I am going to register my spring boot application to spring-boot-admin server.
Here is my SpringBootAdminApplication.java
#Configuration
#EnableAutoConfiguration
#EnableAdminServer
public class SpringBootAdminApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootAdminApplication.class, args);
}
}
And pom.xml:
<dependencies>
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-example</artifactId>
<version>1.0.5</version>
</dependency>
</dependencies>
and application.properties
server.port = 8080
Server is running now:
Now, in client side:
properties:
spring.boot.admin.url=http://localhost:8080
info.version=#project.version#
spring.application.name=rest-module
pom.xml:
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-client</artifactId>
<version>1.3.0</version>
</dependency>
But, when i run the spring boot from client, i get this error:
Created POST request for "http://localhost:8080/api/applications"
Setting request Accept header to [application/json, application/json, application/*+json, application/*+json]
Writing [Application [id=null, name=rest-module, managementUrl=http://Hayatloo-PC:8082, healthUrl=http://Hayatloo-PC:8082/health, serviceUrl=http://Hayatloo-PC:8082]] as "application/json" using [org.springframework.http.converter.json.MappingJackson2HttpMessageConverter#1637320b]
Failed to register application as Application [id=null, name=rest-module, managementUrl=http://Hayatloo-PC:8082, healthUrl=http://Hayatloo-PC:8082/health, serviceUrl=http://Hayatloo-PC:8082] at spring-boot-admin (http://localhost:8080/api/applications): 400 Bad Request
Why id=null ?
You messed up the versions. Try to update the client and server to the same versions. We try too keep em compatible but from 1.0.x to 1.3.x you have no chance.
Btw current version is 1.3.2.
Additional you are using the sample as dependency. This indeed works, but I wouldn't recommend it. You better setup your server as described in the guide. http://codecentric.github.io/spring-boot-admin/1.3.2/

I am trying to migrate my springboot application written in kotlin to azure.
I added spring-cloud-azure-starter-keyvault-secrets:4.5.0 dependency in my app, and added below configurations to application.properties.
my.secret=${my-azure-secret}
spring.cloud.azure.keyvault.secret.property-source-enabled=true
spring.cloud.azure.keyvault.secret.property-sources[0].endpoint=<my-vault>.vault.azure.net/
After I add this, the spring boot initialization doesn't work any more and i can't find any logs.
log.info { "Log before springboot initialize" }
SpringApplication(MyApplication::class.java).run(*args)
log.info { "Log after springboot initialize" }
So, Log before springboot initialize is logged, and after that nothing happens (or I can't find any logs afterwards)
I already verified it is not related to any logback settings because if I remove the property spring.cloud.azure.keyvault.secret.property-sources[0].endpoint from application.properties, it boots up properly.
(I also tried to add the additional dependency spring-cloud-azure-dependencies:4.5.0 )
Any clues/hints what is happening and how to resolve it ?
Thanks.
Here I was able to boot the spring application using the same dependencies.
But here I used the latest version of spring-cloud-azure-starter-keyvault-secrets i.e. 5.0.0 also my spring boot version is 3.0.2
my dependencies:
<dependencies>
<dependency> <groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency> <!-- https://mvnrepository.com/artifact/com.azure.spring/spring-cloud-azure-starter-keyvault-secrets -->
<dependency>
<groupId>com.azure.spring</groupId>
<artifactId>spring-cloud-azure-starter-keyvault-secrets</artifactId>
<version>5.0.0</version>
</dependency>
<dependency> <groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency></dependencies>
Also I use windows so instead of my_azure_secret instead of the my-azure-secret
output:
I am using "Spring Boot - 2.1.5.RELEASE" and "Spring framework - 5.1.7.RELEASE".
JMS listener annotation is not picking a message from a MQ queue. No error logs are rolling in my IntelliJ IDEA as well.
About my project - I am exposing a REST service which sends and receives a message from MQ (used JMSTemplate annotation). Till now it was working. Now I have to add another class which should listen for a queue. Hence added #JMSListener annotation which is not picking any message. Any insight will be really helpful.
The pom has below specified dependencies.
<dependency>
<groupId>com.ibm.mq</groupId>
<artifactId>mq-jms-spring-boot-starter</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
</dependency>
<dependency>
<groupId>com.ibm.mq</groupId>
<artifactId>com.ibm.mq.allclient</artifactId>
<version>9.1.4.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jms</artifactId>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>
The class has below specified method.
import org.springframework.jms.annotation.JmsListener;
#Component
public class PickMyMessage {
#JmsListener(destination = "IN",containerFactory = "myFactory")
public void pullMyMessaage(String message){
System.out.println("Message is pulled..");
}
}
My main application has #EnableJMS annotation. In my application.yml file I have given below information.
ibm:
mq:
channel: MY.APP.SVRCONN
connName: 192.168.0.1(1415)
password: Pswd
queueManager: QM01
user: appsrv
My Bean class configs are
My JMS connection factory as below.
