引言

依照领导要求区分了两种压测模式：固定次数压测和固定时间压测。此前一直沿用的都是固定次数，所以本次第二版剥离了固定次数的模式增加了固定时间的模式。

这是第一版：性能测试框架

第二版的threadbase代码如下

package com.fun.base.constaint;
import com.fun.frame.SourceCode;
import java.util.concurrent.CountDownLatch;

public abstract class ThreadBase<T> extends SourceCode implements Runnable {
    
    CountDownLatch countDownLatch;
    
    public T t;
    protected ThreadBase() {
        super();
    }
    
    public String getT() {
        return t.toString();
    }
    
    protected abstract void before();
    
    protected abstract void doing() throws Exception;
    
    protected abstract void after();
    public void setCountDownLatch(CountDownLatch countDownLatch) {
        this.countDownLatch = countDownLatch;
    }
}

固定次数模式的压测虚拟类

package com.fun.base.constaint;
import com.fun.frame.excute.Concurrent;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.util.ArrayList;
import java.util.List;
import static com.fun.utils.Time.getTimeStamp;

public abstract class ThreadLimitTimes<T> extends ThreadBase {
    private static final Logger logger = LoggerFactory.getLogger(ThreadLimitTimes.class);
    
    public int times;
    
    public T t;
    public ThreadLimitTimes(T t, int times) {
        this(times);
        this.t = t;
    }
    public ThreadLimitTimes(int times) {
        this();
        this.times = times;
    }
    protected ThreadLimitTimes() {
        super();
    }
    
    public String getT() {
        return t.toString();
    }
    @Override
    public void run() {
        try {
            before();
            List<Long> t = new ArrayList<>();
            long ss = getTimeStamp();
            for (int i = 0; i < times; i++) {
                long s = getTimeStamp();
                doing();
                long e = getTimeStamp();
                t.add(e - s);
            }
            long ee = getTimeStamp();
            logger.info("执行次数：{}，总耗时：{}", times, ee - ss);
            Concurrent.allTimes.addAll(t);
        } catch (Exception e) {
            logger.warn("执行任务失败！", e);
        } finally {
            if (countDownLatch != null)
                countDownLatch.countDown();
            after();
        }
    }
    
    protected abstract void before();
    
    protected abstract void doing() throws Exception;
    
    protected abstract void after();
}

固定时间模式虚拟类

package com.fun.base.constaint;
import com.fun.frame.excute.Concurrent;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.util.ArrayList;
import java.util.List;
import static com.fun.utils.Time.getTimeStamp;

public abstract class ThreadLimitTime<T> extends ThreadBase {
    
    private static boolean key = false;
    private static final Logger logger = LoggerFactory.getLogger(ThreadLimitTime.class);
    
    public int time;
    
    public T t;
    public ThreadLimitTime(T t, int time) {
        this(time);
        this.t = t;
    }
    public ThreadLimitTime(int time) {
        this();
        this.time = time * 1000;
    }
    protected ThreadLimitTime() {
        super();
    }
    @Override
    public void run() {
        try {
            before();
            List<Long> t = new ArrayList<>();
            long ss = getTimeStamp();
            while (true) {
                long s = getTimeStamp();
                doing();
                long e = getTimeStamp();
                t.add(e - s);
                if ((e - ss) > time || key) break;
            }
            long ee = getTimeStamp();
            logger.info("执行时间：{} s，总耗时：{}", time / 1000, ee - ss);
            Concurrent.allTimes.addAll(t);
        } catch (Exception e) {
            logger.warn("执行任务失败！", e);
        } finally {
            if (countDownLatch != null)
                countDownLatch.countDown();
            after();
        }
    }
    
    public static void stopAllThread() {
        key = true;
    }
}

这里我多加了一个终止测试的key，暂时没有用，以防万一。之所以没有采用另起线程去计时原因有二：进行测试过程中无论如何都会记录时间戳，多余的计算比较时间戳大小消耗性能很低，可以忽略；另起线程设计麻烦，在发生意外情况时缺少第二种保险措施。

HTTPrequestbase为基础的多线程类

下面是两种实现类的Demo，以HTTPrequestbase作为基础的多线程类。

固定次数模式的多线程类


public class RequestThreadTimes extends ThreadLimitTimes {
    static Logger logger = LoggerFactory.getLogger(RequestThreadTimes.class);
    
    public HttpRequestBase request;
    
    public RequestThreadTimes(HttpRequestBase request, int times) {
        this.request = request;
        this.times = times;
    }
    @Override
    public void before() {
        GCThread.starts();
    }
    @Override
    protected void doing() throws Exception {
        getResponse(request);
    }
    @Override
    protected void after() {
        GCThread.stop();
    }
    
    void getResponse(HttpRequestBase request) throws IOException {
        CloseableHttpResponse response = ClientManage.httpsClient.execute(request);
        String content = FanLibrary.getContent(response);
        if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK)
            logger.warn("响应状态码：{},响应内容：{}", content, response.getStatusLine());
        response.close();
    }
}

固定时间模式的多线程类


package com.fun.frame.thead;
import com.fun.base.constaint.ThreadLimitTime;
import com.fun.frame.httpclient.ClientManage;
import com.fun.frame.httpclient.FanLibrary;
import com.fun.frame.httpclient.GCThread;
import org.apache.http.HttpStatus;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpRequestBase;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.IOException;

public class RequestThreadTime extends ThreadLimitTime {
    static Logger logger = LoggerFactory.getLogger(RequestThreadTime.class);
    
    public HttpRequestBase request;
    
    public RequestThreadTime(HttpRequestBase request, int time) {
        this.request = request;
        this.time = time;
    }
    @Override
    public void before() {
        GCThread.starts();
    }
    @Override
    protected void doing() throws Exception {
        getResponse(request);
    }
    @Override
    protected void after() {
        GCThread.stop();
    }
    
    void getResponse(HttpRequestBase request) throws IOException {
        CloseableHttpResponse response = ClientManage.httpsClient.execute(request);
        String content = FanLibrary.getContent(response);
        if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK)
            logger.warn("响应状态码：{},响应内容：{}", content, response.getStatusLine());
        response.close();
    }
}

其中可以发现，差别就在于属性time还是times的设定。

使用Demo：

package com.fun;
import com.fun.base.constaint.ThreadLimitTime;
import com.fun.frame.SourceCode;
import com.fun.frame.excute.Concurrent;
import java.util.ArrayList;
import java.util.List;
public class AR extends SourceCode {
    public static void main(String[] args) {
        ThreadLimitTime<Object> threadLimitTime = new ThreadLimitTime<Object>(10) {
            
            @Override
            protected void before() {
            }
            
            @Override
            protected void doing() throws Exception {
                AR.test();
            }
            
            @Override
            protected void after() {
            }
        };
        new Concurrent(threadLimitTime,5).start();
        FanLibrary.testOver();
    }
    public static void test() {
        synchronized (AR.class) {
            sleep(100);
            output("fun");
        }
    }
}

剩下的mysql和redis以及dubbo的Demo就不写了，各位看官看着发挥即可，更多关于java性能测试框架的资料请关注编程网其它相关文章！
