I have Spring Cloud config server and trying to register it to Spring Boot admin. In my pom.xml file I have
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-client</artifactId>
<version>2.1.6</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
<version>2.1.3.Release</version>
</dependency>
I have several other services registering, so I know I have all my URL and settings correct. But I am not seeing is the registering log in the config server logs.
Found the answer after running the config server in debug mode.
SpringBootAdminClientAutoConfiguration:
Did not match:
- Spring Boot Client is disabled, because 'spring.boot.admin.client.url' is empty. (SpringBootAdminClientEnabledCondition)
Matched:
- #ConditionalOnWebApplication (required) found 'session' scope (OnWebApplicationCondition)
SpringBootAdminClientCloudFoundryAutoConfiguration:
Did not match:
- Spring Boot Client is disabled, because 'spring.boot.admin.client.url' is empty. (SpringBootAdminClientEnabledCondition)
Matched:
- #ConditionalOnWebApplication (required) found 'session' scope (OnWebApplicationCondition)
Since the config server doesn't read from the config server git repo the client URL was not set.
Adding --spring.boot.admin.client.url=<url> to the startup fixed it.

I am trying to connect to AWS Aurora (Postgre) cluster from spring boot app using following properties
spring.datasource.driver.class.name = org.postgre.jdbc.Driver
spring.datasource.url=jdbc:postgresql://a2-xxxxx.cluster-xxxxxxxxxx.us-east-1.rds.amazonaws.com:5432
spring.datasource.username=username
spring.datasource.password=password
but I am getting following error -
*Caused by: java.lang.RuntimeException: Driver org.postgresql.Driver claims to not accept jdbcUrl, jdbc:postgresql://a2-xxxxx.cluster-xxxxxxxxxx.us-east-1.rds.amazonaws.com:5432

You should read the jdbc documentation.
If the host is specified, the url needs a / at the end. If the database you are connecting to has a different name than the user, you also have to put the name of the database after the /. Even if they are the same, it's a good idea to include the db name because that default behavior is a bit confusing.
Has anyone managed to configure a db2 datasource with Thorntail / Wildfly Swarm?
As far as I understand: As soon as I pull in the datasources fraction, the db2 driver should be autodetected according to documentation (https://docs.thorntail.io/2.3.0.Final/#auto-detecting-jdbc-drivers_thorntail).
So the only thing I should have to do is reference "ibmdb2" as the driver-name in my datasource, right?
pom.xml (using Thorntail 2.3.0.Final)

context:
path: /
datasources:
data-sources:
MYDS:
driver-name: ibmdb2
connection-url: jdbc:db2://host:port/schema
user-name: user
password: password
Currently I get the following error on startup:
2019-05-02 09:07:52,747 INFO [org.wildfly.swarm.datasources] (main) THORN1003: Auto-detected JDBC driver for ibmdb2
2019-05-02 09:07:57,660 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 16) WFLYCTL0013: Operation ("add") failed - address: ([
("subsystem" => "datasources"),
("jdbc-driver" => "ibmdb2")
]) - failure description: "WFLYJCA0114: Failed to load datasource class: com.ibm.db2.jdbc.DB2XADataSource"
You found a bug in the JDBC driver autodetection code. The driver was (probably) autodetected, but it was wrongly configured. Specifically, this line of code sets the XA datasource class name to com.ibm.db2.jdbc.DB2XADataSource, which doesn't exist. (That's actually what your error message says, but I also confirmed it by looking into the JDBC driver JAR.) The correct class name is com.ibm.db2.jcc.DB2XADataSource. I filed THORN-2398 and submitted a PR with a fix.
I'm not sure if there's a simple workaround, because JDBC driver autodetection is performed after all configuration is applied. Perhaps the following hack might work. Define a new JDBC driver in project-defaults.yml like this:
thorntail:
datasources:
jdbc-drivers:
mydb2:
driver-module-name: com.ibm.db2jcc
driver-xa-datasource-class-name: com.ibm.db2.jcc.DB2XADataSource
But keep everything else intact. That means there will be 2 JDBC drivers for DB2, one autodetected (which will create the com.ibm.db2jcc module), and the second one you create that will piggyback on the infrastructure created by the first. If that works, just change driver-name: ibmdb2 in your data source to driver-name: mydb2.
If this doesn't work, you'll have to move off of JDBC driver autodetection for now, until the issue is fixed.
I have developed a micro service in Spring boot and it is deployed in Cloud Foundry. MongoDB is a service created in PCF and it is a replica set type service. The mongodb service is bound to the micro service in PCF. I am using Spring cloud connector to automatically fetch the connection string for the mongodb service when deployed in cloud using the following code.
#Configuration
#Profile("cloud")
public class CloudFoundryDatabaseConfig extends AbstractCloudConfig{
#Bean
public Cloud cloud() {
return new CloudFactory().getCloud();
}
#Bean
public MongoDbFactory mongoFactory() {
return connectionFactory().mongoDbFactory();
}
}
This code is working perfectly fine when the mongoDB service is a standalone type. However if it is a replica set, i get a unknown host exception. Since the mongodb URI contains comma separated host names, it seems to be unresolved.
An example of MongoDB URI below.
"mongodb://username:password#101.23.65.41:28000,101.23.65.43:28000,101.23.65.45:28000/default?authSource=admin"
Error:

