本篇文章主要講解jmeter如何測試java請求，以項目中某個接口為例，請求數據為post，返回也為post

1：新建maven工程，pom文件為

1

2 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

2：新建JmeHttpRequestPost.java類

1 packagecom.ustcinfo.jmeter;2

3 importjava.io.DataOutputStream;4 importjava.io.InputStream;5 importjava.net.URL;6 importjava.net.URLConnection;7

8 importorg.apache.commons.io.IOUtils;9 importorg.apache.jmeter.config.Arguments;10 importorg.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;11 importorg.apache.jmeter.protocol.java.sampler.JavaSamplerContext;12 importorg.apache.jmeter.samplers.SampleResult;13

14 public class JmeHttpRequestPost extendsAbstractJavaSamplerClient {15

16 private String number = "number";17 private String number_value = "18134536460";18

19

20 /*

21 * 參數化，number22 */

23 @Override24 publicArguments getDefaultParameters() {25 Arguments params = newArguments();26 params.addArgument(number, number_value);27 returnparams;28 }29

30 /*

31 * 運行方法32 */

33 publicSampleResult runTest(JavaSamplerContext arg0) {34 SampleResult sr = newSampleResult();35 try{36 /*參數獲取*/

37 String number = arg0.getParameter("number");38 sr.sampleStart();39 /*請求地址*/

40 String URL = "http://ip:port/WSSPort/";41 /*請求報文*/

42 String Json = "";43 Json="{"

94 +"]"

95 +"}"

96 +"}";97 /*調用post請求方法*/

98 String postResult =doHttpPost(Json, URL);99 /*設置響應報文內容*/

100 sr.setResponseData(postResult, null);101 sr.setDataType(SampleResult.TEXT);102 sr.setSuccessful(true);103 sr.sampleEnd();104 } catch(Exception e) {105 e.printStackTrace();106 }107

108 returnsr;109 }110

111 /**

117 */

118 public staticString doHttpPost(String xmlInfo, String URL) {119 byte[] xmlData =xmlInfo.getBytes();120 InputStream instr = null;121 try{122 URL url = newURL(URL);123 URLConnection urlCon =url.openConnection();124 urlCon.setDoOutput(true);125 urlCon.setDoInput(true);126 urlCon.setUseCaches(false);127 urlCon.setRequestProperty("Content-Type", "text/xml");128 urlCon.setRequestProperty("Content-length", String.valueOf(xmlData.length));129 DataOutputStream printout = newDataOutputStream(urlCon.getOutputStream());130 printout.write(xmlData);131 printout.flush();132 printout.close();133 instr =urlCon.getInputStream();134 byte[] bis =IOUtils.toByteArray(instr);135 String ResponseString = new String(bis, "UTF-8");136 if ((ResponseString == null) || ("".equals(ResponseString.trim()))) {137 System.out.println("返回空");138 }139 returnResponseString;140

141 } catch(Exception e) {142 e.printStackTrace();143 return "0";144 } finally{145 try{146 instr.close();147 } catch(Exception ex) {148 return "0";149 }150 }151 }152 }153

3：在maven工程src/main下面新建assembly.xml文件，用作maven打包

1

2 assembly

3

4 tar.gz

5

6 true

7

8

9 ${project.build.directory}/dubbo/META-INF/assembly/bin

10 bin

11 0755

12

13

14 src/main/assembly/conf

15 conf

16 0644

17

18

19

20

21 lib

22

23

24

4：打包該工程，maven install，打包完成后可以看到target下生成了兩個文件一個java-post-0.0.1-SNAPSHOT-assembly.tar還有一個java-post-0.0.1-SNAPSHOT.jar

將java-post-0.0.1-SNAPSHOT-assembly.tar中的lib文件夾下所有的jar包拷貝到jmeter的lib目錄下，如果有重復的，則不替換用jmeter原生的jar包

將java-post-0.0.1-SNAPSHOT.jar拷貝到jmeter的lib/ext目錄下

5：啟動jmeter，驗證該jar功能是否正常，新建一個java請求，如果有參數化可設置參數化文件

上圖為兩個線程測試了一下，發現調用通過成功，響應數據正常返回，故該腳本可以正常使用

至于如何用這個jmx腳本做性能測試，我就不在重復了，參考我的博文-jmeter命令行運行-單節點測試或者分布式測試
