Agendamento de Tarefas Utiliza beans Execução de tempos em tempos Ecolha: menos XML VS menos Acoplamento Timer JDK

package com.targettrust.spring.jdktask; import java.util.Date; import java.util.TimerTask; public class HoraCertaService extends TimerTask{ @Override @SuppressWarnings ( "deprecation" ) public void run() { System. out .println( new Date().getHours() + ":" + new Date().getMinutes() + ":" + new Date().getSeconds() ); } }

<? xml version = "1.0" encoding = "UTF-8" ?> < beans xmlns = "http://www.springframework.org/schema/beans" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation = "http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd" > < bean id = "horaCertaService" class = "com.targettrust.spring.jdktask.HoraCertaService" /> < bean id = "scheduledTask" class = "org.springframework.scheduling.timer.ScheduledTimerTask" lazy-init = "false" >  < property name = "delay" value = "0" />  < property name = "period" value = "1000" />  < property name = "timerTask" ref = "horaCertaService" /> </ bean > </ beans >

Utiliza AOP com AspectJ Abstrações sobre o AspectJ Weaving em runtime Dependências: aspectjweaver.jar aspectjrt.jar

package com.targettrust.spring.aop; public interface Service { public void fazAlgo(); } package com.targettrust.spring.aop; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class ServiceA implements Service{ private static final Log log = LogFactory. getLog (ServiceA. class ); @Override public void fazAlgo() { log .info( "Fiz algo do tipo A" ); } } package com.targettrust.spring.aop; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class ServiceB implements Service{ private static final Log log = LogFactory. getLog (ServiceB. class ); @Override public void fazAlgo() { log .info( "Fiz algo do tipo B" ); } }

Integração com Junit e TestNG Auto-injeção de propriedades Rollback automático após o teste Prove testes integrados sem servidor de aplicação, mas usando transação e banco de dados. Cache

AbstractDependencyInjectionSpringContextTests AbstractAnnotationAwareTransactionalTests: @DirtiesContext : Annotation que faz o mesmo que o método setDirty isso fará que o contexto seja recarregado nesse método. @ExpectedException: Annotation que sinaliza que o método deve retornar um exception específica, se ele não retornar o teste irá falhar. @NotTransactionl : Indica que esse método roda fora do contexto de transações do Spring. @Repeat : Essa annotation recebe um número, por exemplo 5. O Spring irá repitir esse teste 5 vezes. AbstractTransactionalDataSourceSpringContextTests

package com.targettrust.spring.testing; import java.util.Date; import junit.framework.Assert; import org.springframework.test.AbstractDependencyInjectionSpringContextTests; public class TestDataService extends AbstractDependencyInjectionSpringContextTests { private DataService dataService ; public void setDataService(DataService dataService) { this . dataService = dataService; } @Override protected String[] getConfigLocations() { return new String[]{ "classpath:com/targettrust/spring/testing/Spring-beans.xml" }; } @SuppressWarnings ( "deprecation" ) public void testDataDoDataService(){ Date d = dataService .getSysDate(); Date l = new Date(); Assert. assertEquals (d.getDay(),l.getDay()); Assert. assertEquals (d.getMonth(),l.getMonth()); Assert. assertEquals (d.getYear(),l.getYear()); } }

Exposição de beans Pode ser: RMI, JAX-RPC, JMS, Hessian, Burlap, Http Invoker e até mesmo EJB. Para RMI: Serializable Porta na máquina Abstração sob o RMI

package com.targettrust.spring.remoting; import java.util.Date; public interface HoraService { public Date getDate(); } package com.targettrust.spring.remoting; import java.util.Calendar; import java.util.Date; public class HoraServiceImpl implements HoraService{ public Date getDate() { return Calendar. getInstance ().getTime(); } } <? xml version = "1.0" encoding = "UTF-8" ?> < beans xmlns = "http://www.springframework.org/schema/beans" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation = "http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd" > < bean id = "horaService" class = "com.targettrust.spring.remoting.HoraServiceImpl” /> < bean class = "org.springframework.remoting.rmi.RmiServiceExporter” > < property name = "serviceName" value = "Target-HoraService" /> < property name = "service" ref = "horaService" /> < property name = "serviceInterface“ value = "com.targettrust.spring.remoting.HoraService" /> < property name = "registryPort" value = "1199" /> </ bean > </ beans >

Crie um Aspecto para logar todas as chamadas aos dados de um sistema Crie um agendamento com JDK Task que de 5 em 5 segundos manda um e-mail para uma pessoa informando se ouve alguma mudança no sistema. Crie um serviço de calculadora e exporte ele via RMI, faça um porgrama cliente com o suporte de Junit do Spring e suas classes de teste.
