When I try to run my spring-boot project with hibernate and MySql, I got following error.

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

You have used the @Id annotation from a wrong package:

import org.springframework.data.annotation.Id;

It HAS to be:

 import javax.persistence.Id;

thanks for mentioning that issue. But I still getting the above error – Tenusha Guruge Jul 10 '19 at 10:16
can it be you need a getter too on id? public Long getId() – ValerioMC Jul 10 '19 at 10:35
Does it have this? No identifier specified for entity: com.sliit.af.model.Course – Maciej Kowalski Jul 10 '19 at 10:38
No, I have also added getters and setters for Id, But still getting the error mentiones in the question. – Tenusha Guruge Jul 10 '19 at 10:40
adding @Bean(name="entityManagerFactory") as the other answer, it solved the error but gives a different error.http://notepad.pw/stackoverflow-56968183 – Tenusha Guruge Jul 10 '19 at 10:41

Add @Id annotation in all your modal class (Course, Subject) Make sure package you import is import javax.persistence.Id;

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;
}

my previous answer

UPDATE import proper calss

import javax.persistence.Id;

you try to join subject class with course without foreign key reference... change your code according that image

Thanks for answer. I have added your code under `@Configuration`, it gives me an error. http://notepad.pw/stackoverflow-56968183 — Tenusha Guruge, Jul 10 '19 at 10:31

I was experiencing the same issue and I tried every answer listed in the posts. What I believe is the main issue is that I was lacking a spring-boot-starter-jdbc. Hence, my H2 database and table are being created but when spring attempts to autowire the beans that link the database the entityManagerFactory is unable to locate the beans. Why? Because their is no jdbc connection to begin a session. Therefore, most of us are missing spring-boot-starter-jdbc or if you have the dependency, then the dependency is listed after h2 database has already been created. — Daniel E Plummer, Sep 03 '20 at 19:19
After reviewing the code above, I believe the solution is to add spring-boot-starter-jdbc underneath spring-boot-starter-jpa. — Daniel E Plummer, Sep 03 '20 at 19:22
While this code may provide a solution to the question, it is better to add context on why / how it works. This can help future users learn and apply that knowledge to their own code. Please add this context in the answer, not in the comments. Thanks — borchvm, Sep 04 '20 at 05:24

I had the same issue, I fixed it by adding the version to javax persistence api like in pom.xml, changing this :

    <dependency>
        <groupId>javax.persistence</groupId>
        <artifactId>javax.persistence-api</artifactId>
    </dependency>

To this :

Adding @EntityScan(basePackages = "io.summer") to your Application class. That is needed for hibernate to scan your entities. (Worked for me, for postgresql)
