I am trying to send an event to a consumer. I am getting NullPointerException
Here is my event code
public class Activator implements BundleActivator {
EventAdmin eventAdmin;
#Override
public void start(BundleContext bundleContext) throws Exception {
System.out.println("started");
Dictionary<String, String> properties = new Hashtable<>();
properties.put("test", "blah");
Event event = new Event("test/sent", properties);
System.out.println("sending");
eventAdmin.sendEvent(event);
}
#Override
public void stop(BundleContext bundleContext) throws Exception {
System.out.println("stopped ");
}
}
Here is the LOG

You use the field eventAdmin that is never set. So you get a NullPointerException. I suggest to use declarative services instead and inject EventAdmin using #Reference.
See OSGi Event Admin – Publish & Subscribe from Vogella for all details.

this is websocket security config:
#Configuration
public class WSSecurityConfig extends AbstractSecurityWebSocketMessageBrokerConfigurer implements ApplicationContextAware {
#Override
protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) {
messages
.nullDestMatcher().denyAll()
.simpSubscribeDestMatchers("/topic/t01", "/topic/t99").authenticated()
.anyMessage().denyAll();
}
}
the context fails to load with this error (trimmed only to the relevant parts):

I looked at the culprit class AbstractSecurityWebSocketMessageBrokerConfigurer, the exception was thrown in method configureClientInboundChannel, the context is null. after some debugging I found out that the context was set before this method get called (of course with not null value) by setApplicationContext but the object (proxy) reference was not same when these two method was called (configureClientInboundChannel and setApplicationContext)
#Override
public final void configureClientInboundChannel(ChannelRegistration registration) {
ChannelSecurityInterceptor inboundChannelSecurity = context.getBean(ChannelSecurityInterceptor.class);
.

.
}
more information:
spring boot version: 2.3.1.RELEASE
spring security version: 5.3.3.RELEASE
I have a Spring Boot app that sends and receives messages on a GCP PubSub queue. Basically I try to store in the DB some of the information that I get in the message. However when I try to commit this information or saveAndFlush() I get the error RollbackException: Error while committing the transaction. If I persists any other information that it's not triggered when the app receives an inbound message it works correctly. If I try saveAndFlush instead of save I get a NullPointerException.
What am I missing?
Thanks.

Solved.
SecurityContextHolder.getContext().getAuthentication()
was null when the message is coming from the GCP PubSub. Reworking the getCurrentAuditor did the trick.
#Override
public Optional<String> getCurrentAuditor() {
if(SecurityContextHolder.getContext().getAuthentication()!=null){
SamlUserDetails userDetails = (SamlUserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
return Optional.of(userDetails.getFullname() + " (" + userDetails.getAttribute("uid") + ")");

Does anyone knows about this?
Topic user_event not present in metadata after 60000 ms.
Do you have the topic user_event?
If not you need to create it or else configure Kafka admin to create topic automatically.
I have installed Cassandra in my windows environment, I run it with cassandra.bat.
Now, I have an Spring Boot application that contains the following cassandra configuration file:
#Configuration
#EnableCassandraRepositories(
basePackages = "org.manuel.cassandra.repositories")
public class CassandraConfig extends AbstractCassandraConfiguration {
#Override
protected String getKeyspaceName() {
return "testKeySpace";
}
#Bean
public CassandraClusterFactoryBean cluster() {
CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
cluster.setContactPoints("127.0.0.1");
cluster.setPort(9142);
return cluster;
}
#Override
protected boolean getMetricsEnabled() { return false; }
#Bean
public CassandraMappingContext cassandraMapping() throws ClassNotFoundException {
return new CassandraMappingContext();
}
}
But I can't run the application because I get this:

These are my cassandra related dependencies:
implementation 'org.springframework.boot:spring-boot-starter-data-cassandra'
implementation 'com.datastax.cassandra:cassandra-driver-core:4.0.0'
implementation 'io.dropwizard.metrics:metrics-jmx:4.1.0'
My application.yml file is empty and I also have declared a repository, but I think the error isn't related to that problem.
The spring-boot-starter-data-cassandra depends on the sprint-data-cassandra that uses Java driver 3.6.0, and you have specified the dependency on the 4.0.0 - this version is not binary compatible with 3.x releases, so you need to correct your dependencies.
I updated my project to spring-boot Version 2.1.0.RELEASE.

Using the property introduced in this issue https://github.com/spring-projects/spring-boot/issues/14778 seems to have no effect to solve my issue.
How can i disable jmx for cassandra?
My current cassandra config looks like this:
#Configuration
#EnableReactiveCassandraRepositories({"repository"})
public class CassandraConfig extends AbstractReactiveCassandraConfiguration {
#Value("${cassandra.host}")
private String host;
#Override
protected String getKeyspaceName() {
return "keyspace";
}
#Override
public String[] getEntityBasePackages() {
return new String[]{"model"};
}
#Override
public SchemaAction getSchemaAction() {
return SchemaAction.CREATE_IF_NOT_EXISTS;
}
#Override
public String getContactPoints() {
return host;
}
}
The spring.data.cassandra.jmx-enabled property is used when Spring Boot is auto-configuring a Cassandra Cluster bean. By extending AbstractReactiveCassandraConfiguration, you are switching off this auto-configuration in favour of the Cluster bean that's created by AbstractClusterConfiguration which is a super-class of AbstractReactiveCassandraConfiguration. As a result, the property has no effect.
There are two ways that you can fix your problem:
Remove your AbstractReactiveCassandraConfiguration sub-class and use the various spring.data.cassandra.* properties to configure things instead.
Override cluster on AbstractClusterConfiguration in CassandraConfig, call super.cluster() to get the CassandraClusterFactoryBean and then call setJmxReportingEnabled(false) on the factory bean before returning it.
Alternatively, if you are not using Dropwizard elsewhere in your application, you may be able to downgrade to an older version that is compatible with Cassandra's JMX reporting by overriding the dropwizard-metrics.version property in your pom.xml or build.gradle.
instead of overriding cluster as mentionned by Andy Wilkinson, you could alternatively override getMetricsEnabled so that always returns false.
#Override
protected boolean getMetricsEnabled() { return false; }
I tried the the answers here, I don't know how but error still persisted.
I read this from docs.datastax.com , where they talked about Moving JMX reporting in Metrics 4 to a separate module, metrics-jmx. Which they made clear that it might cause issues/errors.
To fix this, I just had to call this method .withoutJMXReporting() as in the below.
Cluster cluster = Cluster.builder()
.withoutJMXReporting()
.build();
You can follow quietly here
Including old version of library also fixes problem:
implementation("io.dropwizard.metrics:metrics-core:3.2.2")
#Bean
public CassandraClusterFactoryBean cluster() {
CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
cluster.setContactPoints(environment.getProperty("spring.data.cassandra.contact-points"));
cluster.setPort(Integer.parseInt(environment.getProperty("spring.data.cassandra.port")));
cluster.setJmxReportingEnabled(false);
return cluster;
}
cluster.setJmxReportingEnabled(false) is the answer seems.
