Another framework? How much work is it to convert an existing project (like jpetstore)?
-----Original Message----- From: Poitras Christian [mailto:[EMAIL PROTECTED] Sent: 12 April 2007 03:57 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: converting iBATIS framework DAOs to the Spring Framework I also suggest to use Stripes to cut the size of Spring config file. By adding @SpringBean annotation in front of properties (event private), Stripes will fill these properties by simulating the auto-wire process of Spring (even if no setter/getter/constructor exists). For instance, if I have a class like this /** * Manage DataFile. * * @author poitrac */ public class DataFileManagement { public DataFileManagement() { super(); } /** * For DataFile management. */ @SpringBean private DataFileDao dataFileDao; /** * Hides DataFiles. * @param dataFileList DataFiles to hide from search requests. */ @Transactional public synchronized void hide(List<DataFile> dataFileList) { dataFileDao.hide(dataFileList); } } Then I have no special configuration to do in spring.xml beside declaring the bean. <bean id="dataFileManagement" class="ca.qc.ircm.management.DataFileManagement"/> It's possible to use the feature without using the web framework of Stripes. To do so, you juste need to add a PostProcessor. /** * Injection bean dependencies based on Annotation. * * @author poitrac */ public class AnnotationInjector implements BeanPostProcessor, ApplicationContextAware, Ordered { public AnnotationInjector() { super(); } /** * ApplicationContext for bean injection. */ private ApplicationContext applicationContext; /* (non-Javadoc) * @see org.springframework.beans.factory.config.BeanPostProcessor#postProcessBe foreInitialization(java.lang.Object, java.lang.String) */ public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException { return bean; } /* (non-Javadoc) * @see org.springframework.beans.factory.config.BeanPostProcessor#postProcessAf terInitialization(java.lang.Object, java.lang.String) */ public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException { SpringHelper.injectBeans(bean, applicationContext); return bean; } /* (non-Javadoc) * @see org.springframework.core.Ordered#getOrder() */ public int getOrder() { return Ordered.HIGHEST_PRECEDENCE; } /* * (non-Javadoc) * @see org.springframework.context.ApplicationContextAware#setApplicationContex t(org.springframework.context.ApplicationContext) */ public void setApplicationContext(ApplicationContext applicationContext) { this.applicationContext = applicationContext; } } Here I use HIGHEST_PRECEDENCE since Stripes requires to set properties (without setters) before it is enhanced by cglib. I prefer to just declare my beans in Spring and update my code and not the xml file (I always forget about updating xml anyway...).
