Spring Boot - Sitemap xml 생성하기

SpringBoot 에서 RestController 호출로 사이트맵을 생성해 리턴하려고 합니다.

사용방법은 간단합니다.

사이트맵 규칙에 맞춰 xml을 생성하고, String으로 Response 해주면 끝이지요!

아래 예제를 보시고 한번 따라해보세요!

1. SiteMapController.java 생성

@RestController
public class SiteMapController {
	@Autowired
	private SiteMapService siteMapService;
	@RequestMapping(value="/sitemap.xml", produces= {"application/xml"})
	@ResponseBody
	public ResponseEntity<String> sitemap (HttpServletRequest request, HttpServletResponse response) throws UnsupportedEncodingException{
		return ResponseEntity.ok(siteMapService.getSystemicSiteMap());
	}
}

2. SiteMapService.java 생성

@Service
public class SiteMapService {
    public static final String BASE_URL = "http://www.site.com";
    public static final String BEGIN_DOC = "<urlset xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\">";
    public static final String END_DOC = "</urlset>";
    public static final String CHANGEFREQ_ALWAYS = "always";
    public static final String CHANGEFREQ_HOURLY = "hourly";
    public static final String CHANGEFREQ_DAILY = "daily";
    public static final String CHANGEFREQ_WEEKLY = "weekly";
    public static final String CHANGEFREQ_MONTHLY = "monthly";
    public static final String CHANGEFREQ_YEARLY = "yearly";
    public static final String CHANGEFREQ_NEVER = "never";
    
    public String getSystemicSiteMap() throws UnsupportedEncodingException {
    	Date now = new Date();
    	StringBuffer sb = new StringBuffer();
        sb.append(BEGIN_DOC);
        sb.append(new SiteMap(BASE_URL, now, CHANGEFREQ_NEVER, "1.0"));
        return sb.toString();
    }
}

3. Sitemap.java 생성

public class SiteMap {
	private static final SimpleDateFormat SITE_MAP_DATE_FORMAT = new SimpleDateFormat("yyyy-MM-dd");
    public SiteMap(String loc) {
        this.loc = loc;
        this.lastmod = new Date();
        this.changefreq = SiteMapService.CHANGEFREQ_NEVER;
        this.priority = "1.0";
    }
    public SiteMap(String loc, Date lastmod, String changefreq, String priority) {
        this.loc = loc;
        this.lastmod = lastmod;
        this.changefreq = changefreq;
        this.priority = priority;
    }
    /**
     * url
     */
    private String loc;
    /**
     * yyyy-MM-dd
     */
    private Date lastmod;
    /**
     * always hourly daily weekly monthly yearly never
     */
    private String changefreq;
    /**
     * 1.0 0.9 0.8
     */
    private String priority;
    public String getLoc() {
        return loc;
    }
    public void setLoc(String loc) {
        this.loc = loc;
    }
    public Date getLastmod() {
        return lastmod;
    }
    public void setLastmod(Date lastmod) {
        this.lastmod = lastmod;
    }
    public String getChangefreq() {
        return changefreq;
    }
    public void setChangefreq(String changefreq) {
        this.changefreq = changefreq;
    }
    public String getPriority() {
        return priority;
    }
    public void setPriority(String priority) {
        this.priority = priority;
    }
    @Override
    public String toString() {
        StringBuffer sb = new StringBuffer();
        sb.append("<url>");
        sb.append("<loc>" + loc + "</loc>");
        sb.append("<lastmod>" + SITE_MAP_DATE_FORMAT.format(lastmod) + "</lastmod>");
        sb.append("<changefreq>" + changefreq + "</changefreq>");
        sb.append("<priority>" + priority + "</priority>");
        sb.append("</url>");
        return sb.toString();
    }
}
