小白之jmeter入门(三):自定义Java任务压测

### 针对某些特殊场景,jmeter提供的功能不能满足于需求,这个时候就需要自己编写自定义的java任务进行压测 ###

**一. 自定义java任务**

1.1 重apache-jmeter\\lib\\ext   目下copy   ApacheJMeter\_core.jar和ApacheJMeter\_java.jar到工程目录下

1.2 继承 AbstractJavaSamplerClient类并重写runTest，getDefaultParameters,setupTest方法

package test;
    
    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;
    
    import java.util.HashMap;
    import java.util.Map;
    
    /**
     * @Date 2019/3/19 10:48
     * @Created by LeeJunMing
     */
    public class TestSocket extends AbstractJavaSamplerClient {
        private static final String HOST_NAME = "HOST";//设置GUI页面显示的变量名称
        private static final String PORT_NAME = "PORT";//设置GUI页面显示的变量名称
        private static final String FILEPATH_NAME = "FILEPATH";//设置GUI页面显示的变量名称
        String host;
        int port;
        String filePath;
    
        @Override
        public SampleResult runTest(JavaSamplerContext sc) {
    
            SampleResult sr = new SampleResult();
            sr.setSampleLabel("Socket Test");
            try {
                //压测业务逻辑代码
                System.out.println("test")
                //模拟异常
                //System.out.println(1/0);
                sr.setSuccessful(true);
                sr.setResponseData("上传成功!", null);//将数据打印到查看结果树当中
            } catch (Exception e) {
                e.printStackTrace();
                sr.setSuccessful(false);
                sr.setResponseData("上传失败!" + e.getMessage(), null);//将数据打印到查看结果树当中
            } finally {
                sr.sampleEnd();
            }
            sr.setDataType(SampleResult.TEXT);
            return sr;
        }
    
    
        @Override
        public Arguments getDefaultParameters() {
            Arguments params = new Arguments();
            params.addArgument(HOST_NAME, "127.0.0.1");
            params.addArgument(PORT_NAME, "15997");
            params.addArgument(FILEPATH_NAME, "D:\\test.mp4");
            return params;
        }
    
        @Override
        public void setupTest(JavaSamplerContext context) {
            host = context.getParameter(HOST_NAME);
            port = Integer.parseInt(context.getParameter(PORT_NAME));
            filePath = context.getParameter(FILEPATH_NAME);
            super.setupTest(context);
        }
    
    }

1.3 把应用打包成jar包,并放到apache-jmeter\\lib\\ext下面

**二 使用工具执行自定义任务测试**

2.1 添加一个java任务

**三 查看请求结果**

socket上传都成功了
