Spring boot 2.0.0.M4 required a bean named 'entityManagerFactory' that could not be found

With the version of spring-boot 2.0.0.M4 I have this issue: Description:

Field userRepository in webroot.websrv.auth.service.JwtUserDetailsServiceImpl required a bean named 'entityManagerFactory' that could not be found. Action: Consider defining a bean named 'entityManagerFactory' in your configuration. [WARNING] java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at ... Caused by: org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'jwtUserDetailsServiceImpl': Unsatisfied dependency expressed through method 'setUserRepository' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Cannot create inner bean '(inner bean)#770f146b' of type [org.springframework.orm.jpa.SharedEntityManagerCreator] while setting bean property 'entityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#770f146b': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' available


Spring boot application start:

package webroot.websrv; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class WebcliApplication { public static void main(String[] args) { SpringApplication.run(WebcliApplication.class, args); } }

The implemented Jwt service JwtUserDetailsServiceImpl:

@Service public class JwtUserDetailsServiceImpl implements UserDetailsService {

@Autowired private UserRepository userRepository; /** * Injects UserRepository instance * @param userRepository to inject */ @Autowired public void setUserRepository(UserRepository userRepository) { this.userRepository = userRepository; }


Here the UserRepository:

package webroot.websrv.auth.repository; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.stereotype.Repository; import webroot.websrv.auth.entity.User; @Repository public interface UserRepository extends JpaRepository<User, Long> { /** * Finds user by email * @param email to look for * @return user by given email */ User findByEmail(String email); /** * Finds user by name * @param name to look for * @return user by given name */ User findByName(String name); }

I have saw several time this issue reported here but most of the cases I have it OK for the given solutions.

Do I have to explicit define a bean to the entity manager ? It should be automatically injected no ?

I added the class for the UserRepository it extends a JpaRepository.




I found the solution, it was necessary to implement a JpaConfiguration:

@Configuration @EnableJpaRepositories(basePackages = "webroot.webserv", entityManagerFactoryRef = "entityManagerFactory", transactionManagerRef = "transactionManager") @EnableTransactionManagement public class JpaConfiguration { @Autowired private Environment environment; @Value("${datasource.sampleapp.maxPoolSize:10}") private int maxPoolSize; /* * Populate SpringBoot DataSourceProperties object directly from application.yml * based on prefix.Thanks to .yml, Hierachical data is mapped out of the box with matching-name * properties of DataSourceProperties object]. */ @Bean @Primary @ConfigurationProperties(prefix = "spring.datasource") public DataSourceProperties dataSourceProperties(){ return new DataSourceProperties(); } /* * Configure HikariCP pooled DataSource. */ @Bean public DataSource dataSource() { DataSourceProperties dataSourceProperties = dataSourceProperties(); HikariDataSource dataSource = (HikariDataSource) org.springframework.boot.jdbc.DataSourceBuilder .create(dataSourceProperties.getClassLoader()) .driverClassName(dataSourceProperties.getDriverClassName()) .url(dataSourceProperties.getUrl()) .username(dataSourceProperties.getUsername()) .password(dataSourceProperties.getPassword()) .type(HikariDataSource.class) .build(); dataSource.setMaximumPoolSize(maxPoolSize); return dataSource; } /* * Entity Manager Factory setup. */ @Bean public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws NamingException { LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean(); factoryBean.setDataSource(dataSource()); factoryBean.setPackagesToScan(new String[] { "webroot.websrv" }); factoryBean.setJpaVendorAdapter(jpaVendorAdapter()); factoryBean.setJpaProperties(jpaProperties()); return factoryBean; } /* * Provider specific adapter. */ @Bean public JpaVendorAdapter jpaVendorAdapter() { HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter(); return hibernateJpaVendorAdapter; } /* * Here you can specify any provider specific properties. */ private Properties jpaProperties() { Properties properties = new Properties(); properties.put("hibernate.dialect", environment.getRequiredProperty ("spring.jpa.properties.hibernate.dialect") ); ... return properties; } @Bean @Autowired public PlatformTransactionManager transactionManager(EntityManagerFactory emf) { JpaTransactionManager txManager = new JpaTransactionManager(); txManager.setEntityManagerFactory(emf); return txManager; } } Thanks for the suggestions.
