The document discusses the capabilities of the Spring Framework component model and how it can be used to add functionality to POJO-based applications. It provides an overview of the Spring component model, services, patterns, integration capabilities, and portability. It describes how technologies like dependency injection and AOP enable simple POJO-based programming. It highlights several value adds provided out of the box by Spring, including exporting remote endpoints, JMX support, auditing with aspects, and user extension points. It also discusses XML configuration extensions introduced in Spring 2.0 for higher level abstraction and grouping related beans.
AppFuse is an open source project/application that uses best-of-breed Java open source tools to help you develop web applications quickly and efficiently. Not only does it provide documentation on how to develop light-weight POJO-based applications, it includes features that many applications need out-of-the-box: authentication and authorization, remember me, password hint, skinnability, file upload, Ajax libraries, signup and SSL switching. This is one of the main features in AppFuse that separates it from the other "CRUD Generation" frameworks like Ruby on Rails, Trails and Grails. AppFuse is already an application when you start using it, which means code examples are already in your project. Furthermore, because features already exist, the amount of boiler-plate code that most projects need will be eliminated.
In this session, you will learn Seven Simple Reasons to Use AppFuse. If you don't use it to start your own projects, hopefully you will see that it provides much of the boiler-plate code that can be used in Java-based web applications. Since it's Apache Licensed, you're more than welcome to copy/paste any code from it into your own applications.

2. Aims Understand the capabilities of the Spring Framework component model, and how you can use them to add new power to your POJO-based applications
3. Agenda Spring component model fundamentals Value adds out of the box User extension points Spring 2.0 configuration extensions Spring 2.1: New Scaling out the Spring component model
5. Much More Than an IoC Container… Core component model + Services + Patterns (Recipes) + Integration (Ecosystem) + Portability (Runs everywhere) = Universal POJO programming model Embraced by more and more enterprise vendors
7. Simple POJO public class DefaultWeatherService implements WeatherService { public String getShortSummary(String location) { ... public String getLongSummary(String location) { ... public void update(String location, WeatherData newData) } No special requirements No dependencies on Spring
8. Applying Declarative Transactions <aop:config> <aop:pointcut id="businessService" expression=" execution(* *..*Service+.*(..)) "/> <aop:advisor pointcut-ref="businessService" advice-ref="txAdvice"/> </aop:config> < tx:advice id="txAdvice"> <tx:attributes> <tx:method name="get*" read-only="true"/> <tx:method name="rent*"/> </tx:attributes> </tx:advice> Pointcut identifies business service methods Advice adds behavior. This advice makes business services transactional.
9. Value add: Exporting a Remote Endpoint <bean name="/httpInvoker/weatherService" class="o.sfw...HttpInvokerServiceExporter"> <property name="service" ref="weatherService"/> <property name="serviceInterface" value="com.mycompanyWeatherService“ /> </bean> Can add any number of server side Exporters for each Spring managed bean Don’t need to write any Java™ code
10. Remote Client: POJO public class MyClient { private WeatherService ws; public void setWeatherService(WeatherService ws) { this.ws = ws; } // Business methods omitted }
12. Unit Testing the Dependency Injected Client public void testForMyClient() { MyClient mc = new MyClient(); mc.setWeatherService(myMockService); // Test mc } Can simply inject proxy into client Imagine how much harder testing would be if we had coded the lookup method in the client
13. Value add: Java Management Extensions (JMX™) API Export <bean id="mbeanExporter" class="org.sfw…MBeanExporter"> <property name="beans"> <map> <entry key="i21:service=weatherService"> <ref local=“ weatherService "/> </entry> <!-- other objects to be exported here --> </map> </property> </bean> Can expose any bean as a JMX API MBean without writing JMX API code
14. Extension Point: Auditing Aspect Spring container can weave any managed POJO with aspects This aspect monitors access to the methods that ask for weather summary strings Single code module addresses single requirement (auditing) Type safe with argument binding @Aspect public class WeatherMonitorAuditAspect { @After("execution(String *.WeatherService.*(String)) && args(location) && this(ws)") public void onQuery( String location WeatherService ws) { // Location and WeatherService are bound // to the aspect } } Pointcut identifies the methods that should be affected Advice method contains code to execute
15. Applying the Aspect Ensure an <aop:aspectj-autoproxy/> tag is used to turn on automatic application of any @AspectJ aspects found in the context Simply define the aspect as a Spring bean <bean class=“…WeatherMonitorAuditAspect” />
