我正在将我的一个微服务迁移到Spring Boot 2.0.0.M6,并且在命令行上使用–spring.config.location =选项时出现错误.错误如下:

如果我不使用自定义属性文件,一切都按预期工作或使用RELEASE版本.我正在使用以下命令启动应用程序:
java -jar application.jar –spring.config.location = app.properties
更新
我注意到当使用这个选项时,Spring完全替换了项目中的默认application.properties,不同于以前只是覆盖参数文件中的属性的Spring版本.这是一个错误吗?
更新2
从团队中获得了response,显然这是预期的行为.试着现在知道是否有办法使用旧版本的行为.
最佳答案
正如Spring团队所说,使用spring.config.location中的旧行为的正确方法是使用新的spring.config.additional-location
