gRPC with Spring Boot Example | Protobuf Stub & Skeleton | Tech Primers

[@weitanglau]

You won't believe it, but your videos saved my life! Keep up the good work

[@TechPrimers]

Glad they are helpful Lau Wei.

[@balajimathu9558]

Thanks for a clear and short explanation. Very good video to start learning gRPC

[@dramaqueenpahelsrivastava631]

Simply the best way to understand and implement Grpc. Thanks Sir

[@pelox3000]

Very useful and pragmatic crash course on grpc, thanks!

[@azharmobeen]

I was about to start series on gRPC and micro services and I saw your video. Keep it up. 👍👍❤️

[@ambarishkapil8004]

Thanks for the video man, really appreciate it.

[@kritikasharma2702]

Hey! I'm getting this error in the greeting parent pom.xml - 'packaging' with value 'jar' is invalid. Aggregator projects require 'pom' as packaging.

[@Priyam_Gupta]

Great video, would be really helpful for learning grpc for Java guys.

[@Anand-fy8oo]

gRPC is faster by avoiding heavy serialisation mechanisms like json and xml parser uses.. there are other alternatives of proto3 which uses better memory allocation and compression… gRPC is fast, but it is really tough to replace rest bcz of its flexibility on schema modifications ..

[@suranjanabasu1762]

Thanks for this excellent video.

[@guifanweng410]

osx-x86_64 can be replaced with ${os.detected.classifier} for auto detection

[@terjemahanminda-ahmadfahmi6343]

good video. keep it on. some suggestion, maybe you can demonstrate a comparison of how grpc is faster than rest protocol.

[@iLegendaryStar]

nice spring initializer!!

[@56murali]

How to differentiate get and post methods in GRPC?

[@Golbyzshorts]

How can we handle timeouts in grp call? Can we use resilience4j?

[@siddharthRoy2720]

Great video. Any idea on the client side implementation? For java service to service communication?

[@tombrodyy]

Great job on this

[@thanhtc1988]

can you update your github file to match with the result of this video. So much things in pom files that are different.

[@swastikpanda3635]

Bi directional streaming is required for this particular video session.

[@kritikasharma2702]

I'm getting error after running the message curl command - Error invoking method "com.example.grpc.GreetingService/greeting": error getting request data: invalid character 'm' looking for beginning of object key string

[@ravipanchal2259]

Sir, Thanks for the video. I have a question, how can we call one service from another as we do with RestTemplate

[@kirlampallimurty5115]

Great explanation, Thanks for this.

[@gangapurgrowthhub]

Could you please make a video using spring security in gRPC based microservices and also use spring data jpa for persistence

[@saratchandra4689]

It is almost like SOAP webservices. Instead of WSDL file, writing protobuf file & generating classes. As it has binary protocol, if spring has, spring native app with grpc support & reactive, that is crazy combination with respect to performance. Agree?

[@sachidanandhegde3777]

sir can you suggest website where i can springboot in deep

[@vijayank923]

Nice explanation, Could you please do for Gradle project .

[@Sumukh56]

Thanks🎉

[@saratchandra4689]

Nice explanation. So we can't test service in postman or browser? It is bit extra effort when compared with rest api's. In industry, people are using extensively?

[@adennis200]

Would, in a real world example, each service have another service as a dependency in their pom.xml?

[@TechPrimers]

Depends on the repo setup. Some companies use mono repo some don’t

[@laxmanmule9313]

please make video on Grpc test cases

[@exgenesysgis3459]

How do I change the port to listen to some other one since Prometheus is listening on 9090

[@TechPrimers]

There is a spring boot property called server.port. take a look at that

[@exgenesysgis3459]

@@TechPrimers sir it didn't work. Tried using yml file too. BTW I am using Mac M1

Hi ,could you please make a video with spring webflux with grpc...Thanks in advance

[@patrickmckenna4533]

Followed instructions and does not work, so I cloned the repo and still does not work..

[@alugbinabiodun]

...anyone tried this with spring-boot3? It's not starting my grpc server, but it's starting spring-boot on port 8080

[@johnchu4012]

Really good video that got me started on gRPC for Spring Boot. Curious, anyone knows the helpful terminal utility that shows the command parameters (see video time 25:32)?

[@TechPrimers]

Hi John. Here is the iterm setup steps which i have documented in my Github repo github.com/TechPrimers/iterm2-setup

[@pguti778]

Very good video!!!!

[@navedazhar4444]

What is difference between gRPC and REST?

[@bandapalliharish155]

Good video 👍. You mentioned that you are using M1 macbook. Can you please let me know if it is pro or air and also have you faced any issues related to programming I mean with any installations(java, maven, docker etc) on M1 laptops?

[@amabentil920]

Thank you so much

[@debkr]

Why not use use Vertx instead of Spring ?

[@mikedqin]

Great Intro to gRPC!!! Can you compare gRPC with RSocket? Which one is better? Thank you.

[@amitukai]

Good one...thanks !

[@naeembilal]

There have to be so many controller annotations required. Unless big players won't be interested in this, it will be another communication way like Corba and Rmi.

[@munawarabbas1636]

Thanks a lot man...Love From pakistan

[@TheGuroguro12]

Thank you, interesting.

[@gustawbobowski1333]

Hi, thanks for this video! I am super stumped on how exactly do I implement client stubs with this library in spring boot. I fail to inject them properly, would be super thankful for a demonstration.

[@sanjaykantheti4002]

Hi Ajay, Very informative video. We can also use bloom RPC ( like postman for rest) to test instead of grpcurl. Could you also explain unary, client streaming, server streaming, bidirectional calls as well

[@vietronaldo23w]

I think: - unary: client send one request and server will respond one response. - client streaming: client send a stream of messages and server will respond one response - server streaming: client send one request and server will respond a stream of message - bidirectional stream: client send a stream of messages and server will respond a stream of messages

[@TechPrimers]

In the plugin configuration, use the below xml. I hardcoded to osx since grpc doesnt have compiler for m1 chips yet. com.google.protobuf:protoc:3.4.0:exe:${os.detected.classifier}

[@abhijitprusty]

@@TechPrimers cool, it worked for me now.... just needed to change the hardcoded part - for windows its like - io.grpc:protoc-gen-grpc-java:${grpc.version}:exe:${os.detected.classifier}
