问题是当我尝试通过 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。

我在这里发布我的代码，

注册.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>

struts.xml

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

InsertAction.java(动作类)

public class InsertAction {
    private String username,password,cpassword,emailid;
    private int mobileno;
    private Date dob;   
    DAO dao=new DAO();
    public String execute(){
        return "success";
    else
        return "error";
    }

InsertAction-validation.xml

      <message>Year should be With in ${min} and ${max}</message>
    </field-validator>
  </field>
</validators>

不缩进代码和 XML 是一个可怕的想法；这是不可能的考虑。

错误信息：

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

所以。第 30 行附近有什么<param>元素吗？

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

哦，看，那个元素没有name属性。<param>

此外，您的execute()方法是可疑的，不清楚您的操作属性是否有公共设置器。
