Question

问题是当我尝试通过struts验证验证字段时。它起作用....我可以在tomcat上看到错误消息。

我在这里发布我的代码，

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>

struts.xml中

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

InsertAction.java（Action Class）

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中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators

      <message>Mobile No Must be ${minLength} Digit..</message>
    </field-validator>
  </field>

  <field name="dob">
    <field-validator type="date">
      <param name="min">2000/01/1</param>
      <param name="max">2013/09/1</param>

    </field-validator>
  </field>
</validators>

Answer 1

不缩进代码和XML是一个可怕的想法;这是不可能的。

错误消息：

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

因此。你在第30行附近有<param>个元素吗？

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

哦，看，name元素没有<param>属性。

此外，您的execute()方法存在疑问，并且您是否拥有针对您的操作属性的公共设置器尚不清楚。
