Java Spring boot未加载特定配置文件

我无法从命令行加载特定的Spring启动配置文件

applciation.yml文件内容如下，它位于我的应用程序的资源文件夹中

server:
    port: 8787
spring:
  application:
    name: demo

spring:
  profiles: local_mysql
  datasource:
    url: jdbc:mysql://localhost:3306/demo?createDatabaseIfNotExist=true
    username: root
    password: root
    driverClassName: com.mysql.jdbc.Driver
  jpa:
    hibernate:
      ddl-auto: update
      dialect: org.hibernate.dialect.MySQLDialect
server:
    port: 8787

spring:
  profiles: development
  datasource:
    url: jdbc:mysql://localhost:3306/demo?createDatabaseIfNotExist=true
    username: admin
    password: admin
    driverClassName: com.mysql.jdbc.Driver
  jpa:
    hibernate:
      ddl-auto: update
      dialect: org.hibernate.dialect.MySQLDialect
server:
    port: 8788

java -jar -Dspring.profiles.active=local_mysql target\demo-1.0.0-SNAPSHOT.jar

执行

mvn清洁包后

并使用

java-jar-Dspring.profiles.active=local\u mysql target\demo-1.0.0-SNAPSHOT.jar

---

应用程序忽略指定的配置文件，只在8080上启动H2 Db而不是mySQL。

创建名为

Application-local\u mySQL.yml

的单独文件，并在该文件中具有

local\u mySQL

相关设置。对所有配置文件执行相同的操作。在

application.yml

中，所有配置文件都有相同的配置

文件应位于

$CLASSPATH\config\

位置

然后运行应用程序

server:
    port: 8787
spring:
  application:
    name: demo

spring:
  profiles: local_mysql
  datasource:
    url: jdbc:mysql://localhost:3306/demo?createDatabaseIfNotExist=true
    username: root
    password: root
    driverClassName: com.mysql.jdbc.Driver
  jpa:
    hibernate:
      ddl-auto: update
      dialect: org.hibernate.dialect.MySQLDialect
server:
    port: 8787

spring:
  profiles: development
  datasource:
    url: jdbc:mysql://localhost:3306/demo?createDatabaseIfNotExist=true
    username: admin
    password: admin
    driverClassName: com.mysql.jdbc.Driver
  jpa:
    hibernate:
      ddl-auto: update
      dialect: org.hibernate.dialect.MySQLDialect
server:
    port: 8788

java -jar -Dspring.profiles.active=local_mysql target\demo-1.0.0-SNAPSHOT.jar

参考：

在我看来，最好为不同的配置文件创建多个yml文件（如@karthikeyan vaithilingam post中所述），但仅供注意-您可以在application.yml中拥有多个配置文件的属性-这里是eureka用法示例：

---
spring:
  profiles: peer1
eureka:
  instance:
    hostname: peer1
    metadataMap:
      # Each eureka instance need unique id. By default its hostname so we would have to use 1 server per service
      instanceId: PEER1_${spring.application.name}:${spring.application.instance_id:${random.value}}
---
spring:
  profiles: peer2
eureka:
  instance:
    hostname: peer2
    metadataMap:
  # Each eureka instance need unique id. By default its hostname so we would have to use 1 server per service
      instanceId: PEER2_${spring.application.name}:${spring.application.instance_id:${random.value}}
