一个小疏忽，导致踩了半天的坑。。。。。
这是在由于实体类里面使用了@DecimalMax注解，然后在使用ValidatorUtils.validateEntity();进行参数验证的时候报的异常。
原因是有的字段在自动生成代码里面，value的值是空字符串，所以导致了题目所示的异常信息。
正确的使用方式如下：
@DecimalMax(value="9999999999999999999",message="主键值应小于9999999999999999999")

@ApiModelProperty(value="主键",example="填写例子")
@ApiParam(value="主键",defaultValue="填写例子")
private Long id;
看一下正常的使用方式，限制了最大值和最小值。
根据异常的提示：does not represent a valid BigDecimal format.以为是参数的格式异常了，然后看了一下@DecimalMax的源码:
这里也只提到需要是一个数字，最大值不能大于注解里面的value值。
然后想到是不是由于这个值超过了Long的最大值，然后打印一下Long的最大值，发现是9223372036854775807，19位数字，其中有的字段里面的value值是19个9，然后试着改成18位9，但是还是不行。
然后想着是不是因为加了这个注解之后，前台这个参数必须要穿一个数字型的字符串的值，就在准备一个一个字段的尝试时，突然发现，有的字段的value是空字符串，把value的值加上，重启，然后就好了。。。。。。。。。
