java - Bean创建异常: Error creating bean with name servletContainer

Question

我使用一个可以正确构建的 Spring Boot 项目。但是，在使用命令运行项目时，例如mvn spring-boot:run 我收到以下错误堆栈，其中包含下面提供的 BeanCreationException，

2017-12-04 17:07:03.210 ERROR 2764 --- [           main] o.s.boot.SpringApplication               : Application startup failed

问题似乎是从 keystore-folder: ${BASE} 行和错误堆栈的相关部分开始的，

Factory method 'servletContainer' threw exception; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'BASE' in value "${BASE}"

你知道如何解决这个问题吗？

Answer 1

我显然应该提供一个名为BASE的 key 。您可以引用this
