On adding #EnableWebSecurity to the configuration class app is not running

I have a spring-cloud-gateway to which I want to provide spring
security so I have added spring-boot-starter-security till here it
worked absolutely as expected!!
Now I would want to add customauthentication and authorization using JPA for this I have added
starter jpa and postgresql driver even it is worked fine.
The
problem is when adding #EnableWebSecurity annotation when I add this
to my security config class and run application is not running with
below exception stack
**Tried cleaning and updating project , created new app from scratch to resolve any cache issues nothing worked **
Any help would be appreciated!! Thanks in advance!! :)

AWS EC2 / MySql - spring boot Unable to determine jdbc url from datasource

I have a simple Spring Boot application that I'm trying to deploy on an Amazon EC2 instance based on the Amazon AMI. It uses a MySql database (version 8.0.15).
I've created the database on AWS, and when I point the configuration at it from my local system, it works. I'm also able to access it from MySql Workbench.
But when I upload the Spring Boot jar file to the EC2 instance and run it, it's unable to connect to the database, with the message "Unable to determine jdbc url from datasource":
2019-05-31 20:51:38.266 WARN 5150 --- [ main] o.s.b.a.orm.jpa.DatabaseLookup : Unable to determine jdbc url from datasource

EurekaServer created by STS not starting

I'm new to Spring cloud, going through some videos I have created EurekaServer from STS , and tried to run as spring-boot application.
Is anything from below which I need to do?
configure anything for making Euraka server run?
before running Euraka server, do I need some other services up and running?
add any properties in application.properties at resources folder?
My application.properties is empty as of now and I am getting the following error.
2018-07-10 01:31:11.109 INFO 13760 --- [ main]

Can any one please help identify what I'm missing?

configure anything for making Eureka server run?
No, if you just include eureka server dependency from STS starter project, that is all that is "required" to create sample starter.
before running Eureka server, do I need some other services up and running?
No, it is not necessary to have any service to be registering with eureka server.
add any properties in application.properties at resources folder?
This is little complicated. Theoretically, no, it is not required to add any properties, but due to inclusion of eureka-server dependency and #EnableEurekaServer, it will try to register with eureka server, which will throw a runtime exception, but not stop/teminate your application. To solve this you can add
eureka.client.fetch-registry=false
eureka.client.register-with-eureka=false
Beside this if you are running multiple spring boot application from your local machine, then it is advised to add
server.port=<your port like 8080, 8081 etc>
Coming to your exception you faced, I tried following exact steps as you suggested, but I didn't get any exception while starting the app.
So here is my guess on what could have caused
You had another application running on the same port at that time - i.e port 8080 (which is default port)
I have seen the exception in your trace for some cases where app is being configured to run in google cloud app engine, not sure if that's what was being tried.
I have created a sample vanilla eureka server project, hope it helps you
sample eureka server

You can try giving below code in yml file or use same properties. Other than this all looks good to me.
server:
port: {port_number}
spring:
profiles: default
application:
name: eureka-server.com
eureka:
instance:
hostname: eureka-server.com
appname: eureka-cluster
client:
register-with-eureka: false
fetch-registry: false
service-url:
defaultZone: http://${spring.application.name}:${server.port}/eureka/
logging:

Error when adding "spring-boot-starter-data-jpa" dependency to Spring project

I'm practising Spring with Spring Tool Suite. I've been trying to connect my project to database.
However, whenever I add "spring-boot-starter-data-jpa" dependency to pom.xml the project won't start and I get the following errors. The error doesn't occur once I remove the dependency. I have no idea why they are happening. Here are the following errors:
org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tomcatEmbeddedServletContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/web/EmbeddedServletContainerAutoConfiguration$EmbeddedTomcat.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'serverProperties' defined in class path resource [org/springframework/boot/autoconfigure/web/ServerPropertiesAutoConfiguration.class]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/HibernateException

I tried updating Maven and validating the project but the error persists.

Even I encountered the same error. The process i followed as below, let you try and check whether it works out..
Just remove the below lines from pom.xml
org.springframework.boot
spring-boot-starter-data-jpa
Just downloaded the JAR from the link below and added to the build path of your project.
http://www.java2s.com/Code/JarDownload/eclipselink/eclipselink-javax.persistence-2.0.jar.zip
Now run the maven build. Hopefully It should work out.

Creating a Spring Boot admin server that also contains Sleuth Dependencies

I am developing a Spring Boot Admin Server. When I add Sleuth dependencies (for tracing requests and responses in a distributed architecture), I am getting an exception on startup.
When I comment out the Sleuth dependencies in my POM, the application starts just fine.
