java - springboot 应用程序未启动 - 错误(已停止 o.s.b.c.e.j.JettyEmbeddedWebAppContext)

Question

我在启动 Restful Spring Boot 应用程序时遇到问题。在看到错误堆栈跟踪时，我可以看到一些与 jetty 相关的异常。

我可以看到下面的日志。

Started o.s.b.c.e.j.JettyEmbeddedWebAppContext@26586b74{/,file:/C:/Windows/Temp/jetty-docbase.8144885224534920922.8080/,AVAILABLE}

我确实检查了C:/windows/Temp，但找不到jetty-docbase.8144885224534920922.8080

如果有人能帮助我解决这个问题，那就太好了。我如何创建该文件以便 jetty 能够识别它？

下面是完整的堆栈跟踪。

提前非常感谢...

Answer 1

您的实际异常是:

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'build.version' in string value "${build.version}"

这意味着 Spring 应用程序无法创建上下文并启动，因为无法创建某些 Bean，因为它无法解析某些所需的 Autowiring 变量，在您的情况下它是一个 build.version 。您可以尝试将此变量添加为命令行参数或将其作为属性添加到 application.properies 文件中。或者您可以找到该 bean(它的名称是 buildInformationProperties，其中该值应该是 autowird，并尝试找出为什么默认情况下没有它。
