一个Action对应多个Form
Action:
package com.awp.test.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;
import com.awp.test.form.FirstForm;
import com.awp.test.form.SecondForm;
/**
* @version 1.0
* @author awp
* @date 2009-4-24 上午11:25:49
* @decription 一个Action中包含多个Form
*/
public class MultiFormTestAction extends DispatchAction {
/**
* 第一个Form对应方法
*/
public ActionForward firstForm(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response){
FirstForm beanform = (FirstForm)form;
request.setAttribute("name", beanform.getName());
return mapping.findForward("display");
}
/**
* 第二个Form对应方法
*/
public ActionForward secondForm(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response){
SecondForm beanform = (SecondForm)form;
request.setAttribute("name", beanform.getName());
return mapping.findForward("display");
}
}
Form:
package com.awp.test.form;
import org.apache.struts.action.ActionForm;
public class FirstForm extends ActionForm {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
package com.awp.test.form;
import org.apache.struts.action.ActionForm;
public class SecondForm extends ActionForm {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

Action必须继承DispatchAction，感觉其实一个action还是只能对应一个form
这里的方法其实是利用action的path 多个path可以指向同一个action。
