3. ActionForm 클래스
public class HelloWorldForm extends ActionForm {
/*
* Generated fields
*/
/** msg property */
private String msg;
/*
* Generated Methods
*/
/**
* Method reset
* @param mapping
* @param request
*/
public void reset(ActionMapping mapping, HttpServletRequest request) {
// TODO Auto-generated method stub
}
/**
* Returns the msg.
* @return String
*/
public String getMsg() {
return msg;
}
/**
* Set the msg.
* @param msg The msg to set
*/
public void setMsg(String msg) {
this.msg = msg;
}
}
4. action 클래스
[1] HelloWorld1Action 류
public class HelloWorld1Action extends Action{
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
// TODO Auto-generated method stub
String str = "hello zhao ";
request.setAttribute("helloWorld", str);
return mapping.findForward("show");
}
}
[2] HelloWorld 2Action 류
public class HelloWorld2Action extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
HelloWordForm helloWordForm = (HelloWordForm) form;// TODO Auto-generated method stub
String msg = helloWordForm.getMsg();
request.setAttribute("helloWorld", msg);
//response.setCharacterEncoding("utf-8");
//response.setContentType("text/html;charset=utf-8");
return mapping.findForward("show");
}
}
[3] ThreeInputAction 클래스
public class ThreeInputAction extends DispatchAction {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
HelloWordForm helloWordForm = (HelloWordForm) form;// TODO Auto-generated method stub
return null;
}
}
2. struts - config. xml 설정
1. 입력 페이지 가 없고 action 과 출력 만 있 습 니 다.
<action-mappings >
<action path="/helloWorld1" type="com.zhao.struts.action.HelloWorld1Action">
<forward name="show" path="/WEB-INF/jsp/show.jsp" />
</action>
</struts-config>
2. 입력 페이지 가 있 고 bean 이 없 으 면 action 은 request. getParameter ("msg") 를 사용 해 야 합 니 다.매개 변수
3. 비 안 이 있다
<form-beans >
<form-bean name="helloWorldForm" type="com.zhao.struts.form.HelloWorldForm" />
</form-beans>
<action-mappings >
<action
attribute="helloWorldForm"
name="helloWorldForm"
path="/helloWorld2"
scope="request"
type="com.zhao.struts.action.HelloWorld2Action"
validate="false">
<forward name="show" path="/WEB-INF/jsp/show.jsp" />
</action>
</action-mappings >
4. 페이지 설정 입력
[1] 직접 / form / input1. jsp 탐색 은 설정 하지 않 아 도 됩 니 다.
[2]
<!--struts -->
<action forward="/WEB-INF/jsp/input1.jsp" path="/input2" />
<action include="/WEB-INF/jsp/input1.jsp" path="/input3" />
<!--struts -->
<action
path="/input4"
type="org.apache.struts.actions.ForwardAction"
parameter="/WEB-INF/jsp/input1.jsp" />
5. 다 중 단추 설정
<action
attribute="helloWorldForm"
name="helloWorldForm"
parameter="method"
path="/threeInput"
scope="request"
type="com.zhao.struts.action.ThreeInputAction">
<forward name="show" path="/WEB-INF/jsp/show.jsp" />
