객체로 데이터 받기 / set으로 데이터 받기

1. 객체로 데이터 받기

뷰 : 

<form action="insert.action">

<div align="center">

<table border="1">

<tr>

<td>id</td>

<td><input type="text" name="id"></td>

</tr>

<tr>

<td>name</td>

<td><input type="text" name="name"></td>

</tr>

<tr>

<td>mail</td>

<td><input type="text" name="mail"></td>

</tr>

<tr>

<td>text</td>

<td><textarea rows="10" cols="50" name="text">

</textarea></td>

</tr>

<tr align="center">

<td colspan="2"><input type="submit" value="Submit"> <input

type="reset" value="Reset"></td>

</tr>

</table>

</div>

액션 :

public class InsertAction implements Action , ModelDriven<GuestBook>,Preparable

{

private GuestBook gb = null;

  //실행 순서

 //prepare -> getModel -> execute

@Override

public void prepare() throws Exception 

{ //객체 준비

// TODO Auto-generated method stub

this.gb = new GuestBook();

}

@Override

public GuestBook getModel() 

{ //view에서 입력 받은 값을 저장할 객체를 반환

// TODO Auto-generated method stub

return gb;

}

@Override

public String execute() throws Exception 

{ // 실행

// TODO Auto-generated method stub

GuestBookDAO dao = GuestBookDAO.getInstance();

dao.insert(gb);

return SUCCESS;

}

}

2. set으로 데이터 받기

뷰 : 

<a href="read.action?num=${gb.num}"> 

액션:

public class ReadAction implements Action

{

private GuestBook gb = null;

private int num = 0;

public void setNum(int num) 

{

this.num = num;

System.out.println(num);

}

@Override

public String execute() throws Exception 

{

// TODO Auto-generated method stub

GuestBookDAO dao = GuestBookDAO.getInstance();

gb = dao.read(this.num);

System.out.print(gb.getId());

return SUCCESS;

}

public GuestBook getGb() 

{

return gb;

}

}
