Question

我在启动restful spring boot app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}

我检查了C:/windows/Temp，但我找不到jetty-docbase.8144885224534920922.8080

如果有人可以帮我解决这个问题，那将会很棒。我如何创建该文件以便jetty识别它？

下面是完整的堆栈跟踪。

非常感谢提前......

您的实际例外是：

引起：java.lang.IllegalArgumentException：无法解析占位符＆＃39; build.version＆＃39;在字符串值＆＃34; $ {build.version}＆＃34;

这意味着，Spring应用程序无法创建上下文并启动，因为它无法创建一些bean，因为它无法解析某些必需的自动装配变量，在这种情况下它是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。或者你可以找到这个bean（它的名字是buildInformationProperties，这个值应该是自动的，并试着找出，为什么你没有默认拥有它。

springboot app无法启动 - 错误（已停止o.s.b.c.e.j.JettyEmbeddedWebAppContext）
