问题描述
我们的操作人员希望在应用启动时将Spring引导配置（即所有属性）转储到日志文件中。我认为可以通过使用注解@ConfigurationProperties注入属性并打印它们来完成此操作。
Our Ops guys want the Spring boot configuration (i.e. all properties) to be dumped to the log file when the app starts. I assume this can be done by injecting the properties with annotation @ConfigurationProperties and printing them.
问题是是否有更好的或内置的机制来实现这一目标。
The questions is whether there is a better or built-in mechanism to achieve this.
鉴于似乎没有内置的解决方案，我尝试自己做饭。这是我想出的：
Given there does not seem to be a built in solution besides, I was try to cook my own. Here is what I came up with:
@Component
public class ConfigurationDumper {
@Autowired
public void init(Environment env){
log.info("{}",env);
}
}
挑战是它不打印我的application.yml中的变量。相反，这是我得到的：
The challenge with this is that it does not print variables that are in my application.yml. Instead, here is what I get:
StandardServletEnvironment
{
activeProfiles=[],
defaultProfiles=[default],
propertySources=[
servletConfigInitParams,
servletContextInitParams,
systemProperties,
systemEnvironment,
random,
applicationConfig: [classpath: /application.yml]
]
}
我该如何要解决此问题，以便加载和打印所有属性？
How can I fix this so as to have all properties loaded and printed?
推荐答案
如果使用， env 端点将为您提供所有在 ConfigurableEnvironment 和 configprops 中设置的配置属性将为您提供 @ConfigurationProperties ，但不在日志中。
If you use actuator , env endpoint will give you all the configuration properties set in ConfigurableEnvironment and configprops will give you the list of @ConfigurationProperties, but not in the log.
看看，也许是它将使您了解如何获取所有感兴趣的属性。
Take a look at the source code for this env endpoint, may be it will give you an idea of how you could get all the properties you are interested in.
