  • Batch Insert with jdbcTemplate and BatchPreparedStatementSetter


    I have a question on batch operations using JdbcTemplate and BatchPreparedStatementSetter. In the code given here, all the 2000 records are inserted in a single batch operation. I don't want to insert all the 2000 records at one go. Instead, I want to insert in batches of 10 records. How do I achieve that? I'm brand new to Spring Framework. Please help me..

    JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
        final int count = 2000;
        final List<String> firstNames = new ArrayList<String>(count);
        final List<String> lastNames = new ArrayList<String>(count);
        for (int i = 0; i < count; i++) {
          firstNames.add("First Name " + i);
          lastNames.add("Last Name " + i);
                "insert into customer (id, first_name, last_name, last_login, comments) values (?, ?, ?, ?, ?)",
                new BatchPreparedStatementSetter() {
                  public void setValues(PreparedStatement ps, int i) throws SQLException {
                    ps.setLong(1, i + 10);
                    ps.setString(2, firstNames.get(i));
                    ps.setString(3, lastNames.get(i));
                    ps.setNull(4, Types.TIMESTAMP);
                    ps.setNull(5, Types.CLOB);
                  public int getBatchSize() {
                    return count;

    I believe a call to batchUpdate() corresponds to exactly one batch. If you want to chunk your batches into something smaller than the set size, you'd have to loop over records and issue a batchUpdate() for each group of 10. In that case, your getBatchSize() becomes <=10 with the final iteration probably being less than 10.

    Hope that helps.
