JMeter 测试 JAVA 接口

使用JMeter测试JAVA接口，需要编写一个java类，继承AbstractJavaSampleClient，实现具体接口的调用，然后将此工程打包为一个jar包，放置在JMETER_HOME\lib\ext目录下，然后在JMeter里配置调用。

编写Java类，继承AbstractJavaSampleClient
打包 jar
将jar包放置至 JMETER_HOME\lib\ext 目录
JMeter里配置调用

1. 添加依赖

<dependency>
    <groupId>org.apache.jmeter</groupId>
    <artifactId>ApacheJMeter_java</artifactId>
    <version>2.7</version>
</dependency>

2. 编写Java类

public class AdSearchServiceTest extends AbstractJavaSamplerClient {

    private static AdSearchService adSearchService;

    static {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        adSearchService = applicationContext.getBean("adSearchService", AdSearchService.class);
    }

    //
    @Override
    public SampleResult runTest(JavaSamplerContext javaSamplerContext) {
        SampleResult sampleResult = new SampleResult();
        String keyword = javaSamplerContext.getParameter("keyword");
        AdSearchService.Param param = new AdSearchService.Param();
        param.setKeyword(keyword);
        param.setStart(1);
        param.setLimit(10);
        long start = System.currentTimeMillis();
        sampleResult.sampleStart();
        try {
            SearchApiResult kievResult = adSearchService.search(param);
            sampleResult.setResponseData(kievResult.getJson(), "utf-8");
            sampleResult.setLatency(System.currentTimeMillis() - start);
            sampleResult.setDataType(SampleResult.TEXT);
            sampleResult.setSuccessful(true);
        } catch (Exception e) {
            sampleResult.setSuccessful(false);
        }
        sampleResult.sampleEnd();
        return sampleResult;
    }


    public static void main(String[] args) {
        AdSearchServiceTest kiev = new AdSearchServiceTest();
        Arguments arguments = new Arguments();
        arguments.addArgument("keyword", "微信");
        JavaSamplerContext context = new JavaSamplerContext(arguments);
        SampleResult result = kiev.runTest(context);
        System.out.println(new String(result.getResponseData()));
    }
}

注意以下参数：

sampleResult.sampleStart();
sampleResult.setSuccessful(true/false);
sampleResult.sampleEnd();

由于需要统计耗时以及请求成功与否的判断，需要设置以上参数，方便监听器统计测试信息

3. 打包

打包时需将相关依赖的包一同打包，否则会出现类找不到错误。(没试成功)
分开打包。打包时，将依赖 copy 至指定目录，然后将 jar 添加至 JMeter 的 ex t目录，最后在 JMeter 界面上指定依赖的 jar 包的目录。
