I want to start a new Spring Boot + Activiti project using the Spring Initializr, but the Activiti dependency does not show up on the dependencies
Try to add this dependency to you pom :
<dependency>
<groupId>org.activiti</groupId>
<artifactId>spring-boot-starter-basic</artifactId>
<version>${activiti.version}</version>
</dependency>

I am trying to create a spring boot application using spring cloud kafka stream which reads input from kafka cluster 1 and send it to kafka cluster 2 using single kafkastream application.
I am getting following exception during startup.
***************************
APPLICATION FAILED TO START
***************************
Description:
A component required a bean named 'sessionBrokers-KafkaStreamsBinderConfigurationProperties' that could not be found.
Action:
Consider defining a bean named 'sessionBrokers-KafkaStreamsBinderConfigurationProperties' in your configuration.
My configuration is as below
spring.cloud.function.definition=itemConsumedStream
#Input Configuration
spring.cloud.stream.bindings.itemConsumedStream-in-0.binder=sessionBrokers
spring.cloud.stream.bindings.itemConsumedStream-in-0.destination=${session.event.data.input.topic}
spring.cloud.stream.kafka.bindings.itemConsumedStream-in-0.consumer.configuration.key.deserializer=org.apache.kafka.common.serialization.StringSerializer
spring.cloud.stream.kafka.bindings.itemConsumedStream-in-0.consumer.configuration.value.deserializer=in.custom.JsonNodeDeserializer
#Output Configuration
spring.cloud.stream.bindings.itemConsumedStream-out-0.binder=searchBrokers
spring.cloud.stream.bindings.itemConsumedStream-out-0.destination=${itemConsumed.events.output.topic}
spring.cloud.stream.kafka.bindings.itemConsumedStream-out-0.producer.configuration.key.serializer=org.apache.kafka.common.serialization.StringSerializer
spring.cloud.stream.kafka.bindings.itemConsumedStream-out-0.producer.configuration.value.serializer=in.custom.JsonSerializer
#Input Binder Configurations
spring.cloud.stream.binders.sessionBrokers.type=kafka
spring.cloud.stream.binders.sessionBrokers.environment.spring.cloud.stream.kafka.streams.binder.brokers=${session.event.data.input.kafka.brokers}
#Output Binder Configurations
spring.cloud.stream.binders.searchBrokers.type=kafka
spring.cloud.stream.binders.searchBrokers.environment.spring.cloud.stream.kafka.binder.brokers=${search.kafka.brokers}
pom dependencies are
spring boot version
2.7.1
spring cloud version
2021.0.0
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-streams</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream-binder-kafka-streams</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream-binder-kafka</artifactId>
</dependency>
This is working if I use single binder ie
spring.cloud.stream.kafka.streams.binder.brokers=${session.event.data.input.kafka.brokers}
instead of multiple binders
I am writing service based on Spring webflux, which reads data from PostgreSQL using r2dbc. I need to use latest release of r2dbc, however I am getting NoSuchMethodError exception in using TransactionSynchronizationManager spring-tx 5.2.0.RELEASE library.
I basically need to know what is correct spring-tx library version to be compatible with version of spring-data-r2dbc which works correctly with latest r2dbc-postgresql and r2dbc-spi libraries.
Here are my Maven dependencies.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-r2dbc</artifactId>
<version>1.0.0.M2</version>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-postgresql</artifactId>
<version>0.8.0.RC2</version>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-spi</artifactId>
<version>0.8.0.M8</version>
</dependency>
I am using interface extending ReactiveCrudRepository interface to retrieve table data per below.
#Query("...")
Flux<QuoteHistory> findAllBySecIdAndDateTimeBetweenAndUpdateTypeIn(LocalDate date, Long secId);
I was able to get this code to work with earlier versions of r2dbc-postgresql and r2dbc-spi but now I am getting following exception.
java.lang.NoSuchMethodError: org.springframework.transaction.reactive.TransactionSynchronizationManager.currentTransaction()Lreactor/core/publisher/Mono;
at org.springframework.data.r2dbc.connectionfactory.ConnectionFactoryUtils.doGetConnection(ConnectionFactoryUtils.java:88) ~[spring-data-r2dbc-1.0.0.M2.jar:1.0.0.M2]

