// RestController 사용하기
1. TestController
package com.myspring.pro29.ex01;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.slf4j.Logger;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/test/*")
public class TestController {
static Logger logger = LoggerFactory.getLogger(TestController.class);
@RequestMapping("/hello")
public String hello() {
return "Hello REST!!";
}
@RequestMapping("/member")
public MemberVO member() {
MemberVO vo = new MemberVO();
vo.setId("hong");
vo.setPwd("1234");
vo.setName("홍길동");
vo.setEmail("hong@test.com");
return vo;
}
@RequestMapping("/membersList")
public List<MemberVO> listMembers () {
List<MemberVO> list = new ArrayList<MemberVO>();
for (int i = 0; i < 10; i++) {

}
return map;
}
@RequestMapping(value= "/notice/{num}" , method = RequestMethod.GET)
public int notice(@PathVariable("num") int num ) throws Exception {
return num;
}
@RequestMapping(value= "/info", method = RequestMethod.POST)
public void modify(@RequestBody MemberVO vo ){

}
// ResponseEntity 사용하기
@RequestMapping("/membersList2")

vo.setName("이순신" + i);
vo.setEmail("lee"+i+"@test.com");
list.add(vo);
}
return new ResponseEntity(list,HttpStatus.INTERNAL_SERVER_ERROR);
}
// ResponseEntity 사용하기
@RequestMapping(value = "/res3")
public ResponseEntity res3() {
HttpHeaders responseHeaders = new HttpHeaders();
responseHeaders.add("Content-Type", "text/html; charset=utf-8");
String message = "<script>";
message += " alert('새 회원을 등록합니다.');";
message += " location.href='/pro29/test/membersList2'; ";
message += " </script>";
return new ResponseEntity(message, responseHeaders, HttpStatus.CREATED);
}
}
2. MemberVO
package com.myspring.pro29.ex01;
public class MemberVO {
private String id;
private String pwd;
private String name;
private String email;
public MemberVO() {
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
String info = id+", "+ pwd+", "+ name+", "+ email;
return info;
}
}결과가 viewResolver로 안감
VO객체전달하기 : test/member
컬렉션객체전달하기 : test/membersList
Map 객체전달하기 : test/membersMap
PathVariable 사용하기 : test/notice/* : *에 들어간 값이 view로 리턴
