我正在从数据库中读取/加载环境变量。因此我没有application.properties。

我收到以下错误消息

APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of constructor in com.MyNotificationService required a bean of type 'org.springframework.mail.javamail.JavaMailSender' that could not be found.
    - Bean method 'mailSender' not loaded because AnyNestedCondition 0 matched 2 did not; NestedCondition on MailSenderAutoConfiguration.MailSenderCondition.JndiNameProperty @ConditionalOnProperty (spring.mail.jndi-name) did not find property 'jndi-name'; NestedCondition on MailSenderAutoConfiguration.MailSenderCondition.HostProperty @ConditionalOnProperty (spring.mail.host) did not find property 'host'


Action:

Consider revisiting the conditions above or defining a bean of type 'org.springframework.mail.javamail.JavaMailSender' in your configuration.

似乎 spring 无法创建 MyNotificationService 的实例，因为它的构造函数需要 JavaMailSender 类型的 bean。

在堆栈的更下方，您可以看到它无法找到几个属性。如果您想从 db 加载属性，请使用下面的教程
