jackson从map获取列表，其中key包含路径(如"child_1_name")

def get_list_from_map(map_data, path):
    keys = path.split("_")  # 拆分路径字符串为各个层级的key
    value = map_data
    for key in keys:
        if isinstance(value, dict):
            value = value.get(key)
        elif isinstance(value, list):
            try:
                index = int(key)
                value = value[index]
            except (ValueError, IndexError):
                value = None
        else:
            value = None
        if value is None:
            break
    if isinstance(value, list):
        return value
    else:
        return []

# 示例用法
map_data = {
    "child": [
        {"name": "Alice"},
        {"name": "Bob"},
        {"name": "Charlie"}
    ]
}
path = "child_1_name"
result = get_list_from_map(map_data, path)
print(result)  # 输出：["Bob"]
