如何通过Spring Boot管理控制台更改属性值？

Question

我有一个Spring Boot管理控制台的Spring启动应用程序：

它显示Details，Metrics等。还有一个Environment标签。

1. 是否可以通过Environment选项卡更改application.properties值？
2. 如果我向属性键添加新值并按Update environment按钮，则应用程序中没有任何更改。为什么？我需要做任何额外的设置吗？

谢谢。

我对POM的依赖：

Answer 1

我已经设置了一些测试环境...

使用SBA，我更新了一个环境。.一个小的hello-world REST端点显示了新值...但是在SBA中是旧值。

也许您的bean需要一个@RefreshScope批注？
