria (Session s) throws DataAccessException ...{
return s.createCriteria(getReferenceClass());
}
/** *//**
* Return a Criteria object that relates to the DAO's table
*/
public Criteria createCriteria () throws HibernateException ...{
Session s = getSessionFactory().openSession();
return s.createCriteria(getReferenceClass());
}
/** *//**
* Return the property of the class you would like to use for default ordering
* @return the property name
*/
public String getDefaultOrderProperty () ...{
return null;
}
}
；.更新 Hibernate Synchronizer 使用用户异常类. 同一个界面. 输入 “org.springframework.dao.DataAccessException” 在DAO异常输入框
第二步更新所有项目的Hibernate Synchronizer全局设置
1. Eclipse 菜单, 点击Window->Preferences
2. 在左边控制板上点击Hibernate Synchronizer
3. 选择Snippets
4. 更新 Base DAO Snippets
a) 打开Base DAO
b) 替换action方法为
/** *//**
* Persist the given transient instance, first assigning a generated identifier. (Or using the current value
* of the identifier property if the assigned generator is used.)
* @param ${class.VarName} a transient instance of a persistent class
* @return the class identifier
*/
public $...{class.ParentRoot.Id.Property.ObjectClass} save($...{class.AbsoluteValueObjectSignatureClassName} $...{class.VarName})
#if ($exceptionClass)
throws $...{exceptionClass} ...{
#else
...{
#end
return ($...{class.ParentRoot.Id.Property.ObjectClass}) super.save($...{class.VarName});
}
/** *//**
* Either save() or update() the given instance, depending upon the value of its identifier property. By default
* the instance is always saved. This behaviour may be adjusted by specifying an unsaved-value attribute of the
* identifier property mapping.
* @param ${class.VarName} a transient instance containing new or updated state
*/
public void saveOrUpdate($...{class.AbsoluteValueObjectSignatureClassName} $...{class.VarName})
#if ($exceptionClass)
throws $...{exceptionClass} ...{
#else
...{
#end
super.saveOrUpdate($...{class.VarName});
}
/** *//**
* Update the persistent state associated with the given identifier. An exception is thrown if there is a persistent
* instance with the same identifier in the current session.
* @param ${class.VarName} a transient instance containing updated state
*/
public void update($...{class.AbsoluteValueObjectSignatureClassName} $...{class.VarName})
#if ($exceptionClass)
throws $...{exceptionClass} ...{
#else
...{
#end
super.update($...{class.VarName});
}
c) 替换finder方法为
#if ($class.ParentRoot.Id)
public $...{class.AbsoluteValueObjectSignatureClassName} load($...{class.ParentRoot.Id.Property.AbsoluteSignatureClassName} key)
#if ($exceptionClass)
throws $...{exceptionClass} ...{
#else
...{
#end
#if ($class.ParentRoot.Id.Property.isPrimitive())
return ($...{class.AbsoluteValueObjectSignatureClassName}) load(getReferenceClass(), new $...{class.ParentRoot.Id.Property.ObjectClass}(key));
#else
return ($...{class.AbsoluteValueObjectSignatureClassName}) load(getReferenceClass(), key);
#end
}
#end
#if ($class.ParentRoot.Id)
public $...{class.AbsoluteValueObjectSignatureClassName} get($...{class.ParentRoot.Id.Property.AbsoluteSignatureClassName} key)
#if ($exceptionClass)
throws $...{exceptionClass} ...{
#else
...{
#end
#if ($class.ParentRoot.Id.Property.isPrimitive())
