I am not sure if you can do that using JDBC template alone. Maybe you could invoke the batchUpdate
method in steps, by slicing up the big list into batch-sized chunks.
Have a look here:
@Override
public void saveBatch(final List<Employee> employeeList) {
final int batchSize = 500;
for (int j = 0; j < employeeList.size(); j += batchSize) {
final List<Employee> batchList = employeeList.subList(j, j + batchSize > employeeList.size() ? employeeList.size() : j + batchSize);
getJdbcTemplate().batchUpdate(QUERY_SAVE,
new BatchPreparedStatementSetter() {
@Override
public void setValues(PreparedStatement ps, int i)
throws SQLException {
Employee employee = batchList.get(i);
ps.setString(1, employee.getFirstname());
ps.setString(2, employee.getLastname());
ps.setString(3, employee.getEmployeeIdOnSourceSystem());
}
@Override
public int getBatchSize() {
return batchList.size();
}
});
}
}
