You have a version mismatch. When you search on Maven for that class, you'll find that the package of the DocumentationProvider has changed from version 3.0.x to 3.1.x
org/apache/cxf/jaxrs/model/doc/DocumentationProvider
to
org/apache/cxf/jaxrs/model/wadl/DocumentationProvider
It's hard to tell where the mismatch is located without having insight into your entire build and package dependencies. But you may want to run
mvn dependency:tree -Dverbose
in your project folder to see which package versions come into question for raising your ClassNotFoundException.
use below dependency in your maven project to solve your issue,
<!-- https://mvnrepository.com/artifact/org.apache.cxf/cxf-rt-rs-json-basic -->
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-rs-json-basic</artifactId>

I am facing some errors in a spring boot project where I am using spring integration to connect to RabbitMQ. I am doing the configuration for RabbitMQ in XML files like this:
<!-- RabbitMQ configuration -->
<rabbit:connection-factory
id="rabbitConnectionFactory_2"
host="${queuing.events.host}"
port="${queuing.events.port}"
username="${queuing.events.username}"
password="${queuing.events.password}"
virtual-host="${queuing.events.virtual-host}"
publisher-returns="true"/>
<rabbit:template id="amqpTemplate_2" connection-factory="rabbitConnectionFactory_2" />
<rabbit:admin id="rabbitAdmin_2" connection-factory="rabbitConnectionFactory_2"/>
<rabbit:listener-container connection-factory="rabbitConnectionFactory_2" auto-startup="true" requeue-rejected="false" />
<bean id="rabbitListenerContainerFactory_2" class="org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory">
<property name="connectionFactory" ref="rabbitConnectionFactory_2"/>
</bean>
<!-- -->
But I am creating two of each component. How to set the primaries ones?
Now the problem comes here, I was using this version for spring cloud:
<spring-cloud.version>Dalston.SR2</spring-cloud.version>
And everything was working fine, but if I update the version to:
<spring-cloud.version>Edgware.RELEASE</spring-cloud.version>
This error is coming:
Description:
Parameter 0 of method rabbitSender in org.springframework.cloud.sleuth.zipkin2.sender.ZipkinRabbitSenderConfiguration required a single bean, but 2 were found:
- rabbitConnectionFactory: defined in null
- rabbitConnectionFactory_2: defined in null
Action:
Consider marking one of the beans as #Primary, updating the consumer to accept multiple beans, or using #Qualifier to identify the bean that should be consumed
And the error comes because of this dependency:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-sleuth-zipkin</artifactId>
</dependency>
If I remove this dependency the error is not coming.
You can find an example project to reproduce this scenario. In the pom file you'll see this:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.9.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
<spring-cloud.version>Dalston.SR2</spring-cloud.version> <!-- it works with this version-->
<!-- <spring-cloud.version>Edgware.RELEASE</spring-cloud.version> --> <!-- doesn't work with this version-->
</properties>
<dependencies>
<!-- SPRING BOOT -->
<!-- it fails because of this dependency in that we are using Edgware.RELEASE version -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-sleuth-zipkin</artifactId>
</dependency>
...
https://github.com/fjmpaez911/spring-integration-zipkin-cloud
So I need to know how to set a primary configuration for RabbitMQ and in addition I think that could be an issue because this error only comes if I use this version Edgware.RELEASE
Am I missing something?
fran, in Edgware.RELEASE the <artifactId>spring-cloud-sleuth-zipkin</artifactId> will resolve Zipkin 2 dependencies try using <artifactId> spring-cloud-starter-zipkin-legacy</artifactId> instead
To define the primary connection factory for RabbitMQ in XML files, you can do something like this:
<!-- Here the primary connection -->
<bean id="rabbitConnectionFactory" primary="true" class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">
<constructor-arg value="${spring.rabbitmq.host}"/>
<property name="username" value="${spring.rabbitmq.username}"/>
<property name="password" value="${spring.rabbitmq.password}"/>
<property name="virtualHost" value="${spring.rabbitmq.virtual-host}"/>
</bean>
<!-- RabbitMQ configuration -->
<rabbit:connection-factory
id="rabbitConnectionFactory_2"
host="${queuing.events.host}"
port="${queuing.events.port}"
username="${queuing.events.username}"
password="${queuing.events.password}"
virtual-host="${queuing.events.virtual-host}"
publisher-returns="true"/>
<rabbit:template id="amqpTemplate_2" connection-factory="rabbitConnectionFactory_2" />
<rabbit:admin id="rabbitAdmin_2" connection-factory="rabbitConnectionFactory_2"/>
<rabbit:listener-container connection-factory="rabbitConnectionFactory_2" auto-startup="true" requeue-rejected="false" />
<bean id="rabbitListenerContainerFactory_2" class="org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory">
<property name="connectionFactory" ref="rabbitConnectionFactory_2"/>
</bean>
I am trying to build a simple Spring MVC Web App with the functionality of file uploading.I got following error:
java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileItemFactory
After a quick search,all answers pointed to the missing of dependencies,but it seems not to be true in my case:
I have included the following code in pom.xml:
<dependencies>
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.1</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
</dependencies>
with commons.io-2.4.jar and commons.fileupload-1.3.1.jar added into lib folder.
One interesting thing I found was that whenever I deleted the code:
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize">
<value>10000000</value>
</property>
<property name="maxInMemorySize">
<value>10000000</value>
</property>
</bean>
the web app works fine(of course I removed the form for file uploading as well. )
If you visit the Maven Central Repository and enter the search term:
fc:org.apache.commons.fileupload.FileItemFactory
then every released artifact available containing that class will be listed.
You will find commons-upload 1.3.1 in that list.
Therefore you need to double check your deployment to ensure that jar is present.
Tip: Use fc: to locate jars in Maven Central that contain a specific class.
try to update your jar version, for Example:
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>2.0.0-SNAPSHOT</version>
</dependency>
We cann't find versions upper 1.3 on Apache and mvnrepository.com , but you can try this : https://repository.jboss.org/commons-fileupload/commons-fileupload/2.0.0-SNAPSHOT/
In fact, I encountered the same problem and now working fine with version 2.0 under SpringMVC framework.
I am getting the following error in the servlet-context.xml. I am following the following tutorial to get this done.
Multiple annotations found at this line:
- Class 'org.springframework.http.converter.json.MappingJackson2HttpMessageConverter'
not found
- Class 'org.springframework.http.converter.json.MappingJackson2HttpMessageConverter'
not found [config set: myapp/web- context]
<!-- Configure bean to convert JSON to POJO and vice versa -->
<beans:bean id="jsonMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
</beans:bean>
you have to add spring-web.jar in your classpath or if you are using maven then you should add the following dependency:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>X.Y.Z.RELEASE</version>
</dependency>
I have a spring project in which i am using a validator like the following:
<beans:bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"
p:basenames="WEB-INF/i18n/messages,WEB-INF/i18n/application"
p:fallbackToSystemLocale="false" />
<beans:bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
<beans:property name="validationMessageSource" ref="messageSource" />
</beans:bean>
<annotation-driven validator="validator" />
<resources location="/, classpath:/META-INF/web-resources/" mapping="/resources/**" />
When i run the project i get the following BeanCreationException:
org.springframework.beans.factory.BeanCreationException: Error creating bean with
name 'validator' defined in ServletContext resource [/WEB-INF/spring/appServlet
/servlet-context.xml]: Error setting property values; nested exception is

