获取@PropertySource 加载的文件名 [英] get name of the file loaded by @PropertySource

问题描述

无论如何我可以在我的程序中知道通过Spring的@PropertySource注释加载的文件的完整路径.我需要它显示在日志中，以便人们可以知道应用程序中正在使用哪个属性文件

Is there anyway I can know in my program, the full path of file loaded through @PropertySource annotation of Spring. I need it to show in logs so that one can know which property file is being used in the application

推荐答案

以下似乎有效，但我不确定该实例是否始终为 ConfigurableEnvironment

Below seems to be working, though I am not sure if the instance is always of type ConfigurableEnvironment

@Component
public class MyListener implements ApplicationListener<ContextRefreshedEvent>{

  @Autowired
  private Environment env;

  private static final Logger log = LoggerFactory.getLogger(MyListener.class);

  @Override
  public void onApplicationEvent(ContextRefreshedEvent event) {

    if(env instanceof ConfigurableEnvironment){
      MutablePropertySources propertySources = ((ConfigurableEnvironment)env).getPropertySources();
      for(PropertySource ps : propertySources){
        log.info(ps.getName());  //if only file based needed then check if instanceof ResourcePropertySource
      }
    }
  }
}

真的不需要这一切.正如塞利姆已经回答的那样，启用正确的日志可以解决问题

don't really need all this. As already answered by Selim, enabling the proper logs does the trick

log4j.logger.org.springframework.core.env.MutablePropertySources=DEBUG
