确保基于配置文件的测试属性具有以下活动属性：

spring.datasource.url=jdbc:postgresql://localhost:5432/your_database
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.username= database_user
spring.datasource.password= database_password

如果您正在使用任何其他数据库，请确保替换postgre。

我也有同样的错误。在application.properties中提供用户名和密码为我解决了这个问题。

“

…原因：java.lang.IllegalArgumentException:“password”的值为Null…

”有什么建议吗？我正在为登录和注册页面的后端进行编码，我的代码中没有看到任何空值。您应该在

应用程序.properties

应用程序.yaml

文件或提供数据库设置的任何地方检查数据源配置。我建议阅读有关此主题的教程，例如，在

应用程序中找到了它。yaml

感谢您的帮助！
