Question

我是新手，这可能是一个非常基本的问题，但我没有找到适合我的好样本。在JMeter 3.3中，我设置了JSR223 Sampler来查询mongo db中的几个参数。我成功连接到mongo并对集合进行了计数，现在我需要通过_id进行查询。我后来需要计算数组中的元素数量。到目前为止，甚至发现id没有用。工作部分：

import com.gmongo.*;
import com.mongodb.*;
import org.apache.jmeter.protocol.mongodb.config.MongoDBHolder;
import com.mongodb.DBCollection;                    // import DBCollection class

DB db = MongoDBHolder.getDBFromSource("mongo", "Users");
DBCollection collection = db.getCollection("DownloadTracking"); // get "zips" collection
long count = collection.getCount();
String result = String.valueOf(count);              // convert long to String
SampleResult.setResponseData(result.getBytes());

现在没有工作样本：

log.info db.collection.findOne()

2018-02-04 16:36:19,826 ERROR o.a.j.p.j.s.JSR223Sampler: Problem in JSR223 script JSR223 Sampler, message: javax.script.ScriptException: javax.script.ScriptException: groovy.lang.MissingPropertyException: No such property: collection for class: com.mongodb.DBApiLayer

实际上我需要得到这个对象的响应：

BasicDBObject query = new BasicDBObject("EntityOwner.UserId", ObjectId("544e0e6dcbda7101b0148739")); // create DBObject holding the query
DBObject result1 = collection.findOne(query);  // execute the query and store outcome into "result" DBObject
SampleResult.setResponseData(result1.toString().getBytes()); // set JSR223 sampler response to "result"

错误：

我尝试将对象放在JSON格式中，例如：.findOne({ "EntityOwner.UserId": ObjectId("544e0e6dcbda7101b0148739")})。它没用。

尝试修改您的查询，如下所示：

def query = new BasicDBObject()
query.put('EntityOwner.UserId', new org.bson.types.ObjectId('544e0e6dcbda7101b0148739'))
def result1 = collection.findOne(query)
