springboot2.7.5 start error Caused by: java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder

I introduced the spring-boot-starter-web, used its own spring-boot-starter-logging framework, specified the configuration file in yaml, and reported startup errors

i have import slf4j 2.0.3 derect in the pom,but it doesn't work

SLF4J drastically changed the way its implementations are found between versions 1.x and 2.x. In 1.x, the binding class needed to provide a class named org.slf4j.impl.StaticLoggerBinder - the class that's missing. In 2.x it uses the ServiceLoader mechanism.
Spring Boot currently still uses SLF4J 1.7.36, through spring-boot-starter-web -> spring-boot-starter -> spring-boot-starter-logging. The latter depends on some SLF4J bridges, as well as logback-classic which in turn depends on SLF4J 1.7.32. I think that the 1.7.36 "wins" over the 1.7.32.
Unless one of your other dependencies has a transitive dependency on SLF4J 2.x, everything should work just fine. If you do, then you have a mix of SLF4J 1.x and 2.x, and that's simply not going to work. Replace the 2.x dependency with a 1.x dependency and you should be fine (unless you use the fluent API that was added in 2.x).

Zookeeper property still a requirement in the Kafka consumer?

I was referring to a post here:
Connecting to Zookeeper in a Apache Kafka Multi Node cluster
Its mentioned here that from kafka V9 version, Producer and Consumer does not have to use the zookeeper.connect property and just the bootstrap.servers is enough to producer/consume data.
My POM.xml looks like this in the consumer side:
<properties>
<java.version>1.7</java.version>
<kafka.version>0.9.0.1-cp1</kafka.version>
<kafka.scala.version>2.11</kafka.scala.version>
<confluent.version>2.0.1</confluent.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka_2.10</artifactId>
<version>0.10.0.0</version>
</dependency>
I run into the following issue in the consumer side, without zookeeper.connect property. Does anyone has the consumer part working without the zookeeper connect property ?

Only the new consumer works without connecting to Zookeeper and that is available in the kafka-clients artifact. You have to add the dependency:
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>
<version>0.10.0.0</version>
</dependency>
and use the implementation from the org.apache.kafka.clients.consumer. package.

Neo4j - Unmanaged extensions with SDN - InvalidDataAccessApiUsageException: Could not resolve dependency of type:javax.transaction.TransactionManager

I followed example from: https://inserpio.wordpress.com/2014/04/30/extending-the-neo4j-server-with-spring-data-neo4j/
Created 1 Repo, 1 Controller (with get and put rest endpoints. get /test/get/{name} uses 'name' property to get the node, put /test/create is just a test endpoint for now that always should create same node which later on i want to get...) and 1 Domain class.. Together with the PluginInitializer, that exposed Neo4jTemplate and my custom repo.
My app-context:
<context:annotation-config />
<context:spring-configured />
<context:component-scan base-package="uk.co.neo4j.extension.tvshow">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<neo4j:config base-package="uk.co.neo4j.extension.tvshow.domain" graphDatabaseService="graphDatabaseService" />
<neo4j:repositories base-package="uk.co.neo4j.extension.tvshow.repository" />

Followed by maven-compiler-plugin to copy all dependant jar files into lib folder. Add PluginInit fqp to PluginLifecycle file, as well as added package to neo4j server config:
org.neo4j.server.thirdparty_jaxrs_classes=uk.co.neo4j.extension.tvshow=/tv
I copied my jar file + all dependant jar files into neo4j server plugin folder, started it successfully:
**2015-03-22 21:49:37.411+0000 INFO [o.n.s.m.ThirdPartyJAXRSModule]: Mounted unmanaged extension [uk.co.neo4j.extension.tvshow] at [/tv]**

BUT! When I try to use it via rest, i.e. :PUT /tv/test/create OR :GET /tv/test/get/testnode i always get:
Error: 500 - Internal Server Error
In logs I found this, and it happens for both get and put:

...
So basically, whenever any operation is done against my repository:
testRepository.getTestNodeByName(name);
testRepository.save(testNode);
It treats it as transaction and the Transaction Manager is not found... From the doc's of SDN I've read that neo4jTransactionManager bean is already configured as part of Neo4jConfiguration, and yes I've checked - it is already there:
#Bean(name = {"neo4jTransactionManager","transactionManager"})
#Qualifier("neo4jTransactionManager")
public PlatformTransactionManager neo4jTransactionManager() throws Exception {
return new JtaTransactionManagerFactoryBean(getGraphDatabaseService()).getObject();
}
So what am I missing? :(
