SpringBoot集成JMH进行基准测试2 - 你不知道的浪漫

公告

SpringBoot集成JMH进行基准测试2

接上篇：SpringBoot集成JMH进行基准测试

本地环境：IDEA 2018.3.6

jmh 1.21 。本地使用1.22失败，可能是windows 10下面使用了阿里巴巴的Maven镜像源有bug

上一篇算是一次失败的尝试，后来笔者又查阅了别人的文章,分享一个可用的

运行方法：

右键 AppTest.java，选择run

REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
experiments, perform baseline and negative tests that provide experimental control, make sure
the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
Do not assume the numbers tell you what you want them to tell.
