Code for SpringBoot MicroServices Blog Series

How to run?

Build all modules:

spring-boot-microservices-series> ./mvnw clean package -DskipTests=true

Start infrastructure modules in docker:

The simplest way to run all the services in Docker:

spring-boot-microservices-series> ./run.sh start_all

To start only infrastructure services (mysqldb, rabbitmq, config-server, service-registry, hystrix-dashboard) in docker:

spring-boot-microservices-series> ./run.sh start_infra

Start each microservice either in local or in docker:

Local: spring-boot-microservices-series/catalog-service> ./mvnw spring-boot:run

Docker: spring-boot-microservices-series> ./run.sh start <service>

Ex: spring-boot-microservices-series> ./run.sh start catalog-service

springboot microservices gatewayservice routing issue

Environment Detail:
spring boot version 2.6.6
spring-cloud-gateway-server 3.1.1.jar

Configuration in application.properties:
spring.cloud.gateway.discovery.locator.enabled=true
spring.cloud.gateway.discovery.locator.lowerCaseServiceId=true

Port Detail:
ProductGatewayService: 5069
PssTitleService: 5071

With the above set up If I am invoking the below url I am getting proper response.
http://localhost:5069/psstitleservice/api/productService/getTitleData - working fine

In actual scenario: I am having a context path with my gateway service. /cmdgservices
With the context path, I have tried many things but none of the below way is working.

Way 1 :
spring.cloud.gateway.discovery.locator.predicates[0].name: Path
spring.cloud.gateway.discovery.locator.predicates[0].args[pattern]: "'/'+psstitleservice+'/**'"

Way 2 :
spring.cloud.gateway.discovery.locator.predicates[0].name: Path
spring.cloud.gateway.discovery.locator.predicates[0].args[pattern]: "'cmdgservices/'+psstitleservice+'/**'"

Way 3 :
spring.cloud.gateway.discovery.locator.predicates[0].name: Path
spring.cloud.gateway.discovery.locator.predicates[0].args[pattern]: "'cmdgservices/'+psstitleservice+'/**'"
spring.cloud.gateway.discovery.locator.url-expression: 'lb://'+psstitleservice

Way 4 (In Java configuration):
@configuration
public class ApiGatewayConfiguration {
@bean
public RouteLocator gatewayRouter(RouteLocatorBuilder builder) {
return builder.routes()
.route("test_route", p -> p.path("/psstitleservice")
.uri("http://localhost:5071"))
.build();
}

I have already invested 3 days behind it. I would be grateful to any helping hand. Thanks in advance.

I am getting the error mentioned here: https://stackoverflow.com/questions/51993175/org-springframework-web-client-resourceaccessexception-i-o-error-on-get-request

Could you please guide ?

Compilation error in zepkin-server project

docker-compose service starting order

Hi,

Generally, in lots of spring-boot microservices projects, also here, I see an order problem.
Before discovery service doesnt run, some other microservices gets an error "connection refused : service-registry - can not request on any server". But after a little time, generally most of services work and register successfully eureka.

Any idea?

No Docker available for Apple M1 Chip

Hi All,

I'm trying to learn more about microservices by having this project as a reference. May I use this forum for clarification? Actually No stable docker version available for Apple M1 chip, so can I execute this project in my local development system, I mean without Docker ?

Thanks,
Mohammed Sardar

Issue with containers

The inventory-service docker image is not able to connect to config-server or service-registry.
Im starting the inventory-service docker container as docker run -d -p 8282:8282 inventory-service:0.0.1 but the logs says

com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

Looks like its not able to reach the eureka server. Am I doing something wrong here?
