}构造实体类，通过freemarker将实体类的信息渲染至html
@GetMapping("test")

list.add(new Poem("事了拂衣去，", "深藏身与名。"));
map.put("author","李白");
map.put("poem",list);
FreeMarkerUtil.createHtml("poem.ftl","poem.html","侠客行/","侠客行/",map);
return BackMessage.ok(map);
}实体类：
@Data
public class Poem {
private String first;
private String second;
public Poem(String first, String second) {
this.first = first;
this.second = second;
}
