1.创建maven项目

通过mvn archetype:generate这种交互方式来创建Maven项目。

mvn archetype:generate  -DinteractiveMode=false -DarchetypeGroupId=org.openjdk.jcstress -DarchetypeArtifactId=jcstress-java-test-archetype -DarchetypeVersion=0.5 -DgroupId=exam.offer -DartifactId=testJcstress -Dversion=1.0

pom.xml文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>exam.offer</groupId>
    <artifactId>testJcstress</artifactId>

    <packaging>jar</packaging>

    <name>JCStress test sample</name>

2.导入

打开Project Structure,然后找到Modules,导入

注意选择的是pom.xml,如图所示。


3.编写测试文件

按自己的需求写就可以了,为了方便展示待会咋运行,写一个例子,这个例子是用来测试指令重排序的。

import org.openjdk.jcstress.annotations.*;
import org.openjdk.jcstress.infra.results.II_Result;

// See jcstress-samples or existing tests for API introduction and testing guidelines

@JCStressTest
//表示有可能会出现的结果,其中0是我们感兴趣的结果
@Outcome(id="0",expect = Expect.ACCEPTABLE_INTERESTING,desc="!!!!")
@Outcome(id = "1, 4", expect = Expect.ACCEPTABLE, desc = "ok")
@State
public class ConcurrencyTest {

    int num=0;
    boolean ready=false;
    @Actor
    public void actor1(II_Result r) {
        // Put the code for first thread here
        if(ready){
            r.r1=num+num;
        }else{
            r.r1=1;
        }
    }

    @Actor
    public void actor2(II_Result r) {
        // Put the code for second thread here
        num=2;
        ready=true;
    }

}


4.打成jar包

运行的话需要打成jar包,最右侧有一个Maven Projects,然后找到下图所示的package,双击即可。


5.进行并发压力测试

找到target目录并右击,进入Terminal,输入java -jar jcstress.jar


6.结果

target中有一个results文件夹下的index.html可以查看结果,也可以直接看控制台输出的测试结果。
