In the docker-compose.yml file, we define a service called “app” which uses the Dockerfile we created earlier. We set the SPRING_PROFILES_ACTIVE environment variable to “dev” using the environment section. We also map the container’s port 8080 to the host’s port 8080 so that we ca...

比方说,在Linux环境下,设置了环境变量VARIABLE_NAME,那么它也会因为systemEnvironment被Environment管理,可以直接通过第二章介绍的方式获取该值。 export VARIABLE_NAME="value" public class StandardEnvironment extends AbstractEnvironment { public static final String SYSTEM_ENVIRONMENT_PROPERTY_SOURCE_NAME = "systemEn...

Setting environment variable of SPRING_PROFILES_ACTIVE=dev in the Run/Debug Configuration of gradle's [bootRun] task gets the job done in successfully setting the active profile. With the following section in build.gradle bootRun { systemProperties = System.properties ...
系统环境变量可以通过spring.environment属性或直接在application.properties/application.yml中使用通配符${VARIABLE_NAME}来读取。例如,如果你想通过环境变量来设置应用的端口,可以在application.yml中这样配置: server:port:${PORT:8080} 这里${PORT:8080}表示如果环境变量PORT被定义,其值将被用作服务器端口;如果未定义...
