后台使用jfinal3.3，前台页面jsp+jquery3.2.1，项目部署在tomcat8.0下，使用localhost访问一切正常，但是使用127.0.0.1或者本机域名打开项目，查询数据库错误。
前台页面代码

},
error : function(data) {

后台java代码：
public class AreaOfferController extends Controller {
AreaOfferService aos = new AreaOfferService();
public void test() {
String level = getPara("level");
if (null == level || "".equals(level) || Integer.parseInt(level) == 0) {
setAttr("result", "0");
renderJson();
} else {
renderJson(aos.getAreaOffersByLevel(Integer.parseInt(level)));
}
}
