spring boot - Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type

Question

I am trying to create JPA repository with Driver class, but getting "Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type" Please find below code.

package org.codejudge.sb.config;

@Configuration
public class WebConfiguration {
    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**");
            }
        };
    }

    @Bean
    public JpaTransactionManager transactionManager(EntityManagerFactory emf, DataSource dataSource){
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(emf);
        transactionManager.setDataSource(dataSource);
        return transactionManager;
    }

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://127.0.0.1:3306/db?useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false");
        dataSource.setUsername("root");
        dataSource.setPassword("admin");
        return  dataSource;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(dataSource);
//        em.setPersistenceUnitName("org.hibernate.jpa.HibernatePersistenceProvider");
        em.setPackagesToScan("data");
        em.setJpaVendorAdapter(jpaVendorAdapter);
        em.setJpaProperties(additionalProperties());
        return em;
    }

    Properties additionalProperties() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        return properties;
    }

    @Bean
    public JpaVendorAdapter jpaVendorAdapter(){
        HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
        //adapter.setDatabase();
        adapter.setShowSql(true);
        adapter.setGenerateDdl(false);
        adapter.setDatabasePlatform("org.hibernate.dialect.HSQLDialect");
        return adapter;
    }
