這裡以MySQL資料庫為例來展示四種通過jdbc實現批處理的四種方法，這裡只舉例了插入100條資料的寫法，其他大致相同。

第一種：最簡單，最好理解的（不要這樣寫）
（沒工作經驗可能會這樣寫，執行效率最低）

public class jdbcDemo1 {
    public static void main(String[] args) throws Exception{
        Connection con = null;
        Class.forName("com.mysql.jdbc.Driver");
        con = DriverManager.getConnection("url"
 
, "user", "password");
        PreparedStatement ins = null;

        Date date = new Date();
        System.out.println(date.getTime());

        for (int i = 1; i <= 100; i++) {
            String sql = "insert into t_test (id,user) values (?,?)";
            ins = con.prepareStatement(sql);
            ins.setInt(1
 
, i);
            ins.setInt(2, i);
            ins.execute();
        }
        Date dateTwo = new Date();
        System.out.println(dateTwo.getTime());
    }
}

第二種：使用事務，不自動commit（常用的吧）

public class jdbcDemo1 {
    public static void main(String[] args) throws Exception{
        Connection con = null
 
;
        Class.forName("com.mysql.jdbc.Driver");
        con = DriverManager.getConnection("url", "user", "password");
        PreparedStatement ins = null;

        int COMMIT_SIZE = 200;
        con.setAutoCommit(false);
        PreparedStatement ins = null;

        Date date = new Date();
        System.out.println(date.getTime());

        for (int i = 101; i <= 200; i++) {
            String sql = "insert into t_test (id,user) values (?,?)";
            ins = con.prepareStatement(sql);
            ins.clearParameters();
            ins.setInt(1, i);
            ins.setInt(2, i);
            ins.execute();
            if (i % COMMIT_SIZE == 0) {
                con.commit();     
            } con.commit(); 
        }
        Date dateTwo = new Date();
        System.out.println(dateTwo.getTime());
    }
}

第三種： executeBatch（推薦）

public class jdbcDemo1 {
    public static void main(String[] args) throws Exception{    
        Connection con = null;
        Class.forName("com.mysql.jdbc.Driver");
        con = DriverManager.getConnection("url", "user", "password");
        PreparedStatement ins = null;   

        int COMMIT_SIZE = 100;
        int BATCH_SIZE = 100;
        String sql = "insert into t_test1 (id,data) values (?,?)";
        con.setAutoCommit(false);
        PreparedStatement ins = null;
        ins = con.prepareStatement(sql);

        Date date = new Date();
        System.out.println(date.getTime());

        for (int i = 101; i <= 200; i+= BATCH_SIZE) {
            ins.clearBatch();
            for (int j = 0; j < BATCH_SIZE; j++){
                ins.setInt(1, i+j);
                ins.setInt(2, j);
                ins.addBatch();
            }
            ins.executeBatch();
            if ((i + BATCH_SIZE - 1) % COMMIT_SIZE == 0) {
                con.commit();     
            } 
        }
            con.commit();

            Date dateTwo = new Date();
            System.out.println(dateTwo.getTime());
    }
}

第四種：先load再commit（速度最快）
（這樣寫最快。但是有些小瑕疵，sql不安全，需要改寫一部分）
為什麼不安全是因為這個sql是拼出來的，要改成之前寫的（？，？）就可以了。

public class jdbcDemo1 {
    public static void main(String[] args) throws Exception{    
        Connection con = null;
        Class.forName("com.mysql.jdbc.Driver");
        con = DriverManager.getConnection("url", "user", "password");
        PreparedStatement ins = null;   

        int COMMIT_SIZE = 400;
        PreparedStatement ins =null;
        con.setAutoCommit(false);

        Date date = new Date();
        System.out.println(date.getTime());

        ins = con.prepareStatement("load data local infile '' "
                    + "into table t_test fields terminated by ','");
        StringBuilder sb = new StringBuilder();
        for (int i = 304; i <= 404; i++) {
            sb.append(i + "," + i + "\n");
            if(i % commitSize == 0){
                InputStream is=new ByteArrayInputStream(sb.toString()
                                .getBytes());
                ((com.mysql.jdbc.Statement) ins)
                                .setLocalInfileInputStream(is);
                ins.execute();
                con.commit();
                sb.setLength(0);
            }
        }
        InputStream is=new ByteArrayInputStream(sb.toString().getBytes());
        ((com.mysql.jdbc.Statement) ins).setLocalInfileInputStream(is);
        ins.execute();
        con.commit();

        Date dateTwo = new Date();
        System.out.println(dateTwo.getTime());
    }
}
