我在 src/main/config 路径中​​有带有 jdbc.url、jdbc.username 和 jdbc.password 的 database.properties。

另外，我想问一下我的项目结构是否正确。

另外，我想问一下我的项目结构是否正确。

不，这实际上导致了您的问题。即使src/main/config在 Eclipse 中被标记为项目目录，maven 也不会以任何特殊方式对待它，特别是它不会在 CLASSPATH 中包含该文件夹。检查您构建的 WAR 文件，它甚至不包含这些文件！

通过简单地将所有*.properties文件移动到src/main/resources您的应用程序应该构建和运行良好。
