Would you know how I could convert this project to reactor? I tried over the weekend but failed.

Lab 3 - Could not resolve placeholder 'lucky-word' in string value "${lucky-word}"
I used all the server and client source files provided in Lab 3 or type all the sources from the video.
Having an issue trying to get the client to run. (Server starts fine).
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'luckyWordController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: java.lang.String com.example.LuckyWordController.luckyWord; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'lucky-word' in string value "${lucky-word}"

What am I doing wrong?
Issue in Server replica in Eureka
I have started 3 eureka servers and mentioned eachother in application.yml's serviceUrl.DefaultZone.
Still when i start 3 servers ( irrespective of simultaneous start or one after another) they fail to register to eachother and I get lot of errors
Lab 3: Client does not include spring-boot-starter-web dependency required for lab
The lab for creating the spring config client Rest service does not include adding the dependency for:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
This is described in the lecture slides but not in the lab instructions in order to create a Tomcat server and REST endpoint in order to display the lucky-word pulled from the config server.
Symptom: Spring boot application starts and stops immediately as it is a console application not web and does not contain any of the embedded Tomcat libraries.
Note: It is correctly included in lab3-client-solution.
Getting cold words only...
Hi,
I'm sure I'm doing something wrong, but until now I've spent too many hours for this. When I follow the steps of Lab 5, and I start the second noun - word-server (Step 15) I get only cold words like this:
Some Sentences
blizzard icicle icicle blizzard blizzard.
blizzard blizzard blizzard refrigerator blizzard.
blizzard blizzard blizzard blizzard blizzard.
blizzard blizzard blizzard blizzard blizzard.
blizzard blizzard refrigerator blizzard icicle.
I guess somehow setting the hard coded string to words, overwrites all running instances (which I really don't get).
First I had this problem by using the IntelliJ IDE, then I downloaded STS and the same problem occurs. Could somebody please give me a hint on this one?
Thanks a lot!
Guide doesn't support java 11+
I was unable to run lab4 guide with latest spring boot atm(2.2.1.RELEASE) and java 11. Even if I add jaxb dependencies here is the cause
...Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'traceFilterRegistration' defined in class path resource [org/springframework/cloud/netflix/eureka/server/EurekaServerAutoConfiguration.class]: Unsatisfied dependency expressed through method 'traceFilterRegistration' parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.servlet.Filter' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Qualifier(value="httpTraceFilter")}...
After I downgrade spring boot to 2.1.10.RELEASE and added JAXB
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>

</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.3.1</version>

it worked out.
Lab4: Eureka Server start fails with java.lang.NoClassDefFoundError
Hi,
Following the instructions for Lab-4, I run into the bellow error. Tried adding the dependency package where the class is located without luck.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-commons</artifactId>
</dependency>
Any ideas? Thanks!

@RestResource not working with Spring 1.4.1-Release
Hi. I've been watching your examples. If you download a Starter Proyect from spring.starter.io, it cames with Spring Boot 1.4.1; so when try to use @RestResource in TeamRepository interface, package was not valid.
Is there any update to use with Spring Boot 1.4.1, instead of 1.3.5?
Thanks,
step 27 is not working in lab 4 readMe
Below is the current instruction for step 27 in lab 4.
https://github.com/kennyk65/Microservices-With-Spring-Student-Files/blob/master/LabInstructions/Lab%204.md
If you like, you can experiment with moving the “words” properties to the GitHub repository so they can be served up by the config server. You’ll need to use separate profile sections within the file (yml) or files with names that match the application names (yml or properties). A single application.yml file would look something like this:
---
spring:
profiles: subject
words: I,You,He,She,It
---
spring:
profiles: verb
words: ran,knew,had,saw,bought
---
spring:
profiles: article
words: a,the
---
spring:
profiles: adjective
words: reasonable,leaky,suspicious,ordinary,unlikely
---
spring:
profiles: noun
words: boat,book,vote,seat,backpack,partition,groundhog
I tried this for sometime but it did not work. It is possible I am doing something wrong. I did some trouble shooting. but a few questions arose.
- In the above
application.yml, profiles are environment specific. As you demonstrated, one can have different profiles for a single application such as dev, qa, stage, prod etc.
But what you have defined above is the name of application.
Clients retrieve configuration metadata from config server using name of the application.
For eg: an application with name "lab3-client" and profile "dev" will merge the following the config files in the order:
application.yml < lab3-client < lab3-client-dev
so one could access the config metadata using
http://localhost:8001/lab3-client/dev
I am thinking we would still individual configuration files for each clients.
i.e) lab4verb.yml (name of application + within this file, different profile can be configured)
lab4noun.yml
lab4adjective.yml etc
please correct me if I am wrong.
Thanks for great tutorial and looking forward to more on Spring security and Spring OAuth

Having an issue trying to get the client to run. (Server starts fine).

step 25 in lab 4 ReadMe needs update
Currently step 25 does NOT instruct to add the cloud-config-client dependency in pom.xml. without this, client applications does not communicate with config server. The following lines should be added to each of client application's pom.xml
```
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-client</artifactId>
</dependency>
```
Thank you for the excellent course in Udemy. Really enjoying it and doing all the labs.
