jsp页面具体获取springmvc后台传入的List<object>某下标的属性

Question

如
class Project{
      private List<ProjectDoc> pds;
      setters and getters....
}
class ProjectDoc{
      private  id;
      private name;
      private index; //下标
}
class ProjectController{
        public String test(Model model){
                  model.addAttribute("project",project);
        }
}问jsp页面怎么获取具体下标的projectDoc.name的值
有一个麻烦的方法但我不行这么做
 <c:forEach items="${project.projectDocs}" var="item" >
                        <c:if test="${item.index==4 }">
                        <button id="${item.name}"  onclick="viewFile(this)">预览</button>
                        </c:if>
                    </c:forEach>问有没有简单直接的,比如这种形式的${project.projectDoc[index].name} 获取??

Answer 1

将list转化array  数组，采用数组下标获取对象 获取对象属性

Answer 2

<c:forEach items="${project.pds}" var="item" >
          <c:if test="${item.index==4 }">
                <button id="${item.name}"  onclick="viewFile(this)">预览</button>
          </c:if>
</c:forEach>

Answer 3

${project.projectDocs}改成${project.pds}
