2、Java 压测脚本
2.1、被压测代码
@Slf4j
public class JmeterServer {
public String yc(){
for (int i = 0 ; i< 100000; i++){
try {
log.info("[JmeterServer#yc] start ");
Thread.sleep(1000L);
log.info("[JmeterServer#yc] end ");
} catch (InterruptedException e) {
e.printStackTrace();
}
}
return Thread.currentThread().getName();
}
@Test
public void test(){
yc();
}
}
2.2、压测脚本
继承
AbstractJavaSamplerClient：
@Slf4j
public class JavaClient extends AbstractJavaSamplerClient {
/**
* 把测试的一些默认数据在程序运行前显示到JMeter客户端
*/
@Override
public Arguments getDefaultParameters() {
Arguments params = new Arguments();
params.addArgument("num1", "num1");
params.addArgument("num2", "num2");
return params;
}
/**
* 子类用它来 记录log
*
* @return
*/
@Override
protected org.apache.log.Logger getLogger() {
return null;
}
/**
* 初始化方法，实际运行时每个线程仅执行一次，在测试方法运行前执行
*
* @param context
*/
@Override
public void setupTest(JavaSamplerContext context) {
String num1 = context.getParameter("num1");
String num2 = context.getParameter("num2");
log.info("[JavaClient#setupTest] num1:{}, num2:{}", num1, num2);
}
/**
* 结束方法，实际运行时每个线程仅执行一次，在测试方法运行结束后执行
*/
@Override
public void teardownTest(JavaSamplerContext context) {
String num1 = context.getParameter("num1");
String num2 = context.getParameter("num2");
log.info("[JavaClient#teardownTest] num1:{}, num2:{}", num1, num2);
}
/**
* @Test只是为了调试用，最后打jar包的时候注释掉。
*/
@Test
public void test() {
}
public static void main(String[] args) {
//设置参数，并赋予默认值2
Arguments params = new Arguments();
params.addArgument("num1", "1");
params.addArgument("num2", "2");
JavaSamplerContext arg0 = new JavaSamplerContext(params);
JavaClient test = new JavaClient();
test.setupTest(arg0);
test.runTest(arg0);
test.teardownTest(arg0);
}
/**
* 测试执行的循环体，根据线程数和循环次数的不同可执行多次
* 1、获取界面中传递的值
* 2、压测结果获取
* 3、判断测试成功与否的方法：可根据实际进行判断，此处为如果结果非空，则认为该次调用成功
*
* @param context
* @return
*/
@Override
public SampleResult runTest(JavaSamplerContext context) {
SampleResult sampleresult = new SampleResult();
// 1、获取界面中传递的值
String num1 = context.getParameter("num1");
String num2 = context.getParameter("num2");
sampleresult.sampleStart();//计时开始
try {
// 2、压测结果获取
JmeterServer test = new JmeterServer();
String result = test.yc();
//将结果写入结果树：在jmeter的监听器-查看结果树时即可查看返回结果
sampleresult.setResponseData("结果是：" + result + "," + num1 + "," + num2, null);
sampleresult.setDataType(SampleResult.TEXT);
sampleresult.setSuccessful(true);
} catch (Exception e) {
//不满足判断条件则判为false，会出现在监听器-聚合报告的Error%列
sampleresult.setSuccessful(false);
e.printStackTrace();
} finally {
//计时结束
sampleresult.sampleEnd();
}
// 3、判断测试成功与否的方法：可根据实际进行判断，此处为如果结果非空，则认为该次调用成功
// if (result.equals("a")) {
// //将结果写入结果树：在jmeter的监听器-查看结果树时即可查看返回结果
// sampleresult.setSuccessful( true);
// sampleresult.setResponseData( "结果是："+a ,null);
// sampleresult.setDataType(SampleResult. TEXT);
// } else {
// sampleresult.setSuccessful( false);//不满足判断条件则判为false，会出现在监听器-聚合报告的Error%列
// }
return sampleresult;
}
}
3、maven 打包
1、使用
maven，把项目打包成hlj_Jmeter.jar和lib目录（依赖的各种jar）2、将
MyTest.jar和lib目录拷贝到jmeter的JMETER_HOME\lib\ext目录（
4、压测
4.1、压测操作
4.1.1、创建线程组
4.1.2、Java 请求
4.1.3、查看结果树
4.2、执行压测
4.2.1、点击开始
4.2.2、查看压测结果
