Here is a more complete example.

Autowire Environment

First you will want to autowire the environment bean.

<pre><code>@Autowired
private Environment environment;
</code></pre>

Check if Profiles exist in Active Profiles

Then you can use <code>getActiveProfiles()</code> to find out if the profile exists in the list of active profiles. Here is an example that takes the <code>String[]</code> from <code>getActiveProfiles()</code>, gets a stream from that array, then uses matchers to check for multiple profiles(Case-Insensitive) which returns a boolean if they exist.

<pre><code>//Check if Active profiles contains "local" or "test"
if(Arrays.stream(environment.getActiveProfiles()).anyMatch(
 env -&gt; (env.equalsIgnoreCase("test") 
 || env.equalsIgnoreCase("local")) )) 
{
 doSomethingForLocalOrTest();
}
//Check if Active profiles contains "prod"
else if(Arrays.stream(environment.getActiveProfiles()).anyMatch(
 env -&gt; (env.equalsIgnoreCase("prod")) )) 
{
 doSomethingForProd();
}
</code></pre>

You can also achieve similar functionality using the annotation <code>@Profile("local")</code> Profiles allow for selective configuration based on a passed-in or environment parameter. Here is more information on this technique: <a href="https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-profiles.html" rel="noreferrer">Spring Profiles</a>

It works and you don't need to implement EnvironmentAware. But I don't know drawbacks of this approach.

Extending User1648825's nice simple answer:
<pre><code>@Value(&quot;${spring.profiles.active}&quot;)
private String activeProfile;
</code></pre>
This may throw an IllegalArgumentException if no profiles are set (I get a null value). This may be a Good Thing if you need it to be set; if not use the 'default' syntax for @Value, ie:
<pre><code>@Value(&quot;${spring.profiles.active:Unknown}&quot;)
private String activeProfile;
</code></pre>
...activeProfile now contains 'Unknown' if spring.profiles.active could not be resolved

Seems there is some demand to be able to access this statically.

It's a hack, but you can write your own class to expose it. You must be careful to ensure that nothing will call <code>SpringContext.getEnvironment()</code> before all beans have been created, since there is no guarantee when this component will be instantiated.

<pre><code>@Component
public class SpringContext
{
 private static Environment environment;

 public SpringContext(Environment environment) {
 SpringContext.environment = environment;
 }

 public static Environment getEnvironment() {
 if (environment == null) {
 throw new RuntimeException("Environment has not been set yet");
 }
 return environment;
 }
}
</code></pre>

As already mentioned earlier. You could autowire Environment:
<pre><code>@Autowired
private Environment environment;
</code></pre>
only you could do check for the needed environment much easier:
<pre><code>if (environment.acceptsProfiles(Profiles.of(&quot;test&quot;))) {
 doStuffForTestEnv();
} else {
 doStuffForOtherProfiles();
}
</code></pre>

blocks|key|238839|text|如果你既不想使用@Autowire，也不想注入@Value，你可以简单地这样做(包括回退)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|238840|System.getProperty("spring.profiles.active",+"unknown");|code-block|syntax|javascript|238841|这将返回任何活动的配置文件(或回退到“未知”)。|238842|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

And if you neither want to use @Autowire nor injecting @Value you can simply do (with fallback included):
<pre><code>System.getProperty(&quot;spring.profiles.active&quot;, &quot;unknown&quot;);
</code></pre>
This will return any active profile (or fallback to 'unknown').

I need to code different logic based on different current Environment profile.
How can you get the currently active and default profiles from Spring?

How do you get current active/default Environment profile programmatically in Spring?

我需要编码不同的逻辑基于不同的当前环境配置文件。如何从获取当前活动的和默认的配置文件？
