Struts入門レベルのログインフォームを作ってみた。 - ウエンのITスペシャリストへの道〜虎の巻〜

今回はログインフォームを作ってみました。
うんちくより先に、吟じます。

package section1;

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;

public class LoginAction extends Action{

	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		LoginForm param = (LoginForm)form;
		if(isCheck(param)) {
			return mapping.findForward("success");
		} else {
			return mapping.findForward("error");
		}
	}

	private boolean isCheck(LoginForm param) {
		return "admin".equals(param.getName()) && "admin".equals(param.getPass());
	}

	
}

package section1;

import org.apache.struts.action.ActionForm;

public class LoginForm extends ActionForm{

	private String name;
	
	private String pass;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getPass() {
		return pass;
	}

	public void setPass(String pass) {
		this.pass = pass;
	}
}

     This is a blank Struts configuration file with an example
     welcome action/page and other commented sample elements.

     Struts Validator is configured using the factory defaults
     and is ready-to-use.

     NOTE: If you have a generator tool to create the corresponding Java classes
     for you, you could include the details in the "form-bean" declarations.
     Otherwise, you would only define the "form-bean" element itself, with the
     corresponding "name" and "type" attributes, as shown here.