16. User Extension Points The Spring IoC container provides many extension points Can easily modify the behavior of the container to do custom annotation processing, specific callbacks, validation etc. or even to wrap managed objects in proxies For example: FactoryBean —object configured by the container that creates a component, introducing a level of indirection BeanPostProcessor —called on every bean instantiation BeanFactoryPostProcessor —can modify container metadata BeanDefinition —provides ability to add custom metadata for processing by post processors
17. User Extension Point Example Example: Introducing a LogAware interface Components implementing this are given a log instance The AccountService bean needs a Log : public class AccountService implements LogAware { private Log log; public void setLog(Log log) { this.log = log; } // Business methods omitted... }
18. User Extension Point Example (Cont.) public class LogInjectingBeanPostProcessor implements BeanPostProcessor { public Object postProcessBeforeInitialization( Object bean, String beanName) throws BeansException { if (bean instanceof LogAware) { injectLog((LogAware) bean); } return bean; } public Object postProcessAfterInitialization( Object bean, String beanName) throws BeansException { return bean; } } Called as every bean is initialized Return value can be any object that is type compatible with the bean being processed
19. Activating a BeanPostProcessor Like most Spring IoC extension points, simply define as a bean Automatically gets applied to all other beans Customizes the behavior of the container <bean id=“com.mycompany.LogInjectingPostProcessor” />
20. Agenda Spring component model fundamentals Value adds out of the box User extension points Spring 2.0 configuration extensions Dynamic language support Scaling out the Spring component model
21. XML Configuration Extensions in Spring 2.0: Important New Extension Point A bean definition is a recipe for creating one object Spring 2.0 added the ability to define new XML tags to produce zero or more Spring bean definitions Important new extension point, offering: Higher level of abstraction can simplify many tasks Enables group beans that need to work together into a single configuration unit Can allow existing XML configuration formats to be used to build Spring configuration
22. How Are XML Configuration Extensions Used? Tags out of the box for common configuration tasks Many third party products integrating with Spring Including Java API for XML Web Services (JAX-WS) Reference Implementation User Extensions: Problem-specific configuration Makes it easier to develop and maintain applications Allow XML schema validation Better out of the box tool support Code completion for free Exploit the full power of XML Namespaces, schema, tooling
23. XML Configuration in Spring 2.0 <bean id="dataSource" class="...JndiObjectFactoryBean"> <property name="jndiName" value="jdbc/StockData"/> </bean> <jee:jndi-lookup id="dataSource" jndiName="jdbc/StockData"/>
24. XML Configuration in Spring 2.0 <bean id="properties" class="...PropertiesFactoryBean"> <property name="location" value="jdbc.properties"/> </bean> <util:properties id="properties" location="jdbc.properties"/>
25. Transaction Simplification Specialized tags for making objects transactional Benefit from code assist <tx:annotation-driven /> Code assist for transaction attributes
28. Out-of-the-Box Namespaces AOP JMX API Remoting Scheduling MVC Suggestions and contributions welcome A rich library will build over time
29. Authoring Custom Extensions: Step 1 Write an XSD to define element content Allows sophisticated validation, well beyond DTD Amenable to tool support during development Author with XML tools XML Spy
30. Authoring Custom Extensions: Step 2 Implement a NamespaceHandler to generate Spring BeanDefinitions from element content Helper classes such as BeanDefinitionBuilder to make this easy public interface NamespaceHandler { void init(); BeanDefinition parse(Element element, ParserContext parserContext); BeanDefinitionHolder decorate(Node source, BeanDefinitionHolder definition, ParserContext parserContext); }
31. Authoring Custom Extensions: Step 3 Add a mapping in a META-INF/spring.handlers file http//www.springframework.org/schema/util=org.springframework.beans.factory.xml.UtilNamespaceHandler http//www.springframework.org/schema/aop=org.springframework.aop.config.AopNamespaceHandler http//www.springframework.org/schema/jndi=org.springframework.jndi.config.JndiNamespaceHandler http//www.springframework.org/schema/tx=org.springframework.transaction.config.TxNamespaceHandler http//www.springframework.org/schema/mvc=org.springframework.web.servlet.config.MvcNamespaceHandler
32. Using Custom Extensions Import relevant XSD Use the new elements <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
33. Agenda Spring component model fundamentals Value adds out of the box User extension points Spring 2.0 configuration extensions Spring 2.1 Scaling out the Spring component model
