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
