I'm relying on JAXB to generate the sitemap.xml for me.
我依靠 JAXB 为我生成 sitemap.xml。
My controller looks something like the below, and I have some database tables to keep track of the links that I want to appear in the sitemap:-
我的控制器看起来像下面这样，我有一些数据库表来跟踪我想要出现在站点地图中的链接：-
SitemapController.java
站点地图控制器.java
@Controller
public class SitemapController {
@RequestMapping(value = "/sitemap.xml", method = RequestMethod.GET)
@ResponseBody
public XmlUrlSet main() {
XmlUrlSet xmlUrlSet = new XmlUrlSet();
create(xmlUrlSet, "", XmlUrl.Priority.HIGH);
create(xmlUrlSet, "/link-1", XmlUrl.Priority.HIGH);
create(xmlUrlSet, "/link-2", XmlUrl.Priority.MEDIUM);
// for loop to generate all the links by querying against database
...
return xmlUrlSet;
}
private void create(XmlUrlSet xmlUrlSet, String link, XmlUrl.Priority priority) {
xmlUrlSet.addUrl(new XmlUrl("http://www.mysite.com" + link, priority));
}
}
XmlUrl.java
XmlUrl.java
@XmlAccessorType(value = XmlAccessType.NONE)
@XmlRootElement(name = "url")
public class XmlUrl {
public enum Priority {
HIGH("1.0"), MEDIUM("0.5");
private String value;
Priority(String value) {
this.value = value;
}
public String getValue() {
return value;
}
}
@XmlElement
private String loc;
@XmlElement
private String lastmod = new DateTime().toString(DateTimeFormat.forPattern("yyyy-MM-dd"));
@XmlElement
private String changefreq = "daily";
@XmlElement
private String priority;
public XmlUrl() {
}
public XmlUrl(String loc, Priority priority) {
this.loc = loc;
this.priority = priority.getValue();
}
public String getLoc() {
return loc;
}
public String getPriority() {
return priority;
}
public String getChangefreq() {
return changefreq;
}
public String getLastmod() {
return lastmod;
}
}
XmlUrlSet.java
XmlUrlSet.java
@XmlAccessorType(value = XmlAccessType.NONE)
@XmlRootElement(name = "urlset", namespace = "http://www.sitemaps.org/schemas/sitemap/0.9")
public class XmlUrlSet {
@XmlElements({@XmlElement(name = "url", type = XmlUrl.class)})
private Collection<XmlUrl> xmlUrls = new ArrayList<XmlUrl>();
public void addUrl(XmlUrl xmlUrl) {
xmlUrls.add(xmlUrl);
}
public Collection<XmlUrl> getXmlUrls() {
return xmlUrls;
}
}
For the robots.txt, it looks something like the below, and obviously, you will need to configure it based on your likings:-
对于robots.txt，它看起来像下面这样，显然，您需要根据自己的喜好配置它：-
RobotsController.java
机器人控制器.java
@Controller
public class RobotsController {
@RequestMapping(value = "/robots.txt", method = RequestMethod.GET)
public String getRobots(HttpServletRequest request) {
return (Arrays.asList("mysite.com", "www.mysite.com").contains(request.getServerName())) ?
"robotsAllowed" : "robotsDisallowed";
}
}

Add this line to your dispatcher servlet xml file:
将此行添加到您的调度程序 servlet xml 文件中：
<mvc:resources mapping="/robots.txt" location="/WEB-INF/robots.txt" order="0"/>
Put the robots.txt at WEB-INF/robots.txt. The file will be accessible by yoursite.com/robots.txt
将 robots.txt 放在 WEB-INF/robots.txt 中。该文件可通过 yoursite.com/robots.txt 访问
