//insert batch example
public void insertBatch(final List<Customer> customers){
	String sql = "INSERT INTO CUSTOMER " +
		"(CUST_ID, NAME, AGE) VALUES (?, ?, ?)";
			
	List<Object[]> parameters = new ArrayList<Object[]>();
       
	for (Customer cust : customers) {
        parameters.add(new Object[] {cust.getCustId(), 
            cust.getName(), cust.getAge()}
        );
    }
    getSimpleJdbcTemplate().batchUpdate(sql, parameters);        
}

//insert batch example with SQL
public void insertBatchSQL(final String sql){
		
	getJdbcTemplate().batchUpdate(new String[]{sql});
		
}
