如何獲取應用的Spring Boot（自動）配置列表

Question

如何獲取應用的Spring Boot（自動或非自動）配置的列表？

Answer 1

你得到你的神器建成後，你可以，如果你啓動它包括--debug命令參數得到一個自動配置報告：

java -jar artifact.jar --debug 

或直接將其作爲SpringApplication.run參數（）

SpringApplication.run(WebApp.class, "--debug"); 

或者在IDE內部，通過在啓動配置中添加--debug作爲參數。

報告將是這樣的：

AUTO-CONFIGURATION REPORT

Spring Boot Actuator能夠轉儲此類信息。

http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-external-config-validation

啓用致動器，然後打開http://localhost/configprops。 這裏是我的一個項目爲例：

器顯示了很多有用的信息（自動配置，ENV，映射，豆類，日誌文件，跟蹤和更多），所以我建議你甚至啓用一臺生產機器。它可以很容易地通過密碼進行保護。

要查看來自application.properties/application.yml的配置，您可以使用端點/env。