34. What's New in Spring 2.1? Spring 2.1 Allows use of annotations for configuration, as well as XML Can mix and match annotations and XML JCA 1.5 support Further enhancements in JPA support Aims: Make Spring still easier to use
35. Java code: Annotations autoscanned @Component public class FooServiceImpl implements FooService { @Autowired private FooDao fooDao; public String foo(int id) { return fooDao.findFoo(id); } } @Aspect public class ServiceInvocationCounter { private int useCount; @Pointcut("execution(* demo.FooService+.*(..))") public void serviceExecution() {} @Before("serviceExecution()") public void countUse() { this.useCount++; } public int getCount() { return this.useCount; } }
37. One component model Contributions from different sources of configuration XML Java code Internal Java metadata not coupled to configuration format
38. Agenda Spring component model fundamentals Value adds out of the box User extension points Spring 2.0 configuration extensions Spring 2.1 Scaling out the Spring component model
39. Scaling Out Spring Spring can consume objects written in dynamic languages It can also make it easier to scale out applications by deploying and exposing POJOs in new models Examples Other deployment models such as grid SOA with SCA and ESBs OSGi dynamic modularization
40. Scaling POJOs Out to Grid Deployment Spring enables applications to be implemented in POJOs Avoids assumptions about environment in application code Environment changes over time Ignorance is bliss: What your objects don’t know can’t break them if it changes Hence deployment model can change without breaking code Servlet Application Server Standalone client Grid distribution technology…
41. SCA (Service Component Architecture): A Standard for SOA Assembly model Service components, references, wires Policy framework QoS etc. Service implementation and client API Spring Java API C++ BPEL EJB™ architecture Bindings Web Services, Java Message Service (JMS), Java Cryptography Architecture (JCA)
42. The Open SOA Collaboration BEA IBM Oracle SAP Sun Interface21 Red Hat Cape Clear Software IONA Primeton Technologies Sybase Siemens Software AG TIBCO Rogue Wave Software
43. Any Spring Application Is “SCA-ready”… SCA System SCA Component A SCA Component B Spring App Context Bean A Bean B Spring App Context Bean X Bean Y Bean A exposed as service External reference
45. o p e n s r v i c e s t a g w a y a t i v e t i n i 1 1 2 3
46. OSG i The Dynamic Module System for Java technology njection
47. OSGi: A Module System… Partition a system into modules “ Bundles” Strict visibility rules Resolution process Satisfies dependencies of a module Understands versioning!
48. … and It’s Dynamic! Modules can be Installed Started Stopped Uninstalled Updated … at runtime!
49. Spring and OSGi: Complementary Technologies Both are the best at what they do Injection/AOP component model Dynamic runtime infrastructure Both run everywhere Little overlap Natural to combine dynamic power of OSGi with ease of use of Spring component model Spring/OSGi integration likely to make its way into OSGi specifications
50. Spring OSGi—Project Goals Use Spring container to configure modules (bundles) Make it easy to publish and consume services Across a number of bundles Enable applications to be coded without dependency on OSGi APIs Easy unit and integration testing Provide the needed bundles and infrastructure to deploy OSGi-based applications to application servers
51. Project Collaborators Led by Interface21 Committers from BEA and Oracle also active on the project Input to the specification and direction from OSGi Alliance (technical director and CTO) BEA, Oracle, IBM Eclipse Equinox Felix and many individuals
52. OSGi Packaging for Spring Spring modules packaged as OSGi bundles Spring-core Spring-beans Spring-aop Etc. All the necessary import and export package headers defined Enables an OSGi application to import and use Spring packages and services Currently done in Spring-OSGi project Spring module jars will come this way “out of the box” in Spring 2.1
53. Spring Makes It Easy! Exporting a service: <osgi:service id="simpleServiceOsgi" ref="simpleService" interface= "org.sfw.osgi.samples.ss.MyService"/> Importing a service: <osgi:reference id="aService" interface= "org.sfw.osgi.samples.ss.MyService"/>
56. Versioning MVC MVC’ S R Two versions of the same service types… at the same time! S’
57. The Spring Portfolio Spring Framework Spring WebFlow Spring Web Services Spring Security Spring Rich Client Spring LDAP Spring IDE Spring OSGi Spring Modules Spring.NET Takes familiar Spring concepts to a wide range of areas Consistent themes of Simplicity and Power
58. Summary Spring provides a highly extensible component model POJOs used as “Spring beans” in a Spring application benefit from many potential services for free Many value adds out of the box Many extension points for users The Spring component model is ready for the challenges of tomorrow. Build out directions include: Dynamic language support SCA OSGi
