Springboot项目，多线程测试使用Redis生成订单id

Springboot项目，多线程测试使用Redis生成订单id

springboot测试类：

import org.junit.After;
import org.junit.Before;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;

/**
 * @date 2018/12/5
 * @since 1.0.0
 */
@RunWith(SpringRunner.class)
@SpringBootTest
//@WebAppConfiguration
public class BaseApplicationTests {

    @Before
    public void init() {
        System.out.println("begin the test ...........");
    }

    @After
    public void after() {
        System.out.println("end the test ...........");
    }
}

Redis并使用多线程测试

springboot项目中的redis的配置这里就不在贴上去了。
看测试代码吧：

import org.apache.commons.lang3.time.DateFormatUtils;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;

import java.util.Calendar;
import java.util.Date;
import java.util.concurrent.Executor;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

/**
 * redis生成订单号
 *
 * @date 2018/12/5
 * @since 1.0.0
 */
public class RedisTest extends BaseApplicationTests {

    private static String REDIS_MANAGE_CONTRACT_PREFIX = "yuy:manage:TEST_CONTRACT_INC_";

    @Autowired
    private StringRedisTemplate redisTemplate;

    @Autowired
    private Executor executor;

    public String generateContractNo() {
        //合同编号规则: BNF + 当前日期 + 四位编号，编号每天从1开始递增
        String currentDate = DateFormatUtils.format(new Date(), "yyyyMMdd");
        String key = REDIS_MANAGE_CONTRACT_PREFIX + currentDate;
        long count = redisTemplate.opsForValue().increment(key, 1);
        if (count == 1) {
            redisTemplate.expireAt(key, getTimeout());
        }
        return String.format("BNF%s-%s", currentDate, String.format("%04d", count));
    }

    private Date getTimeout() {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, 23);
        calendar.set(Calendar.MINUTE, 59);
        calendar.set(Calendar.SECOND, 59);
        return calendar.getTime();
    }

    @Test
    public void test1() {
        Runnable task = () -> {
            try {
                System.out.println(Thread.currentThread().getName()+"   订单号:"+generateContractNo());
                Thread.sleep(500);
            } catch (Exception e) {
                System.out.println("task interrupted: " + e);
                e.printStackTrace();
            }
        };
        ExecutorService executorService = Executors.newFixedThreadPool(5);
        try {
            for (int i = 0; i < 10; i++) {
                executorService.execute(task);
            }
            Thread.sleep(1000);// 当前主线程休眠
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            executorService.shutdown();
        }

        /*for (int i = 0; i < 10; i++) {
            executorService.execute(task);
        }
        try {
            executorService.shutdown();
            if (!executorService.awaitTermination(60, TimeUnit.SECONDS)) {
                executorService.shutdownNow();
            }
        } catch (InterruptedException e) {
            System.out.println("awaitTermination interrupted: " + e);
            executorService.shutdownNow();
        }*/

    }
}
