java - 如何获取已应用的 Spring Boot (auto) 配置列表

Question

如何获取已应用的 Spring Boot(自动或非自动)配置列表？

Answer 1

构建工件后，如果启动它并包含 --debug 命令参数，您可以获得自动配置报告:

java -jar artifact.jar --debug

或者直接将其添加为SpringApplication.run()的参数

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

或在 IDE 内部，通过将 --debug 添加为启动配置中的参数。

报告将如下所示:
