I want to use spring consul integration but it always uses eureka. Could somebody help me? I guess problem is with maven dependencies.
I have next maven file:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

It is right maven dependencies:
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-consul-all</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-consul-discovery</artifactId>
</dependency>
</dependencies>
in your pom file you use below dependency. it use for discover your app for eureka.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
change this dependency to below dependency.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-consul-discovery</artifactId>
</dependency>

When I m going to add spring-cloud-starter-netflix-hystrix dependency into pom.xml file, the build was failed.

Errors says you are missing version for org.springframework.cloud:spring-cloud-starter-netflix-hystrix. You can declare appropriate version under <properties> section something like (I am using latest version for example, you can use any appropriate version here) :
<properties>
..
<spring-cloud-starter-netflix-hystrix.version>2.2.10.RELEASE</spring-cloud-starter-netflix-hystrix.version>
</properties>
& inside dependency tag:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
<version>${spring-cloud-starter-netflix-hystrix.version}</version>
</dependency>
I used resilience4j circuitbreaker instead of hystrix. I worked as I expected in API-gateway service.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-circuitbreaker-reactor-resilience4j</artifactId>
</dependency>
I got two modules under parent project. 'store-commons' (which contains common code) and 'catalog-service'. catalog have included commons as a dependency. In my Intellij, when I expand the dependencies, I see only some of the dependencies specified in commons get imported into catalog (eg h2 DB and hibernet validator) but some doesn't (eg lombok). I wonder what is the rational behind it? In this case I've to add lombok as a dependency in my catalog POM for code to build. Please find attached image for more details

Im try to create a simple project with 2 application ( a simple rest app and a config-server app )
My config-server project is ok, because if I got http://localhost:9091/form-create/container I can see all vars from form-create.properties
but my application form-create is not getting properties from config-server
here is my bootstrap.properties in form-create project
spring.application.name=form-create
spring.cloud.config.uri=http://localhost:9091
spring.cloud.config.fail-fast=true

#SpringBootApplication
public class MsFormCreateApplication {
public static void main(String[] args) {
SpringApplication.run(MsFormCreateApplication.class, args);
}
}
What am I doing wrong? if I start my form-create application is starting on 8080 port and not getting properties from config server.
I think you should try to check two things:
Your maven dependencies. It looks like you've put them wrong, namely, if you're running cloud config client, why do you have a dependency for spring-cloud-config-server?
For Web and cloud config client the following list is sufficient:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<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>
When you start the config server, are you sure that it indeed reads the configuration from the repository you've configured (git, file system, whatever)?
In general it exposes REST API so you can curl the server to get the information even without starting the spring boot application
Try that and make sure that it works as expected. For example, read this part of tutorial. Note that you might have put the configuration for different profile or different branch, cloud config server can handle that, but you'll have to specify profile for example in the bootstrap.properties.
I follow Spring Tips: Spring Cloud Gateway. But my gateway app doesn't create routes from the service register(Eureka). DiscoveryClientRouteDefinitionLocator constructor with 2 params. The gateway app it's not routing from Eureka server. I've been trying changing the versions in the pom.xml but I'm using the RELEASE.
The Application.java
#SpringBootApplication
public class GatewayApplication {
#Bean
DiscoveryClientRouteDefinitionLocator discoveryRoutes(DiscoveryClient dc, DiscoveryLocatorProperties dlp) {
return new DiscoveryClientRouteDefinitionLocator(dc, dlp);
}
public static void main(String[] args) {
SpringApplication.run(GatewayApplication.class, args);
}
}
The constructor of the DiscoveryClientRouteDefinitionLocator is using now 2 params instead just 1 like in the Spring Tips: Spring Clou Gateway.
The application.property:
spring.application.name=gateway
server.port=8081
eureka.client.register-with-eureka=true

To let it works. You don't need to add the bean below, remove it
#Bean
DiscoveryClientRouteDefinitionLocator discoveryRoutes(DiscoveryClient dc, DiscoveryLocatorProperties dlp) {
return new DiscoveryClientRouteDefinitionLocator(dc, dlp);
}
In your application.properties, add these two lines to enable discovery client
spring.cloud.gateway.discovery.locator.enabled=true
spring.cloud.gateway.discovery.locator.lower-case-service-id=true
And it should work!
The constructor DiscoveryClientRouteDefinitionLocator(DiscoveryClient, DiscoveryLocatorProperties) is deprecated
I suggest you to use :
ReactiveDiscoveryClient instead of DiscroveryClient
#Bean
DiscoveryClientRouteDefinitionLocator discoveryRoutes(ReactiveDiscoveryClient rdc,
DiscoveryLocatorProperties dlp) {
return new DiscoveryClientRouteDefinitionLocator(rdc, dlp);
}
Other thing, you should rename your application.proporty to application.properities
