I have seen most of video of microservices and the way you explain is quite easy to understand and it added more flavour by doing in practical.. Awesome.. 👍👍👌👌
Hi @Java Techie, I just tried this implementation and it worked after remove ribbonRule() method from configuration otherwise gave error no chatbook instances are running.
Thank you so much for the informative video!!! In the last part of the video, you mentioned if we use eureka we can do load balancing by adding @LoadBalanced to restTemplate method, without using RibbonConfiguration. So why do we really need Spring Cloud Ribbon, if we can just do with Eureka?
Hi Subin, if you are directly using eureka then ribbon implementation is inbuilt in nature all required configuration stuff already preconfigured in eureka
why we need to do this？in this case，i think we may had twice request，first request to ribbon-server，second request is that ribbon-server to final-sever ，and then，final-sever response to ribbon-server，ribbon-sever response to client？is this slow down the web request speed？twice request ，double traffic？i was confused and i thought this is not make sense
Regarding IPing and IRule Beans: you passed an argument IClientConfig which you did not use within Bean method. so is it necessary to pass it? please help me understand I'm new to Spring Boot BTW your videos are extremely helpful. Thank you so much.
Thanks Deep , hey already I uploaded video related hystrix please Go through below link th-cam.com/video/2x9G8daUM8A/w-d-xo.html th-cam.com/video/A2IhEwbniLI/w-d-xo.html
The concept of load balancing is very well explained in the video. Can you suggest how to implement the same for POST, DELETE. Also in real time application there can be n number of end points so how to handle those?
Hi Sir, I was getting "No instance found for chatapp" error. Eventually, I had to remove ribbonRule method from RibbonConfiguration class for it to work. Not sure why.
First of all, thank you very much, sir. I have a question. I want to build a micro-service based e-commerce web application. suppose, I have some services, like customer service, product service(only contain Title and description and the image & price fetches IMG & price from another IMG service & price service), order service, and cart service. In my product service, It is possible when I have static data. and I have tried it. But my question is how can I add a new product record (with all fields) from the admin service(admin panel) into the multiple services like IMG service, product service(Title and description), price service? Please make a video on how to add records into multiple services at a time?
Hi Team, I follows the all steps which sir explain. while running apps getting below error.

Nice job , thanks and keep it up ............. You have suggested some changes like "template.getForObject("chatbook/chat" , String.class);" ...... Some guy online suggested remove @Bean annotation for IRule in config so i did and it worked .... of course dont know why :-) RibbonConfiguration.java ......... // @Bean -------------->Remove annotation public IRule rule(IClientConfig iClientConfig){ return new AvailabilityFilteringRule(); } ......... Hope it helps ....
getting error saying "local instance not found for the list of servers". finally after commenting the below code in RibbonConfiguration it worked fine. @Bean public IRule ribbonRule(IClientConfig config) { return new AvailabilityFilteringRule(); } Anything wrong in using IRule?

Hi Umar, please remove root url from ChatbookApplication which i wrote on top of class i wrote @RequestMapping("/chatbook-application") and remove the same URL while invoke from user-app controller and use like this template.getForObject("chatbook/chat" , String.class); don't know why it behaving like this now , what i understood previously we wrote like template.getForObject("chatbook-application-chatbook/chat" , String.class); right ? so chatbook is our application which we mapped in multiple port but spring boot looking a service with name chatbook-application/chatbook so that's what the problem ..

@@Javatechie i try the same method showed in the video but when i use server.port= 8001 and other, its taking the last port only not showing the result on other port as the reason is that i am running that application and the port which is mentioned in the application (the last port) will be running not other ports will run as they are off.

Can't find the ribbon dependency to add. Should I change the java version or spring version.
Change spring version

Nice job , thanks and keep it up .............
You have suggested some changes like "template.getForObject("chatbook/chat" , String.class);" ......
Some guy online suggested remove @Bean annotation for IRule in config so i did and it worked .... of course dont know why :-)
RibbonConfiguration.java
.........
// @Bean
-------------->Remove annotation
public IRule rule(IClientConfig iClientConfig){
return new AvailabilityFilteringRule();
}
.........
Hope it helps ....
In one of the comment I shared alternative solution please have a look
Hi Basant,
I am not able to run these examples in new version of STS4 please share the old STS4 link if you have
PLease share us the updated video, for client side load balancing example
Okay will do once more
Suppose if I have many apis like /chat in loadbalancer app.. Then how many /invoke api needs to write in client app?
Nice explanation
What if i dont specify the ports of instances using server.port: 0 and let spring decide the port no for me ?
getting error saying "local instance not found for the list of servers". finally after commenting the below code in RibbonConfiguration it worked fine.
@Bean
public IRule ribbonRule(IClientConfig config) {
return new AvailabilityFilteringRule();
}
Anything wrong in using IRule?
Which version of spring boot are you using ?

Am not sure then as I already mentioned based on enhance version the implementation might changes

nice
How to set 3 ports?
Change in application.properties and start it
But, if we first run it on port 8001 then 8002 then 8003. So in my case it's working on 8003 port only. Not on other port numbers.
