bootstrap.yml 未加载 Spring 启动 2
bootstrap.yml not loading for Spring Boot 2
我遇到了与此类似的问题 thread（尚未解决）。
我有一个 Spring Boot 2 应用程序和一个 bootstrap.yml 文件。有一个 属性 "spring.data.cassandra.keyspace-name" 没有被拾取。我在src/main/resources下只有一个bootstrap.yml。
重要说明：如果我将 bootstrap.yml 重命名为 application.yml，一切正常。
这看起来像是一个真正的错误。有人可以确认他们也面临这个问题吗？还是我做错了什么？
bootstrap.yml内容如下：
spring:
profiles: default
# Pretty-print JSON responses
jackson:
serialization:
indent-output: true
data:
cassandra:
contact-points: localhost
keyspace-name: samplekeyspace

仅当您使用任何 Spring Cloud Starter 模块时才使用 bootstrap.yml（或 .properties）文件。这用于指定 spring 云配置服务器位置，用于引导最小应用程序上下文，该上下文将从配置服务器收集应用程序属性，然后创建具有这些属性的子上下文以启动实际应用程序。
如果您不使用 Spring 云配置功能，则方法是为您的应用程序使用 application.yml 或 .properties 文件。
