如何使用d簧护套2和千分尺测量维修方法

如何使用d簧护套2和千分尺测量维修方法

这是一个小样本，应该可以帮助您。这里

Timer.record()

没有显示更多的变体。（此外：字段注入仅出于简洁目的。）您不必将调用的方法名称放入标签中。您也可以使其成为度量标准名称本身的一部分。只是想展示您可以做什么。

更新2018年3月12日： 中作为

Micrometer1.0.0

一个

TimedAspect

已经出台，让你也可以使用

@Timed

注解。现在，您需要注册

Bean

自己。（尽管在

@Timed

Spring-MVC或Jersey资源上具有自定义注释时，您必须要谨慎。）[MichalStepan]在后续回答中已经提到了这一点。

如果您选择普罗米修斯，您最终会得到类似的东西：
