BunkNo这个字段在数据库表里是number(4,0)，我用的是oracle数据库，另外

还有不止int BunkNo这个字段出现这个问题，还有Amount，Weight，WorkNo都出过同样的问题，Amount在数据库表里是number(19,0)，Weight在数据库表里是number(19,3)，WorkNo在数据库表里是Varchar2(10)，amount在java里也是int型，倒是可以改成integer了，但weight在java里是double型，workNo是string型呀，那怎么办？究竟怎么回事会发生这种错误呢？

double 改成 Double 你要把数据库字段的格式与类属性格式改成一致

可是oralce里数字都是用number表示的，我怎么一致？还有workNo是string型，怎么办？

number不就是整数workNo就换成数字啊
