JMeter压测MongoDB

1、下载mongo-java-driver驱动

官方驱动：

https://mongodb.github.io/mongo-java-driver/

或者Maven：

https://mvnrepository.com/artifact/org.mongodb/mongo-java-driver

<!-- https://mvnrepository.com/artifact/org.mongodb/mongo-java-driver -->
<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongo-java-driver</artifactId>
    <version>3.8.2</version>
</dependency>

把mongo-java-driver-3.8.2.jar放到/usr/local/jmeter/apache-jmeter-5.1.1/lib/ext目录下

rm -rf mongo-java-driver-2.11.3.jar

# 删除/usr/local/jmeter/apache-jmeter-5.1.1/lib目录中旧版本的mongo-java-driver jar包

2、在MongoDB中创建jmeter_test库与blazemeter_tutorial集合

3、编写脚本，采用JSR223 Sampler

名称	值
mongoHost	192.168.1.111
mongoPort	27017
databaseName	jmeter_test
collectionName	blazemeter_tutorial

	return "Document inserted";

	SampleResult.setResponseCode("500");
	SampleResult.setResponseMessage("Exception: " + e);
