    <artifactId>jmh-core</artifactId>
    <version>1.36</version>
</dependency>

<dependency>
    <groupId>org.openjdk.jmh</groupId>
    <artifactId>jmh-generator-annprocess</artifactId>
    <version>1.36</version>
    <scope>test</scope>
</dependency>

2.IDEA 

JMH Plugin

由于用到了注解，运行程序注解配置

setting -> Build,Execution,deployment -> Complier -> Annotation Processors -> Enable annotation processing 勾上

3. 测试类要在 test package 下面

4. 如果报错: trying to acquire the JMH lock c:\windows\/jmh.lock 拒绝访问.

RunConfiguration -> Environment Variables -> include system environment viables
