一、在List中放置自定义的Bean
1、定义一个MeicdNameForm.java
package com.sunrex.demo02.form;
import org.apache.struts.action.ActionForm;
public class MeicdNameForm extends ActionForm{
private String meicd;
public String getMeicd() {
return meicd;
}
public void setMeicd(String meicd) {
this.meicd = meicd;
}
}
?
2、定义MeicdNameAction.java类
package com.sunrex.demo02.action;
import java.util.ArrayList;
import java.util.List;
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.sunrex.demo02.bean.MeicdBean;
public class MeicdNameAction extends DispatchAction {
@Override
protected ActionForward unspecified(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
return mapping.findForward("index");
}
public ActionForward select(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
List<MeicdBean> meicds = new ArrayList<MeicdBean>();
for(int i=0; i<10; i++) {
MeicdBean mb = new MeicdBean();
mb.setMeicd("11"+i);
mb.setMeinm("店名-->" + i);
mb.setMeicdAndMeinm(mb.getMeicd() + ":" + mb.getMeinm());
meicds.add(mb);
}
request.setAttribute("items", meicds);
return mapping.findForward("select");
}
}
?3、定义MeicdBean.java
package com.sunrex.demo02.bean;
public class MeicdBean {
private String meicd;
private String meinm;
private String meicdAndMeinm;
public String getMeicdAndMeinm() {
return meicdAndMeinm;
}
public void setMeicdAndMeinm(String meicdAndMeinm) {
this.meicdAndMeinm = meicdAndMeinm;
}
public String getMeicd() {
return meicd;
}
public void setMeicd(String meicd) {
this.meicd = meicd;
}
public String getMeinm() {
return meinm;
}
public void setMeinm(String meinm) {
this.meinm = meinm;
}
}
?
4、index.jsp
<%@ page language="java" contentType="text/html; charset=GB18030"
pageEncoding="GB18030"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB18030">
<title>Insert title here</title>
</head>
<body>
<a href="select.do?method=select&meicd=116">go</a>
</body>
</html>
?5、select.jsp
<%@ page language="java" contentType="text/html; charset=GB18030"
pageEncoding="GB18030"%>
<%@ taglib prefix="html" uri="http://struts.apache.org/tags-html"%>
<%@ taglib prefix="bean" uri="http://struts.apache.org/tags-bean"%>
<%@ taglib prefix="logic" uri="http://struts.apache.org/tags-logic"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB18030">
<title>Insert title here</title>
</head>
<body>
<html:form action="/select.do">
<html:select property="meicd">
<html:options property="meicd" collection="items" labelProperty="meicdAndMeinm"/>
</html:select>
</html:form>
</body>
</html>
?
注意:<html:select property="meicd">与MeicdNameForm.java中的meicd属性对应。
点击index.jsp页面的go后,运行结果是:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
