How Microservices communicate? API BEST practices | Java | Spring Boot | REST API #3

[@manamohansamal1040]

Webclient is non blocking in nature but as of my knowledge if we use .block() it blocks the current thread and becomes blocking in nature . If we have to use non blocking feature we should return a Mono or Flux.

[@SeleniumExpress]

Hi Manamohan ! Thanks for the correction. I went with the flow and used block () to remove the error as I already had the AddressResponse written in return and forget to explain it further. I noticed the same thing during editing but forgot to add a text annotation as well. Pinning this comment. Thank you.

[@manamohansamal1040]

Hello Abhilash, thank you for making this types of videos with such deep explanation ❤️ and replying to my comment it means a lot . I do understand it not just a one line code change to magically move the synchronisation process to asynchronous, there are a lot of changes required and your explanation you just showed how to use webclient in place of rest template. Once again big fan of your the level of knowledge you have and type of explanation you gave ❤️❤️

@@manamohansamal1040 Thank you Manamohan. Means a lot ❤️❤️

For above case address response isn't mono or flux type it's an entity class, if you return mono or flux it won't accept right, how can we resolve this

[@dbarasuk1600]

I'm telling you, it's sweet. To find this tuto free is a miracle. Well explained with great examples. You hide nothing or neglect any aspect people need to know. Sir, keeping going in this way, i appreciate.

Super teaching sir,I understand all the things, It's very interesting try to complete all the concepts in microservices

[@mberrachdi]

Thank you for this deep explanation about Sync and Async communication between microservices and how can the choice of each approach can increases or decreases the performance of our web application.

If there is a multiple address like Present address and permanent address so we need lists then how to return it?

[@srikanthakurathi5544]

Please reply as soon as possible

[@SeleniumExpress]

Inside your AddressResponse dto keep some more dto instance like PresentAddressDTO PermanentAddressDTO AddressResponseDTO will be a wrapper for all

[@alessandrobruni568]

Thank you. These lessons are really great. I have searched of you also teach aboute Spring Boot test ( Mokito, Junit) but i have found nothing. Is that correct?

[@dineshdevagalla2918]

Can someone please let me know Selenium Express created such animations while explaining. Can you please let me know tools required for doing such animations.

[@marcoghisellini4688]

I'm sorry Sir, this is not the right way to make communications between services. Synchronous communications with HTTP protocol is not a good practice, in this example services are not loose coupling and webClient used in blocking way. All this things could brings a lot of confusion to who is not familiar to microservices environment. I appreciated the effort for this video but I'd recommend you to review your architectural choices.

[@shriniwasbharadwaz1183]

@Everyone when i trying to put address-service base url in applicaiton.yaml file it is not working as expected.Can someone tell me how to handle this

[@k.ppandit5516]

Hi I have a question regarding webClient the question is when thread serves another request then how dies it know that its 1st response is ready to serve cleint side . is there any internal process by which it know this response belong to which request

[@mars3142]

Are you sure, that your webclient example is non-blocking? I believe it's still blocking, because you use ".blocking()". In my understanding, the return type of the function needs to be "Mono" and you should map/flatmap the results within the service.

[@springboot-m7f]

hii sir i want springboot-microservices full course as u teached .how can i get u r full course

[@d3nnyyy]

For those who have a problem with running some certain service on different ports: 1) Go to "Edit Configurations" near the Run button at the top 2) Click "Modify options" 3) And there in the "Operating System" section, click on the "Allow multiple instances"

[@jayjoshi1366]

My 1st-half is done Abhilash, and it was really amazing. I won't have ever received such level of knowledge from anywhere and anyone in the world around. I am watching from Canada and shortly will be ready to get in market for job applications and then interviews. I find each and every material very helpful, and even if you take a bit more time to explain and the sessions are longer, I feel confident after each session and get encouraged for the next one. Not even in my bachelors or PG course, I was so excited to learn new, but "YOU ARE A GEM OF A PERSON" which makes me attracted to your next material and I wait for new recorded sessions everytime I am going through your series. A BIG BIG THANK YOU TO YOU - ABHILASH TILL NOW AND GOD BLESS FOREVER!! Please also share some links with me regarding interview prep from top to bottom in Java backend (Core to Advanced Java).

If it's a maven project, we have a maven button towards right pane of the Intellij, click on that and click on '+' button to import maven project(s) and select this. it will be imported. Hope it helps!

[@nstha8848]

Hello Abhilash, I saw 41:00 where you injected the baseurl and rest template through construtor it looks fine only when you current service is pointing to only one other service thtough rest call (in your case address service)... but there might be a chance where your employee service might need to hit other service rest template from the same service, at that time there might be a problem. I am just saying hard coding them in the constructor might be risky in future
