我想對我的操作類Employee1進行驗證。我使用了文件Employee1-validation.xml。我得到這樣一個例外：無法在struts2框架中加載驗證xml文件

在工程工作看起來像：
的Employee1.java樣子：
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
<field name="name">
<field-validator type="required">
<message>
The name is required.
</message>
</field-validator>
</field>
<field name="age">
<field-validator type="int">
<param name="min">29</param>
<param name="max">64</param>
<message>
Age must be in between 28 and 65
</message>
</field-validator>
</field>
</validators>
我收到這條線警告：
package com.struts2examples;
import com.opensymphony.xwork2.ActionSupport;
public class Employee1 extends ActionSupport{
private String name;
private int age;
public String execute()
{
return SUCCESS;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
的Employee1-validation.xml文件在同一package.It描述如下：
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
的文件不能被驗證爲XML定義「http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd」，也就是指定 作爲描述SY無法找到文件的ntax。
