Question

When I compile my spring project, I got the following error.

Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: 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>

@georges-van I've encountered the same error, and the 2 dependencies which you have mentioned are already present in spring-boot-starter-data-jpa I get the following error. anotepad.com/notes/wpjr5g

Just use the same versions which mentioned in post.

@georges, thevikasdube is already using spring-boot-starter-data-jpa dependency that includes Hibernate. Any reason he should be including hibernate dependencies explicitly ??

FYI hibernate-entitymanager is now deprecated. Use (only) hibernate-core instead.

For those interested in why versions post Java 8 require this explicit inclusion, there is an interesting article here; baeldung.com/java-9-jaxbexception , basically its related to Java 9s introduction of the modular system and an attempt to slim down all the libs that aren't essential...

Adding dependencies didn't fix the issue at my end.

The issue was happening at my end because of "additional" fields that are part of the "@Entity" class and don't exist in the database.

I removed the additional fields from the @Entity class and it worked.

Goodluck.

Wat do yu mean by additional fields?? Could you give more info on this.? i have same issue now

JAD Over a year ago

I meant additional properties that do not exist in the database, such as private / public integers..etc

Bandham Manikanta Over a year ago

Worked.! In my Entity class, there were two constructors (arg, no-arg)., i removed those and it worked. Thanks @JAD. happy coding.

z atef Over a year ago

Yes, this issue can be related to an issue in any of the entity classes.

Peter Over a year ago

Worked! The error was not dependency or entity manager configuration problem. The problem was the one of my entity class. After I created my entity classes with help of persistence manager the problem is been solved. Thanks.

I suspect that the jar files of hibernate-core and hibernate-entitymanager dependencies are corrupted or were not installed properly on your machine.

I suggest that you just delete the folders named hibernate-core and hibernate-entitymanager from your Maven local repository and Maven will reinstall them.

The default location for Maven local repository is C:\Documents and Settings\[USERNAME]\.m2 in windows or ~/.m2 in Linux/Mac.

It worked for me, I had updated the spring boot version from 1.5 to 2.3 and was getting this error.

I deleted my full repository and it works. It resolved this and a lot of other errors with spring boot

z atef · Accepted Answer · 2019-03-28 01:17:27Z

In my case, deleting any of the below annotations cause the error message 'entityManagerFactory' to show, for example.

 @Id
  @GeneratedValue(strategy=GenerationType.AUTO)

or

@ManyToMany(targetEntity=listOfObject_x.class)

The error message disappears after adding the missing annotation(s).

package mypackage_unameit;
import javax.persistence.PrePersist;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

import lombok.Data;

@Data
@Entity
public class Someclasss {

  @Id
  @GeneratedValue(strategy=GenerationType.AUTO)
  private Long id;

  @NotNull
  @Size(min=5, message="Name must be at least 5 characters long")
  private String name;

  private Date createdAt;

  @ManyToMany(targetEntity=listOfObject_x.class)
  @Size(min=1, message="You must choose at least 1 ingredient")
  private List<listOfObject_x>   = new ArrayList<>();

  @PrePersist
  void createdAt() {
    this.createdAt = new Date();
  }
}

I solved mine by updating spring dependencies versions from 2.0.4 to 2.1.6

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.4.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
</parent>

to

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->

For those who are not using JPA and instead prefer to exclude the entityManagerFactory and use Spring Data JDBC or Spring JDBC can exclude the bean to avoid the exception

@SpringBootApplication(exclude = {HibernateJpaAutoConfiguration.class})

indeed, when JPA is used, excluding this bean results in application failing to start with the following message : A component required a bean of type 'javax.persistence.EntityManagerFactory' that could not be found.

You can try to change the MySql Dialect.

