我一直在看this回答 spring boot application.properties 中的引用环境变量。

但是，当我这样做时，会返回一个错误，表示无法解析 $(MYAPP_MYSQL_DB_USERNAME}

应用程序属性

spring.datasource.username = ${MYAPP_MYSQL_DB_USERNAME}

错误

我已经在 .bash_profile 中设置了环境变量。然后我source .bash_profile。

我得到结果时

> echo $MYAPP_MYSQL_DB_USERNAME
> root

我还重新启动了 eclipse，只是为了覆盖所有基础。

最佳答案

您已在 .bash_profile 中设置变量MYAPP_MYSQL_DB_USERNAME。我认为您正在将 eclipse 作为桌面应用程序启动。如果您将 Eclipse 作为桌面应用程序启动，它无法从 .bash_profile 读取变量。要解决此问题，您可以使用以下方法:

您可以从命令提示符启动 Eclipse。

或者

在.profile文件中设置环境变量。
