'application.properties'應該位於src \ main \ resources'文件夾中 –

您錯過的application.properties文件。使用Spring Boot，您可以將此文件放置在與jar文件相同的級別，並使用該文件。查看文檔以獲得更多信息link here

但是spring會在classpath中搜索屬性文件springframework.core.io.ClassPathResource.getInputStream（ClassPathResource.java:172）。而application.properties文件位於jar文件中意味着它在classpath/ –

有一個bug in Spring Boot 1.1.2，當您嘗試從jar文件運行您的應用程序時，會在Windows上導致類加載問題。我建議回到1.1.1直到它被修復。
