I am using springdoc-openapi-starter-webmvc-ui dependency and spring boot version is 3.0.2 with JDK 17 but when I am hitting http://localhost:8080/swagger-ui/index.html its showing default petstore API not my application API..
Below are the dependencies which I am using :
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
<version>2.0.2</version>
<exclusions>
<exclusion>
<artifactId>org.webjars</artifactId>
<groupId>swagger-ui</groupId>
</exclusion>
</exclusions>
</dependency>
<!-- https://mvnrepository.com/artifact/org.webjars/swagger-ui -->
<dependency>
<groupId>org.webjars</groupId>
<artifactId>swagger-ui</artifactId>
<version>4.8.1</version>
</dependency>
and in application.yaml
springdoc:
swagger-ui:
path: '/swagger-ui.html'
disable-swagger-default-url: true
but it seems disable-swagger-default-url is not working in this case. Please let me know how can I get rid of this default petstore api and able to hit my application api.

I am migrating from open tracing to open telemetry with jaeger.
Earlier the pom had following:
<dependency>
<groupId>io.opentracing</groupId>
<artifactId>opentracing-api</artifactId>
<version>0.31.0</version>
</dependency>
<dependency>
<groupId>io.opentracing.contrib</groupId>

</dependency>
<dependency>
<groupId>io.jaegertracing</groupId>
<artifactId>jaeger-client</artifactId>
<version>0.31.0</version>
</dependency>
Then I migrated from java 8 spring boot v2.3 to java 17 spring boot v3. So I updated the config as follows:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-sleuth</artifactId>

<version>1.14.0</version>
</dependency>
<dependency>
<groupId>io.grpc</groupId>
<artifactId>grpc-okhttp</artifactId>
<version>1.51.0</version>
</dependency>
the properties are mentioned below:
<java.version>17</java.version>
<spring-boot.version>3.0.0</spring-boot.version>
<spring-cloud.version>2021.0.5</spring-cloud.version>
<spring-cloud-sleuth-otel.version>1.1.0</spring-cloud-sleuth-otel.version>
<opentelemetry-exporter-otlp>1.20.1</opentelemetry-exporter-otlp>
The problem I encounter is that the spans are not logged. I do not see any logs that say span reported, which I usually get before. I haven't connected this to any collector or added any telemetry related configuration. I was following this tutorial () but it says the app should work out of the box.
What kind of configurations am I missing here?
EDIT: The second approach (The open telemetry one) works when spring boot version is 2.5.6 (https://qdnqn.com/opentelemetry-spring-boot-kafka-and-jaeger-in-action/) but not when 3.0. How can make this work in spring boot 3?
I wanted to swap out the deprecated High Level Rest Client with the new Java API Client from Elasticsearch. Problem is, I'm not sure if my dependencies are configured correctly! I'm running into this error:
java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/util/JacksonFeature
Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.core.util.JacksonFeature
Elasticsearch just got upgraded to 7.17.3 and Spring Boot is 2.2.8 right now, it will be upgraded later but I'm not sure if that's the problem? Here are my dependencies in the pom:

I followed the documentation from Elasticsearch here so I tried it with the 2.12.3 version of jackson-databind as well but the error persists. Any idea on what should be changed? Thanks!
Edit: just in case it helps, here's also my client which is where the dependency is needed (I assume)
#Configuration
public class ElasticsearchClient{
RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200)).build();
ElasticsearchTransport transport = new RestClientTransport(restClient, new JacksonJsonpMapper());
public ElasticsearchClient client = new ElasticsearchClient(transport);
}
(I had to put the public in front of client because it sits under another package and won't let me call on it unless it's there)
more info after playing around: turns out there is a parent and it would load an older jackson-databind, so I did the following
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-schema-registry-client</artifactId>
<exclusions>
<exclusion>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.12.3</version>
</dependency>
still doesn't work so I'm 200% out of ideas now
Add jackson-core solved my problem.
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.12.3</version>

