springboot bootstrap.yml和application.yml和application.properties 加载顺利
springboot bootstrap.yml和application.yml和application.properties 加载顺利
原文地址https://blog.csdn.net/weixin_43931625/article/details/103628375
bootstrap.yml在application.yml之前加载，一般在spring cloud使用配置中心时使用；
bootstrap.yml同名属性会被application.yml覆盖；
application.yml在application.properties之前加载，同名属性会被application.properties覆盖
示例
导入jar包，使bootstrap.yml得配置生效
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-context</artifactId>
<version>2.2.0.RELEASE</version>
</dependency>
bootstrap.yml
server:
port: 8081
启动应用，控制台输出

应用监听端口为8081，bootstrap.yml生效
添加application.yml
server:
port: 8082
启动应用，控制台输出

应用监听端口为8082，application.yml覆盖bootstrap.yml的端口配置
添加application.properties
server.port=8083
启动应用，控制台输出

应用监听端口为8083，application.properties覆盖前面的配置信息
