spring-boot-actuator 1.2.5.RELEASE 在容器启动时抛出错误

spring-boot-actuator 1.2.5.RELEASE throws error on container start up

一点背景: 我正在尝试在生产中的 spring MVC 应用程序中使用 spring-boot-actuator。它不是 spring-boot-application。

我用 spring-boot-actuator 组合了一个简单的 spring MVC 应用程序。 示例代码可用 here。这是克隆和重现错误的简单应用程序。我有自述文件,里面有说明。

我已经使用了 spring-boot-actuator 1.1.1.RELEASE 依赖项并且它工作正常。 但是,当我想使用 1.2.5.RELEASE 时,这就是我在容器启动期间遇到错误的地方。

SEVERE: StandardWrapper.Throwable
java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.actuate.autoconfigure.EndpointAutoConfiguration$RequestMappingEndpointConfiguration#requestMappingEndpoint due to internal class not found. This can happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)

您使用的是不兼容的旧版本 Spring Framework。我猜是 4.0.x.

SmartInitializingSingleton 是 Spring Framework 4.1 中的新增功能。此外,described in the documentation、Spring Boot 1.2.5 需要 Spring Framework 4.1.5.RELEASE 或更高版本。
