Thanks for this video! the gateway applica.yaml part i modified, as of today (20th Jan 2024) when i built this project, instead of spring.cloud.gateway.routes i did spring.cloud.gateway.mvc.routes i dont the exact reason but i think the first one requires spring web flux (reactive) and later one is based on our synchronous spring web Feel free to correct me if im wrong.

[@alacherif7204]

Thank you Ali for this video. It is interesting. With this solution, every time we need to add a new microservice we need to change/deploy the gateway. How can we add a new microservice without changing/deploying the gateway?

[@BoualiAli]

You don't need to re-deploy the gateway every time. Externalise the config to config server and the gateay will reload the config from there. That's why I added the config server patter

[@sweets7092]

Thank you so much I have implemented it all slightly differently as to work for my use case but overall the same and these have been great tutorials and great explanations I do have a question though we do this to enable load balancing but how would that work for your applications as the server port is into the config server so if u opened up another application it would still redirect to the first one?

you can only add it to the gateway. But it is also recommended that each microservice needs to check and validate the token

Hey! Great Sage, please, I found out that on the video you did not show few things. Hence applications fail for some of us without extensive knowledge. 1. On the Entities in both School & Student Micro-services. Your video didn't show that you added "GeneratedValue" on the Id 2. On the school service when you injected the student client "private final StudentClient client;", your video didn't show when you added the "final keyword" in order to enforce the injection. Thank you so much for wonderful lectures. I will be signing up for your courses because you are quite skilled in impacting knowledge.

I need to recheck the video. But I supposed that the viewer is familiar with Spring boot. If it is not the case, please watch the Spring boot for beginners video in my channel and you will have a better and clear understanding how the framework works and then this video will be like a piece of cake for you.

Very interesting video. However, I wonder if I just missed some steps about postsgresql. my student and school application won't start until I installed it and created the students and schools database manually and also set a password for the postgres default account. After both were running and tried to use postman to post the school entry, I got the following error, "ids for this class must be manually assigned before calling save():". I'm thinking that maybe I have to manually create the table first?

What you did is what needs to be done as a first step. I assumed that everyone is capable of setting up his own working environment and have things up and running before starting.

Assalaamu alaikum bro Ali. Thank you for all your video series which are only beneficial for us. I, as a self-learner, find your channel to be one the most useful ones to learn programming. However, I noticed something unusual about this microservices lesson. You are accessing api/v1/student/** endpoint both through its own port which is at 8090 and through gateway which is at 8222. I think all microservices, including student microservice, must be accessible only through gateway, when requested to other ports, 8090 or 8070 for instance, "path not found" response must be returned. And also, on Eureka server at localhost:8761, gateway did not appear as a running server like STUDENTS or SCHOOLS. Can you, please, make any suggestion to configure my microservice architechture so that it is only accessible though gateway? Thank you again.
