解决办法是:一是升级 jfinal 到最新版本, 二是将最后一个参数强制转化成 Object,或引入一个中间变量。
如果不想升级 jfinal 解决办法如下:
Db.findById("provinceinfo", "provinceinfo_id", (Object)record.getInt("provinceinfo_id"));
或者:
Object para = record.getInt("provinceinfo_id");
Db.findById("provinceinfo", "provinceinfo_id", para);
这个问题是由 JDK 8 引发的与 jfinal 无关。而 jfinal 新版本通过调整 findByIds 解决了这个问题
