我的application.properties文件是正确的

在服务器上运行此代码时出现问题，因此我无法找到确切的错误。我尝试过使用不同版本的hibernate和mysql连接器，但问题仍然存在。

尝试使用-

@PropertySource({ "classpath:application.properties" }) //Add this annotaion at your class

以及

希望这对您有用：）

如果您正确分析stacktrace，它会清楚地指出问题是“未找到必需的密钥[jdbc.driverClassName]”。请确保属性文件具有提到的密钥。您还需要在配置类中设置PropertySource

@PropertySource("classpath:application.properties")

看起来没有设置属性jdbc.driverClassName

environment.getProperty("jdbc.driverClassName"); //Use this to read a property

@PropertySource("classpath:application.properties")
