Question

struts1.1中validate()不起作用，为什么？

HelloForm继承ACTIONFORM，重写validate()如下：
public ActionErrors validate(ActionMapping mapping, ServletRequest request) {
// TODO Auto-generated method stub
ActionErrors errors=new ActionErrors();
System.out.println("进入到formbean");
if(this.userName.isEmpty()||this.userName.equals("aaa")){
errors.add("p2", new ActionError("hello.nousername.error"));
}
return errors;
}
--------------------------------------
-------------------------------------<br>
<form-beans>
<form-bean name="HelloForm" type="hp.HelloForm"></form-bean>
</form-beans>

<action-mappings>
<action attribute="HelloForm"
path="/HelloWord"
type="hp.HelloAction"
name="HelloForm"
scope="request"
validate="true"
input="/hello.jsp">
<forward name="sayHello" path="/hello.jsp"></forward>
</action>
配置文件如上，但是这样还是无法执行validate方法的验证。为什么？

Answer 1

FORM 继承validateACTIONFORM

Answer 2

你的属性文件配置了没?ApplicationResources.properties
还有你的页面用标签输出了没?
我想问题应该出现在这里!!

Answer 3

嘿嘿，我觉得没有理由，要配置的就那么一个地方，关注....

Answer 4

把public ActionErrors validate(ActionMapping mapping, ServletRequest request)中的第二个参数换成HttpServletRequest
