I'm using this Camel example as a reference and changed the Initializer to extend SpringBootServletInitializer so that I can deploy to JBoss EAP 6.4.
When running this as a SpringBoot application:
The Spring Actuator endpoints like /info work. /health even returns the health of the Camel Context, however Camel Actuator endpoints like /routes return http 404.
When deploying to JBoss:
None of the actuator endpoints work. They all return http 404.
The problem is not unique to the demo, all of our Containerized Camel Spring Boot Applications running in JBoss have this same problem, and to be clear, these applications are entirely functional otherwise.
bootstrap.yml
camel:
springboot:

health:
check:
routes:
enabled: true
indicator:
enabled: true
endpoints:
actuator:

Looks like new spring cloud version of netflix has some issues.I am trying to run eureka server locally and trying to register to it and i see the following exception.I thought spring boot will pull all dpendencies.
Here is the exception:

I dont find any one reporting this issue Please help
You need add dependency:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
I work on app in which I try to register Eureka client on server but stuck on the first step where I need dependency which make enable #EnableEurekaClient annotation.
I followed cloud.spring.io instructions which did not work:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
II) I then found some latest stack & tried (as follows) which did not work as well:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
I wonder, as all folder suddenly disappear in case I put above dependency in the pom.xml (I use Intellij)

You need to add the Spring Cloud BOM to your pom.xml as follows:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>2020.0.3</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
Once this is added, all Spring Cloud dependencies including spring-cloud-starter-netflix-eureka-client will resolve, and you should be able to use annotations such as #EnableDiscoveryClient for activating the Eureka discovery client.
I am trying to connect a Postgres DB to my Spring Boot aplication, but I get the following error:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
application.yaml
datasource:
driver-class-name: org.postgresql.Driver
url: jdbc:postgresql://localhost:5432/my_db

You appear to be missing the spring prefix from all of the properties in your application.yaml. It should be the following:
spring:
datasource:
driver-class-name: org.postgresql.Driver
url: jdbc:postgresql://localhost:5432/my_db
username: postgres
password: pswrd
# JPA properties
jpa:
hibernate:
ddl-auto: update # When you launch the application for the first time - switch "none" at "create"
show-sql: true
database: my_db
database-platform: org.hibernate.dialect.PostgreSQLDialect
open-in-view: false
generate-ddl: true
I have a config server and spring boot microservices running with config server requiring basic authentication user/pw. I have a Keycloak server I want to use for authentication and authorization of the microservice to the config server.
I have added the keycloak spring boot adapter to the config server so now the config server requires an OAuth2 token and have verified with Postman that it works as expected.
This is my microservice pom

secrets defined in AWS as
/secret/context-name/val1 [foo:bar]
/secret/context-name/val2 [wibble:wombat]
The underlying code in AwsSecretsManagerPropertySource seems to look for the actual secret at the following
/secret/context-name
/secret/context-name_
/secret/service-name
/secret_service-name_
only, so never finds the secret at /secret/context-name/X
Is this expected behaviour ? if so, how would I define multiple secrets in bootstrap.yml ?
you can define your custom(not read by spring by default) secret name via
spring:
config:
import: optional:aws-secretsmanager:{secret arn}
or via
spring:
config:
import: optional:aws-secretsmanager:{/secret/shortName}
when spring boot application boots up, it usually read and load secrets in the environment from these secrets
/prefix/application
/prefix/{your-application-name}
in addition with what you defined via spring.config.import
you can read more about it from here
For me below configuration in bootstrap.yml worked
spring:
application:
name: AwsSecretManager
aws:
secretsmanager:
prefix: /secret
defaultContext: service
profileSeparator: _
failFast: true
name: AwsSecretManager
enabled: true
cloud:
aws:
stack:
auto: false
region:
use-default-aws-region-chain: true
credentials:
use-default-aws-credentials-chain: true
Properties defined in AWS as below
Secret name: /secret/AwsSecretManager_dev
Here dev denotes the profile for which the properties are defined.
Note:
The configuration defined in bootstarp.yml is just a sample configuration for only the Secret manager service and does not make use of AWS stack. The properties will vary based on requirement.
