Controller JSP
,
....

7. Model1
• Model 1

• :
1. :
2. : Controller JSP

12. DispatcherServlet
1. DispatcherServlet HTTP request
Spring MVC framework
2. Web layer Spring
Container(WebApplicationContext), BO
layer Spring Container(ApplicationContext)
Web layer bean BO layer bean ?
3. initial Spring MVC Component,
DispatcherServlet ?

13. 1. DispatcherServlet HTTP request
Spring MVC framework
/WEB-INF/servlet-name-servlet.xml
Web layer Spring Container

14. Web layer Spring Container(WebApplicationContext),
BO layer Spring Container(ApplicationContext)
Web layer bean BO layer bean ?

15. Web Layer Spring Container
BO Layer Spring ContainerBO Layer Spring ContainerBO Layer Spring ContainerBO Layer Spring ContainerBO Layer Spring Container
Children Container
Parent Container
BO Layer can not call Web Layer
Web Layer can call BO Layer

16. DispatcherServlet
• namespace: ftc, Spring
WEB-INF/ftc.xml
• contextConfigLocation: Spring
”classpath:ftc1.xml, classpath:ftc2.xml“ initial
WebApplicationContext
• publishContext: boolean DispatcherServlet
WebApplicationContext ServletContext
ServletContext WebApplicationContext Instance
• publishEvents:boolean DispatcherServlet request
Container ServletRequestHandlerEvent, true,

18. Annotation driven controller
• @RequestMapping
• @Controller
• @PathVariable
• @RequestParam
• @CookieValue
• @RequestHeader

19. User Request

20. @RequestMapping
• POJO @Controller
• <context:component-scan/> package
POJO HTTP request controller
• controller controller
method request
• request controller
@RequestMapping

21. • Controller
class @RequestMapping

22. @RequestMapping URL

• Map Model: return Map
• @SessionAttributes:
HttpSession

36. ModelAndView

37. @ModelAttribute

41. • Spring MVC Model
• @ModelAttribute return add Model
• Session @SessionAttributes(“xxx”) xxx
xxx Model
• @ModelAttribute(“xxx”)
1. Model xxx
2. xxx session Class @SessionAttributes(“xxx”)
HttpSesionRequiredException
3. Model xxx session request

43. org.springframework.validation

44. LocalValidtorFactoryBean
• Spring Validator interface
• JSR 303 Validator interface
