关于EL表达式 操作map

Question

[code="java"]
Map> colorMap=goodsService.getGoodsColor();
request.getSession().setAttribute("colorMap", colorMap);
[/code]

问题是 用el表达式怎么在指点的key的情况下取出List里的值?

[code="java"]
GoodsColor类

public String getColorName() {
    return colorName;
}
public void setColorName(String colorName) {
    this.colorName = colorName;
}
public double getPrice() {
    return price;

}
public void setPrice(double price) {
    this.price = price;
}

[/code]

[code="java"]

            <c:forEach items="${colorMap}" var="colorMap">
                //${colorMap[3]}这样不是取到key为3的List<GoodsColor>吗?
                //可是${colorMap[3].colorName}却报错
                <p><em>${colorMap[3]}</em></p>
            </c:forEach>

[/code]
