Java Swing天气预报系统（数据库+天气后台管理）
Java Swing天气预报系统
今天写了个Java GUI的窗口应用，比较简单，主要用到数据库（mysql）、功能有：切换城市、展示不同城市天气、后台天气数据管理和展示
由于天气数据接口API为付费，免费的API接口返回的天气数据又比较少，所以这里我的天气数据都存在了数据库里，一共展示6天的天气
这里写目录标题
- Java Swing天气预报系统
-
- 应用窗口
- 主要代码
- 写在最后
应用窗口
1、天气主页面：
2、天气数据后台页面：
其中天气主页面支持切换城市、展示天气
天气后台管理页面支持天气数据增删改查
主要代码
天气主页面：WeatherMainFrame.java
