17 Controller

18

19 Controller Interface public interface Controller {
ModelAndView handleRequest( HttpServletRequest request, HttpServletResponse response) throws Exception; }

20 HelloWorldController
실습 HelloWorldController public class HelloWorldController implements Controller { public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception { return new ModelAndView("hello", "message", "Hello World!! Welcome to Page!!"); } action-servlet.xml <bean id="helloController“ class="net.javajigi.web.HelloWorldController" /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/> <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="urlMap"> <map> <entry key="/hello.do" value-ref="helloController"/> </map> </property> </bean>

21 2 3 1 4 5 6 SimpleUrlHandlerMapping “hello” /hello.do
DispatcherServlet HelloWorldController ModelAndView 1 4 “hello”, “message” 5 InternalResourceViewResolver 6 /WEB-INF/jsp/hello.jsp

22 UrlFilenameViewController
= No Model 데이터 정적인 페이지

23 org.springframework.web.servlet.mvc.UrlFilenameViewController
실습 org.springframework.web.servlet.mvc.UrlFilenameViewController action-servlet.xml <bean id="staticViewController" class="org.springframework.web.servlet.mvc.UrlFilenameViewController" /> <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="urlMap"> <map> <entry key="/**/*.html" value-ref="staticViewController"/> </map> </property> </bean>

24 MultiActionController DispatchAction of Struts
= DispatchAction of Struts Action of Webwork

25 = 1 : 1 ListAction InsertAction UpdateAction ViewAction DeleteAction
List.do B R O W S E ListAction Insert.do InsertAction Update.do UpdateAction View.do ViewAction Delete.do DeleteAction = 1 : 1 URL : Action

26 단점 URL이 추가될 때마다 Action(Controller)를 추가해야함.
Action(Controller)가 추가될 때마다 설정 파일에 Action 정보 추가 하나의 URL이 추가될 때마다 추가되어야 하는 부분이 많아짐으로서 생산성 저하. Action(Controller)의 숫자가 많아질수록 유지보수의 어려움. 너무도 복잡한 설정 파일로 인해 유지보수의 어려움.

27 = N : 1 SampleAction URL : Action B R O W S E List.do Insert.do
Update.do View.do Delete.do = N : 1 URL : Action

28 실습 - MultiActionController
UserController public class UserController extends MultiActionController { public ModelAndView list(HttpServletRequest request, HttpServletResponse response) throws Exception { List<User> userList = userService.findUserList(); ModelAndView mav = new ModelAndView(); mav.addObject("users", userList); return mav; } public ModelAndView edit(HttpServletRequest request, HttpServletResponse response) User user = new User(); bind(request, user); userService.updateUser(user); return new ModelAndView("redirect:/user/list.do");

29 URL Mapping : InternalPathMethodNameResolver
설정 파일에 아무 것도 설정되어 있지 않을 경우 InternalPathMethodNameResolver가 Default URL에 포함되어 있는 Method 이름을 실행한다. => UserController의 edit() 메써드 호출 일반적으로 가장 많이 사용한다.

30 URL Mapping : ParameterMethodNameResolver
action-servlet.xml <property name="methodNameResolver"> <bean class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver"> <property name="paramName" value="method"/> </bean> </property> URL을 통하여 전달되는 인자 이름을 통하여 실행하는 메써드 결정 => UserController의 edit() 메써드 호출

31 URL Mapping : PropertiesMethodNameResolver
action-servlet.xml <bean id="propsResolver" class="org....mvc.multiaction.PropertiesMethodNameResolver"> <property name="mappings"> <value> /user/modify.do=edit /user/list.do=list /user/remove.do=delete </value> </property> </bean> 요청 URL과 실행 메써드를 Mapping한다. Properties 파일을 통하여 관리하는 것도 가능하다. => UserController의 edit() 메써드 호출

35 Spring MVC의 Interceptor
public interface HandlerInterceptor { boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception; void postHandle( HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) void afterCompletion( Exception ex) }