return ($...{class.AbsoluteValueObjectSignatureClassName}) get(getReferenceClass(), new $...{class.ParentRoot.Id.Property.ObjectClass}(key));
#else
return ($...{class.AbsoluteValueObjectSignatureClassName}) get(getReferenceClass(), key);
#end
}
#end
#if ($class.ParentRoot.Id)
public java.util.List loadAll()
#if ($exceptionClass)
throws $...{exceptionClass} ...{
#else
...{
#end
return loadAll(getReferenceClass());
}
#end
d) 替换为下面的导入:
import ${class.DAOPackage}.${class.DAOClassName};
e) 替换 Required方法为(从snippets去掉JRE 1.5 特有的属性)
public Class getReferenceClass () ...{
return $...{class.AbsoluteValueObjectClassName}.class;
}
#if ($class.ConfigFile)
/** *//**
* Return the name of the configuration file to be used with this DAO
*/
public String getConfigurationFileName () ...{
return "${class.ConfigFile}";
}
#end
/** *//**
* Cast the object as a ${class.AbsoluteValueObjectSignatureClassName}
*/
public $...{class.AbsoluteValueObjectSignatureClassName} cast (Object object) ...{
return ($...{class.AbsoluteValueObjectSignatureClassName}) object;
}
f) 类的构造函数替换为:
public ${class.BaseDAOClassName} () {}
5) 更新 Root DAO Snippets
a) 打开Root DAO
b) 构造函数替换为:
public _RootDAO () {}
6) 更新 Base Root DAO Snippets
a) 打开Base Root DAO
b) 构造函数替换为:
public _BaseRootDAO () {}
7) 更新DAO Snippets
a) 打开DAO
b) 类定义替换为:
public class ${class.DAOClassName} extends ${class.BaseDAOClassName} {
c) 类构造函数替换为:
public ${class.DAOClassName} () {}
第三步生成配置Hibernate mapping文件
1) 在类路径生成Hibernate Mapping 文件. 参考文章: Generating a Hibernate Mapping file with Hibernate Synchronizer in Eclipse .
2) 打开 Hibernate Mapping文件修改元素 sync-DAO 属性 false 为true
3) 右键点击Hibernate Mapping 文件, 选择 Hibernate Synchronizer -〉Synchronize Files. 在资源文件夹里对应包路径下生成java文件.
第四步删除接口
删除生成的借口文件。例如，如果base包是com.codesponsors.data，删除com.codesponsors.data.dao.iface包。
虽然使用接口和实现由众多的优点. 但是, 借口已经在 DAO 模式中被滥用尤其在使用
Hibernate时. 概念上, Hibernate是实现，DAO 类是接口. Hibernate Synchronizer
最新版本中的接口在我的项目中没有发挥作用，这个问题以后在讨论
第五步配置spring文件
1)配置DAO(s) 为Hibernate模板的 “sessionFactory” 属性加入 LocalSessionFactory (SpringBaseRootDAO 扩展 Hibernate模板). 例如, applicationContext.xml 可能是
<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="mappingResources">
<list>
<value>Users.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<!-- prop key="hibernate.connection.pool_size"></prop -->
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.use_outer_join">true</prop>
<prop key="hibernate.connection.release_mode">on_close</prop>
<!-- <prop key="hibernate.cglib.use_reflection_optimizer">false</prop> -->
</props>
</property>
<property name="dataSource">
<ref bean="dataSource"/>
</property>
</bean>
<bean id="usersDataAccessObject" class="com.codesponsors.data.dao.UsersDAO">
<property name="sessionFactory><ref local="mySessionFactory"/></property>
</bean>
结论
希望上文对你有所帮助
注 - 我希望提供一个简化的Hibernate Synchronizer版本 针对Spring框架用户. Joe 已经提供了这种功能, 但是不知道他将向哪个方向发展
----------------------------------------------------------------------------------------------------------------------------------------------------------
我的使用：
第一步：修改snippets中base root Dao中Session methods使用到的jdk1.5新特性泛型（Generics）的代码；
第二步：修改了插件中的template：MappingWizard.vm的sync-DAO属性为true，可以生成DAO
第三步：在配置全局模板的时候选中SpringConfig，可以生成代码的时候生成spring配置文件
