I hope I added the necessary dependency or do I missing anything.

I'm trying to start a new sample project using for process Kinesis Stream but I'm getting the following error:
Exception in thread "-kinesis-consumer-1" java.lang.NoSuchFieldError: logger

The sample code of Spring Cloud with Kinesis is outdated, so I tried use newest dependencies.
Anyway, someone can help?
You probably try to use the latest Spring Boot 2.4.x which brings for us Spring Integration 5.4 already. And this one is not compatible with the latest Spring Integration AWS, which is still based on the Spring Integration 5.3.x.
Let's see if you still can stick with Spring Boot 2.3.x!
Config client cannot resolve configuration property and cannot connect to config server.
Here's my service application.properties file:
spring.application.name = idmanager-service
spring.cloud.config.uri = http://localhost:8888
server.port=8081
#enable actuator endpoints
management.endpoints.web.exposure.include=*
management.endpoint.health.show-details=always
info.app.name=Id management Application
info.app.description=managing citizens identities
info.app.version=0.1.0

The config server and the discovery server started successfully and other services are successfully registered.
Here's the config server application.properties file:

The application.properties file in myConfig folder:
global=xxxxx
Other services are successfully registered and fetching config server:

I resolved this issue by fixing Spring cloud version like below:
<spring-cloud.version>Hoxton.SR3</spring-cloud.version>
Then I specified the Spring cloud dependency version using dependency management:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
I am using Spring Boot with Hystrix for my university project.
The problem I have is when I add Netflix Hystrix dependency to pom.xml file and run the program, It throws an Error called AbstractMethodError : null, but without Netflix Hystrix dependency program runs without any error. How can I slove this?
These are my dependencies
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
This is due to dependency mismatch. Application is trying to call an abstractt method but it doesn't find that method. So, it is throwing the null exception.
Use two dependency netflix-hystrix-dashboard and hystrix as below.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>

Good luck!

I lost something?

You're using an ancient version of Sleuth, can you please upgrade? Why do you provide Zipkin's version manually? Also as far as I see you're using the Sleuth's Zipkin server (that is deprecated in Edgware and removed in Finchley). My suggestion is that you stop using the Sleuth's Stream server (you can read more about this here https://cloud.spring.io/spring-cloud-static/Edgware.SR3/single/spring-cloud.html#_sleuth_with_zipkin_via_rabbitmq_or_kafka).

1) In order not to pick versions by yourself it’s much better if you add the dependency management via the Spring BOM
2) Add the dependency to spring-cloud-starter-zipkin - that way all dependent dependencies will be downloaded
3) To automatically configure rabbit, simply add the spring-rabbit dependency
