loginaction.java

对入学者很实用用JAVA的基本语言写的

package com.yourcompany.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;
import org.apache.struts.action.ActionMessages;

import com.yourcompany.struts.form.LoginForm;

@SuppressWarnings("serial")
public class LoginAction extends Action {

	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) {
		LoginForm loginForm = (LoginForm) form;
		if (!"accp".equals(loginForm.getUsid())){
			ActionMessages errors = new ActionMessages();
			errors.add("usid", new ActionMessage("用户名不对",false));
			this.saveErrors(request, errors);
			return mapping.getInputForward();
		}
		if (!"accp".equals(loginForm.getPass())){
			ActionMessages errors = new ActionMessages();
			errors.add("pass", new ActionMessage("密码不对",false));
			this.saveErrors(request, errors);
			return mapping.getInputForward();
		}
		return mapping.findForward("it");
	}
}
