在struts2中验证工作不正常

问题是当我试图通过struts验证来验证字段时。它不起作用。。。。我可以在tomcat上看到错误消息

我把代码贴在这里

Register.jsp

  <s:form action="insertdata">
  <s:textfield name="username" key="label.uname" required="true"/>
  <s:password name="password" key="label.pass" required="true"/>
  <s:password name="cpassword" key="label.cpass" required="true"/>
  <s:textfield name="emailid" key="label.mail" required="true"/>
  <s:textfield name="mobileno" key="label.mobileno" required="true"/>
  <s:datetimepicker name="dob" key="label.dob" displayFormat="MM/dd/yy" required="true"/>
  <s:submit value="Register"/>
</s:form>

插入操作验证.xml

<action name="insertdata" class="com.curd.action.InsertAction">
  <result name="success">RegisterSuccessful.jsp</result>
  <result name="error">NotRegister.jsp</result>
</action>

不缩进代码和XML是一个可怕的想法；这是无法想象的

错误消息：

SEVERE: Attribute "name" is required and must be specified for element type "param".

所以。第30行附近是否有

元素

<param minLength="10"></param>

哦，看，这个

元素没有

名称

属性

---

另外，您的

execute（）

方法是可疑的，并且不清楚您的操作属性是否有公共设置器。

可能存在重复的insertdata表单的字段名称在InsertAction验证中可能不相同。xml“另外，您的execute（）方法是可疑的”：我大声笑道：D

SEVERE: Attribute "name" is required and must be specified for element type "param".

<param minLength="10"></param>
