使用JFinal是报错：com.jfinal.plugin.activerecord.ActiveRecordException: java.sql.SQLException: Error

具体如下：

仔细看下出错代码，可以看到在：Caused by: java.lang.AssertionError处，有个报错：setObject。

初步怀疑是，record.set 的时候有问题。排查了下代码，发现我是这样赋值的：

record.set("SpellCode", row.getCell(4));

row.getCell 返回的是 Cell 类型，简单的处理下：

record.set("SpellCode", row.getCell(4).toString());

就不报错了。
