自定义注解

  • com.xkcoding.concurrentinaction.annotation.Recommend 用于标记【推荐】的类
  • com.xkcoding.concurrentinaction.annotation.UnRecommend 用于标记【不推荐】的类
  • com.xkcoding.concurrentinaction.annotation.ThreadSafe 用于标记线程【安全】的类
  • com.xkcoding.concurrentinaction.annotation.ThreadUnSafe 用于标记线程【不安全】的类

并发测试类

需要进行并发安全测试的类,可以直接继承 com.xkcoding.concurrentinaction.base.AbstractConcurrentTest 这个类,重写 AbstractConcurrentTest#testMethod() 这个方法,在里面运行调用待测试的方法,然后执行 AbstractConcurrentTest#execute() 即可开始并发测试。

示例 demo:

package com.xkcoding.concurrentinaction.notsafe;

import com.xkcoding.concurrentinaction.annotation.ThreadUnSafe;
import com.xkcoding.concurrentinaction.base.AbstractConcurrentTest;
import lombok.extern.slf4j.Slf4j;

@ThreadUnSafe

public class ConcurrentIntAdd extends AbstractConcurrentTest {

	private int count = 0;

	public static void main(String[] args) throws Exception {
		ConcurrentIntAdd test = new ConcurrentIntAdd();
		// 执行测试方法
		test.execute();
		log.info("count:{}", test.count);
	}

	private void add() {
		count++;
	}

	/**
	 * 测试方法
	 */
	@Override
	public void testMethod() {
		add();
	}
}
