Answer 1

可能是楼主没有给Validator配置message。

Answer 2

我給了一個 UserinfoAction.properties文件，內容如下：userinfo=Userinfo
userinfo.userName.required=\u8bf7\u8f93\u5165\u4e66\u540d
format.date={0,date,yyyy-MM-dd}
其實我的例子很簡單的，就一張表，里面兩個字段id,userName,就是在一個頁面里想驗證下 userName,頁面主要內容如下：
<s:form name="editForm" action="save" validate="true">
     <s:textfield label="用戶名" name="userinfo.userName"></s:textfield>
 <s:submit value="保存" />
</s:form>

Answer 3

對了，還有一個文件 UserinfoAction-save-validation.xml 內容如下：<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.dtd">
<validators>
    <!-- Field-Validator Syntax -->
    
    <field name="userinfo.userName">
        <field-validator type="requiredstring">
            <message key="userinfo.userName.required"/>
        </field-validator>
    </field>
   
</validators>請各位幫忙，多謝了

Answer 4

提示RequiredStringValidator有问题
把UserinfoAction-save-validation.xml 改成UserinfoAction-validation.xml试试，是不是命名问题啊

Answer 5

把form里validate属性的值设为false就不会报错了
