如何解决jmeter未捕获的异常java.lang.NoSuchMethodError：'java.lang.String org.bson.types.ObjectId.toHexString'

我正在使用jmeter测试mongodb。我按照https://dzone.com/articles/mongodb-performance-testing-with-jmeter

中的说明进行操作

在远程服务器上，我安装了mongodb，并将/etc/mongodb.conf更改为使用bindIP公共IP地址。在本地系统上，我调用了“ mongo”命令，并创建了一个名为jmeter_test的mongodb数据库和一个名为blazemeter_tutuorial的集合。

    > use jmeter_test
    switched to db jmeter_test
    > db.createCollection("blazemeter_tutorial")
    { "ok" : 1 }
    > show collections
    blazemeter_tutorial
    >

我安装了jmeter 5.3，还将其下载到lib / ext bson-4.1.0.jar groovy-3.0.5.jar和mongo-java-driver-3.12.7.jar中。我创建了一个新的测试计划，其中包含连接脚本所需的适当“用户定义的变量”。

mongoHost: 192.168.1.6
mongoPort: 27017
databaseName: jmeter_test
collectionName: blazemeter_tutorial

在该网页上找到的连接脚本如下：

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);
}

通过jmeter运行此脚本时，出现以下错误：

我不是Java方面的专家，但是对我来说，它看起来像是内部错误或某种与脚本无关的错误？有没有人见过这个？你能帮忙吗？

解决方法

有点远，但是mongo-java-driver-3.12.7.jar应该已经包含org.bson.types.ObjectId类，并且引入一个单独的版本可能会给您一个没有toHexString方法的类。我会尝试从方程式中删除bson-4.1.0.jar，看看会发生什么。

,

oops ..我发现lib /具有mongo-java-driver-2.11.3.jar和groovy-3.0.3.jar。

  1. 我从lib中删除了mongo-java-driver-2.11.3.jar
  2. 删除了我下载的ext / groovy-3.0.5.jar。

并重新运行jmeter connect脚本，它就起作用了！
