  • Why are you excluding "DataSourceAutoConfiguration"? Remove @EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class}) from your main class. Actually you do not need these two @EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class}) @EnableJpaRepositories(basePackages = {"com.cg.pps.repository"}). For more info please refer https://stackoverflow.com/questions/48416927/spring-boot-required-a-bean-named-entitymanagerfactory-that-could-not-be-foun/54663039 – P.Sanjay Dec 30 '20 at 17:33
  • @P.Sanjay when I removed these lines.It is giving me a new error (Error creating bean with name 'inMemoryDatabaseShutdownExecutor ).Above I have included my Pom.xml file too – Muskan Ali Dec 31 '20 at 07:54
  • Are you doing manual configuration for JPA? If yes, then you need to define your bean with entity manage factory like this @Bean(name="entityManagerFactory") public LocalSessionFactoryBean sessionFactory() { LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); return sessionFactory; } If still there is problem, then looks like there is some problem with your datasource configuration. please provide your db configs. Also did you check the link which i had mentioned in my previous commnet. – P.Sanjay Dec 31 '20 at 11:12
  • @P.Sanjay I got the error. It was in Repository file.In this method (public boolean existByEmail(String email);).The definition of this method was wrong. I replaced it with this. @Query("SELECT CASE WHEN COUNT(u) > 0 THEN 'true' ELSE 'false' END FROM CandidateCv u WHERE u.email = ?1") public Boolean existsByEmail(String email); – Muskan Ali Jan 04 '21 at 10:48
