Spring Boot - “Error creating bean with name 'entityManagerFactory'” - Start

Spring Boot - “Error creating bean with name 'entityManagerFactory'” - Start - java

I have seen a lot of questions but the answers are not satisfying my problem...
I generate my project with Spring initialzr
I tried with the 3 java versions 14, 11, 8.
This is my project structure.
GardenApplication.java. I include all anottations even spring doc says that with #SpringBootApplication is enough. Before this error #Repository couldn't be found and I include #EnableJpaRepositories

spring.datasource.username=root
spring.datasource.password=admin
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.hibernate.ddl-auto=create

Please remove the exclusion of the auto configuration in your application.properties and add an hibernate-dialect, i.e. update your application.properties as follows:
spring.datasource.url=jdbc:mysql://localhost:3306/garden
spring.datasource.username=root
spring.datasource.password=admin
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.hibernate.ddl-auto=create
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
In addition you can simplify GardenApplication to
package com.garden.garden;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
#SpringBootApplication
#EnableJpaRepositories
#EntityScan
public class GardenApplication {
public static void main(String[] args) {
SpringApplication.run(GardenApplication.class, args);
}
}
and remove tomcat dependency from your pom (it comes in transitively with spring-boot-starter-web).
Besides, having lombok in your dependencies, you can annotate Vegetable with #Data and remove Getters, Setters and the constructor.

No operations defined in spec!! and 404 error in postman. The spring boot don't show any error from my code. yet i can't establish the connection

This is a simple code that i got from youtube for practice. well i did the code correcly but i cant get the explicit mapping correclty, that what the 404 error in the postman says.

The main problem here is the wrongly placed #SpringBootApplication. A Spring Boot application has a main start class which bootstraps the whole application. This class should get the mentioned annotation. It is a special annotation that also already includes component scanning.
By default, components are scanned only in the same package, where that annotation is found, and in its sub-packages. You have placed the annotation onto your class RunStat in the package com.qa.project.domain. Thus, all components in other packages - such as com.qa.project.service - are not found.
The solution:
Create a class with the name RunStatApplication (or similar) and place it into the package com.qa.project. That class gets the annotation #SpringBootApplication. With that setup, all other components are now in sub-packages and thus are found.

Ive tried everything I can think of, Any suggestions at all will be helpful.
Thanks!

By naming your method "findOne" the Spring Data JPA is trying to create a query to search by for the property "findOne" in your Product Class, which doesn't exist, hence the error "No property findOne found for type Product". You should specify the name of the property you are searching for. In your case: findOneById (String id) will create a query to find one object by the Id property.
For more information on how to name your methods to create the correct queries you can read the documentation about this topic.

Why don't you use CrudRepository instead of JpaRepository? findOne(id) will be automatically available. That way your repository interface whould just be empty.
https://docs.spring.io/spring-data/data-commons/docs/1.6.1.RELEASE/reference/html/repositories.html

spring boot data jpa mysql could not create database

I am new in spring
I will post my code,
that the application.properties
spring.datasource.url=jdbc:mysql://localhost/spring
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.hibernate.ddl-auto=update
and this my entity
package model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
#Entity
public class Person {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
private String name;
private String phone;
private String adresse;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getAdresse() {
return adresse;
}
public void setAdresse(String adresse) {
this.adresse = adresse;
}
public Person(long id, String name, String phone, String adresse) {
super();
this.id = id;
this.name = name;
this.phone = phone;
this.adresse = adresse;
}
public Person() {
super();
}
}
and this is the repository
package repositry;
import org.springframework.data.jpa.repository.JpaRepository;
import model.Person;
public interface PersonRespositry extends JpaRepository<Person, Long> {
}
and my controller
package contoller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import model.Person;
import repositry.PersonRespositry;
#RestController
public class PersonController {
PersonRespositry rp;
#Autowired
public PersonController(PersonRespositry rp) {
// TODO Auto-generated constructor stub
this.rp=rp;
}
#RequestMapping("/find")
public Person find(long id){
return rp.findOne(id);
}
#RequestMapping("/findall")
public List<Person> findall(){
return rp.findAll();
}
#RequestMapping(value="/hello")
public String Demo(){
return "Hello world !!";
}
#RequestMapping(value="/create", method=RequestMethod.GET)
public String create(){
Person p=new Person();
p.setName("med");
p.setPhone("233888");
p.setAdresse("rue ");
rp.save(p);
return " success";
}
}
This is the architect of the project:
When I run the application the database does not generate and only the
localhost:8080 is running.

