In this program we didnot wrote getter and constructor in AccountService class . Then how jdbcTemplate is beeing injected in this class?

    package sinha.priyank.txn;

    import org.springframework.jdbc.core.simple.SimpleJdbcDaoSupport;
    import org.springframework.transaction.annotation.Propagation;
    import org.springframework.transaction.annotation.Transactional;
    // How we are injecting JdbcTemplet in this class as we dont have    //any getter/setter and constructor
    @Transactional
    public class AccountService extends SimpleJdbcDaoSupport {

        @Transactional(propagation=Propagation.REQUIRED,timeout=10)
        public void deposit(int accountNumber , double amount)
            {
                getSimpleJdbcTemplate().update("update accounts set balance=balance+? where account_number=?", amount,accountNumber);
                getSimpleJdbcTemplate().update("insert into statements (account_number,transaction_amount,transaction_type,id) values(?,?,?,?)", accountNumber , amount , "Deposit",121);
            }

        @Transactional(propagation=Propagation.REQUIRES_NEW , timeout=40)
        public void withdraw(int accountNumber , double amount)
            {
                getSimpleJdbcTemplate().update("update accounts set balance=balance+? where account_number=?", amount,accountNumber);
                getSimpleJdbcTemplate().update("insert into statements (account_number,transaction_amount,transaction_type,id) values(?,?,?,?)", accountNumber , amount , "Withdraw",180);
            }
    }
