我在Jmeter中的常规脚本执行没有错误，但是无法在Mongo DB中插入文档，这可能是什么问题？

Question

我在Jmeter中编写了以下脚本，用于在MongoDB中插入文档。我的脚本执行成功，但是没有执行所需的任务，即未在数据库中插入记录。我想念什么？谁能帮忙

import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoClient;
import com.mongodb.MongoClientSettings;
import com.mongodb.client.MongoCollection;
import com.mongodb.ServerAddress;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import com.mongodb.BasicDBObject;
import com.mongodb.DBObject;
import com.mongodb.DBCursor;
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");




//String json = ('{"EmployeeOID":12345,"EmployeeName":"Test Automation through Jmeter","Employee_Type_OID":4,"Rank":0,"Rating":0,"Score":0,"Supervisor_OID":56789,"TRGEmpID":"012345T"}');
//DBObject insertEmployee = (DBObject)JSON.parse(json);


BasicDBObject insertEmployee = new BasicDBObject();
    insertEmployee.put("EmployeeOID",12345);
    insertEmployee.put("EmployeeName", "Test Automation through Jmeter");
    insertEmployee.put("Employee_Type_OID",4);
        insertEmployee.put("Rank",0);
            insertEmployee.put("Rating",0);
                insertEmployee.put("Score",0);
                    insertEmployee.put("Supervisor_OID",56789);
                        insertEmployee.put("CompanyID","012345T");


    collection.insert(insertEmployee);

    DBCursor cursorDoc = collection.find();
    while (cursorDoc.hasNext()) {
        System.out.println(cursorDoc.next());

    }


    }
    catch (Exception e) {
    SampleResult.setSuccessful(false);
    SampleResult.setResponseCode("500");
    SampleResult.setResponseMessage("Exception: " + e);
    }

您的脚本中包含return keyword，在此阶段执行结束。关键字return下的行将永远不会执行，因此您将无法看到插入的对象，因为代码无法运行。

删除此行：

return "Connected to " + vars.get("collectionName");

并且您的脚本应按预期开始工作（或至少开始失败）