Please help.
I'm trying to set up a simple cloud stream Sink but keep running into the following errors.
I've tried several binders and they all keep giving the same error.

TL;DR - check your version of Spring Boot and try upgrading it a few minor revs.
I ran into this problem on a project after upgrading from Spring Cloud DALSTON.RELEASE to Spring Cloud Edgware.SR4 -- it was strange because other projects worked fine but there was a single one that didn't.
After further investigation I realized that the troublemaker project was using Spring Boot 1.5.3.RELEASE and others were using 1.5.9.RELEASE
After upgrading Spring Boot to 1.5.9.RELEASE things seemed to start working
I am trying to develop a spring cloud microservice using spring MVC and spring boot framework. And Eureka server , Zuul , Ribbon , hystrix and Turbine using for spring cloud. I already developed a microservice and implemented only hystrix dashboard. I am able to take hystrix dashboard. Now I am implementing more services. So I choosed turbine for aggregation of monitoring. But it not getting the dashboard.I implemented turbine in separate spring boot project.
My pom.xml containing,
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-turbine</artifactId>
</dependency>
And My main class containing,
#SpringBootApplication
#EnableHystrixDashboard
#EnableCircuitBreaker
#EnableTurbine
public class ZTurbineClientApplication {
public static void main(String[] args) {
SpringApplication.run(ZTurbineClientApplication.class, args);
}
}
And my Turbine project application.properties file containing,
server.port=8085
spring.application.name=espace-Turbine
eureka.client.serviceUrl.defaultZone=http://localhost:8071/eureka/
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true
turbine:
aggregator:
clusterConfig: APPCLUSTER
app-config: espaceService1,espaceService2
instanceUrlSuffix.APPCLUSTER: /hystrix.stream
And My previous first services's application.properties file like
eureka.client.serviceUrl.defaultZone=http://localhost:8071/eureka/
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true
spring.application.name=espaceService1
server.port=8080
eureka:
instance:
prefer-ip-address: true
leaseRenewalIntervalInSeconds: 3
leaseExpirationDurationInSeconds: 3
metadata-map:
cluster: APPCLUSTER
And second service's application property file contains,
eureka.client.serviceUrl.defaultZone=http://localhost:8071/eureka/
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true
spring.application.name=espaceService2
server.port=8081
eureka:
instance:
prefer-ip-address: true
leaseRenewalIntervalInSeconds: 3
leaseExpirationDurationInSeconds: 3
metadata-map:
cluster: APPCLUSTER
these are my implementation details.
After I took URL "http://localhost:8085/hystrix.dashboard". And pasted "http://localhost:8085/turbine.stream?cluster=APPCLUSTER". But getting error like "Unable to connect to Command Metric Stream". Adding screenshots below.
You need to remove space from comma separated service names
turbine.aggregator.cluster-config=espace-Second_Microservice,espaceFirst_Microservice
You cannot aggregate streams from different cluster names, either use one cluster name in both espace-Second_Microservice and espace-First_Microservice or don't use cluster at all.
To define one cluster name use below config
eureka:
instance:
prefer-ip-address: true
leaseRenewalIntervalInSeconds: 3
leaseExpirationDurationInSeconds: 3
metadata-map:
cluster: APPCLUSTER
Use below mentioned config for turbine
turbine:
aggregator:
clusterConfig: APPCLUSTER
app-config: espace-Second_Microservice,espace-First_Microservice
instanceUrlSuffix.APPCLUSTER: /hystrix.stream
Use http://{turbine host}:{turbine Port}/turbine.stream?cluster=APPCLUSTER in Hystrix Dashboard
