list存放对象 浅谈s:select 标签中list存放map对象的使用

private List<Map<String, String>> maptest = null;

    public List<Map<String, String>> getMaptest() {
 return maptest;
 }

 public void setMaptest(List<Map<String, String>> maptest) {
 this.maptest = maptest;
 }

 

public String maptest(){
 maptest = new ArrayList<Map<String,String>>();
 Map<String, String> map = new HashMap<String, String>();
 map.put("id", "1");
 map.put("name", "dept1");
 maptest.add(map);
 map = new HashMap<String, String>();
 map.put("id", "2");
 map.put("name", "dept2");
 maptest.add(map);
 return SUCCESS;
 }

<s:select list="maptest" listKey="id" listValue="name"></s:select>
