升级 spring-boot-actuator 1.2.5.RELEASE 时无法打开 ServletContext 资源 [/<NONE>]

【问题标题】：Could not open ServletContext resource [/<NONE>] when upgrade spring-boot-actuator 1.2.5.RELEASE升级 spring-boot-actuator 1.2.5.RELEASE 时无法打开 ServletContext 资源 [/<NONE>]
【发布时间】：2017-11-30 15:34:18
【问题描述】：

我正在将 spring-boot-actuator 依赖项与版本 1.1.2 与非 spring boot 应用程序一起使用，现在我想升级到版本 1.2.5.RELEASE 以在我的应用程序中使用默认的芯片健康端点。

当我升级到 1.2.5.RELEASE 应用程序无法启动并出现错误

 Could not open ServletContext resource [/<NONE>]

我可以看到配置位置在 AbstractRefreshableConfigApplicationContext 中设置为 NONE，因此在 XmlBeanDefinitionReader 中它失败并出现此错误。

感谢任何帮助。

这是完整的堆栈跟踪：

    标签： java spring spring-boot-actuator


    【解决方案1】：

    问题是在升级到 spring-boot-actuator 1.2.5.RELEASE 时，由于某种原因，“contextConfigLocation”被删除了，所以我需要做的就是在我的 web.xml 中指定 contextConfiguration，默认情况下 / WEB-INF/applicationContext.xml

    <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

    【讨论】：

    • 没有applicationContext，只有注解的应用怎么办？
    • @VladislavOsipenkov 没有应用程序上下文就没有应用程序
    • @Roberto：我有一个仅注释的应用程序在启动时失败并出现类似的错误link。如何配置仅注释应用程序？
