    private final static Class<WebApplication> APPLICATION_CLASS = WebApplication.class;
    private static ApplicationContext ctx;
    @PersistenceContext

    @Autowired
    JdbcTemplate jdbcTemplate;
    static Connection connection;
    public static void main(String[] args) {        
        ctx = SpringApplication.run(WebApplication.class, args);
