Struts的动态表单的应用

(str.length() == 0));
}

public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if (nullOrBlank((String)this.get("lastName"))) {
errors.add("lastName",
new ActionError("article1.lastName.missing"));
}
if (nullOrBlank((String)this.get("firstName"))) {
errors.add("firstName",
new ActionError("article1.firstName.missing"));
}
if (nullOrBlank((String)this.get("street"))) {
errors.add("street",
new ActionError("article1.street.missing"));
}
if (nullOrBlank((String)this.get("city"))) {
errors.add("city", new ActionError("article1.city.missing"));
}
if (nullOrBlank((String)this.get("state"))) {
errors.add("state",
new ActionError("article1.state.missing"));
}
if (nullOrBlank((String)this.get("postalCode"))) {
errors.add("postalCode",
new ActionError("article1.postalCode.missing"));
}
if (nullOrBlank((String)this.get("phone"))) {
errors.add("phone", new ActionError("article1.phone.missing"));
}
return errors;
}

}
如果是这样，我们就要更改struts-config.xml来使用DynaActionForm的子类，这样的效果似乎是又回到了先前的样子（为每一个表单写DynaActionForm），呵呵。。。

所以推荐的做法是使用struts1.1种的Validator Framework,这方面的内容在以后的文章中在说明。
