Chapter 16 is not working...

[tintachina84]

Hello.

I'm learning microservice via this contents. Thanks.

I have stepped chapter 16 but it's not working. Problem is that core microservices can't get common properties in config-repo.

I thoght I got miss something, so built your code directly but not different.

For example, if I requests config properties to config-server in Chapter14, docker exec 722feaa1c331 curl -v http://dev-usr:dev-pwd@localhost:8888/review/docker result is {"name":"review","profiles":["docker"],"label":null,"version":null,"state":null,"propertySources":[{"name":"Config resource 'file [/config-repo/review.yml]' via location 'file:/config-repo/' (document #1)","source":{"spring.config.activate.on-profile":"docker","server.port":8080,"spring.datasource.url":"jdbc:mysql://mysql/review-db"}},... propertySources is not empty.

But in Chapter16, docker exec 05e9473ea07b curl -v http://dev-usr:dev-pwd@config-server:8888/review/docker result is {"name":"review","profiles":["docker"],"label":null,"version":null,"state":null,"propertySources":[]}

So all core component can't be available because they couldn't get @Value component.

This is product-composite log: $ kubectl logs deploy/product-composite

Should I change java version to 17?

[magnus-larsson]

Hello, and thanks for reporting this problem!

I have noticed various problems with Java 21 and Spring Boot 3.1, so I recommend to revert back to Java 17 since it is used in the book.

Let me know if that resolves your issue!

Hello, again. Sorry, my bad. I made a mistake on having symbolic link. All container is running now. But gateway is not listening to my requests when I did this. curl -k https://localhost:30443/actuator/health I think NodePort setting is something wrong. Anyway this is another problem and I'll take this. Thank you!

Great! please file new issues if you get stuck on other problems!
