org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]
Here is my pom.xml

</project>
and this is my SecurityConfig.java
#EnableGlobalMethodSecurity(prePostEnabled = true)
#EnableWebSecurity
#EnableJpaRepositories(basePackageClasses = UsersRepository.class)
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private MyUserDetailsService myUserDetailsService;

#Override
public String encode(CharSequence charSequence) {
return charSequence.toString();
}
#Override
public boolean matches(CharSequence charSequence, String s) {
return true;
}
};
}
}
this is my Users.java
#Entity
#Table(name = "user")
public class Users {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "user_id")
private int id;
#Column(name = "login")
private String login;
#Column(name = "password")
private String password;

public Users() {
}
public Users(Users users){
this.id=users.getId();
this.login=users.getLogin();

}
public int getId() {
return id;
}
public void setId(int id) {

public String getLogin() {

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

public String getPassword() {

public void setPassword(String password) {
this.password = password;
}
public Set<Role> getRoles() {
return roles;
}
public void setRoles(Set<Role> roles) {
this.roles = roles;
}
}
this is the roles.java
#Entity
#Table(name = "role")
public class Role {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "role_id")
private int roleId;
#Column(name = "role")
private String role;
public Role() {
}
public int getRoleId() {
return roleId;
}
public void setRoleId(int roleId) {
this.roleId = roleId;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
}
this is my UsersRepository.java
#Repository
public interface UsersRepository extends JpaRepository<Users, Integer> {
Optional<Users> findByName(String username);
}
this is MyUserDetailsService.java
#Service
public class MyUserDetailsService implements UserDetailsService {
#Autowired
private UsersRepository usersRepository;
#Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
Optional<Users> optionalUsers = usersRepository.findByName(username);
optionalUsers
.orElseThrow(() -> new UsernameNotFoundException("Utilisateur Introuvable!"));
return optionalUsers
.map(MyUserDetails::new).get();
}
}
this is MyUserDetails.java
public class MyUserDetails extends Users implements UserDetails {
public MyUserDetails(final Users users) {
super(users);
}
#Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return getRoles()
.stream()

}
#Override
public String getPassword() {

#Override
public boolean isAccountNonExpired() {
return true;
}

public boolean isAccountNonLocked() {
return true;
}
#Override
public boolean isCredentialsNonExpired() {
return true;
}
#Override
public boolean isEnabled() {
return true;
}
}
and finally my controller of ressources AuthenticationCOntroller.java
#RequestMapping("/api")
#RestController
public class AuthentificationController {
#GetMapping(value = "/login")
public String hello() {
return "Hello World";
}
#PreAuthorize("hasAnyRole('ADMIN')")
#GetMapping("/admin/login")
public String helloAdmin() {
return "Hello ADMIN";
}
#GetMapping("/login/alternate")
public String alternate() {
return "alternate";
}
}
this is application.properties
spring.datasource.url=jdbc:mysql://localhost:3306/mydb
spring.datasource.username=root
spring.datasource.password =
spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
I'm using and MYSQL database it is well connected and the tables are created with some values.
Thank you and waiting for you answers.

Answer 1

if you are using java version 9+, add following too and remove hibernate core dependency as its already included in spring boot jpa starter.
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.1</version>
</dependency>

Answer 2

Remove the Hibernate dependency because spring-boot-starter-data-jpa already has it.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.0.7.Final</version>
</dependency>
Hope this works :)

Answer 3

There is a conflict in pom.xml dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
spring-boot-starter-jpa has hibernate-core dependency included.
It is possible to view the dependency graph of a project like so:
mvn dependency:tree
mvn dependency:list
These commands will show what version of Hibernate included in the compilation.
To fix the UnsatisfiedDependencyException of entityManagerFactory bean, simply delete hibernate-core dependency from the pom.xml
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.0.7.Final</version>
</dependency>
