用Flex+Spring+Hibernate寫一個登錄

1下載支持文件flex-spring.zip

新建FlexLCDS工程File -> new -> Flex Project 這裏不細說這個。請看http://nic.iteye.com/blog/247604

前端是flex.中間層使用spring接着hibernate，spring+hibernate的集成方法和j2ee的項目中方法相同


修改WEB-INF\web.xml ,加入下面代碼





Xml代碼
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


註冊sping factory，

修改WEB-INF\flex配置


<factory id="springFactory" class="cn.org.coral.core.flex.factory.FlexSpringFactory" />





Class屬性填寫第一步中考入項目SpringFactory類的路徑

3 註冊bean到remoting-config.xml

Xml代碼
<destination id="teacherDao">
<properties>
<factory>springFactory</factory>
<source>TeacherDAO</source>

</properties>
</destination>

<destination id="teacherDao">
<properties>
<factory>springFactory</factory>
<source>TeacherDAO</source>

</properties>
</destination>



編寫SpringFactory.java




Java代碼
public class FlexSpringFactory implements FlexFactory {

public FactoryInstance createFactoryInstance(String id, ConfigMap properties) {
SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties);
instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));
return instance;
}
public Object lookup(FactoryInstance inst) {
SpringFactoryInstance factoryInstance = (SpringFactoryInstance) inst;
return factoryInstance.lookup();
}
public void initialize(String arg0, ConfigMap arg1) {

}

}

public class SpringFactoryInstance extends FactoryInstance
{
public SpringFactoryInstance(FlexSpringFactory factory, String id, ConfigMap properties)
{
super(factory, id, properties);
}
public Object lookup()
{
ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(flex.messaging.FlexContext.getServletConfig().getServletContext());
String beanName = getSource();
try
{
return appContext.getBean(beanName);
}
catch (NoSuchBeanDefinitionException nexc)
{
ServiceException e = new ServiceException();
throw e;
}
catch (BeansException bexc)
{
ServiceException e = new ServiceException();
throw e;
}
}

public class FlexSpringFactory implements FlexFactory {

public FactoryInstance createFactoryInstance(String id, ConfigMap properties) {
SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties);
instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));
return instance;
}
public Object lookup(FactoryInstance inst) {
SpringFactoryInstance factoryInstance = (SpringFactoryInstance) inst;
return factoryInstance.lookup();
}
public void initialize(String arg0, ConfigMap arg1) {

}

}

public class SpringFactoryInstance extends FactoryInstance
{
public SpringFactoryInstance(FlexSpringFactory factory, String id, ConfigMap properties)
{
super(factory, id, properties);
}
public Object lookup()
{
ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(flex.messaging.FlexContext.getServletConfig().getServletContext());
String beanName = getSource();
try
{
return appContext.getBean(beanName);
}
catch (NoSuchBeanDefinitionException nexc)
{
ServiceException e = new ServiceException();
throw e;
}
catch (BeansException bexc)
{
ServiceException e = new ServiceException();
throw e;
