java - Spring Boot 应用程序无法运行 - spring.resources.cache-period 未绑定(bind)

Question

我的 Spring Boot 应用程序出现问题，无法运行。

根据日志，出现这种情况的原因是未绑定(bind) spring.resources.cache-period 属性。 然而，此属性是在 application.properties 中设置的，编译器甚至会返回它的值。

如果有人能帮我解决这个问题，我将不胜感激。

Answer 1

正如@Stephane Nicoll 所建议的，我已将 spring-boot-devtools 版本更改为与我的 Spring Boot 版本对应的版本。这与删除之前提供的 spring.resources.cache-period 属性一起解决了这个问题。