Your problem is the location of the Application.java.
#ComponentScanlooks for Spring beans inside the package of the class annotated with (#SpringBootApplication contains #ComponentScan) and in subpackages of this package.
I already provided an example to a very similar setup.
Please have a look here: https://stackoverflow.com/a/27983870/2576531
Furthermore the hint of Robert Moskal is correct. The database itself has to exist already. Only the tables will be created automatically.

If you want the data to be created you need to use create or create-drop. If you are using something like mysql you'll need to have created at least the database. The tables will be created for you.
I be very careful about doing this against a production database instance.

Otherwise for me it dosen't work with #componentScan but it works now with #EntityScan(basePackages = { "com.jwt.entites" }) in the main class to scan entity classes ..

This is not the answer but this is a sample. I think this will help you

Getting the error : Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException

I am new to spring and I wanted to communicate with mongodb via spring. I tried and tested the following code on SPRING TOOL SUITE but I am getting the following error:
Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [hello.PersonRepository] is defined
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:371)

at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:968)
at hello.Runhere.main(Runhere.java:19)
Kindly tell me where is the problem.
Here is Person.java class
package hello;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
#Document
public class Person {
#Id
private String personId;

public void setAge(final int age) {
this.age = age;
}
#Override
public String toString() {
return "Person [id=" + personId + ", name=" + name + ", age=" + age
+ "]";
}
}
Here is my PersonRepository.java file
package hello;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Criteria;

Criteria criteria = new Criteria();
criteria = criteria.and("age").lte(21);
query.addCriteria(criteria);
results = mongoTemplate.find(query, Person.class);
System.out.println(results.size());
}
public void countAllPersons() {
List<Person> results = mongoTemplate.findAll(Person.class);
System.out.println("The total number of players " + results.size());
}
public void insertPersonWithNameAayushAndRandomAge() {
double age = Math.ceil(Math.random() * 100);
Person p = new Person("Aayush", (int) age);
mongoTemplate.insert(p);
}
public void createPersonCollection() {
if (!mongoTemplate.collectionExists(Person.class)) {
mongoTemplate.createCollection(Person.class);
}
}
public void dropPersonCollection() {
if (mongoTemplate.collectionExists(Person.class)) {
mongoTemplate.dropCollection(Person.class);
}
}
}
Here is my springconfig.java file:
package hello;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;

public class springconfig extends AbstractMongoConfiguration {
#Override
protected String getDatabaseName() {
return "demo";
}
#SuppressWarnings("deprecation")
#Override
public Mongo mongo() throws Exception {
return new Mongo();
}
}
Here is my class which contains the main method :
package hello;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
public class Runhere {
public static void main(String[] args) {
#SuppressWarnings("resource")
ApplicationContext context = new AnnotationConfigApplicationContext(springconfig.class);
PersonRepository personRepository = context.getBean(PersonRepository.class);
personRepository.dropPersonCollection();
personRepository.createPersonCollection();
for (int i = 0; i < 10000; i++) {
personRepository.insertPersonWithNameAayushAndRandomAge();
}
personRepository.countAllPersons();
personRepository.countUnderAge();
}
}

try to add bean in the application config.xml
<mvc:resources mapping="" location="" />
<bean id="PersonRepository" class="(complete package path)hello.PersonRepository" />

SpringBoot - In hope it will help any SpringBoot developer
This error mostly hits when the bean you are calling from another package.
Specifically for Spring boot, you can try an annotation for it, to scan the component you want to get bean of it.
#ComponentScan("your package")
place the #Componentscan annotation in the main class where you are getting the bean.
Example
#ComponentScan("com.spring.crud.controller")
public class SpringCrudApplication {
public static void main(String[] args) {
ApplicationContext context = SpringApplication.run(SpringCrudApplication.class, args);
HomeController bean1 = context.getBean(HomeController.class);
System.out.println(bean1.HomePage());
}
}
so, in the above example I am taking controller bean which I created in the package of com.spring.crud.controller
if you are interested in explanation see this article:
