Spring-boot: required a bean named 'entityManagerFactory' that could not be found

I am developing a Spring Boot application using JPA and encountering this error. I am not certain if I am using the correct annotations or missing dependencies. Any help would be greatly appreciated.

This is the error message

Try checking version of H2 along with JPA. In my case there was issue with this version only.

I found the problem in my import the thing is that framework.data.annotation.id was the problem when I changed it with import javax.persistence.Id. It solved it (I am using 2.7 spring boot with java 11 ). I hope i could fix your problem.

You either need to remove exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class} (and let Spring automatically configure your datasource) or configure your datasource manually

@Bean
@ConfigurationProperties(prefix="spring.datasource")
public DataSource dataSource() {
    return new YourCustomDataSource();
}

UPDATE: Seems like you have some mistakes in your properties:

spring.datasource.url== jdbc:mysql://localhost:3306/giflib
spring.db.driver= com.mysql.jdbc.Driver

Try to remove the extra = from the first line and use spring.datasource.driver-class-name property name for the second:

spring.datasource.url=jdbc:mysql://localhost:3306/giflib
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

Also add a version to your MySQL dependency:

compile "mysql:mysql-connector-java:6.0.6"

I think that because of these mistakes Spring is unable to autodetect your datasource type correctly.

For me, I'm wrting Spring Unit Test, in the Cotroller I declare repository variable, I move the repository and its behavior to another new class, and called the new class method in Controller.

Besides, for the Application class in src\main which is same package with src\test, keep the Application simple like:

package yourpackage;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ApplicationTest {

    public static void main(String[] args) {
        SpringApplication.run(ApplicationTest.class, args);
    }

}

then the problem is solved.

I was 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;
}

in our case was working fine but not for tests with @WebMvcTest

Took a while to find out but issue was:

@SpringBootApplication
@ComponentScan({"com.givenproject"})
@EntityScan("com.givenproject")
@EnableJpaRepositories("com.givenproject")
@Configuration
public class Application {

instead do:

@SpringBootApplication
@Configuration
public class Application {

and

@Configuration
@ComponentScan({"com.givenproject"})
@EntityScan(basePackages = "com.givenproject")
@EnableJpaRepositories(basePackages = "com.givenproject")
public class DataConfig {
}

I was getting the issue , because I forgot to remove the annotation @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class }) that I had added, while testing hardcoded values. Resolved the issue by simply using @SpringBootApplication

For me, I've forgotten to remove DataSourceAutoConfiguration.class from exclusions.

So this:

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
// Main class definition

Should be:

@SpringBootApplication()
// Main class definition

In my case the problem was exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class} declared in @SpringBootApplication annotation, so thanks to Kirill Simonov tip I solved the problem that spent all day long of searching and broking head. Removing it worked extremely fine for me after hours trying. Everything else was ok, @Service, @Autowired, @EnableAutoConfiguration and @ComponentScan are redundant in this spring boot version, so really much time trying tips in the internet.

I'm using spring boot 2.1.11.RELEASE version.

Programming is something funny, once I used the exclude solution to solve an error message, then the same thing was the problem now. So there's no magic spell or formula as this universe has lots and lots of different scenarios, even if it's similar to a previous one we worked on.

I tried several ways besides of mentioned suggestions to remove this error.I got resolved this error by just removing following code from application.properties

spring.jpa.properties.hibernate.cache.use_second_level_cache=true                                                   
spring.jpa.properties.hibernate.cache.use_query_cache=false                                                         
spring.jpa.properties.hibernate.generate_statistics=false

Run into same issue when trying to connect spring boot to mysql database.

What saved me was adding correct version of hibernate-core to my pom file. From hibernate onwards 5.2.0. hibernate-entitymanager is no longer needed. Hibernate-core 5.2.0 have problem with Spring Data JPA while process collection.Hibernate-core 5.2.1 and above is ok with Spring Data JPA if you are using Spring Data JPA. 

<dependency>
 <groupId>org.hibernate</groupId>
 <artifactId>hibernate-core</artifactId>
 <version> 5.2.1.Final</version>
</dependency>

You have chosen to bypass auto creation of EntityManagerFactory. Therefore you should add folowing two beans in one of your configuration classes, possibly in Application class.

private static String PROP_DB_DRIVER_CLASS = "spring.db.driver";
private static String PROP_DB_URL = "spring.datasource.url";
private static String PROP_DB_USER = "spring.datasource.username";
private static String PROP_DB_PASS = "spring.datasource.password";

@Autowired
private Environment env;

@Bean
public DataSource dataSource(){
      DriverManagerDataSource dataSource = new DriverManagerDataSource();
      dataSource.setDriverClassName(env.getProperty(PROP_DB_DRIVER_CLASS));
      dataSource.setUrl(env.getProperty(PROP_DB_URL));
      dataSource.setUsername(env.getProperty(PROP_DB_USER));
      dataSource.setPassword(env.getProperty(PROP_DB_PASS));
      return dataSource;
}

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
      LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
      em.setDataSource(dataSource());
      em.setPackagesToScan("com.sweng.giflib.model");

      JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
      em.setJpaVendorAdapter(vendorAdapter);
      em.setJpaProperties(additionalProperties());

      return em;
}

Don't forget to add the hibernate dependency to your project.
