jmeter java性能测试

本篇文章主要讲解jmeter如何测试java请求，以项目中某个接口为例，请求数据为post，返回也为post

1：新建maven工程，pom文件为

 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
     <modelVersion>4.0.0</modelVersion>
     <groupId>com.ustcinfo.jmeter</groupId>
     <artifactId>java-post</artifactId>
     <version>0.0.1-SNAPSHOT</version>
     <name>HttpRequestPost</name>
     <dependencies>
        <!-- httppost请求依赖jar包 -->
         <dependency>
             <groupId>commons-io</groupId>
             <artifactId>commons-io</artifactId>
             <version>2.5</version>
         </dependency>
         <!-- java jmeter依赖jar包 -->
          <dependency>
             <groupId>org.apache.jmeter</groupId>
             <artifactId>ApacheJMeter_core</artifactId>
             <version>3.0</version>
         </dependency>
         <dependency>
             <groupId>org.apache.jmeter</groupId>
             <artifactId>ApacheJMeter_java</artifactId>
             <version>3.0</version>
         </dependency>
     </dependencies>

     <build>
         <plugins>
             <plugin>
                 <artifactId>maven-assembly-plugin</artifactId>
                 <configuration>
                     <descriptor>src/main/assembly/assembly.xml</descriptor>
                 </configuration>
                 <executions>
                     <execution>
                         <id>make-assembly</id>
                         <phase>package</phase>
                         <goals>
                             <goal>single</goal>
                         </goals>
                     </execution>
                 </executions>
             </plugin>
         </plugins>
     </build>
 </project>

2：新建JmeHttpRequestPost.java类

 package com.ustcinfo.jmeter;

 import java.io.DataOutputStream;
 import java.io.InputStream;
 import java.net.URL;
 import java.net.URLConnection;

 import org.apache.commons.io.IOUtils;
 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 JmeHttpRequestPost extends AbstractJavaSamplerClient {

     private String number = "number";
     private String number_value = "18134536460";

     /*
      * 参数化，number
      */
     @Override
     public Arguments getDefaultParameters() {
         Arguments params = new Arguments();
         params.addArgument(number, number_value);
         return params;
     }

     /*
      * 运行方法
      */
     public SampleResult runTest(JavaSamplerContext arg0) {
         SampleResult sr = new SampleResult();
         try {
             /*参数获取*/
             String number = arg0.getParameter("number");
             sr.sampleStart();
             /*请求地址*/
             String URL = "http://ip:port/WSSPort/";
             /*请求报文*/
             String Json = "";
             Json="{"

                     +"}"
                     +"}";
             /*调用post请求方法*/
             String postResult = doHttpPost(Json, URL);
             /*设置响应报文内容*/
             sr.setResponseData(postResult, null);
             sr.setDataType(SampleResult.TEXT);
             sr.setSuccessful(true);
             sr.sampleEnd();
         } catch (Exception e) {
             e.printStackTrace();
         }

         return sr;
     }

     /**
      * doHttpPost：http发送json报文形式的post请求
      * @param xmlInfo 请求报文
      * @param URL  请求地址
      * @return String  响应内容
      * @exception
      */
     public static String doHttpPost(String xmlInfo, String URL) {
         byte[] xmlData = xmlInfo.getBytes();
         InputStream instr = null;
         try {
             URL url = new URL(URL);
             URLConnection urlCon = url.openConnection();
             urlCon.setDoOutput(true);
             urlCon.setDoInput(true);
             urlCon.setUseCaches(false);
             urlCon.setRequestProperty("Content-Type", "text/xml");
             urlCon.setRequestProperty("Content-length", String.valueOf(xmlData.length));
             DataOutputStream printout = new DataOutputStream(urlCon.getOutputStream());
             printout.write(xmlData);
             printout.flush();
             printout.close();
             instr = urlCon.getInputStream();
             byte[] bis = IOUtils.toByteArray(instr);
             String ResponseString = new String(bis, "UTF-8");
             if ((ResponseString == null) || ("".equals(ResponseString.trim()))) {
                 System.out.println("返回空");
             }
             return ResponseString;

         } catch (Exception e) {
             e.printStackTrace();
             return "0";
         } finally {
             try {
                 instr.close();
             } catch (Exception ex) {
                 return "0";
             }
         }
     }
 }
   

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

 <assembly>
     <id>assembly</id>
     <formats>
         <format>tar.gz</format>
     </formats>
     <includeBaseDirectory>true</includeBaseDirectory>
     <fileSets>
         <fileSet>
             <directory>${project.build.directory}/dubbo/META-INF/assembly/bin</directory>
             <outputDirectory>bin</outputDirectory>
             <fileMode>0755</fileMode>
         </fileSet>
         <fileSet>
             <directory>src/main/assembly/conf</directory>
             <outputDirectory>conf</outputDirectory>
             <fileMode>0644</fileMode>
         </fileSet>
     </fileSets>
     <dependencySets>
         <dependencySet>
             <outputDirectory>lib</outputDirectory>
         </dependencySet>
     </dependencySets>
 </assembly>

4：打包该工程，maven install，打包完成后可以看到target下生成了两个文件一个java-post-0.0.1-SNAPSHOT-assembly.tar还有一个java-post-0.0.1-SNAPSHOT.jar

将java-post-0.0.1-SNAPSHOT-assembly.tar中的lib文件夹下所有的jar包拷贝到jmeter的lib目录下，如果有重复的，则不替换用jmeter原生的jar包

将java-post-0.0.1-SNAPSHOT.jar拷贝到jmeter的lib/ext目录下

5：启动jmeter，验证该jar功能是否正常，新建一个java请求，如果有参数化可设置参数化文件

上图为两个线程测试了一下，发现调用通过成功，响应数据正常返回，故该脚本可以正常使用

至于如何用这个jmx脚本做性能测试，我就不在重复了，参考我的博文-jmeter命令行运行-单节点测试或者分布式测试
