Spring JdbcTemplate batchUpdate() 範例

//insert batch example
public void insertBatch(final List<Customer> customers){
		
  String sql = "INSERT INTO CUSTOMER " +
	"(CUST_ID, NAME, AGE) VALUES (?, ?, ?)";
			
  getJdbcTemplate().batchUpdate(sql, new BatchPreparedStatementSetter() {
			
	@Override
	public void setValues(PreparedStatement ps, int i) throws SQLException {
		Customer customer = customers.get(i);
		ps.setLong(1, customer.getCustId());
		ps.setString(2, customer.getName());
		ps.setInt(3, customer.getAge() );
	}
			
	@Override
	public int getBatchSize() {
		return customers.size();
	}
  });
}

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