学习高并发使用的工具

遇到以下问题：

按照百度上面的流程，直接移植到springboot项目中测试，发现每次install都会报错

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.2:test (default-test) on project demo1: There are test failures.

无法生成jcstress.jar包，继而无法测试

解决方案：

重新创建一个新的maven项目

测试类

package com.hikktn;

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

@JCStressTest
@State
//             r1  r2
@Outcome(id = "1, 0", expect = Expect.ACCEPTABLE)
@Outcome(id = "0, 2", expect = Expect.ACCEPTABLE)
@Outcome(id = "1, 2", expect = Expect.ACCEPTABLE)
@Outcome(id = "0, 0", expect = Expect.ACCEPTABLE_INTERESTING)
public class Test4Possible {
    int a;
    int b;
    @Actor
    public void action1(II_Result r) {
        a = 1;
        r.r2 = b;
    }
    @Actor
    public void action2(II_Result r) {
        b = 2;
        r.r1 = a;
    }
}

项目结构 

操作 

注意点

每次新建测试类，需要重新clean后，再次install。执行成功后，执行  java -jar target/jcstress.jar

效果如下
