[Spring] 컨트롤러 액션에서 외부 URL로 redirection

컨트롤에서 리다이렉션을 시키는 방법을 포스팅해 보았습니다.

 

package com.peterica.swagger.controller;

import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.view.RedirectView;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

@Controller
public class RedirectController {

    // return string
    @GetMapping("/ex_redirect1")
    public String exRedirect1() {
        return "redirect:http://www.naver.com";
    }

    // httpHeaders
    @RequestMapping("/ex_redirect2")
    public ResponseEntity<Object> exRedirect2() throws URISyntaxException {
        URI redirectUri = new URI("http://www.naver.com");
        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.setLocation(redirectUri);
        return new ResponseEntity<>(httpHeaders, HttpStatus.SEE_OTHER);
    }

    // httpServletResponse.sendRedirect
    @GetMapping("/ex_redirect3")
    public void exRedirect3(HttpServletResponse httpServletResponse) throws IOException {
        httpServletResponse.sendRedirect("https://naver.com");
    }

    // RedirectView
    @RequestMapping("/ex_redirect4")
    public RedirectView exRedirect4() {
        RedirectView redirectView = new RedirectView();
        redirectView.setUrl("http://www.naver.com");
        return redirectView;
    }

}
