SpringMVC数据格式转换报错：rejected value [065966] error in object 'command' on field 'imgNumber'
错误信息如下：
org.springframework.validation.BindException:
首先这个问题可以确定为是数据格式转换异常。问题出在BeanPropertyBindingResult，imgNumber是数据库表中的一个字段，有一个对应的bean，SpringMVC就是通过这个
javaBean来实现数据格式转换的。我们输入的字符串 “65966” ，在向后台传递的过程中，需要转化成整数，SpringMVC会根据十六进制，把我们输入的十进制的数字进行
转换。
解决方法一：统一数据格式，如果可以统一数据格式的话，最好统一数据格式，这样就不会进行数据格式的转换，就可以有效避免这种数据格式转换的错误；
解决方法二，不使用javaBean的方式传递数据，而是直接通过request对象的getParameter("imgNumber") 方法来接收页面传递过来的参数。
具体如何操作，还是要结合具体的项目来。

经过测试，当 imgNumber 输入下面的数值时，都会报错，当然，这些只是一部分，所有的情况不可能一一列举。

还有一点可以确定，就是，这个错误在进入后台controller方法之前就已经抛出了。
