    本文主要解决用validator验证确认密码与密码是否相等的问题，对于validator原理和使用方法介绍不再讨论。

    1.配置消息文件 application.properties .

errors.equal = {0}  is not equal to  {1} .

    2.添加validation.xml代码.

<? xml version = " 1.0 "  encoding = " UTF-8 " ?>
<! DOCTYPE form - validation PUBLIC
      " -//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1.3//EN "
      " http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd " >
< form - validation >
     < formset >         
         < form name = " registerForm " >
             < field property = " username "  depends = " required,minlength " >
                 < arg0 key = " login.username " />
                 < arg1 name = " minlength "  key = " ${var:minlength} "  resource = " false " />
                 < var >
                     < var - name > minlength </ var - name >
                     < var - value > 5 </ var - value >
                 </ var >
             </ field >
             < field property = " password "  depends = " required,minlength " >
                 < arg0 key = " login.password " />
                 < arg1 name = " minlength "  key = " ${var:minlength} "  resource = " false " />
                 < var >
                     < var - name > minlength </ var - name >
                     < var - value > 5 </ var - value >
                 </ var >
             </ field >
             < field property = " repassword "  depends = " required,validwhen " >
                 < msg name = " validwhen "  key = " errors.equal " />
                 < arg0 key = " login.repassword " />
                 < arg1 name = " validwhen "  key = " login.password " />
                 < var >
                     < var - name > test </ var - name >
                     < var - value > (password ==* this * ) </ var - value >
                 </ var >
             </ field >
         </ form >
        
     </ formset >
</ form - validation >