at org.springframework.data.r2dbc.core.DefaultDatabaseClient.getConnection(DefaultDatabaseClient.java:189) ~[spring-data-r2dbc-1.0.0.M2.jar:1.0.0.M2]
These are r2dbc dependencies which code works with.
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-r2dbc</artifactId>
<version>1.0.0.M1</version>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-postgresql</artifactId>
<version>1.0.0.M7</version>
</dependency>
Please use the following dependency combination:
R2DBC Postgres: 0.8.0.RC2
R2DBC SPI: 0.8.0.RC2
Spring Data R2DBC: 1.0.0.RC1
Spring Framework: 5.2.0.RELEASE
Alternatively, go to https://start.spring.io to get a dependency-managed project with versions that work together.
Anyone could englighten me which org.apache.camel version I should use with the Spring boot version 2.0.0 .RELEASE.
When I used newer versions of apache.camel such like 2.21.0 , I come across with RelaxedPropertyResolved error. I read the forums and I was told to downgrade the version of Spring Boot which I cant. I have to use sprint.boot.version 2.0.0 with a new apache.camel.version without making changes at my java code ?
Do you think is it possible?
These are my dependecies for camel.version and spring.boot.version. Please let me know if you need anything more.
<dependency>

Camel 2.21.x or older is Spring Boot 1.5.x
Camel 2.22.x is Spring Boot 2.0.x only
Camel 2.23.x is Spring Boot 2.1.x (and potentially also Spring Boot 2.0.x)
We are migrating from log4j to log4j2. We use the following libraries and there logging mechanisms:
Tomcat (which uses JULI), Spring 4.2.0 (which uses commons-logging) and Hibernate 4.3.11-Final (which uses jboss-logging).
I have successfully got Spring bridging to log4j2, but Hibernate logging is not working.
According to the Hibernate docs:
To use JBoss Logging with Log4j2, the log4j2 jar would also need to be available on the classpath.
I have the following logging-related jars on my classpath:
commons-logging-1.2.jar
jboss-logging-3.1.3.GA.jar
jboss-logging-annotations-1.2.0.Beta1.jar
log4j-api-2.6.1.jar
log4j-core-2.6.1.jar
log4j-jcl-2.6.1.jar
log4j-slf4j-impl-2.6.1.jar
slf4j-api-1.7.5.jar
slf4j-log4j12-1.7.5.jar
Any ideas why I'm not seeing the results I expect?
The version of jboss-logging included with hibernate-4 is not compatible with log4j2.
I had to import version 3.3.0.Final (should work starting with 3.1.4, according to JBLOGGING-94) for hibernate to work with log4j2.
Here is a shortcut if you use maven :
<dependency> <!-- version working with log4j2 -->
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
<version>3.3.0.Final</version>
<scope>runtime</scope>
</dependency>
I am using Spring + Jersey to build an API service .
Recently , I try to incorporate Spring Data to my server .
I haven't truly use any Repositories in my running code , just add one line in my app.xml :
<jpa:repositories base-package="destiny.web" entity-manager-factory-ref="entityManagerFactoryApp" />
But ! I notice my API not working , complaining "A message body writer for Java class xxx , and Java type class xxx , and MIME media type application/json was not found"
If I remove the "jpa:repositories ..." line in my xml , everything works fine !
and , all provider classes are registered by spring :
{http://*:8080-1} Registering Spring bean, apiResultJsonWriter, of type destiny.web.api.ApiResultJsonWriter as a provider class
{http://*:8080-1} Registering Spring bean, webApi, of type destiny.web.api.WebApi as a root resource class
{http://*:8080-1} Initiating Jersey application, version 'Jersey: 1.8 06/24/2011 12:17 PM'
But , if I add "jpa:repositories..." line in my XML , only "root resources class" are registered :
{http://*:8080-1} CDI support is enabled
{http://*:8080-1} Using default applicationContext
{http://*:8080-1} Registering Spring bean, webApi, of type destiny.web.api.WebApi as a root resource class
{http://*:8080-1} Initiating Jersey application, version 'Jersey: 1.8 06/24/2011 12:17 PM'
All JAXRS's #Provider(s) are missing !
I don't know if it is Spring-Data's bug ?
And how to solve it ?

spring-3.1

You need to register the packages that contain classes annotated with #Provider
in Jersey 2 this is done via by calling the packages method in your ResourceConfig class.
I believe there is also a basepackages attribue you can put on the servlet. See here Autodiscover JAX-RS resources with CXF in a Spring application
