Struts 自动将字符串转换为垃圾值时出错

Question

我正在从数据库中获取字符串值和其他数据并设置为 class 对象的字符串，但我在网页中显示的字符串显示垃圾值，如 -3892 之类的东西

在ClassTravelVO String

private String travelCombnationId;

//Setter getters
public String getTravelCombnationId() {
    return travelCombnationId;
}
public void setTravelCombnationId(String travelCombnationId) {
    this.travelCombnationId = travelCombnationId;
}

在数据库中 Class

while (rs.next()) {
    travel = new TravelVO();
    travel.setTravelId(rs.getLong("TRAVEL_ID"));
    travel.setTravelCombnationId(rs.getString("TRAVEL_COMB_ID")); // Showing Value properly here
    System.out.println(travel.getTravelCombnationId());
    travel.setTravelReason(rs.getString("TRAVEL_REASON"));
    myApprovedRequests.add(travel);
}

操作Class

iAcceptForwardList = TravelDAO.getInstance().myPendingRequest();

JSP 页数

<s:iterator value="iAcceptForwardList" var="quesvar" status="questat">
    <tr>
       <td><s:text name="%{iAcceptForwardList[#questat.index].travelCombnationId}"/></td>
    </tr>
</s:iterator>

当我进入 DAO 时它正确显示了值

显示在系统输出 T-268-300-2018-Jul

其在 jsp 页上的显示值 -72737

请帮忙..

使用属性而不是直接使用对象变量

<s:property value="%{iAcceptForwardList[#questat.index].travelCombnationId}" />
