## 一、本次实验目的 ##

IDEA新建maven项目，使用java开发自定义jmeter的请求。

本次开发使用的代码，会百度云分享给大家。

## 二、本次实验环境 ##

<table>     
 <tbody> 
  <tr> 
   <td> <p>Idea</p> </td> 
   <td> <p>2017.02</p> </td> 
  </tr> 
  <tr> 
   <td> <p>Jmeter</p> </td> 
   <td> <p>5.1.1</p> </td> 
  </tr> 
 </tbody> 
</table>

## 三、新建maven项目 ##

pom.xml文件中导入依赖。

<dependencies>  <dependency> <groupId>org.apache.jmeter</groupId> <artifactId>ApacheJMeter_functions</artifactId> <version>5.1.1</version> </dependency>  <dependency> <groupId>org.apache.jmeter</groupId> <artifactId>ApacheJMeter_core</artifactId> <version>5.1.1</version> </dependency>  <dependency> <groupId>org.apache.jmeter</groupId> <artifactId>ApacheJMeter_java</artifactId> <version>5.1.1</version> </dependency>  <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.5</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.47</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> </dependencies>

## 四、代码编写 ##

### 4.1、以上一节监控的demo实现的两个接口为例，来编写实现请求的自定义请求 ###

打开jmeter，添加javarequest如下图所示：

![image.png][]默认只有两个class。

### 4.2、新建class实现JavaSamplerClient接口 ###

package com.jmeter.functions; import org.apache.jmeter.config.Arguments; import org.apache.jmeter.protocol.java.sampler.JavaSamplerClient; import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext; import org.apache.jmeter.samplers.SampleResult; public class CustemRequest implements JavaSamplerClient { @Override public void setupTest(JavaSamplerContext javaSamplerContext) { } @Override public SampleResult runTest(JavaSamplerContext javaSamplerContext) { return null; } @Override public void teardownTest(JavaSamplerContext javaSamplerContext) { } @Override public Arguments getDefaultParameters() { return null; } }

我们可以看到，具体会实现4个方法。

### 4.3、实现具体方法 ###

启动上一节实现的应用。localhost:8086

![image.png][image.png 1]

具体实现代码如下：

package com.jmeter.functions; import com.alibaba.fastjson.JSONObject; import org.apache.http.HttpEntity; import org.apache.http.NameValuePair; import org.apache.http.client.methods.CloseableHttpResponse; import org.apache.http.client.methods.HttpGet; import org.apache.http.client.utils.URIBuilder; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.message.BasicHeader; import org.apache.http.message.BasicNameValuePair; import org.apache.http.util.EntityUtils; import org.apache.jmeter.config.Arguments; import org.apache.jmeter.protocol.java.sampler.JavaSamplerClient; import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext; import org.apache.jmeter.samplers.SampleResult; import java.net.URISyntaxException; import java.util.LinkedList; import java.util.List; import java.util.Random; public class CustemRequest implements JavaSamplerClient { //定义显示请求地址的变量名 private static final String REQUEST_RUL = "URL"; //定义默认请求的URL地址 private static final String DEFAULT_URL = "http://localhost:8086/user/get"; //用户输入的URL private String inputUrl; //用来保存http请求的响应结果，并把结果放到jmeter的查看结果树里面 private String ResponseResult; //返回成功的状态码 private static final int SUCCESS_CODE = 200; //以下方法，打印输出的目的就是检验此4个方法的执行顺序，大家执行的时候可以后台结果详细查看 @Override public void setupTest(JavaSamplerContext javaSamplerContext) { System.out.println("******setupTest******"); inputUrl = javaSamplerContext.getParameter(REQUEST_RUL,DEFAULT_URL); System.out.println("用户默认输出的URL地址------>:" + inputUrl); } /** * 真正执行的方法 * @param javaSamplerContext * @return */ @Override public SampleResult runTest(JavaSamplerContext javaSamplerContext) { SampleResult sampleResult = new SampleResult(); Object[] param = new Object[]{ "id"}; Object[] value = new Object[]{ 26}; List<NameValuePair> nameValuePairs = getParam(param, value); /** * 标记一个事务的开始 */ sampleResult.sampleStart(); try { ResponseResult = (String) sentGetRequest(inputUrl, nameValuePairs); } catch (Exception e) { e.printStackTrace(); } sampleResult.setSampleLabel("自定义本地的请求访问"); sampleResult.setSuccessful(true); //告诉查看结果树是否成功 sampleResult.setResponseData(ResponseResult,"utf-8"); sampleResult.
