您可以使用
spring.config.name以下方法实现第一个建议：
public static void main(String[] args) { SpringApplicationBuilder parentBuilder = new SpringApplicationBuilder(ParentApplication.class) .web(WebApplicationType.NONE); parentBuilder.run(args); parentBuilder.child(ServiceOneConfiguration.class) .properties("spring.config.name=child1").run(args); parentBuilder.child(ServiceTwoConfiguration.class) .properties("spring.config.name=child2").run(args);}然后
child1{-profile}.properties，您可以分别使用和child2{-profile}.properties配置服务一和服务二。例如，使用
server.port=8081in
child1.properties和
server.port=8082in
child2.properties，在两个子服务中启动使用自动配置的应用程序时，您应该看到类似于以下内容的输出
