SpringMVC [출처] SpringMVC 환경설정 (비공개 카페)

여태까지는 Servlet / JSP배우면서 Model2 MVC를 흉내내거나

spring넘어와서도 Java Project 생성 후 Model2 MVC를 흉내내는 수준의 작업이였다.

• 환경설정 및 개발단계

1. spring library 를 maven으로 추가  

2. log4j 설정파일확인 (선택적)

3. web.xml에서 

    springframework의 DispatcherServlet 설정 추가 

    ( servlet-name 과 servlet-class , url-pattern ) 

    [servlet name]-servlet.xml 로 springmvc framework 설정

    파일을 기본적을 찾게 된다. 

 4. url-pattern 을 *.do 형태로 지정하여 

  .do로 마치는 모든 요청을 spring의 DispatcherServlet이 처리

  하도록 설정한다. 

5. springmvc 설정파일 

 1) HandlerMapping 등록 

 2) ViewResolver 등록 

 3) 사용될 컨트롤러를 등록

이동할 URL을 *.do로 설정하여 끝나는 부분이 do인 url을 걸러낸다

* web.xml * <servlet>     <servlet-name>dispatcher</servlet-name>     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping>     <servlet-name>dispatcher</servlet-name>     <url-pattern>*.do</url-pattern> </servlet-mapping> Colored by Color Scripter

.do로 들어온 url을 CustomerController로 보낸다

* dispatcher-servlet.xml * <?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.xsd"> HandlerMapping 등록 <bean id="handlerMapping"  class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean> viewResolver 등록 <bean id="viewResolver"  class="org.springframework.web.servlet.view.InternalResourceViewResolver">     <property name="prefix" value="/views/" />     <property name="suffix" value=".jsp"/> </bean> <bean id="methodNameResolver"  class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">     <property name="paramName" value="command"/> </bean> <bean id="customerDAO" class="model.CustomerDAOImpl"> </bean> <bean id="customerService" class="model.CustomerServiceImpl">     <constructor-arg ref="customerDAO"/> </bean> 사용될 컨트롤러를 등록  <bean id="/customer.do" class="controller.CustomerController">     <constructor-arg ref="customerService"/>     <property name="methodNameResolver"  ref="methodNameResolver"/> </bean> </beans> Colored by Color Scripter

위처럼 xml을 설정한 후 id를 검색한다.

* index.jsp * <form action = "customer.do"> <input type = "hidden" name = "command" value = "findCustomerById"> 아이디 <input type = "text" name = "id">          <input type = "submit" value = "검색"> </form> Colored by Color Scripter

Controller -> Service -> DAO -> Controller -> View로 진행된다

* STEP1 -> find_ok.jsp or find_fail.jsp * public class CustomerController extends MultiActionController {     private CustomerService customerService;     public CustomerController(CustomerService customerService) {         super();         this.customerService = customerService;     }     public ModelAndView findCustomerById     (HttpServletRequest request, HttpServletResponse response) {         String id = request.getParameter("id");         CustomerVO cvo = customerService.findCustomerById(id);         if (cvo == null)             return new ModelAndView("find_fail");         else             return new ModelAndView("find_ok", "cvo", cvo);     } } * STEP2 * public class CustomerServiceImpl implements CustomerService {     private CustomerDAO customerDAO;         public CustomerServiceImpl(CustomerDAO customerDAO) {         super();         this.customerDAO = customerDAO;     }     @Override     public CustomerVO findCustomerById(String id){         return customerDAO.findCustomerById(id);     } } * STEP3 -> STEP1 * (DB없이 test) public class CustomerDAOImpl implements CustomerDAO {     @Override     public CustomerVO findCustomerById(String id) {         CustomerVO vo = null;         if (id.equals("java"))             vo = new CustomerVO(id, "손재만", "판교");         return vo;     } } Colored by Color Scripter

아직도 XML 사용방법에 대해서는 어리둥절하고 있지만
확실히 springMVC 구조가 잡히는게 눈에 보이고있다.
