Jsp中判断该登录用户是否是作者然后显示不同的菜单选项

1.//后台代码

@Namespace("/www")
@ResultPath("/WEB-INF")
@SuppressWarnings("serial")
public class WwwUserUtilsAction extends ActionSupport {
@Autowired
private OriginalAuthorManager originalAuthorManager;
private boolean isAuthor = false; 
private String parentNav;
private String sonNav;
	
public String getSonNav() {
  return sonNav;
}
public void setSonNav(String sonNav) {
   this.sonNav = sonNav;
}
public String getParentNav() {
   return parentNav;
}
public void setParentNav(String parentNav) {
this.parentNav = parentNav;
}

public void author(){
Integer userId=RequestContext.getCurrUser().getId().intValue();
if(userId.intValue()!=0){
 //判断该用户是否作家
OriginalAuthor entity = new OriginalAuthor();
entity.setUserId(userId);
List<OriginalAuthor> list =originalAuthorManager.getByEntity(entity);
if(list!=null && list.size()>0){
		isAuthor = true;
			}
		}
	Struts2Utils.renderText(""+isAuthor);
     }
}
2.对应的jsp代码
