Spring Boot Samples FileNot发现错误 [英] Spring Boot Samples FileNot found error

问题描述

我是关于春季启动项目的例子。
我已经通过maven编译并创建了一个jar文件，但在运行尝试时出错。

，当您尝试从jar文件运行应用程序时，会导致Windows上的类加载出现问题。我建议回到1.1.1直到它被修复。

I am folowing the examples about spring boot project. I have compiled and created a jar file via maven but having an error while running attempt.

解决方案

There's a bug in Spring Boot 1.1.2 that causes some problems with class loading on Windows when you try to run your app from a jar file. I'd recommend dropping back to 1.1.1 until it's fixed.
