问题描述
我的Spring Boot应用程序以3种配置运行:
My Spring Boot application runs with 3 configurations:
- application.properties->用于开发环境
- application-test.properties->用于测试环境
- application-production.properties->用于生产环境
如何在百里香环境中运行应用程序?
How is it possible to get in thymeleaf environment the application is running?
我只需要在生产环境中包括Google Analytics(分析)代码.
I need to include the Google Analytics code only in production environment.
推荐答案
如果一次只有一个配置文件处于活动状态，则可以执行以下操作.
You can do the following if you only have one profile active at a time.
<div th:if="${@environment.getActiveProfiles()[0] == 'production'}">
This is the production profile - do whatever you want in here
</div>
以上代码基于Thymeleaf的Spring方言允许您使用@符号访问bean的事实.当然，Environment对象始终可以作为Spring bean使用.
The code above is based on the fact that the Thymeleaf's Spring dialect lets you access beans using the @ symbol. And of course the Environment object is always available as a Spring bean.
还请注意，Environment具有方法getActiveProfiles()，该方法返回一个字符串数组(这就是为什么在我的答案中使用[0]的原因)，我们可以使用标准Spring EL进行调用.
Also note that Environment has the method getActiveProfiles() which returns an array of Strings (that is why [0] is used in my answer) which we can call using standard Spring EL.
如果一次有多个配置文件处于活动状态，则更可靠的解决方案是使用Thymeleaf的#arrays实用程序对象，以检查活动配置文件中是否存在字符串production.在这种情况下，代码将是:
If more than one profiles are active at a time, a more robust solution would be to use Thymeleaf's #arrays utility object in order to check for the presence of the string production in the active profiles. The code in that case would be:
<div th:if="${#arrays.contains(@environment.getActiveProfiles(),'production')}">
This is the production profile
</div>
