请教:我在编译java文件的时候提示如下信息...
package org.monotonous.struts;
import java.util.Locale;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.util.MessageResources;
import org.apache.commons.beanutils.PropertyUtils;
public final class LogonAction extends Action {
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
Locale locale = getLocale(request);
MessageResources messages = getResources(request);
// Validate the request parameters specified by the user
ActionErrors errors = new ActionErrors();
String username =
(String) PropertyUtils.getSimpleProperty(form, "username");
String password =
(String) PropertyUtils.getSimpleProperty(form, "password");
if ((username != "foo") || (password != "bar"))
errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError("error.password.mismatch"));
// Report any errors we have discovered back to the original form
if (!errors.isEmpty()) {
saveErrors(request, errors);
return (mapping.getInputForward());
}
// Save our logged-in user in the session
HttpSession session = request.getSession();
// Do something with session...
// Remove the obsolete form bean
if (mapping.getAttribute() != null) {
if ("request".equals(mapping.getScope()))
request.removeAttribute(mapping.getAttribute());
else
session.removeAttribute(mapping.getAttribute());
}
// Forward control to the specified success URI
return (mapping.findForward("success"));
}
}
编译时提示如下信息:

这个好想只是警告吧。ActionError 和 ActionErrors 类已经不建议使用了
好象换成使用ActionMessage 和 ActionMessages 了吧
