Struts1中validator为什么不起作用？

LiuMelody 2009-06-05 03:53:40

我用的是Eclipse 3.2、MyEclipse 5.0
自动生成的struts.jar、commons-validator.jar、jakarta-oro.jar
自动生成的validator-rules.xml，里面用的是validator_1_1_3.dtd
我自己写了个validation.xml，也用用的是validator_1_1_3.dtd
查看过这两个帖子：http://topic.csdn.net/t/20060508/09/4735225.html、http://hi.baidu.com/luxiaoyi/blog/item/e302f0132463b0065aaf5384.html
不清楚为什么会不生效（就是我在表单中不输入任何值，然后submit，它就直接转到成功页面去了），是不是也是因为jar包不匹配？但是这些jar包是由Eclipse自动一起生成的啊。。。

具体代码如下：

呵呵，有时候，编辑器的缓存被引出程序的bug

谢谢edisonwin！

我加了return super.validate(mapping,request); 这句
或者直接把整个validate方法删掉
结果还是一样。。。真是奇怪

这个方法被你重写了，改成
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request)
{
// TODO Auto-generated method stub
return super.validate(mapping,request);
}

谢谢bear13!

1. 我改为：
===============================
<body>
<html:javascript formName="userRegistrationForm"/>
<html:form action="/userRegistration" onsubmit="return userRegistrationForm(this);">
<html:errors/><br/>
name : <html:text property="username"/><br/>
password : <html:password property="password"/><br/>
<html:submit/><html:cancel/>
</html:form>
</body>
===============================
或
<body>
<html:javascript formName="userRegistrationForm"/>
<html:form action="/userRegistration" onsubmit="return validateUserRegistrationForm(this);">
<html:errors/><br/>
name : <html:text property="username"/><br/>
password : <html:password property="password"/><br/>
<html:submit/><html:cancel/>
</html:form>
</body>
===============================

都不行！还是一样，没有什么效果。

2. 加javascript是客户端验证吧，我是先验证服务器端的
