Error Creating Bean with Name 'Entitymanagerfactory' Defined in Class Path Resource:Invocation of Init Method Failed

Error creating bean with name 'entityManagerFactory' defined in class path resource : Invocation of init method failed

I would start by adding the following dependency:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>4.1.4.Final</version>
</dependency>

and

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>5.2.3.Final</version>
</dependency>

UPDATE: Or simply add the following dependency.

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

Error creating bean with name 'entityManagerFactory' defined in class path resource (Invocation of init method failed)

some day ago i am getting error message like required a bean named 'entityManagerFactory' that could not be found.

After lot of googling solve this problem. I set manual configuration for JPA.

@Bean 
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); 

    return sessionFactory;
}

but JPA by default search sessionFactory by name 'entityManagerFactory' so change my code as:

@Bean(name="entityManagerFactory")
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

    return sessionFactory;
}

import proper calss

import javax.persistence.Id;

Spring boot Error creating bean with name 'entityManagerFactory' defined in class path resource

Your comment:

**Here I'm trying to do a "spring-boot:run" and want to generate columns for all above 
five variables. But I'm getting this error :**

indicates that you want to have columns with the ids of the products and variants in your shopping table, however what you probably want to do is have a join table.

The error is telling you that your mapping is not understood, your use case should use a many to many relationship, and you will need a separate table to hold the foreign keys. Basically annotate the products and variants attributes with @ManyToMany and specify the join table, this is left as an exercise to you.

Check https://www.baeldung.com/jpa-many-to-many for an example

Error creating bean with name 'entityManagerFactory' defined in class path resource.No identifier specified for entity:

I had the same problem.
In my case,its because of wrong @Id annotation import.
It should be :- import javax.persistence.Id;
