BeanUtils.copyProperties拷贝form到实体bean时出错
form属性：
 private String innerId;
 private TbCar tbCar = new TbCar();
 private TbCustomer tbCustomer = new TbCustomer();
 private String zhixing;
 private String zulinPrice = "0";
 private String yajin = "0";
 private String preZujin = "0";
 private String zulinQixian = "0";
 private String chaoshiFee = "0";
 private String lichengMeitian = "0";
 private String outTimeFee = "0";
 private String jingbanren;
 private String yudingDate;
 private String yudingTime;
 private String demo;
bean属性：
 private String innerId;
 private TbCar tbCar = new TbCar();
 private TbCustomer tbCustomer = new TbCustomer();
 private String zhixing;
 private Integer zulinPrice;
 private Integer yajin;
 private Integer preZujin;
 private Integer zulinQixian;
 private Integer chaoshiFee;
 private Integer lichengMeitian;
 private Integer outTimeFee;
 private String jingbanren;
 private Date yudingDate;
 private Time yudingTime;
 private String demo;
异常：java.lang.IllegalArgumentException: argument type mismatch。
问题补充：据自己推测应该是复制TbCar和TbCustomer时类型不匹配照成的。请大家帮帮忙。

------解决方案--------------------
如果源是String，目标对象是Integer。匹配难度是很小的。只要check正确也没有问题
如果源是String，目标对象是java.util.Date。你说怎么匹配？就算匹配了，风险也太大了。

这篇文章你可以读下，但是我不推荐你这么做。
