jmeter之自定义函数：随机生成手机号码

setup1：创建一个java项目、并生成一个包cn.com.functions 这个是固定写法

setup2：添加一个class，命名为RandomPhone 并继承AbstractFunction

setup3：导入依赖的库：

说明：最后一个文件到这里下载

所有代码如下

package cn.com.functions;

import java.security.SecureRandom;
import java.util.Collection;
import java.util.LinkedList;
import java.util.List;
import java.util.Random;
import org.apache.jmeter.engine.util.CompoundVariable;
import org.apache.jmeter.functions.AbstractFunction;
import org.apache.jmeter.functions.InvalidVariableException;
import org.apache.jmeter.samplers.SampleResult;
import org.apache.jmeter.samplers.Sampler;
import org.apache.jmeter.threads.JMeterVariables;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class RandomPhone extends AbstractFunction {
	private static final List<String> desc = new LinkedList();
	private static final String KEY = "__RandomPhoneNumber";
	private Object[] values;
	private static final Logger log = LoggerFactory.getLogger("testing");//这里是实例化log对象并调用debug方法进行调试
	static {
		desc.add("Name of variable in which to store the result (optional)");
	}

	private static final String[] telFirst = "134,135,136,137,138,139,150,151,152,157,158,159,130,131,132,155,156,133,153"
			.split(",");
	String phonenumberString = "";

	public String execute(SampleResult previousResult, Sampler currentSampler) throws InvalidVariableException {

		JMeterVariables vars = getVariables();

		try {

			Random random = new Random();
			String pheonindexString = telFirst[random.nextInt(telFirst.length)];

			String two = String.valueOf(random.nextInt(999) + 1000);
			String three = String.valueOf(random.nextInt(999) + 1000);
			phonenumberString = pheonindexString + two + three;

			if (vars != null && this.values.length > 0) {
				String varName = ((CompoundVariable) this.values[0]).execute().trim();

				vars.put(varName, this.phonenumberString);
			}
			if (log.isDebugEnabled()) {//如果开启debug模式，这会在jmeter控制台打印如下语句。用于调试使用
				log.debug(" 手机号段:{}  手机号是：{}", pheonindexString, phonenumberString);
			}
		} catch (Exception e) {

			e.printStackTrace();
		}

		return phonenumberString;
	}

	public void setParameters(Collection<CompoundVariable> parameters) throws InvalidVariableException {
		checkMinParameterCount(parameters, 0);
		this.values = parameters.toArray();
	}

	public String getReferenceKey() {
		return KEY;
	}

	public List<String> getArgumentDesc() {
		return desc;
	}
}

然后导入jmeter中查看导入结果：

可以看出函数运行正常。
