1.mongo-java-driver-*.jar包选用

下载MongoDB驱动mongo-java-driver-2.13.2.jar，放置D:\Program Files\apache-jmeter-3.1\lib，删除原来的mongo-java-driver-2.11.3.jar；
注意：由于MongoDB3.x使用的是SHA1加密方式，jmeter自带的2.11.3版本只支持CR;

2.Jmeter新建JSR223 Sample

线程组新建JSR223 Sample，Language选择groovy，删除MongoDB数据脚本如下

import com.mongodb.*;
import java.util.List;
import java.util.ArrayList;

            ServerAddress serverAddress = new ServerAddress("${IP}",port);
            List<ServerAddress> addrs = new ArrayList<ServerAddress>();
            addrs.add(serverAddress);

            MongoCredential credential = MongoCredential.createScramSha1Credential("${username}", "${db_name}", "${passwd}".toCharArray());
            List<MongoCredential> credentials = new ArrayList<MongoCredential>();
            credentials.add(credential);

            MongoClient mongoClient = new MongoClient(addrs,credentials);

            DB db = mongoClient.getDB("${db_name}");
            DBCollection dbCollection = db.getCollection("${Collection}");

            BasicDBObject delete = new BasicDBObject("userId",'${userId}');
            dbCollection.remove(delete);

1.调试脚本

若直接在Jmeter操作不便，可以先在idea先调试脚本，配置pom.xml如下

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

2.脚本内容

import com.mongodb.*;
import java.util.List;
import java.util.ArrayList;
public class mongo {
    public static void main(String[] args){
        try {
            ServerAddress serverAddress = new ServerAddress("IP",3717);
            List<ServerAddress> addrs = new ArrayList<ServerAddress>();
            addrs.add(serverAddress);
            MongoCredential credential = MongoCredential.createScramSha1Credential("username", "db_name", "passwd".toCharArray());
            List<MongoCredential> credentials = new ArrayList<MongoCredential>();
            credentials.add(credential);
            MongoClient mongoClient = new MongoClient(addrs,credentials);
            DB db = mongoClient.getDB("db_name");
            System.out.println("数据库连接成功");
            DBCollection dbCollection = db.getCollection("Collection_name");
            System.out.println("集合连接成功");
            BasicDBObject delete = new BasicDBObject("userId","${userId}");
            WriteResult result = dbCollection.remove(delete);
            System.out.println(result.toString());
        } catch (Exception e) {
            System.err.println(e.getClass().getName() + ": " + e.getMessage());
        }
    }
}
