学习SpringBoot配置应用名称，结果发现坑
到网上找 到
https://blog.csdn.net/qq_40087415/article/details/82497668
server:
port:8088
context-path:/springboot-demo
实际，在我的SpringBoot 的 2.2.2.RELEASE 中，是编译不通过的；
而我后来实践发现：
YAML中配置应用名称
server:
port: 8082
servlet:
context-path: /study
编译通过，日志如下
2020-01-02 22:23:28.851 INFO 5532 --- [ main] o.apache.catalina.core.StandardService : Starting service [Tomcat]
2020-01-02 22:23:28.851 INFO 5532 --- [ main] org.apache.catalina.core.StandardEngine : Starting Servlet engine: [Apache Tomcat/9.0.29]
2020-01-02 22:23:28.991 INFO 5532 --- [ main] o.a.c.c.C.[Tomcat].[localhost].[/study] : Initializing Spring embedded WebApplicationContext

所以估计是SpringBoot版本导致的不一样