I have a spring cloud microservices project which uses Spring Cloud Config Server for managing configurations and Eureka Server for service discovery.
My application was doing great until I wanted to add a new microservice with keycloak. This new microservice is simply a rest API for my Vue frontend application and user managament is expected to be handled by Keycloak.
The new service runs OK and registers itself to Eureka until I add keycloak dependencies to the project. Application does not crash or throw any errors, startsup fine and registers itself to Eureka but on the Spring Boot Admin server panel I see that the application is down.
Here is my .properties file for the new service.
eureka.instance.preferIpAddress=true
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka
eureka.instance.leaseRenewalIntervalInSeconds=3
eureka.client.eureka-connection-idle-timeout-seconds=3
eureka.client.fetchRegistry=true
spring.boot.admin.client.url=http://localhost:6060

keycloak.public-client=true
keycloak.security-constraints[0].authRoles[0]=user
keycloak.security-constraints[0].securityCollections[0].patterns[0]=/*
keycloak.cors=true
Here are my dependencies for the new service.

Spring cloud version is Hoxton.SR1
Spring boot version is 2.2.2.RELEASE
I have tried adding Spring Security and making java configurations using KeycloakAuthenticationProvider but didn't help.
Throughout this project, I had many weird bugs caused by Spring Cloud version or Spring Cloud-Spring Boot Admin interaction so changing version or adding one little parameter to the configuration files usually did the trick, I am suspecting this Keycloak issue will be solved the same way.
Spring Boot Admin uses actuator endpoints, try to make them unprotected:
keycloak.security-constraints[0].authRoles[0]=user
keycloak.security-constraints[0].securityCollections[0].patterns[0]=/*
keycloak.security-constraints[0].securityCollections[1].patterns[0]=/actuator
keycloak.security-constraints[0].securityCollections[1].patterns[1]=/actuator/*
Versions:
Spring Boot 2.1.0
Spring Boot Admin 2.1.1
I have everything working with my Spring Boot app reporting to Spring Boot Admin. There is just 1 piece not working and that is JMX Bean Management. From the docs:
To interact with JMX-beans in the admin UI you have to include Jolokia
in your application. As Jolokia is servlet based there is no support
for reactive applications. In case you are using the
spring-boot-admin-starter-client it will be pulled in for you, if not
add Jolokia to your dependencies.
I understand it does not work with Reactive WebFlux but I am using Servlet Based example using Undertow as my servlet container. Configuration in pom.xml:
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-server</artifactId>
</dependency>
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-client</artifactId>

And as i stated everything is working except 1 thing and that is JMX control. I get the following error and I can't find any reason or logging as to why? Any help would be appreciated!
Start your program with following parameters:
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.port=1099
And (if using docker/kubernetes) expose port 1099
I have a project that uses Spring Boot 2.0.0.RC2. I need to deploy it to a customer environment using traditional deployment for Tomcat 7.0.82.
I've managed to build a war that can be deployed successfully by configuring web.xml in a typical way for Spring applications (with DispatcherServlet) instead of using SpringBootServletInitializer.
I also would like to have a quick way of starting the app on local environment using an embedded Tomcat container by simply running the main method in the application class with #SpringBootApplication annotation. It works fine if I'm using the default Tomcat version (8.5.28). However, I would like to start the embedded container also in 7.0.82 version. This is important for me for another reason - I'm using SpringBootTest and it would be nice if those tests run on the exact same container as the customer environment. Unfortunately, I can't use the Spring Boot parent POM and override tomcat.version property.
I've tried #SpringBootApplication(exclude = ServletWebServerFactoryAutoConfiguration.class) create TomcatServletWebServerFactory bean manually
#Bean
public ServletWebServerFactory tomcatServletWebServerFactory() {
return new TomcatServletWebServerFactory();
}
and add tomcat 7.0.82 dependencies explicitly in pom.xml (${tomcat.version} = 7.0.82):

but I'm still getting a java.lang.NoClassDefFoundError: org/apache/tomcat/util/scan/StandardJarScanFilter error.
Could you please advise if there is any way to meet my requirements?