36 실습 - SignonInterceptor
public class SignonInterceptor extends HandlerInterceptorAdapter { public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { User userSession = (User) WebUtils.getSessionAttribute(request, "user"); if (userSession == null) { String url = request.getServletPath(); String query = request.getQueryString(); ModelAndView modelAndView = new ModelAndView("redirect:/signon/login.html"); if (query != null) { modelAndView.addObject("signonForwardAction", url+"?"+query); } else { modelAndView.addObject("signonForwardAction", url); throw new ModelAndViewDefiningException(modelAndView); return true;

37 실습 - SignonInterceptor
action-servlet.xml <bean id="signonInterceptor" class="net.javajigi.user.web.SignonInterceptor"/> <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="interceptors"> <list> <ref bean="signonInterceptor"/> </list> </property> <property name="urlMap"> <map> <entry key="/user/*.do" value-ref="userController"/> <entry key="/signon/logout.do" value-ref="signonController"/> </map> </bean>

38 HandlerMapping

39

40 BeanNameUrlHandlerMapping
<bean name="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> <bean name="/menu.do" class="net.javajigi.common.web.MenuController" /> <bean name="/changelocale.do" class="net.javajigi.common.web.SessionLocaleController" /> URL과 Controller 설정을 한 곳에서 할 수 있다. 다양한 Interceptor 설정을 하는 것이 힘들다.

41 SimpleUrlHandlerMapping
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="urlMap"> <map> <entry key="/**/*.html" value-ref="staticViewController"/> <entry key="/user/addForm.do" value-ref="userController"/> <entry key="/user/add.do" value-ref="userController"/> <entry key="/signon/login.do" value-ref="signonController"/> <entry key="/hello.do" value-ref="helloController"/> </map> </property> </bean> 다양한 Interceptor 설정을 하는 것이 가능하다. URL 설정과 Controller 설정이 분리되어 있다.

42 ControllerClassNameHandlerMapping
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" /> <bean id="viewNameTranslator" class="org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator" /> HelloWorldController => helloworld.do HelloWorldController.hello => helloworld/hello.do

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> <context:component-scan base-package="net.javajigi"/> @Controller public class UserController { @RequestMapping("/user/list.do") public ModelMap listHandler() { List<User> userList = userService.findUserList(); return new ModelMap("users", userList); }

44 여러 개의 HandlerMapping 사용
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping" p:order="1"> <property name="urlMap"> <map> <entry key="/**/*.html"> <ref local="staticViewController" /> </entry> </map> </property> </bean> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" p:order="2"/> <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" p:order="3" />

51 여러 개의 ViewResolver 사용하기
<bean class="org.springframework.web.servlet.view.ResourceBundleViewResolver" p:basename="views" p:order="1"/> <bean class="org.springframework.web.servlet.view.XmlViewResolver" p:location="/WEB-INF/views.xml" p:order="2"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:viewClass="org.springframework.web.servlet.view.JstlView" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" p:order="3"/>

86 Join point 프로그램이 실행되는 중 식별할 수 있는 Point.
예를 들어 메써드의 실행, Exception Handling 등이 포함된다.

87 Advice Join Point에서 Aspect에 의하여 실행되는 Action을 의미
예를 들어 Profiling Aspect일 경우 Join Point에서 Profiling 하는 것을 의미한다.

88 Pointcut Join Point들을 선택하는 규칙을 정의하는 것. Weaving Rule을 정의하는 것

89 Target Object 애플리케이션의 핵심 비즈니스 로직을 구현하고 있는 Object
Aspect에 의하여 Advice가 적용되는 Object

90 Aspect 하나의 Crosscutting Concern을 Aspect로 정의 가능
Advice와 Pointcut이 결합되어 Aspect가 된다. 예를 들어 Transaction, Security등이 하나의 Aspect가 된다.

91 Weaving Advcie, Pointcut, Target Object로 분리된 것을 하나로 결합하는 것을 의미
Weaving 작업을 지원하는 Tool(AspectJ, Spring AOP)을 Weaver라 지칭

92 Advice

93 Advice 의 종류 Before advice : Join Point 전에 실행되는 Advice.
