IntelliJ Idea 中的 Geo Viewer 很酷-java教程-PHP中文网

你好老朋友

感谢 波兹南 Java 用户组 在一次聚会期间随机选择我来获得 JetBrains IntelliJ Idea Ultimate 许可证，我开始每天使用它。对我来说这并不是全新的软件。我使用 Android Studio 已有近十年了，偶尔会在 IntelliJ 社区版中参与一些副项目。最近在工作中，我一直在使用 VS Code 和 NeoVim。与后者完全不同的 IDE 理念。

我目前恰好在后端工作，IntelliJ 绝对是一个野兽，它的内置工具可以满足您能想象到的一切。

除了对 TypeScript、SQL 和构建配置的常用语言支持之外，还有不错的数据库工具。数据显示类似于Excel电子表格，可以过滤，可以生成DDL代码，画图表等。没什么特别的；其他工具可以实现这一点。

但这只是在 IDE 内部，因此无需更改上下文即可轻松访问。

地理查看器

我偶然注意到了 Geo Viewer 工具。

Geo Viewer in IntelliJ Idea is cool

我正在处理一些地理数据，例如区域和点。 Geo Viewer 开箱即用。不需要插件或配置。至少对于具有 Postgis 设置的 Postgres 来说是这样。

这看起来可能是不必要的视觉效果，但实际上对于调试很有用。想象一下有一个查询从一个表返回另一个表中定义的区域内的点。能在实际地图上看到结果真是太棒了。

让我们把它付诸实践

我使用 ChatGPT 生成波兰各省的数据。这并不完全是坏事...它们都在正确的位置，只是太小了。

城市位置的数据没问题。

为了在单个地理视图上可视化城市和区域，我使用了一个简单的 SQL 视图。我从大学开始就没有接触过SQL，所以这也是一次有趣的经历:D

受到 Kacper Koza 上一次 JUGtoberfest 演示的影响，我开始使用更多 IntelliJ 快捷方式。并关闭了标签。到目前为止一切顺利，我的鼠标得到了休息。
