jmeter 实现java请求1方法有两种:
第一种: 继承抽象类 MyJavaClass extends AbstractJavaSamplerClient{ }
第二种:实现 JavaSamplerClient 接口 SecretClass implements JavaSamplerClient{ }
这里我用第二种：
JavaSamplerClient主要有4个方法：
public void setupTest(JavaSamplerContext ctx) {} //可以为空
public SampleResult runTest(JavaSamplerContext ctx) {} //这个是编写自定义java请求的核心代码区
public void teardownTest(JavaSamplerContext ctx) { } // 可为空
public Arguments getDefaultParameters() {} // 参数入口区
代码实现：
package com.javareq;
import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
import org.apache.jmeter.samplers.SampleResult;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class SecretClass implements JavaSamplerClient {
private static final Logger logger = LoggerFactory.getLogger(SecretClass.class);
@Override
public void setupTest(JavaSamplerContext ctx) {
}
@Override
public SampleResult runTest(JavaSamplerContext ctx) {
SampleResult result= new SampleResult();
String secret=ctx.getParameter("secret");
String message=ctx.getParameter("message");
String algorithm=ctx.getParameter("algorithm");
result.sampleStart();
String response=javaSecretUtil.EncryptHmacSha1(secret,message,algorithm);
result.setResponseData(response,"utf-8");
result.setDataType(SampleResult.TEXT);
result.setSuccessful(true);
result.setResponseMessage("方法执行成功！");
result.setResponseCode("0");
result.sampleEnd();
logger.info("result finally get as String is : "+ result.getResponseDataAsString());
return result;
}
@Override
public void teardownTest(JavaSamplerContext ctx) {
}
@Override
public Arguments getDefaultParameters() {
Arguments arguments =new Arguments();
arguments.addArgument("secret","");
arguments.addArgument("message","");
arguments.addArgument("algorithm","");
return arguments;
}
// public static void main(String[] args) {
// SecretClass demo = new SecretClass();
// Arguments arguments = new Arguments();
// arguments.addArgument("secret","hello");
// arguments.addArgument("message","key");
// arguments.addArgument("algorithm","HmacSHA1");
//
// String response=codecHmacSha1.hmacSha1("hello","key","HmacSHA1");
//
// JavaSamplerContext ctx=new JavaSamplerContext(arguments);
// demo.setupTest(ctx);
// demo.runTest(ctx);
// demo.teardownTest(ctx);
//
//
// }
}
main方法为测试使用，使用完打包前注释掉

打包完成放入lib/ext测试请求：
监听结果树：
当然也可以本地先调试好再打包：
使用打包前要注释的main方法调试，用完记得注释掉在打包前：
