jmeter Uncaught Exception java.lang.NoSuchMethodError: 'java.lang.String org.bson.types.ObjectId.toHexString()'

问题

以下是翻译的内容：

我正在使用 JMeter 测试 MongoDB。我按照 https://dzone.com/articles/mongodb-performance-testing-with-jmeter 中的指示进行操作。

在远程服务器上，我安装了 MongoDB，并将 /etc/mongodb.conf 更改为使用公共 IP 地址绑定 bindIP。从我的本地系统中，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_tutorial 的集合。

    > use jmeter_test
    切换到数据库 jmeter_test
    > db.createCollection("blazemeter_tutorial")
    { "ok" : 1 }
    > show collections
    blazemeter_tutorial
    >

我安装了 JMeter 5.3，还从 lib/ext 下载了 bson-4.1.0.jar、groovy-3.0.5.jar 和 mongo-java-driver-3.12.7.jar。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的 'User Defined Variables'。

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

在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);
}

当我通过 JMeter 运行此脚本时，我得到以下错误：

2020-08-27 12:58:35,230 INFO o.a.j.e.StandardJMeterEngine: Running the test!
...
java.lang.NoSuchMethodError: 'java.lang.String org.bson.types.ObjectId.toHexString()'
...

我不是 Java 专家，但在我看来，这似乎是内部错误或某种错误，与脚本无关？有人以前见过这种情况吗？可以请您帮忙吗？

英文:

I am using jmeter to test mongodb.I following the instructions in https://dzone.com/articles/mongodb-performance-testing-with-jmeter

On a remote server I installed mongodb, and changed the /etc/mongodb.conf to use bindIP public IP address. From my local system, I invoked 'mongo' command and I created a mongodb database called jmeter_test and a collection called blazemeter_tutuorial.

    &gt; use jmeter_test
    switched to db jmeter_test
    &gt; db.createCollection(&quot;blazemeter_tutorial&quot;)
    { &quot;ok&quot; : 1 }
    &gt; show collections
    blazemeter_tutorial
    &gt;

I installed jmeter 5.3 and also downloaded into lib/ext bson-4.1.0.jar groovy-3.0.5.jar and mongo-java-driver-3.12.7.jar. I created a new test plan with appropriate 'User Defined Variables' needed for the connection script.

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

The connection script found on that web page is as follows:

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 -&gt; 
builder.hosts(Arrays.asList(new ServerAddress(vars.get(&quot;mongoHost&quot;),vars.get(&quot;mongoPort&quot;).toInteger())))}
.build();
MongoClient mongoClient = MongoClients.create(settings);
MongoDatabase database = mongoClient.getDatabase(vars.get(&quot;databaseName&quot;));
MongoCollection&lt;Document&gt; collection = database.getCollection(vars.get(&quot;collectionName&quot;));
vars.putObject(&quot;collection&quot;, collection);
return &quot;Connected to &quot; + vars.get(&quot;collectionName&quot;);
}
catch (Exception e) {
SampleResult.setSuccessful(false);
SampleResult.setResponseCode(&quot;500&quot;);
SampleResult.setResponseMessage(&quot;Exception: &quot; + e);
}

When I run this script though jmeter I get the following error:

I am not an expert in Java, but to me it looks like an internal error or some sort and not related the script? Has anyone seen this before? could you please help?

抱歉.. 我发现 lib/ 目录下有 mongo-java-driver-2.11.3.jar 和 groovy-3.0.3.jar。

我从 lib 目录中移除了 mongo-java-driver-2.11.3.jar
移除了我下载的 ext/groovy-3.0.5.jar。

然后重新运行了 jmeter 连接脚本，它成功运行了！

I removed the mongo-java-driver-2.11.3.jar from lib
Removed the ext/groovy-3.0.5.jar that I had downloaded.

and re-ran the jmeter connect script and it worked!

一个有点冒险的尝试，但 mongo-java-driver-3.12.7.jar 应该已经包含了 org.bson.types.ObjectId 类，并且引入一个单独的版本可能会导致您得到一个没有 toHexString 方法的版本。我建议尝试将 bson-4.1.0.jar 从项目中移除，看看会发生什么。

英文:

A bit of a long shot, but the mongo-java-driver-3.12.7.jar should already contain the org.bson.types.ObjectId class and pulling in a separate version might have given you one without the toHexString method. I would try removing the bson-4.1.0.jar from the equation to see what happens.
