struts2——s:checkboxlist标签！！！

checkboxlist：

1）checkboxlist默认是横着排列，要想竖着排列就比较麻烦，，要覆盖strut2的css或者覆盖struts2的方法。

2）同样的环境，把后面一个checkboxlist的name改为map：

<s:checkboxlist name="map" list="map" listKey="key" listValue="value"/>

默认就全部选中了，不知道什么原因。

action类：

import java.util.HashMap; import java.util.Map; import java.util.Vector; import com.opensymphony.xwork2.ActionSupport; public class UIAction extends ActionSupport { private Vector vector; private Map map; public String execute() throws Exception { UserInfo u1 = new UserInfo("1", "张三"); UserInfo u2 = new UserInfo("2", "李四"); UserInfo u3 = new UserInfo("3", "王五"); vector = new Vector(); vector.add(u1); vector.add(u2); vector.add(u3); map = new HashMap(); map.put("101", "小张"); map.put("102", "小李"); map.put("103", "小王"); return "success"; } public Map getMap() { return map; } public void setMap(Map map) { this.map = map; } public Vector getVector() { return vector; } public void setVector(Vector vector) { this.vector = vector; } }

dto类：

public class UserInfo { private String userno; private String username; public UserInfo() {} public UserInfo(String userno, String username) { this.userno = userno; this.username = username; } public String getUserno() { return userno; } public void setUserno(String userno) { this.userno = userno; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } }

jsp:

<s:checkboxlist name="foo" list="vector" listKey="userno" listValue="username"/><s:checkboxlist name="foo" list="map" listKey="key" listValue="value"/>
