Jmeter test Dubbo interface

• dubbo
• Jmeter
• TestNG
• Spring

• Call through the way of jmeter secondary development (jar) (recommended, with requirements for coding ability)
• Call through JMeter plugins Dubbo

Call through jmeter secondary development (jar)

Resource allocation

//Introduce related resources under project lib file
 1. The dependent resources required by TestService: TestService.jar
 2.Jmeter dependent jars: jorphan.jar, ApacheJMeter_java.jar, ApacheJMeter_core.jar
 3.dubbo resource: dubbo.xsd

//Resource path
 //1.jorphan.jar (jmeter/lib for main debugging execution)
// 2.ApacheJMeter_java.jar,ApacheJMeter_core.jar (jmeter/lib/ext/)
//3.dubbo.xsd can download Dubbo resources directly through pom, and copy a dubbo.xsd from Dubbo corresponding to Maven warehouse 

• Create a new maven project and add the following dependencies in pom.xml configuration: Dubbo, Spring
• You also need to add the dependent test service corresponding to the test service

• spring configuration of Dubbo service consumers: create consumer.xml configuration under the resources directory (consumers)

For the configuration content of consumer.xml, please refer to the consumer configuration file of TestService
 (you can find the corresponding consumer profile from the deployment path of the corresponding service in the test environment, such as dubbo_client.xml)

• Local debugging results

• Package jar (after local debugging is ok, type jar and put it in jmeter/lib/ext /)

//Packing process
// The jar storage path is under the default current project out / artifact /
1.File -> Project Structure -> Artifats -> add Library file
2.Build -> Build Artifats -> Builds

• jmeter add the jar package you typed before and restart jmeter

• Call result

Called through JMeter plugins Dubbo

// Jmeter itself does not support Dubbo interface calls. You need to download a third-party plug-in to support 

// Download jmeter-plugins-dubbo-1.3.8-jar-with-dependencies.jar place jmeter/lib/ext / restart JMeter

// Additional dependent resources need to be added:

dubbo-2.5.3.jar
javassist-3.15.0-GA.jar
zookeeper-3.4.6.jar
zkclient-0.1.jar
jline-0.9.94.jar
netty-3.7.0-Final.jar
slf4j-api-1.7.5.jar
log4j-over-slf4j-1.7.5.jar


// Matters needing attention
1.When used zk，address Fill zk Address (used by cluster address","Separation),Use dubbo Direct connection, address Fill in direct connection address and service port
2.timeout: Service method call timeout(Millisecond)
3.version: Service version, consistent with the service provider's version
4.retries: Retry times of remote service call, excluding the first call, please set to0
5.cluster: Cluster mode, optional: failover/failfast/failsafe/failback/forking
6.group: Service grouping. When an interface has multiple implementations, it can be distinguished by grouping. It must be consistent with the service provider
7.Interface needs to fill in full type name, including package name
8.Parameter supports any type. The wrapper class can directly use java.lang The following packaging classes are used for small types:int,float,shot,double,long,byte,boolean,char，The custom class uses the class full name.
9.Parameter value, basic packing class and basic subtype directly use value, for example:intby1，booleanbytrueClass and List perhaps Map Such use json Format data.