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect

Or

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL8Dialect

pom dependency:

    <dependency>
        <groupId>com.mysql</groupId>
        <artifactId>mysql-connector-j</artifactId>
    </dependency>

For those who use Gradle instead of Maven, add this to the dependencies in your build file:

compile('javax.xml.bind:jaxb-api:2.3.0')

This error may be also related to the fact that you have an error in your "spring.datasource.url" when you gave a wrong db name for example

For my case it was due to Intellij IDEA by default set Java 11 as default project SDK, but project was implemented in Java 8. I've changed "Project SDK" in File -> Project Structure -> Project (in Project Settings)

This was also my problem, when you try to open an old project that uses Java8 with new downloaded IntellijIDEA this is the solution.

The issue was happening at my end because database myapplication in spring.datasource.url=jdbc:mysql://localhost:3306/myapplication didn't exist in mysql.

I created the db manually, restarted the application and it worked.

I was able to fix the problem by changing the maximum-pool size value from one to two

spring.datasource.hikari.maximum-pool-size=2

When we map a column, we have to pay attention to the name of the opposite column that is being mapped, for example:

/*users*/
@OneToMany(mappedBy = "partModel")
private List<UsersModel> usersModels;


/*parts*/
@ManyToOne
private PartModel partModel;

Check out postModel here.***

Try to annotate the class with @EnableTransactionManagement. I was facing the same issue and it got resolved by adding this.

@EnableTransactionManagement
public class ConfigurationBean {
}

If you use JDK 1.8.0_201 or latest try it with older JDK.

I have same issue with JDK1.8.0_201, however it works with JDK1.8.0_101 without any code change.

I resolved this issue by Adding implements Serializable in the Model.

@Entity
@Table(name="Model_Rest")
@IdClass(Model_Rest.class)
public class Model_Rest implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    /**
     * 
     */
    //@GeneratedValue(strategy = GenerationType.AUTO)
    //@Column(columnDefinition="id")

    @Id
    private String login;
    @Id
    private String password;




    @Autowired
    public String getLogin() {
        return login;
    }

    @Autowired
    public void setLogin(String login) {
        this.login = login;
    }

    @Autowired
    public String getPassword() {
        return password;
    }

    @Autowired
    public void setPassword(String password) {
        this.password = password;
    }

    public Model_Rest() {
        // TODO Auto-generated constructor stub
    }

    public Model_Rest(String login, String password) {
        this.login = login;
        this.password = password;
    }

    @Override
    public String toString() {
        return "Model_Rest [login=" + login + ", password=" + password + "]";
    }
  }

For me, it was a result of another error

org.postgresql.util.PSQLException: FATAL: password authentication failed for user

Which means you just need to review your authentication credentials

I had the same issue on my Eclipse Luna. I figure out that I am using JDK12 and Java 1.8. I changed JDK to JDK8 and the problem was solved. If you want to check your JDK in Eclipse go to

Window-> Preferences-> Java- >Installed JREs

and check if they are compatible with your project. Good luck!

For me it was the name of the database on application.properties. When I provided the correct name it worked ok.

Whoever still having the same issue. Please add the following line in application.properties

# The SQL dialect makes Hibernate generate better SQL for the chosen database
## I am using Mysql8 so I have declared MySQL8Dialect if you have other versions just add ## that version number
spring.jpa.properties.hibernate.dialect =  org.hibernate.dialect.MySQL8Dialect

In my case the issue was multiparted and related to AWS:

as @Tareq Islam pointed out setting the dialect in application.properties helped. I used for MySQL 5.6:

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL55Dialect
the second issue after this was that the JDBC was not able to connect to the server due to change in SSL connection encryption. I fixed it with help of

SSLHandShakeException No Appropriate Protocol

But I needed to enable TLS1.0 by setting to /etc/java-11-openjdk/security/java.security

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL

In my case, I have set ddl-auto as validate, in application.properties file

spring.jpa.hibernate.ddl-auto=validate

Here, the issue occurs when property hibernate.hbm2ddl.auto is set to validate. Everything works fine when it is set to none. I think validator doesn't take into account that when primary key is defined as GENERATED BY DEFAULT AS IDENTITY.

I faced the same issue and found out that, it was a problem with the database schema not being correctly created.

I managed to solve this by creating a schema.

Steps:

Delete the database
Run the SQL script to create a schema
