controller & jsp

1. 고객목록화면

1) controller

@Controller public class CustomerListController { @Autowired private CustomerService customerService; @RequestMapping(value="/customer", method= GET) public String showAllCustomers(Model model){ List<Customer>customers = customerService.findAll(); model.addAttribute("customers",customers); return "customer/list"; } @RequestMapping(value="/", method=GET) public String home(){ return "forward:/customer"; } }

- 컨텍스트 루트(/)로 엑세스 했을 시 /customer에 포워딩 되도록 변경함

2) jsp

<%@ page language="java" contentType="text/html; charset=EUC-KR" pageEncoding="EUC-KR"%> <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <head> <meta http-equiv="Content-Type" content="text/html; charset=EUC-KR"> <title>Insert title here</title> </head> <h2>Client list</h2> <table border="1"> <tr> <th>Id</th> <th>name</th> <th>address</th> <th>email</th> <td></td> </tr> <c:forEach items="${customers}" var="customer"> <tr> <td><c:out value="${customer.id}"/></td> <td><c:out value="${customer.name}"/></td> <td><c:out value="${customer.address}"/></td> <td><c:out value="${customer.email}"/></td> <td> <c:url value="/customer/${customer.id }" var="url"/> <a href="${url }">detail</a> <c:url value="/customer/${customer.id }/edit" var="url"/> <a href="${url }">modify</a> </td> </tr> </c:forEach> </table>

- View와 뷰리졸버의 설명처럼 Model 오브젝트로 설정한 오브젝트는 스프링MVC가 자동으로 HttpServeltRequest로 설정

2. 고객정보화면표시처리

1) Controller

@RequestMapping(value="/customer/{customer}",method= GET) public String showCustomerDetail(@PathVariable int customerId,Model model) throws DataNotFoundException{ Customer customer = customerService.findById(customerId); model.addAttribute("customer",customer); return "customer/detail"; }

2) jsp

<%@ page language="java" contentType="text/html; charset=EUC-KR" pageEncoding="EUC-KR"%> <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <head> <meta http-equiv="Content-Type" content="text/html; charset=EUC-KR"> <title>Insert title here</title> </head> <h1>Client info</h1> <dl> <dt>name</dt> <dd><c:out value="${customer.name }"/></dd> <dt>address</dt> <dd><c:out value="${customer.address }"/></dd> <dt>email</dt> <dd><c:out value="${customer.email }"/></dd> </dl> <c:url value="/customer"var="url"/> <a href="${url }">list</a>
