如何获取Servlet Context中的所有属性名称(嵌套与否),如果是映射或列表则迭代？

ServletContext context = getServletContext();
Enumeration<String> attributeNames = context.getAttributeNames();
while (attributeNames.hasMoreElements()) {
    String attributeName = attributeNames.nextElement();
    Object attributeValue = context.getAttribute(attributeName);
    // 处理属性值
}

if (attributeValue instanceof Map) {
    Map<?, ?> map = (Map<?, ?>) attributeValue;
    for (Map.Entry<?, ?> entry : map.entrySet()) {
        // 处理Map中的每个键值对
    }
} else if (attributeValue instanceof List) {
    List<?> list = (List<?>) attributeValue;
    for (Object item : list) {
        // 处理List中的每个元素
    }
}
