Spring boot - Not a managed type

I use Spring boot+JPA and having a problem while starting the service. ``` Caused by: java.lang.IllegalArgumentException: Not an managed type: class com.nervytech.dialer.domain.PhoneSettings at org.hibernate.jpa.internal.metamodel.MetamodelImpl.managedType(MetamodelImpl.java:219) at org.springframework.data.jpa.repository.support.JpaMetamodelEntityInformation.<init>(JpaMetamodelEntityInformation.java:68) at org.springframework.data.jpa.repository.support.JpaEntityInformationSupport.getMetadata(JpaEntityInformationSupport.java:65) at org.springframework.data.jpa.repository.support.JpaRepositoryFactory.getEntityInformation(JpaRepositoryFactory.java:145) at org.springframework.data.jpa.repository.support.JpaRepositoryFactory.getTargetRepository(JpaRepositoryFactory.java:89) at org.springframework.data.jpa.repository.support.JpaRepositoryFactory.getTargetRepository(JpaRepositoryFactory.java:69) at org.springframework.data.repository.core.support.RepositoryFactorySupport.getRepository(RepositoryFactorySupport.java:177) at org.springframework.data.repository.core.support.RepositoryFactoryBeanSupport.initAndReturn(RepositoryFactoryBeanSupport.java:239) at org.springframework.data.repository.core.support.RepositoryFactoryBeanSupport.afterPropertiesSet(RepositoryFactoryBeanSupport.java:225) at org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean.afterPropertiesSet(JpaRepositoryFactoryBean.java:92) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1625) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1562) ``` Here is the Application.java file, ``` @Configuration @ComponentScan @EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class }) @SpringBootApplication public class DialerApplication { public static void main(String[] args) { SpringApplication.run(DialerApplication.class, args); } } ``` I use UCp for connection pooling and the DataSource configuration is below, ``` @Configuration @ComponentScan @EnableTransactionManagement @EnableAutoConfiguration @EnableJpaRepositories(entityManagerFactoryRef = "dialerEntityManagerFactory", transactionManagerRef = "dialerTransactionManager", basePackages = { "com.nervy.dialer.spring.jpa.repository" }) public class ApplicationDataSource { /** The Constant LOGGER. */ private static final Logger LOGGER = LoggerFactory .getLogger(ApplicationDataSource.class); /** The Constant TEST_SQL. */ private static final String TEST_SQL = "select 1 from dual"; /** The pooled data source. */ private PoolDataSource pooledDataSource; ``` UserDetailsService Implementation, ``` @Service("userDetailsService") @SessionAttributes("user") public class UserDetailsServiceImpl implements UserDetailsService { @Autowired private UserService userService; ``` Service layer implementation, ``` @Service public class PhoneSettingsServiceImpl implements PhoneSettingsService { } ``` The repository class, ``` @Repository public interface PhoneSettingsRepository extends JpaRepository<PhoneSettings, Long> { } ``` Entity class, ``` @Entity @Table(name = "phone_settings", catalog = "dialer") public class PhoneSettings implements java.io.Serializable { ``` WebSecurityConfig class, ``` @Configuration @EnableWebMvcSecurity @ComponentScan public class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private UserDetailsServiceImpl userDetailsService; /** * Instantiates a new web security config. */ public WebSecurityConfig() { super(); } /** * {@inheritDoc} * @see org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter#configure(org.springframework.security.config.annotation.web.builders.HttpSecurity) */ @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/login", "/logoffUser", "/sessionExpired", "/error", "/unauth", "/redirect", "*support*").permitAll() .anyRequest().authenticated().and().rememberMe().and().httpBasic() .and() .csrf() .disable().logout().deleteCookies("JSESSIONID").logoutSuccessUrl("/logoff").invalidateHttpSession(true); } @Autowired public void configAuthentication(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder()); } } ``` The packages are as follows, - `Application` class is in - `com.nervy.dialer` - `Datasource` class is in - `com.nervy.dialer.common` - Entity classes are in - `com.nervy.dialer.domain` - Service classes are in - `com.nervy.dialer.domain.service.impl` - Controllers are in - `com.nervy.dialer.spring.controller` - Repository classes are in - `com.nervy.dialer.spring.jpa.repository` - `WebSecurityConfig` is in - `com.nervy.dialer.spring.security` Thanks
