今天改一个页面，点击跳转运行报错，代码改动很小，不应该会报错

---------------------------------------------------错误日志--------------------------------------------------------------

最后找了一圈日志中提示对应的错误行数，才发现自己少写了一个赋值。

笨的一匹。

------------------------------------------------------------------------------------------------------------------------------
^(\\d{6})(18|19|20)?(\\d{2})((0[1-9])|(1[0-2]))(([0|1|2][1-9])|(3[0-1]))(\\d{3})(\\d|X){1}$
这个是身份证的正则验证表达式，这个正则可以不让111111111111.。。。的数据过去。

------------------------------------------------------------------------------------------------------------------------------
target is null for setProperty(null, "gmsfzh", [Ljava.lang.String;@51a7f9)
多方百度发现是对象忘了给他实例化
comeoutinfo comeoutinfo = new comeoutinfo();

PS：以后如果在遇到这种小问题，会持续更新ing
