validator 自定义验证规则

1. 定义自己的验证方法类：

java 代码

java 代码

1.  public static boolean validateTwoFields(Object bean, ValidatorAction va,   
2.                                             Field field, ActionMessages errors,   
3.                                             HttpServletRequest request) {   
4.         String value =   
5.            ValidatorUtils.getValueAsString(bean, field.getProperty());//得到用户输入的该filed的值   
6.         String sProperty2 = field.getVarValue("secondProperty"); //得到定义在field的变量(validation.xml中),此处指定的是另一个field name   
7.         String value2 = ValidatorUtils.getValueAsString(bean, sProperty2);   
8.   
9.         if (!GenericValidator.isBlankOrNull(value)) {   
10.             try {   
11.                 if (!value.equals(value2)) {   
12.                     errors.add(field.getKey(),   
13.                                Resources.getActionMessage(request, va, field));   
14.   
15.                     return false;   
16.                 }   
17.             } catch (Exception e) {   
18.                 errors.add(field.getKey(),   
19.                            Resources.getActionMessage(request, va, field));   
20.   
21.                 return false;   
22.             }   
23.         }   
24.   
25.         return true;   
26.     }   
27. }   

 2  .到validator-rule-custom.xml加入你定制的rule.

xml 代码

1. <field property="password"  
2.                    depends="required,twofields">  
3.                 <msg  
4.                   name="twofields"  
5.                   key="errors.twofields"/>  
6.   
7.                 <arg0 key="userForm.password"/>  
8.                 <arg1  
9.                   key="userForm.confirmPassword"  
10.                 />  
11.                 <var>  
12.                   <var-name>secondPropertyvar-name>  
13.                   <var-value>confirmPasswordvar-value>  
14.                 var>  
15.             field>  
16.             <field property="confirmPassword"  
17.                    depends="required">  
18.   
19.                 <arg0 key="userForm.confirmPassword"/>  
20.             field>
