java.lang.ClassNotFoundException: com.jdbc.mysql.Driver occuring even after adding java connector jar file [duplicate]

I was working with Spring Boot project, and suddenly I faced with an issue that application can not load MySQL jdbc.(I compiled this project once without changing anything) This is my pom.xml:

MySQL database is created with hibernate at first. These configurations worked fine but I am not sure what is the real problem here
EDIT : I removed .m2 folder and install all dependencies from beginning as well.

You need to add version to MySQL connector dependency and you need to change the
spring.datasource.driver-class-name
property.
MySQL changed the driver from
com.mysql.jdbc.Driver
to
com.mysql.cj.jdbc.Driver
You are missing the .cj. (This is for connector version above 5.* I think.
Hope this helps.
Cannot load driver class: com.mysql.jdbc.Driver
clearly states that Hibernate could not find the jdbc driver.

In addition to changing the driver class name as noted above
spring.datasource.driverClassName = com.mysql.cj.jdbc.Driver
I also had to modify my pom.xml from
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>provided</scope>
</dependency>
to
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.14</version>
</dependency>
to make sure the driver is present and have the message disappear.

This issue is resolved by changing your spring.datasource.driverClassName content and adding .cj into it, as Kristijan Rusu said.
spring.datasource.driverClassName = com.mysql.cj.jdbc.Driver

change mysql dependency version to 8.0.14..it works for me
and spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
in application.properties

This is issue resolved after the below property corrected.
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

I had same problem. Resolved it by changing in pom.xml

<version>2.0.2.RELEASE</version>

When I remove the dependency, the project runs successfully.
I'm just trying to add a Eureka client to register center but it doesn't work. When I create a new project with Spring Initializr though, it works well.
Every answer helps.

Try with version of spring boot : 2.2.2 as shown below
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
This class is available since 2.2.0.Please refer below link
https://docs.spring.io/spring-boot/docs/2.2.3.BUILD-SNAPSHOT/api/org/springframework/boot/context/properties/ConfigurationPropertiesBean.html

This is a common Spring Boot <-> Spring Cloud version compatibility mismatch problem. Have a look at the Table 1. Release train Spring Boot compatibility section at spring.io/projects/spring-cloud:
Spring Cloud <-> Spring Boot
2020.0.x (aka Ilford) <-> 2.4.x
Hoxton <-> 2.2.x, 2.3.x (Starting with SR5)
Greenwich <-> 2.1.x
Finchley <-> 2.0.x
Also see the complete list of all the spring-cloud-dependencies versions at Maven Central.
So in your case using Spring Boot 2.1.7.RELEASE, make sure to also use a Greenwich.SRx release (this is why Said Dekkaki`s answer works):
<properties>
<spring-cloud.version>Greenwich.SR6</spring-cloud.version>
</properties>
Or better: upgrade to a newer Spring Boot version (as Neeush Sreenivas suggested):
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.2.RELEASE</version>
</parent>
Or even better: Use both the most current versions - as of writing: spring-boot-starter-parent with 2.4.1 and spring-cloud-dependencies with 2020.0.0.

change your Spring Cloud version from Hoxton.RC1 to Greenwich.SR1 in your XML

Error creating bean with name 'entityManagerFactory' defined

on my spring application I have these problems.
Can anyone help me?
I add some things on the pom.xml but the application does not start and there are a lot of errors
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Thank you for the input, #Ken Chan!
Looking at your original pom, #Anita, there is one significant version conflict:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>4.2.2.RELEASE</version><!--$NO-MVN-MAN-VER$-->
</dependency>
doesn't match your spring-boot version! I assume it the cause of the problem...
If you are free to choose your spring version, then you should:
<dependency><!-- or completely omit this dep. -->
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
</dependency>
..use the version "managed" by "spring-boot-starter-parent". (Alternatively: not to declare it as (direct) dependency at all, but use the "transient one" from "spring-data-jpa")
..If you are restricted to Spring 4.2.2.RELEASE, then there is no "perfect match" of a spring-boot version, but best match would be: spring-boot-starter-parent/1.3.0.RELEASE, it bases on spring 4.2.3.RELEASE.

Caused by: java.lang.NoSuchFieldError: HANA

Since spring-boot-autoconfigure 2.1.1 , it add support for automatically detect DatabaseDriver.HANA. DatabaseDriver.HANA is from spring-boot.jar which is only added since 2.1.0.
So I believe your spring boot libraries are messed up somehow. You are using a spring-boot-X.Y.Z-RELEASE.jar which the version is less than 2.1.0 . You have to upgrade it to version 2.1.2 which match spring-boot-autoconfigure-2.1.2.RELEASE.jar that you are using

Spring 4.0 and ActiveMQ enableStompBrokerRelay error

I've successfully got the example running from here using a SimpleBroker.
My config is set up like:
#Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic");
//registry.enableStompBrokerRelay("/queue/","/topic/").setRelayHost("localhost").setRelayPort(61614);
registry.setApplicationDestinationPrefixes("/app");
}
When I comment out the SimpleBroker and try to use the StompBroker I get the following error.
ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'stompBrokerRelayMessageHandler' defined in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfigurat ion.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.messaging.simp.broker.AbstractBrokerMessageHandler org.springframework.messaging.simp.config.AbstractMessageBrokerConfiguration.stompBrokerRelayMessageHandler()] threw exception; nested exception is java.lang.NoClassDefFoundError: reactor/tcp/encoding/Codec

Am I missing some resource so that it won't create the bean stompBrokerRelayMessageHandler?
Running this on Tomcat v7.0 inside of STS and using ActiveMQ for the message broker.

You need add this at pom.xml
<!-- Reactor -->
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>1.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-tcp</artifactId>
<version>1.0.0.RELEASE</version>
</dependency>

To get Reactor 2.0 working with my Spring 4.2+ environment, I've added the following dependencies:
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>2.0.5.RELEASE</version>
</dependency>
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-net</artifactId>
<version>2.0.5.RELEASE</version>
</dependency>
<dependency>
<groupId>io.projectreactor.spring</groupId>
<artifactId>reactor-spring-context</artifactId>
<version>2.0.5.RELEASE</version>
</dependency>
See https://spring.io/blog/2015/02/18/reactor-2-0-0-rc1-with-native-reactive-streams-support-now-available
Then netty was missing in my classpath, so I've added:
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>
<version>4.0.31.Final</version>
</dependency>

Your stack trace indicates very clearly it is missing a class:
java.lang.NoClassDefFoundError: reactor/tcp/encoding/Codec
See How to read and understand the java stack trace? if you're not sure how to read it.
For any class not found problem, the most common solution is to include the corresponding jar into your classpath.
The simplest way to do this is go to http://search.maven.org and query the full class name that's missing, for example:
fc:reactor.tcp.encoding.Codec
This will tell you the class belong to reactor-tcp jar. You can either download the jar and manually add it to your classpath or simply paste the maven dependency xml to your pom file.

rsaez's answer is almost right, in my case at last.
I had to add this:
<!-- Reactor -->
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>1.1.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-net</artifactId>
<version>1.1.6.RELEASE</version>
</dependency>

I ran into the same issue and this worked for me. I am using Spring 4.1.6
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>1.1.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-net</artifactId>
<version>1.1.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-tcp</artifactId>
<version>1.0.1.RELEASE</version>
</dependency>

i have made it by following Alex Bretet above,
yet only one change is the version
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>2.0.8.RELEASE</version>
</dependency>
instead of 2.0.5
my app works on spring 4.3.18

If you are using spring boot you can just use the amqp and reactor-netty starters:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-reactor-netty</artifactId>
</dependency>
