Spring Cloud Gateway unable to find microservices (404 not found) - spring-boot

I am creating a simple Hotel Review System. For me all the microservices work correctly individually.But when I try to access them using API Gateway none of them work for me.
Below are the registerd services in the Eureka Server-

Micrometer tracing does not include the trace ID in the log

I need to include traceId in the logs for the microservice application. I'm using the micrometer tracing library, but the application is not printing logs with the Trace ID.
Can someone please help me to add traceid with application logs?

Thank you for the help in Advance.
 
Add a dependency to spring-boot-starter-actuator because that's where ObservationAutoConfiguration is.

Some Properties not loaded from server

So I have been learning microservices with Spring Cloud for a while. I have correctly configured the config server but some properties like the server port and the actuator endpoints are not loaded from config repo. I am obliged to set them locally(which removes the centralized advantage of config server).
For example this is the property file in config repo for a service:
eureka.instance.prefer-ip-address= true
eureka.client.register-with-eureka= true
eureka.client.fetch-registry= true
eureka.client.service-url.defaultZone= http://localhost:8761/eureka/
server.port= 5555
management.endpoints.web.exposure.include=health,info,routes
My Bootstrap.yml for the same service:
spring:
application:
name: licensingservice
cloud:
config:
uri: http://localhost:8888
This is my pom.xml

The Eureka properties are picked up but not the server port and actuator endpoints. I have already searched for the problem but no I have not found a solution to my problem.
Please can someone help me understand why.
Thank you.

Spring boot gateway error - Unable to find RoutePredicateFactory with name path

I'm using Spring boot cloud gateway.
Spring version is 2.3.4.RELEASE
My eureka server is working well and other configurations are working well.

The problem is your predicates > path in yml file. the first letter must be a capital letter, in your case p of the path must be capital like this - Path=/client/

Problem with registering multiple instances of Zuul with Eureka. Port gets registerd as 0

I am using Zuul with Spring Boot. As I understand, in order to run multiple instances of the same application, the port number should be specified as 0 in application.yml. This way the app starts running on a random available port at startup.
I have done the same for Zuul Server app. When I start two instances of Zuul Server, both start running on random ports as expected. However the Eureka registry does not record their ports correctly. It records port number as 0.
I have used port as 0 in application.yml for my endpoint Spring Boot apps as well. Eureka has no problems registering the correct port for each endpoint instance. It is only with the Zuul Server app that the port gets registered as 0.
application.yml for the Zuul Server app
server:
host: localhost
port: 0
zuul:
routes:
foos:
path: /api/**
serviceId: endpoint
spring:
application:

eureka:

registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://localhost:8761/eureka
instance:
preferIpAddress: true
instance-id: ${spring.application.name}:${spring.application.instance_id:${random.value}}

Spring Boot Microservice cant connect to Eureka Server

I try to connect my service (auth-service) to the Eureka Server for the service registry. The Eureka server is running, but when I try to connect the auth-service nothing happens.
I added the configurations to application.yaml and application.properties, but nothing helped.
application.yaml from auth-service:

Try to use this dependency for client
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
instead of
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-netflix-eureka-client</artifactId>
<version>2.0.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-starter</artifactId>
</dependency>
Default settings should be :
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
logging.level.com.netflix.eureka=OFF
logging.level.com.netflix.discovery=OFF
As suggested by the official site.
Also, Don't forget to add #EnableEurekaServer in your main file
Source: https://spring.io/guides/gs/service-registration-and-discovery/
In the auth-service application.yaml is missing: registerWithEureka: true
eureka:
client:
registerWithEureka: true
fetchRegistry: true
registryFetchIntervalSeconds: 5
serviceUrl:
defaultZone: http://localhost:8761/eureka
instance:
preferIpAddress: true
You just put the fetchRegistry: true, which is used to record information on the client obtained from the server, to find other microservices, but not to register the client.
