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

Question

我的 Spring Boot 应用程序出现问题，不愿意运行。

根据日志，出现这种情况的原因是未绑定 spring.resources.cache-period 属性。 然而，这个属性是在 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。

application.properties

Answer 1

正如@Stephane Nicoll 建议的那样，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。

Answer 2

我遇到了同样的问题。 您应该删除版本以使用 spring-boot 相同的版本

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>

Answer 3

还要注意用户的 devtools 全局配置文件： ~/.spring-boot-devtools.properties

这可能包含已弃用的值，例如其中提到的 spring.resources.cache-period，它们不再有效。

=> 就我而言，删除这个旧值解决了同样的错误！

还可以查看 spring boot 的文档以了解配置顺序：
