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
