springBoot 项目在项目启动时修改dev或prod文件（在远程拉取的值）

在启动类中加
public static void main(String[] args) throws UnknownHostException {
   SpringApplication app = new SpringApplication(CtginmsPortalApplication.class);

   app.addInitializers(new ZkApplicationContextInitializer());//这点

    System.out.println(env.getProperty("spring.datasource.url"));//打印看看

}
重新创建的类

public class ZkApplicationContextInitializer implements ApplicationContextInitializer {

    @Override
    public void initialize(ConfigurableApplicationContext applicationContext) {

        ConfigurableEnvironment ce = applicationContext.getEnvironment();
            Properties properties = new Properties();
            properties.setProperty("spring.datasource.url", "url000");//前面时dev或prod的key，后面时远程拉取下来的值
            properties.setProperty("spring.datasource.driver-class-name", "name111");
     
            PropertiesPropertySource propertiesPropertySource = new PropertiesPropertySource("remote", properties);
            ce.getPropertySources().addFirst(propertiesPropertySource);
    }
}
