Object＞＞，Map＜String,List＜Map＜String, Object＞＞＞多方式循环遍历
例如,创建一个服务类来访问这些数据: importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.stereotype.Service;importjava.util.List;importjava.util.Map;@ServicepublicclassProductService{@AutowiredprivateYmlConfigReaderymlConfigReader;publicvoiddisplayProducts(){List<Map<String,Objec...

解析Map<String, String>:根据YAML文件的结构,将对应的部分解析为Map<String, String>对象。具体的解析方式取决于所使用的YAML解析库和目标编程语言。 注入Map<String, String>:将解析得到的Map<String, String>对象注入到相应的代码逻辑中,以便在程序执行过程中使用。
