1疟暖、驅(qū)動(dòng)包選擇

如果MongoDB版本是3.x以下卡儒，那么用jmeter自帶的mongo-java-driver-2.11.3.jar即可；
如果MongoDB版本是3.x以上俐巴，則需要mongo-java-driver-2.13.2.jar骨望，或者更高版本。
將驅(qū)動(dòng)包放在 apache-jmeter-x.x\lib目錄下或者apache-jmeter-x.x\lib\ext目錄下即可

2欣舵、添加Sampler擎鸠，編寫java代碼訪問mongo

可選擇添加JSR223 Sampler（groovy）或者BeanShell Sampler，這2種采樣器均支持java缘圈，但略有不同劣光，語法有些許差異。此處以JSR223 Sampler（groovy）為例准验。

代碼如下：

import com.mongodb.*;
import java.util.Set;

MongoClient mongoClient = new MongoClient("127.0.0.1",27017);  //根據(jù)IP赎线、端口連mongo
DB db = mongoClient.getDB("test");   //選擇數(shù)據(jù)庫
Set<String> collectionNames = db.getCollectionNames();
log.info(db.getName() + "包含如下集合：" + collectionNames.size());
for (String collectionName : collectionNames) {
 log.info(collectionName);
}
log.info("數(shù)據(jù)庫連接成功");
DBCollection dbCollection = db.getCollection("col_1");  //選擇集合
log.info("集合連接成功");
BasicDBObject searchObj = new BasicDBObject();
searchObj.put("name", "zhf");
DBObject result = dbCollection.findOne(searchObj);
log.info("==============================>>>");
log.info(result.toString());
vars.put("email",result.get("email"));
log.info(vars.get("email"));

運(yùn)行jmeter廷没，查看效果：

3糊饱、由于直接在jmeter上寫代碼不是太方便，建議在IDEA上調(diào)試java代碼

建maven項(xiàng)目颠黎，添加依賴另锋，pom.xml文件參考如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>zhf</groupId>
    <artifactId>zhf</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongo-java-driver</artifactId>
            <version>2.13.2</version>
        </dependency>
    </dependencies>
</project>

測試代碼如下：

import com.mongodb.*;
import java.util.Set;

public class Test {
    public static void  main(String[] args){
        try {
            MongoClient mongoClient = new MongoClient("127.0.0.1",27017);
            DB db = mongoClient.getDB("test");
            Set<String> collectionNames = db.getCollectionNames();
            System.out.println(db.getName() + "包含如下集合：");
            for (String collectionName : collectionNames) {
                System.out.println(collectionName);
            }
            System.out.println("數(shù)據(jù)庫連接成功");
            DBCollection dbCollection = db.getCollection("col_1");
            System.out.println("集合連接成功");
            BasicDBObject searchObj = new BasicDBObject();
            searchObj.put("name", "zhf");
            DBObject result = dbCollection.findOne(searchObj);
            System.out.println(result);
            System.out.println(result.get("sex"));
        } catch (Exception e) {
            System.err.println(e.getClass().getName() + ": " + e.getMessage());
        }
    }
}
