全局———>自定义类型转换器------------------->
<---------------------------------------------------------->
<---------------------------------------------------------->
<---Date时间自定义转换器，用两步就可以将时间的类型进行转换。
全局类型转换器，必须在类里面的Date的时间方法都是19920912或者
1992-09-12或者
1992/09/12在统一的情况下才能用全局类型转换，或者会出现错误。建议
在Date不确定
的情况下最好是用局部转换器。---><---------------------------------------------------------->
