维帝博客 - SpringBoot 做 sitemap.xml # 基于Xstream方式返回xml

直接先看效果：https://veddy.cn/sitemap.xml

下面看实现的代码：

1、在maven的pom.xml配置文件中增加maven依赖：

```
<dependency>
    <groupId>com.thoughtworks.xstream</groupId>
    <artifactId>xstream</artifactId>
    <version>1.4.11.1</version>
</dependency>
```

2、编写代码：

```java
import com.thoughtworks.xstream.annotations.XStreamAlias;

@XStreamAlias("url")
public class Url {
    private String loc;
    private String lastmod;
    private String changefreq;
    private String priority;

public String getLoc() {
        return loc;
    }

public void setLoc(String loc) {
        this.loc = loc;
    }

public String getLastmod() {
        return lastmod;
    }

public void setLastmod(String 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;
    }
}
```

```java
@RequestMapping(value = "/sitemap",produces = {"application/xml;charset=UTF-8"},method = RequestMethod.GET)
    @ResponseBody
    public String sitemap(){
        String lastmod = DateFormatUtils.getDefaultFormatDate(new Date(),"yyyy-MM-dd");
        List<Url> urls = new ArrayList<>();
        Url url = new Url();
        url.setLoc(sitemapurl);
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("1.00");
        urls.add(url);

url = new Url();
        url.setLoc(sitemapurl + "/minapp.html");
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("0.5");
        urls.add(url);

url = new Url();
        url.setLoc(sitemapurl + "/blogs/1.html");
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("0.5");
        urls.add(url);

url = new Url();
        url.setLoc(sitemapurl + "/page/personTax.html");
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("0.5");
        urls.add(url);

url = new Url();
        url.setLoc(sitemapurl + "/page/personSafe.html");
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("0.5");
        urls.add(url);

url = new Url();
        url.setLoc(sitemapurl + "/page/personHouse.html");
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("0.5");
        urls.add(url);

url = new Url();
        url.setLoc(sitemapurl + "/page/personCar.html");
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("0.5");
        urls.add(url);

url = new Url();
        url.setLoc(sitemapurl + "/minapp/detail/10000.html");
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("0.25");
        urls.add(url);

url = new Url();
        url.setLoc(sitemapurl + "/minapp/detail/10001.html");
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("0.25");
        urls.add(url);

url = new Url();
        url.setLoc(sitemapurl + "/blog/detail/100000.html");
        url.setLastmod(lastmod);
        url.setChangefreq(Changefreq);
        url.setPriority("0.25");
        urls.add(url);
        XStream xstream = new XStream(new StaxDriver());
        xstream.alias("url",Url.class);
        xstream.alias("urlset",List.class);
        return xstream.toXML(urls);
    }
```

下面展示一下在线转换好的效果

```xml
<urlset>
<url>
<loc>https://veddy.cn/article/31</loc>
<lastmod>2020-04-10</lastmod>
<changefreq>hourly</changefreq>
<priority>1.0</priority>
</url>
<url>
<loc>https://veddy.cn/article/30</loc>
<lastmod>2020-04-10</lastmod>
<changefreq>hourly</changefreq>
<priority>0.9</priority>
</url>
</urlset>
```
