我遍历项目列表，如果元素的状态等于学生或老师，则需要显示特定的下拉列表。以下代码显示了所有字段，但未显示任何元素的下拉列表！

 <s:iterator value="listOfPeople" status="element">
   .....
  <s:if test='%{elements[#element.index].Status.equalsIgnoreCase("Student") ||
          elements[#element.index].Status.equalsIgnoreCase("Teacher")}'>

            <s:select name="elements[%{#element.index}].Status"
                               id="elements[%{#element.index}].Status"
                               label="Status"
                               list="#{'Student':'Student','Teacher':'Teacher'}"
                               headerKey = "-1"
                               headerValue=" "
                               value="%{Status}"
             />

    </s:if>

在控制器中：

    PeopleModel peopleModel = new PeopleModel();
    listOfPeople = peopleModel.findPeople();
    System.out.println("size is:" + listOfPeople.size());  //returns 8
    return "listPeople";

我的模特：

    List<People> people = new ArrayList();
    final Session session = HibernateUtil.getSession();
    try {
        final Transaction tx = session.beginTransaction();
        try {

            Criteria criteria = session.createCriteria(People.class, "People")
            people.addAll((List<People>) criteria.list());
            if (!tx.wasCommitted()) {
                tx.commit();
            }
            if (session.isOpen()) {
                session.close();
            }
            System.out.println("size is ::: " + people.size());   //returns 8
            return people;

        } catch (Exception e) {
            tx.rollback();
            e.printStackTrace();
        }
    } finally {
        HibernateUtil.closeSession();
    }
    return null;
}

以下代码的结果是自爆

   Status: ${Status}
   <br/>value : [<s:property value="elements[%{#element.index}].Status" />]



Status : Principle
value : [] Status : Student
value : [] Status : Teacher
value : [] Status : Teacher
value : [] Status : Teacher
value : [] Status : Teacher
value : [] Status : Teacher
value : [] Status : Teacher
value : []

以上结果显示了第一个人的状态与其他人的状态分离，这就是为什么最后一个值[]没有显示任何状态的原因。

如果我取出状态：$ {Status}，结果将是

value : []
value : []
value : []
value : []
value : []
value : []
value : []
value : []
