"基于气象分析的hadoop可视化平台"是一个利用大数据处理技术和可视化工具来解析和展示气象数据的项目。这个项目特别关注了2022年的温度、空气质量、降水量和湿度这四个关键气象指标。 描述了该项目的技术栈和实现流程。项目采用了集成开发环境IDEA中的Maven进行项目构建与管理，这使得依赖管理和构建过程更加规范和高效。Maven通过定义项目的结构和依赖关系，帮助开发者自动化构建项目，减少了手动管理库文件的繁琐工作。 接下来，项目利用了Apache Hadoop这一分布式计算框架来处理大规模的气象数据。Hadoop提供了分布式文件系统HDFS，用于存储大量数据，以及MapReduce编程模型，用于并行处理数据。在这个场景下，Hadoop可能是用来对气象数据进行预处理、清洗和聚合，以便后续分析。 数据库连接方面，项目可能使用了JDBC（Java Database Connectivity）驱动，使得Java程序能够与数据库进行交互。数据可能被存储在关系型数据库中，如MySQL或PostgreSQL，用于长期存储和查询气象数据。 前端部分，项目使用了ECharts，这是一个基于JavaScript的数据可视化库，能够创建丰富的图表和图形，如折线图、柱状图等，用于直观展示气象变化趋势。ECharts与后端Java Web服务结合，通过Ajax请求获取数据，然后在浏览器端动态渲染图表，为用户提供了交互式的可视化体验。 "hadoop"表明该项目的核心在于使用Hadoop处理和分析大量气象数据，这通常涉及到大数据的分布式存储和计算。 【文件列表】中的文件包括不同日期的屏幕截图，可能展示了项目中不同时间点的界面和结果，例如数据的加载、处理过程或可视化效果。Excel文件（如tb_rainfall.xlsx、temperature.xlsx等）则很可能包含了原始的气象数据，每一列代表特定的气象指标，每一行对应一个观测点或时间点的数据。而db_开头的文件可能与数据库表结构或导入数据有关，例如db_humidity.xlsx可能包含了湿度数据的导入模板。 这个项目展示了如何使用现代IT技术，如Hadoop、Maven、ECharts等，从数据收集、处理、存储到展示的全链路处理气象数据，并提供了用户友好的可视化界面，有助于气象学家和决策者理解气候变化和做出相应预测。
