package com.springmvc.chap05;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class Example01Controller {

}
}package com.springmvc.chap05;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class Example02Controller {
@RequestMapping(value="/exam02", method=RequestMethod.GET)
public void requestMethod()
{
System.out.println("exam2입니다.");
}
}
@RequestMapping을 이용한 요청 매핑 경로 설정
컨트롤러에 @RequestMapping 적용
BookController.java 수정.
package com.springmvc.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.springmvc.domain.Book;
import com.springmvc.service.BookService;
@Controller
@RequestMapping("books") //추가
public class BookController {
//autowired 자동으로 변수에 대입을 해준다. 라고 생각
@Autowired
private BookService bookService;
//매핑에서 value값을 찾아서 반환해준다.
@RequestMapping //수정
public String requestBookList(Model model)
{
List<Book> list = bookService.getAllBookList();
model.addAttribute("bookList", list);
return "books";
}
@RequestMapping("/all") //수정
public String requestAllBooks(Model model)
{
List<Book> list = bookService.getAllBookList();
model.addAttribute("bookList", list);
return "books";
}
}메서드 수준의 @RequestMapping 단순화
porm.xml 에서 버전을 변경 후
BookControler.java 변경
package com.springmvc.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import com.springmvc.domain.Book;
import com.springmvc.service.BookService;
@Controller
@RequestMapping("books") //추가
public class BookController {
//autowired 자동으로 변수에 대입을 해준다. 라고 생각
@Autowired
private BookService bookService;
//매핑에서 value값을 찾아서 반환해준다.
@GetMapping //수정
public String requestBookList(Model model)
{
List<Book> list = bookService.getAllBookList();
model.addAttribute("bookList", list);
return "books";
}
@GetMapping("/all") //수정
public String requestAllBooks(Model model)
{
List<Book> list = bookService.getAllBookList();
model.addAttribute("bookList", list);
return "books";
}
}
