Jmeter使用MongoDb获取连接错误

Question

我想对我的 mongodb 数据库执行负载测试。所以我将 mongodb 驱动程序添加到 bin/ext 文件夹并重新启动了 jmeter。我选择了 JSR223 Sampler 并选择了 groovy 作为我的语言并添加了如下连接代码

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 Classpath：

1. mongo-java-driver
2. bson

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() query 来获得

需要重启 JMeter 才能获取库
