如何在 Spring Boot 中禁用邮件健康检查？

Question

我想在 spring 引导中禁用邮件健康检查，因为这些值将在运行时设置。 我发现在 Spring Boot 的某些 GitHub 问题中提到了这一点，但提到的配置有所不同。

这是我启动 Spring 引导应用程序后的异常。

我尝试将其添加到我的配置中，但它引发了相同的异常。

mail:
  test-connection: false
  properties:
    management:
      health:
        mail:
          enabled: false

在 Spring 引导中禁用邮件健康检查的正确配置是什么？

Answer 1

尝试

management:
  health:
    mail:
      enabled: false