Here is my snippet of POM:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.3.2.RELEASE</version>
</dependency>
<!-- Hibernate entity manager with JPA 2 support. -->

<!-- The JSR-303 Bean Validation API library. -->
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.0.0.GA</version>
</dependency>
Why i am getting this error?
Thanks
Your dependencies are OK. Based on the provided information the error should not appear.
So I suggest you to check your IDE and whether the hibernate-validator dependency is really on classpath. If you are using Eclipse with M2E, try to update your project:
Project (right click on project) > Maven > Update Project....
This might be a broken backwards compatibility issue: https://jira.springsource.org/browse/SPR-10466
I had a similar problem using hibernate 5.2.10.Final and hibernate-validator 6.0.2.Final (that package version doesn't seem to be in sync with the others). Turns out, hibernate-validator's groupId was changed from org.hibernate to org.hibernate.validator. Once I made that change, the error went away, however I am using Dropwizard and noticed that there may be a version conflict somewhere, so that's something to keep an eye on.
I also had this exact same problem, tried all sorts of combinations of JAR versions, different bean definitions, even customised class implementations. Turns out, I just had to clean the project and restart Eclipse. Problem solved, and lesson learnt!
Check your dependency
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.2.8.Final</version>
</dependency>
Is must be at the same version of your other Hibernate dependencies.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
Just use following dependency, it will fix your issue as this dependency provides basic validation from get go similar to hibernate.
I'm getting my feet wet with Spring. I downloaded STS and I'm following basic examples from Spring in Action Second Edition. I'm stuck when trying to implement basic AOP and I guess I'm just missing some specific libraries in my project.
I say so because annotations like #Aspect are not recognized in my classes like also <aop:config> in my xml.
This are my Maven Dependencies:
junit-4.7.jar
spring-test-3.0.2.RELEASE.jar
spring-context-3.0.2.RELEASE.jar
spring-aop-3.0.2.RELEASE.jar
aopalliance-1.0.jar
spring-beans-3.0.2.RELEASE.jar
spring-core-3.0.2.RELEASE.jar
commons-logging-1.1.1.jar
spring-expression-3.0.2.RELEASE.jar
spring-asm-3.0.2.RELEASE.jar
log4j-1.2.14.jar
Please let me know what libraries I'm missing and where to find them.
Thank you!
EDIT:
The following:
<bean id="performancePointcut"
class="org.springframework.aop.aspectj.AspectJExpressionPointcut" >
<property name="expression" value="execution(* Performer+.perform(..))" />
</bean>
throws the following exception:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'performancePointcut' defined in file [C:\Users\Prova\Documents\STS\SpringIdol3\src\main\resources\META-INF\spring\spring-idol.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException
DONE!
This aspectj-annotation-tutorial did the job with steps 1, 2, and 3.
It's been a fun Friday night....
Put these two dependencies in your pom.xml:
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.6.11</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.6.11</version>
</dependency>
you may add maven dependencies:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>4.2.4.RELEASE</version>
</dependency>
