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:
Caused by: java.lang.NoClassDefFoundError: com/datastax/driver/core/Session

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 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);

I saw this issue:
Springboot 2.6.0 / Spring fox 3 - Failed to start bean 'documentationPluginsBootstrapper'
Top answer say to put configuration property like that
spring.mvc.pathmatch.matching-strategy: ant-path-matcher And it's working perfectly, but not if you have Actuator dependency.
Is there a way to 'befriend' Spring Boot 2.6.x with Actuator with SpringFox 3.0.0?

I have same question, and get answers from springfox issue. Here's github issue!
Maybe you can try the following two ways first, which I saw from this issue and solved my problem.
you can try add spring.mvc.pathmatch.matching-strategy=ant-path-matcher in your application.properties, or application.yml.
add this bean to your app, note the need to add #Configuration on your config class
#Bean
public static BeanPostProcessor springfoxHandlerProviderBeanPostProcessor() {
return new BeanPostProcessor() {
#Override
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
if (bean instanceof WebMvcRequestHandlerProvider || bean instanceof WebFluxRequestHandlerProvider) {
customizeSpringfoxHandlerMappings(getHandlerMappings(bean));
}
return bean;
}
private <T extends RequestMappingInfoHandlerMapping> void customizeSpringfoxHandlerMappings(List<T> mappings) {
List<T> copy = mappings.stream()
.filter(mapping -> mapping.getPatternParser() == null)
.collect(Collectors.toList());
mappings.clear();
mappings.addAll(copy);
}
#SuppressWarnings("unchecked")
private List<RequestMappingInfoHandlerMapping> getHandlerMappings(Object bean) {
try {
Field field = ReflectionUtils.findField(bean.getClass(), "handlerMappings");
field.setAccessible(true);
return (List<RequestMappingInfoHandlerMapping>) field.get(bean);
} catch (IllegalArgumentException | IllegalAccessException e) {
throw new IllegalStateException(e);
}
}
};
}
It's true that actuator doesn't work with springfox 2022 spring boot 3.0.1 and
springfox 3.0.0, springfox is using ant_path_matcher which you should configure in the properties file as:
spring.mvc.pathmatch.matching-strategy=ant-path-matcher.
Otherwise when you have actuator in place, try adding the stated bean above, it worked for me. Thanks. Happy coding friends!
I am trying to send an event to a consumer. I am getting NullPointerException

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.

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.
I have a project which using Test Context Framework.
I'm execute the test using Run As -> JUnit Test but it show initializationError();

How to run the test ?
It looks like you might be running against an unsupported version of JUnit.
What version of spring-test are you using?
What version of junit are you using?
FYI: Spring 2.5 requires JUnit 4.4; Spring 3.0 and higher require JUnit 4.5 or higher.
