关于springMVC中:Failed to convert property value of type 'java.lang.String' to required type 'java.util

关于SpringMVC+mybatis中提交出现的错误:

Field error in object 'customer' on field 'dcreatedate': rejected value []; codes [typeMismatch.customer.dcreatedate,typeMismatch.dcreatedate,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [customer.dcreatedate,dcreatedate]; arguments []; default message [dcreatedate]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'dcreatedate'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type java.lang.String to type java.util.Date for value ''; nested exception is java.lang.IllegalArgumentException]

出错背景:

entity及属性:

Customer

private Date dcreatedate;

jsp及JS:

$.ajax({
		type: "POST",
		url: ****,
    	data: params,
		dataType:'json',
		cache: false,
		success: function(data){
			//加载页面数据
			setTablePageData(data);
			//保存查询条件
			$("#myFilterParams").val(JSON.stringify(params));
		}
	});
Controller:

@RequestMapping(value="findByPage", method=RequestMethod.POST)
@ResponseBody
public AjaxRes findByPage(Page page,Customer o){
}

提交的时候报上面的错误,网上找了好多资,包括配置Controller注解:@InitBinder;最后发现,把实体属性dcreatedate修改为:dCreateDate,就不报错了,似乎全小写就报错。

(⊙﹏⊙),真不知道是什么原因,如果哪位知道,希望留个言告知下。
