import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import com.opensymphony.xwork2.ActionSupport; public class LoginAction extends ActionSupport { private List<Map<String, String>> list; @Override public String execute() { list = new ArrayList<Map<String, String>>(); Map<String, String> map = new HashMap<String, String>(); map.put("name", "zhangsan"); map.put("sex", "boy"); map.put("age", "25"); list.add(map); return "success"; } public List<Map<String, String>> getList() { return list; } public void setList(List<Map<String, String>> list) { this.list = list; } }
jsp中使用s:iteraotr标签遍历List
<s:iterator id="map" value="list" status="state"> <!-- 打印List --> <s:property value="list[#state.index]" /> <br> <!-- 打印Map --> <s:iterator value="list[#state.index]"> <s:property value="key" />: <s:property value="value" /> <br> </s:iterator> </s:iterator>
输出如图:
