Använd batchinlägg på detta sätt:
try {
connection con.setAutoCommit(false);
PreparedStatement prepStmt = con.prepareStatement(
"insert into product(code,name,price,available) values (?,?,?,?");
Iterator<Product> it = li.iterator();
while(it.hasNext()){
Product p = it.next();
prepStmt.setString(1,p.getCode());
prepStmt.setString(2,p.getCode());
prepStmt.setInt(3,p.getPrice());
prepStmt.setBoolean(4,p.isAvailable());
prepStmt.addBatch();
}
int [] numUpdates=prepStmt.executeBatch();
for (int i=0; i < numUpdates.length; i++) {
if (numUpdates[i] == -2)
System.out.println("Execution " + i +
": unknown number of rows updated");
else
System.out.println("Execution " + i +
"successful: " + numUpdates[i] + " rows updated");
}
con.commit();
} catch(BatchUpdateException b) {
// process BatchUpdateException
}
