运用对象 Action,ActionForm;

1：web.xml资料配备

action

org.apache.struts.action.ActionServlet

config

/WEB-INF/struts-config.xml

debug

三

detail

三

零

action

*.do

index.jsp

2：struts-config.xml资料配备

attribute="addForm"

name="addForm"

path="/action"

type="MyAction.MyAction">

name="addForm"

path="/action二"

type="MyAction.MyAction二">

name="addForm"

path="/action三"

type="MyAction.MyAction三"

>

3：实业Form资料

package MyForm;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionMapping;

public class form extends ActionForm {

private String num一;

public String getNum一() {

//测试运行

System.out.println("num一.get()");

return num一;

}

public void setNum一(String num一) {

//测试运行

System.out.println("num一.set()");

this.num一 = num一;

}

}

4：实业Action对象

对象1

package MyAction;

import java.io.IOException;

import javax.servlet.ServletException;

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 MyAction extends Action {

public ActionForward execute(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response) {

ActionForward af = null;

//获取Form页面值

MyForm.form f = (MyForm.form)form;

//测试值

System.out.println("Form值"+f.getNum一());

//测试运行

System.out.println("Action.execute()");

//设定跳转

af = mapping.findForward("return");

//带跳转页面信息回来到servlet资料内实施跳转

return af;

}

}

对象二；

package MyAction;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

public class MyAction二 extends Action{

public ActionForward execute(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response)

throws Exception {

MyAction ma = new MyAction();

//Action中调用另一个Action对象步骤;

//同一个工程停的对象，直接产成施用

ma.execute(mapping, form, request, response);

ActionForward af = mapping.findForward("return二");

return af;

}

}

对象三

package MyAction;

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.ActionMapping;

import org.apache.struts.action.ActionForward;

public class MyAction三 extends Action{

@Override

public ActionForward execute(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response)

throws Exception {

//测试运行

System.out.println("MyAction三.execute()");

//跳转到另一个Action，return为config资料内对应Action配备停的forward属性

ActionForward af = mapping.findForward("return");

return af;

}

}

3：实业Form资料

package MyForm;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionMapping;

public class form extends ActionForm {

private String num一;

public String getNum一() {

//测试运行

System.out.println("num一.get()");

return num一;

}

public void setNum一(String num一) {

//测试运行

System.out.println("num一.set()");

this.num一 = num一;

}

}

4：实业Action对象

对象1

package MyAction;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

public class MyAction extends Action {

public ActionForward execute(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response) {

ActionForward af = null;

//获取Form页面值

MyForm.form f = (MyForm.form)form;

//测试值

System.out.println("Form值"+f.getNum一());

//测试运行

System.out.println("Action.execute()");

//设定跳转

af = mapping.findForward("return");

//带跳转页面信息回来到servlet资料内施行跳转

return af;

}

}

对象二；

package MyAction;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

public class MyAction二 extends Action{

public ActionForward execute(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response)

throws Exception {

MyAction ma = new MyAction();

//Action中调用另一个Action对象步骤;

//同一个工程停的对象，直接产成应用

ma.execute(mapping, form, request, response);

ActionForward af = mapping.findForward("return二");

return af;

}

}

对象三

package MyAction;

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.ActionMapping;

import org.apache.struts.action.ActionForward;

public class MyAction三 extends Action{

@Override

public ActionForward execute(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response)

throws Exception {

//测试运行

System.out.println("MyAction三.execute()");

//跳转到另一个Action，return为config资料内对应Action配备停的forward属性

ActionForward af = mapping.findForward("return");

return af;

}
