I just Created this file from spring.initializer.
It is a brand new file. I am trying to run this because I have a previous project that have similar type of error. So I thought of making a new project and see if any error comes. below i the Error

I See this
java.lang.NoClassDefFoundError: org/hibernate/boot/model/naming/CamelCaseToUnderscoresNamingStrategy
Caused by: java.lang.ClassNotFoundException: org.hibernate.boot.model.naming.CamelCaseToUnderscoresNamingStrategy
Couple of solutions
Check if you have this class CamelCaseToUnderscoresNamingStrategy under your Maven dependencies -> org.hibernate dependency -> path boot/model/naming
If you can't locate that class, add a hibernate dependency with version >= 5.5.4
Check if this article helps Spring boot application and hibernate are using different naming strategies

I deleted the Hibernate folder from C:\Users{User}.m2\repository.
Then I added below dependency in the pom file.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.5.4.Final</version>
</dependency>
Also add version to maven plugin -:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
**<version>${project.parent.version}</version>**
</plugin>
Do the above steps if anyone gets the same Error.

Usually, invalid LOC header means your local maven repository got corrupted.
Go to ~/.m2/repository directory, find the hibernate directory, delete it, and rebuild the project.

Spring boot microservice Zuul is not running

I'm creating gateway using Zuul. I'm unable to start the Zuul application. Is spring boot 2.x is not supporting Zuul?
Instead of Zuul is it recommended to use Spring Cloud Gateway from 2.x onwards?

Check if the hystrix-coreXX.jar is corrupted in your .m2 folder. If not then try adding the exclusion for hystrix-core jar to eureka, zuul and add dependency for hystrix core like below.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
<exclusions>
<exclusion>
<groupId>com.netflix.hystrix</groupId>
<artifactId>hystrix-core</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-zuul</artifactId>
<exclusions>
<exclusion>
<groupId>com.netflix.hystrix</groupId>
<artifactId>hystrix-core</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.netflix.hystrix</groupId>
<artifactId>hystrix-core</artifactId>
<version>1.5.12</version>
</dependency>

By looking at the exception that you've got, looks like you are trying to use Netflix Hystrix without adding the necessary dependency on pom.xml. Either correct your code to not use Netflix Hystrix or add the necessary dependencies...
Can you please update your pom.xml to add the following as well?
<!-- https://mvnrepository.com/artifact/com.netflix.hystrix/hystrix-core -->
<dependency>
<groupId>com.netflix.hystrix</groupId>
<artifactId>hystrix-core</artifactId>
<version>1.5.12</version>
</dependency>
Hope this helps!

Try adding spring-cloud-starter-eureka as a dependency

Spring cloud netflix eureka server - tomcat error on startup

this is my first question at stackoverflow, so I try my best to describe everything in detail.
I have a simple spring-cloud-starter-netflix-eureka-server gradle based project which should only start the eureka server inside a docker container.
I am really new to spring. I tried some older versions of spring cloud starter but nothing worked.
I am building the jar on ubuntu 18.04 with openjdk 10.
It would be really nice if someone could help me!
Thanks a lot!
My SpringBootApplication class looks like this:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
#SpringBootApplication
#EnableEurekaServer
public class EurekaServiceRegistryApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServiceRegistryApplication.class, args);
}
}
Here is my build.gradle:
plugins {
id 'java'
id 'org.springframework.boot' version '2.0.3.RELEASE'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
compile group: 'org.springframework.cloud', name: 'spring-cloud-starter-netflix-eureka-server', version: '2.0.0.RELEASE'
}
And my dockerfile:
FROM openjdk:8-jre-alpine
ADD ./build/libs/eureka-service-registry-1.0-SNAPSHOT.jar /app/
CMD ["java", "-jar", "/app/eureka-service-registry-1.0-SNAPSHOT.jar"]
EXPOSE 8761
When I run my docker container (and also when I start the application from within IntelliJ) I get the following:

I've had the same problem.that spring-boot version must one-to-one match eureka version.you can reference to http://projects.spring.io/spring-cloud/
example:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.12.RELEASE</version>
<parent>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.SR5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

You need to select proper spring boot and spring cloud version. Also, i was getting error for jettison hence added dependency for jettison to resolve this.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.5.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

Thank you so much for your comments! I first added the spring-boot-starter-web, then the error changed to something with gson.
The answer from here solved my problem at the end.
