Java Web 求助。帮看看这个验证方法哪里出错了？只有四个不填的时候才正确跳转，别的都是提示成功？？？

用正则表达式。String类中的matches（）；
if((email!="")||(email==regExpression)||(mobileNo==regExpression1)||(mobileNo!="")||(IDCard==regIDCard_18)||(IDCard!="")||(realName==regExpression2)||(realName!=""))
改成
if((email!="")&& email.matches(regExpression)&& mobileNo.matches(regExpression1)&& mobileNo!="" && IDCard.matches(regIDCard_18) && (IDCard!="") && realName.matches(regExpression2)&& (realName!="")){
还有把正则表达式的匹配串中的开始和结束的‘/’去掉
if((email!="")||(email==regExpression)||(mobileNo==regExpression1)||(mobileNo!="")||(IDCard==regIDCard_18)||(IDCard!="")||(realName==regExpression2)||(realName!=""))
改成
if((email!="")&& email.matches(regExpression)&& mobileNo.matches(regExpression1)&& mobileNo!="" && IDCard.matches(regIDCard_18) && (IDCard!="") && realName.matches(regExpression2)&& (realName!="")){

这里明显应该用&&吧，你注册的要求是满足其中某一个条件就够了？
另外，你的操作都在servlet里进行啊？这应该放在页面上用JS来判断...

追问
要全部都满足才能提示注册成功。servlet是一个控制器，判断的语句已经在JSP里实现了。问题就出在servlet。但是就不是不知道怎么改

改成
if((email!="")&&(email==regExpression)&&(mobileNo==regExpression1)&&(mobileNo!="")&&(IDCard==regIDCard_18)&&(IDCard!="")&&(realName==regExpression2)&&(realName!="")){
