57:03, I understood and am Feeling great too 😊 However, I still have a question. You mentioned that the employee service is calling the address service using the URL address/{empId}. But I noticed that you haven’t defined any relationship between the two entities in the entity classes. While I see that the tables are linked in the database, why isn't there a relationship established at the entity level? Additionally, when these services are in separate databases, how do you handle the configuration for this setup?"
Thank you abilash, your videos are verry easy to understand, also this MS serious goint to be verry helpfull for me. I am waiting next videos as well. Keep it up. Your ammazing teacher.❤️❤️
Hi Abilash, Thank you for the clear explanation about the microservices. I had one doubt, when i changed the spring versions in pom.xml, i have some error in entity class, it is not adopted to that version, could you please provide suggestions to resolve it. Thanks in advance.
Hi Abhilash, a well explained video about load balancing.❤️❤️ I have one doubt so far , the feign client is great removing lots of boilerplate code but what about the exception handling or error handling in case of a 4xx or 5xx , do we need to handle all those in the service class from where we are calling the proxy or is there any way to define the exception handlings as well ??
Hi Manamohan ! Glad that it helped ! There are different ways to handle feign exception which will be covered in the follow up lessons. For now you can find an attribute called fallBackFactory inside @FeignClient. Do a little research about that, it help you to override your feign client abstract methods and you can give a default fallback response / handle exception as per your need. Alternatively you can use a global exception handler of spring and create an exception handler to handle feign client exceptions. @ExceptionHandler(FeignException.class) public String handleFeignException(FeignException e, HttpServletResponse response) { //grab needed stuffs from the response } You can also learn about ErrorDecoder from feign. It will help you to decode the error response and handle exception as per your need.It's something like RestTemplate's ResponseErrorHandler if you are aware about .
Yes it makes sense now I was looking for something to replace the ResponseErrorHandler of rest template or to add fall back strategy with circuit breaker is in place . Thank you for the explanation ❤️❤️
if we are using REST protocols to communicate with other services that means this is just a distributed monoliths isn't it? please do a video on messaging queue based service communication.
Hi Abhilash. can you help me. I have error. It says : Consider defining a bean of type 'com.employee.employeeservice.service.AddressClient' in your configuration. It means even I make AddressClient a bean, using by @FeignClient annotation, but Spring can't find bean in IoC container. What to do?
according to Browser security policy -> browser follows SOP(Same organ policy) if you want to access data from another ports/host browser doesn't allow us to do that, that's why we use crossOrigin but here in this video how it is happening. sir can you please explain this.
Thank you for this wonderful course. I wonder how you would justified your paid students(incase they have queried you) of this batch that within a month or two you have uploaded this course for FREE for all of us :D .
What is the benefit of using client side load balancing over server side load balancing ? (I know its too early to ask) and why we are calling it client side although everything is on server ?
Does entity framework return the same object reference if I query the "logically" (in database) same object from different places. For example, I queried customer with name Joe Black, (and assume for now I know that there's only one Joe Black in the database.) Customer c = select ... blabla where ... Name == Joe Black...; and in somewhere else in the code, I queried Customer c2 = select... where.. ID==5 where 5 is the ID of Joe Black. I know that in the database they map to the same object, but DO they also map to the same object in code level? So does c1 equal to c2? I have lists to merge and check for logical equality of the objects (I cannot access the database for now) and I was wondering whether Entity Framework objects will play nicely with it or should I write my custom comparer classes.
Abhilash, your effort in explaining this is unmatched. Engaging and easy to understand. The Best Spring Course out there!
Feeling great, outstanding explanation
The way you are teaching is fun , informative and a lot inspiring!

Enjoy learning, happy to wait for next week lesson.
Thank you! See you next week.
thank you so much! I learnt about Feign Client and Ribbon, (load balancing)
Feeling Great!!🙇♂
Thanks sir for the video. Will be waiting for the next video
You are welcome! Sure, see you next Saturday 😊

feeling great sir
Great video 👏🏽👏🏽
Thanks, Paridhi !
Feeling great
UNDERSTOOD
Thank you
One question that if Feign client also non blocking then why spring is just deprecating the rest template, it should also deprecate the feign client?
Understood ❤
Lots of love bro God bless you
❤️
Feeling Great
Great Man😍
Love you sir it is from my heart
Thank you Manis ! It means a lot ❤️
38:05 example
43:14 . Run Multiple instance in sts
The security part is missing with the series which is key thing for inter service communication.
Do we have any configuration for feign client in config class
can we get recording of this whole course ,SIR??
Hi Avilashi, where to take the paid course for microservices @selenium express ? please lemme know..
love you brother ❤️🙏🏻
❤️❤️😊
Thanks for the video
You are welcome, Santosh!
Hi sir, i want to buy the full course but i didn't receive the confirmation mail in my mail id.can you please help me in this login process.
Thanks abhi ❤️
most welcome !
feeling grate
feeling great
I too. Glad to know that you have reached halfway
I will definitely buy this course if available on udemy because i cant wait 1 more week for next part.
I am not Udemy, you can checkout the full version of this course on seleniumexpress.com
@@SeleniumExpress yes sir i already checked. inr to pkr conversation for me course will be 26k pkr and I can't afford as i am a student.
@@JohnDoe-ej6vm do you have a university ICard? Give it to them, they will give you a student coupon if available. Happy Learning ❤️
In rest template - u told like it takes 10 sec to response back approximately
Is that won't happen in feign client?
Feeling good

bgm superrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
Hi Abhilash,This was a great explanation and i have a doubt what if the restService is Protected with BasicAuth ??
How to feignClient fetch the url from application. Properties file..?
understood
Can you cover unit testing cases???
Hi Deepak. I try to cover it in my 2nd batch of recordings. thank you for the suggestion.
Hi Abhilash. can you help me. I have error. It says : Consider defining a bean of type 'com.employee.employeeservice.service.AddressClient' in your configuration. It means even I make AddressClient a bean, using by @FeignClient annotation, but Spring can't find bean in IoC container. What to do?
O my God. Thanks> I resolved. Just I had to annotate main class with annotation @EnableFeignClients

What is the benefit of using client side load balancing over server side load balancing ? (I know its too early to ask) and why we are calling it client side although everything is on server ?
I have been looking into these topics from 10 days . I also have the same question . If anyone clear about this please answer
Does feign client supports spring oauth2 security features just like web client?
Yes, Kamal ! It's just a rest client.
TQ
feign client is not working for me

Thanks for the kind words ❤️
Could you please upload microservices paly list Abhilash
Hi Hari, please follow this playlist.
@@SeleniumExpress Thanks Abhilash i found play list.
Reminds me Retrofit in android development..
Can any buddy tell me which IDE is the teacher using?
STS
hi bro please upload microservices coding part in github and tell us about github account of yours.
Hi Abhilash is this course available in Udemy???
Hi Rahul. No, I am not on Udemy !
please use diffrent database
It is like Modi ji's "Man ki Baat" rather than a good tutorial . He did not look forward even once during the entire period.
thank you so much! I learnt about Feign Client and Ribbon, (load balancing)
