查了半天的資料，終于搞清楚了如何在hibernate+spring的框架下對DAO層和service層進行測試了。我把自己的經驗總結一下，希望對大家有所幫助。
最重要的是applicationContext.xml的配置，
dao的配置如下
<bean id="CfmStorageRecordDAO"
class="com.finegold.digimus.dao.imp.CfmStorageRecordDAOImp">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
如果是這樣的話，對于dao的測試，我想應該沒有什么問題；
首先你的測試類應該繼承AbstractTransactionalSpringContextTests這個類，覆蓋他的一個方法;getConfigLocations
如下所示
public class ArticleDataDaoTest extends AbstractTransactionalSpringContextTests {
protected String[] getConfigLocations() {
return new String[] { "classpath:applicationContext.xml" };
}
CfmCatalogArticleDataDAO cfmCatalogArticleDataDAO;
CfmCatalogMediaDAO media;
public CfmCatalogMediaDAO getMedia() {
return media;
}
public void setMedia(CfmCatalogMediaDAO media) {
this.media = media;
}
public CfmCatalogArticleDataDAO getCfmCatalogArticleDataDAO() {
return cfmCatalogArticleDataDAO;
}
public void setCfmCatalogArticleDataDAO(
CfmCatalogArticleDataDAO cfmCatalogArticleDataDAO) {
this.cfmCatalogArticleDataDAO = cfmCatalogArticleDataDAO;
}
public void testTreeView() {
List list = cfmCatalogArticleDataDAO.getFormalListByCataTypeIdAndName(
null, "01", -1, -1);
assertTrue(list.size() != 0);
}
}
然后直接運行就可以了，在這個過程中涉及到的所有事務都回RollBack.()
,我覺得這個功能不錯。
**********************************************************************************************
對于service層的測試，由于我們在service層引用了Dao,而且service層配置了事務，呵呵，我的事務是聲明式的。首先看事務的定義：
<bean id="txProxyTemplate" abstract="true" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref local="myTransactionManager"/>
</property>
<property name="transactionAttributes">
<props>
<prop key="create*">PROPAGATION_REQUIRED,-com.finegold.digimus.exception.DigimusException</prop>
<prop key="save*">PROPAGATION_REQUIRED,-com.finegold.digimus.exception.DigimusException</prop>
<prop key="remove*">PROPAGATION_REQUIRED,-com.finegold.digimus.exception.DigimusException</prop>
<prop key="update*">PROPAGATION_REQUIRED,-com.finegold.digimus.exception.DigimusException</prop>
<prop key="del*">PROPAGATION_REQUIRED,-com.finegold.digimus.exception.DigimusException</prop>
<prop key="*">PROPAGATION_REQUIRED,readOnly</prop>
</props>
</property>
</bean>
事務管理器的定義：
<bean id="myTransactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref local="sessionFactory"/>
</property>
</bean>
原來service層對事務的定義：
<bean id="usersTarget" class="com.finegold.digimus.service.imp.UsersServiceImp">
<property name="usersDAO">
<ref local="SfmUsersDAO"/>
</property>
</bean>
<bean id="usersService" parent="txProxyTemplate">
<property name="target">
<ref local="usersTarget"/>
</property>
</bean>
問題就出在這里，如果是這樣定義的話，測試的時候一直出錯，錯誤如下，
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'com.finegold.digimus.dao.imp.test.UserDaoTest':
Unsatisfied dependency expressed through bean property 'userService':
Set this property value or disable dependency checking for this bean.

解決辦法：將service層的bean定義改寫為如下的方式：
<bean id="usersService" parent="txProxyTemplate">
<property name="target">
<bean class="com.finegold.digimus.service.imp.UsersServiceImp">
<property name="usersDAO"> <ref local="SfmUsersDAO"/></property>
</bean>
</property>
</bean>
，然后就可以向dao一樣，寫service層的測試了，不過你要把相應的dao接口改為service的接口哦。
呵呵，好了，祝你成功!
