jmeter java请求

1.将写好的java项目导出jar包、和用到的jar，一起放到$apache-jmeter-2.11libext文件夹下：

showpack.jar、httpclient（commons-codec-1.6.jar、commons-httpclient-3.0.jar、commons-logging-1.1.3.jar）

2.sampler-java request，选择jmeter的测试类。

3.具体操作：：：

                                                  

elipse用到的jar：

logkit-2.0.jar、jorphan.jar、avalon-framework-4.1.4.jar、ApacheJMeter_core.jar、ApacheJMeter_java.jar

代码：

package com.httpclient;

import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
import org.apache.jmeter.samplers.SampleResult;

public class Jtest extends AbstractJavaSamplerClient {
    private String grade = "", subject = "";

    public void setupTest(JavaSamplerContext arg0) {
        System.out.println("setupTest");

    }

    public void teardownTest(JavaSamplerContext arg0) {
        System.out.println("teardown");
    }

    public SampleResult runTest(JavaSamplerContext arg0) {
        grade = arg0.getParameter("grade"); // 得到参数
        subject = arg0.getParameter("subject");
        SampleResult sr = new SampleResult(); //创建SampleResult的对象
        sr.setSampleLabel("selectpack"); // 响应名称
        try {
            sr.sampleStart(); // sample开始
            DzPack dz = new DzPack(); // 实例化httpclient的类
            String resultdata = dz.getPack(grade, subject); // 取得httpclient实例化对象的getpack方法返回值
            sr.setDataEncoding("UTF-8"); // 设置响应的编码格式
            sr.setResponseData(resultdata, null); // 设置响应内容
            // System.out.println(resultdata);
            sr.setSuccessful(true); // sample成功
            sr.setResponseCodeOK(); //
            sr.setRequestHeaders("request for :" + " grade is " + grade
                    + " ; " + "subject is " + subject + " ; "); // 设置请求头
        } catch (Throwable e) {
            sr.setSuccessful(false); // 异常时，sample失败
            e.printStackTrace();
        } finally {
            sr.sampleEnd(); // 结束sample
        }
        return sr;
    }

    // 设置默认参数
    public Arguments getDefaultParameters() {
        Arguments params = new Arguments();
        params.addArgument("grade", "1039");
        params.addArgument("subject", "1001");
        return params;
    }

     * JavaSamplerContext arg0 = new JavaSamplerContext(new Arguments());
