Jsp 从数据库值中选择单选按钮

我试图从数据库值中选择单选按钮

我正在努力

value="%{userInfoSettings[0].value}" 

它没有选择任何收音机盒

在迭代userInfoSettings时，它会显示正确的值

   <s:iterator value="spList" var="r" status="st">
       <s:property value="description"/>
       <s:hidden name="uisList[%{#st.index}].settingParam.id" value="%{id}"/>
       <s:radio  name="uisList[%{#st.index}].value" 
                 list="#{'Yes':'Send email','No':'Dont inform'}"
                 value="%{userInfoSettings[0].value}"/>

         <s:iterator value="userInfoSettings" var="x">
              val <s:property value="value"/>
              id <s:property value="id"/>
         </s:iterator>
      id  <s:property value="id"/>
   </s:iterator>

SettingParam.java

 public class SettingParam implements java.io.Serializable {
    private Long id;
    private String description;
    private int groupId;
    private Date adddate;
    private Set userInfoSettings = new HashSet(0);
    private Set userProfileSettings = new HashSet(0);
    private Set userPostSettings = new HashSet(0);
    private List<UserInfoSetting> userInfoSettingList = new ArrayList<UserInfoSetting>();
    private List<UserProfileSetting> userProfileSettingList = new ArrayList<UserProfileSetting>();
    private List<UserPostSetting> userPostSettingList = new ArrayList<UserPostSetting>();
    //gettersetter
}

请显示您的java对象什么是userInfoSettings[0]的值。值？其值为“是”或“否”userInfoSettings是使用c:set标记或类似标记设置的吗？否从db上的db获取数据值它是“是”或“否”

public class UserInfoSetting  implements java.io.Serializable {
     private Long id;
     private Atom atom;
     private SettingParam settingParam;
     private String value;
     private Timestamp adddate;
      //getter setter
      }

 public class SettingParam implements java.io.Serializable {
    private Long id;
    private String description;
    private int groupId;
    private Date adddate;
    private Set userInfoSettings = new HashSet(0);
    private Set userProfileSettings = new HashSet(0);
    private Set userPostSettings = new HashSet(0);
    private List<UserInfoSetting> userInfoSettingList = new ArrayList<UserInfoSetting>();
    private List<UserProfileSetting> userProfileSettingList = new ArrayList<UserProfileSetting>();
    private List<UserPostSetting> userPostSettingList = new ArrayList<UserPostSetting>();