#Bean
public JmsListenerContainerFactory<?> myFactory(ConnectionFactory connectionFactory,
DefaultJmsListenerContainerFactoryConfigurer configurer) {
DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
configurer.configure(factory, connectionFactory);
}
Not sure what else I am missing here. Any insight will be really helpful.
Instead of my existing project, if i create any simple demo project it is working as expected.
The class PickMyMessage is not a Spring bean, that's why Spring ignores it. Declare it as a #Bean or as a #Component.
May be there are further problems. But this is the first one that needs to be resolved.
I am unable to get the value I am expecting, An exception is thrown at this line #Value("${message:this-is-class-value}").

Please do let me know if anything else is required.
add message=Hello from property file1 in src/main/resources/application.properties. Or if you want to read this property from c:/config/application.properties or c:/config/config-service.properties you need to configure external configuration file by using #ConfigurationProperties annotation.
Looks, you are trying to use the #Value annotation on controller class which resides in your Cloud config server application. While the concept is like cloud config server application will be the provider to other applications and it can provide the properties from git or local file system (configuration) to requester client application. Other applications will connect to your config server application by providing it's URL, application name and profile for which it want to get the properties. You can check below URL for cloud config server and client application.
https://www.thetechnojournals.com/2019/10/spring-cloud-config.html
Your cloud config server has security configuration as below.
spring.security.user.name=root
spring.security.user.password=abc123
You client configuration doesn't provide any security configuration which is causing 401 error in your logs.
To solve this issue please do below changes to your client configuration.
Client configuration:
spring:
profiles:
active: PROD
cloud:
config:
name: api-gateway
uri: http://localhost:8888/
username: root
password: abc123
I want to setup the Keycloak adapter (v7.0.0) for a Spring Boot 2.1.x backend. Somehow this doesn't work as expected and mvn clean spring:boot-run shows errors.
To get a playground i cloned this working repo. After a successful build with the old versions of Keycloak and Spring Boot i changed the dependencies (and versions).
For the POM i included:
<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-spring-boot-starter</artifactId>
<version>7.0.0</version>
</dependency>
and
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.keycloak.bom</groupId>
<artifactId>keycloak-adapter-bom</artifactId>
<version>7.0.0</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
and provide properties via the application.yml file:
keycloak:
auth-server-url: http://127.0.0.1:8081/auth/
resource: persons-app
realm: PersonRealm
public-client: true
principal-attribute: preferred_username
This follows Keycloaks docs.
The result is an error showing:
Description:
Parameter 1 of method setKeycloakSpringBootProperties in org.keycloak.adapters.springboot.KeycloakBaseSpringBootConfiguration required a bean of type 'org.keycloak.adapters.springboot.KeycloakSpringBootConfigResolver' that could not be found.
Action:
Consider defining a bean of type 'org.keycloak.adapters.springboot.KeycloakSpringBootConfigResolver' in your configuration.
This is already defined. So thats the problem. I don't know if there are certain restriction of what versions of Keycloak and Spring Boot work together. Maybe someone could explain what i missed here or what versions to set. Thanks!
The same question has been asked here: Issues running example keycloak spring-boot app I'll point you to the other one for more information about the issue and a temporary workaround.
At the moment there is no ultimate solution, it's an issue with the Keycloak Spring Boot Adapter 7.0.0. If you use the previous version of the adapter (6.0.1) then it will work fine, even if the Keycloak server is running version 7.0.0 (you just don't get the new features introduced in the new adapter).
I am following Jersey tutorial to develop simple Jersey web application.
By following Section - Example 2.9. Deployment of a JAX-RS application using #ApplicationPath with Servlet 3.0
I have created created below program:
#ApplicationPath("resources")
public class MyApplication extends PackagesResourceConfig {
public MyApplication() {
super("com.examples");
}
}
and I have below basic Resource class:
#Path("/helloworld")
public class HelloWorldResource {
#GET
#Produces("text/plain")
public String getClichedMessage() {
return "Hello World";
}
}
I am using Jersey-1.19 version, I am not having any web.xml file in my web application. Now I am deploying my application on Tomcat 7 server.
When I try to access the URL as : http://localhost:8080/myapp/resources/helloworld I am getting error as
HTTP Status 404 - /myapp/resources/helloworld
type Status report
message: /myapp/resources/helloworld
description: The requested resource is not available.
You need the jersey-servlet dependency
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-servlet</artifactId>
<version>1.19</version>
</dependency>
if you want to go with no web.xml. It has the JerseyServletContainerInitializer required to load the application.
And just for any future readers that come across this looking for a Jersey 2.x solution, you need the following dependency to work with no web.xml
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>
<version>${jersey2.version}</version>
</dependency>
for the same reason - it has the JerseyServletContainerInitializer
