Jmeter 与 MongoDB 发生连接错误

Question

我想在我的mongodb数据库上执行负载测试。所以我将mongodb驱动程序添加到bin/ext文件夹并重新启动jmeter。我选择了JSR223采样器并选择groovy作为我的语言，并添加了连接代码，如下所示

import com.mongodb.*
import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoClient;
import com.mongodb.MongoClientSettings;
import com.mongodb.ServerAddress;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import org.bson.Document;
import java.util.Arrays;
try {
MongoClientSettings settings = MongoClientSettings.builder()
.applyToClusterSettings {builder -> 
builder.hosts(Arrays.asList(new ServerAddress(vars.get("mongoHost"),vars.get("mongoPort").toInteger())))}
.build();
MongoClient mongoClient = MongoClients.create(settings);
MongoDatabase database = mongoClient.getDatabase(vars.get("databaseName"));
MongoCollection<Document> collection = database.getCollection(vars.get("collectionName"));
vars.putObject("collection", collection);
return "Connected to " + vars.get("collectionName");
}
catch (Exception e) {
SampleResult.setSuccessful(false);
SampleResult.setResponseCode("500");
SampleResult.setResponseMessage("Exception: " + e);
}

mongoHost，mongoPort，databaseName，collectionName在用户定义的变量(测试计划(中配置。 当我运行采样器时出现错误

您需要将以下库添加到 JMeter 类路径中：

1. mongo-java-driver
2. 博森

库版本必须与您的MongoDB版本匹配(或至少兼容(，可以通过在MongoDB shell中运行db.version()查询来获取

需要重新启动JMeter才能获取库
