2. Agenda
•Concept
– IOC(Inverse of Control and Dependency Injection)
– AOP(Aspect-Oriented Programming)
•Core Technologies
– Architecture
– Xml v.s. Annotation
– SpEL
– Testing
•Integration
– CXF(web services and restful services)

3. IOC
•IOC Type
•Type 1 : interface injection
•Type 2 : setter injection
•Type 3 : constructor injection

8. AOP
@Aspect
class BeforeExample {
@Before("execution(* com.xyz.myapp.dao.*.*(..))")
public void doAccessCheck() {
// ...
}
}
@Aspect
class AfterReturningExample {
@AfterReturning("com.xyz.myapp.SystemArchitecture.dataAcc
essOperation()")
public void doAccessCheck() {
// ...
}
}

9. AOP
@Aspect
class AroundExample {
@Around("com.xyz.myapp.SystemArchitecture.businessService
()")
public Object doBasicProfiling(ProceedingJoinPoint pjp)
throws Throwable {
// start stopwatch
Object retVal = pjp.proceed();
// stop stopwatch
return retVal;
}
}

10. Pointcut designator
• execution(modifiers-pattern? ret-type-pattern declaring-type-pattern? name-
pattern(param-pattern) throws-pattern?)
• execution(public * *(..))
• execution(* com.xyz.service.AccountService.*(..))
• within(com.xyz.service.*)
• within(com.xyz.service..*)
• this(com.xyz.service.AccountService)
• target(com.xyz.service.AccountService)

16. Xml v.s. Annotation
public class SimpleMovieLister {
private MovieFinder movieFinder;
public void find() {
movieFinder.find();
}
public void setMovieFinder(MovieFinder
movieFinder) {
this.movieFinder = movieFinder;
}
}
Trend Micro Confidential

17. Xml v.s. Annotation
<bean id="movieFinder" class="com.sample.MovieFinder"/>
<bean id="simpleMovieLister”
class="com.sample.SimpleMovieLister">
<property name="movieFinder">
<ref local="movieFinder"/>
</property>
</bean>
Trend Micro Confidential

18. Xml v.s. Annotation
@Service
public class SimpleMovieLister {
@Resource
private MovieFinder movieFinder;
public void find() {
movieFinder.find();
}
}
Trend Micro Confidential

19. Xml v.s. Annotation
• stereotype annotations
• @Component
• @Service
• @Controller
• @Repository
Controller Service Repository
Trend Micro Confidential

20. SpEL
• Literal expressions
• Properties, Arrays, Lists, Maps, Indexers
• Methods
• Operators
• Assignment
• Types
• Constructors
• Variables
• User defined functions
• Ternary Operator
• Elvis Operator
• Safe Navigation operator
• Collection Selection
• Collection Projection
• Expression templating

21. Testing
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations =
{ "classpath:appContext_core.xml",
"classpath:appContext_index.xml”})
public abstract class AbstractTestCase {
}
Trend Micro Confidential

22. Testing
• Spring-specific annotations
– @TransactionConfiguration
– @BeforeTransaction
– @AfterTransaction
– @IfProfileValue
– @ExpectedException
– @Timed
– @Repeat
Trend Micro Confidential

23. CXF
• JAX-WS Support
– SOAP 1.1, 1.2
• RESTful services
– JSON & XML support
• WS-* Support
– WS-Addressing, WS-Policy, WS-ReliableMessaging
and WS-Security
• Spring Integration
• Bus
– Fast Infoset
Trend Micro Confidential

24. CXF
• RESTful services
– JAX-RS
– JAX-WS Provider and Dispatch
– HTTP Binding(deprecated)
Trend Micro Confidential

25. CXF
• Parameters
– @PathParam
– @QueryParam
– @HttpHeader
– @MatrixParam
– @FormParam
– @CookieParam
– PathSegment
