jsp – EL通过Integer键获取HashMap的值

Map<Integer, String> odometerMap = new LinkedHashMap<Integer, String>();
    odometerMap.put(0, getLocaleForKey("drop-down.any"));
    odometerMap.put(1, "< 1000");
    odometerMap.put(2, "1000 - 5000");
    odometerMap.put(3, "5000 - 10000");
    odometerMap.put(4, "10000 - 20000");
    odometerMap.put(5, "20000 - 30000");
    odometerMap.put(6, "30000 - 40000");
    odometerMap.put(7, "40000 - 60000");
    odometerMap.put(8, "60000 - 80000");
    odometerMap.put(9, "> 80000");

我在JSP中的目标是打印例如${odometerMap [2]}(结果为空字符串)：

<c:out value="${odometerMap[2]}"/>

如果我只打印${odometerMap},我会得到完整的地图：

{0=Any, 1=< 1000, 2=1000 - 5000, 3=5000 - 10000, 4=10000 - 20000, 5=20000 - 30000, 6=30000 - 40000, 7=40000 - 60000, 8=60000 - 80000, 9=> 80000}

如何只打印我选择的元素？例如：2？

谢谢

Map<Long, String> odometerMap = new LinkedHashMap<Long, String>();
odometerMap.put(0L, getLocaleForKey("drop-down.any"));
odometerMap.put(1L, "< 1000");
