Flink写Mysql

Flink 自带了JDBCOutputFormat来写入Mysql

 FlinkKafkaConsumer011<String> consumer011 = new FlinkKafkaConsumer011<String>("flink_order", new SimpleStringSchema(), props);
        DataStream<String> stream = env.addSource(consumer011);
        stream.map(new MapFunction<String, Row>() {

            @Override
            public Row map(String s) throws Exception {
                System.out.println(s);
                Row row = new Row(3);
                int va=1;
                row.setField(0, va);
                row.setField(1, va);
                row.setField(2, va);
                return row;
            }
        }).writeUsingOutputFormat(JDBCOutputFormat.buildJDBCOutputFormat()
                .setDrivername("com.mysql.jdbc.Driver")
                .setDBUrl("jdbc:mysql://xx")
                .setUsername("xx")
                .setPassword("xx")
                .setQuery("insert into order_cnt(cnt,user,num) values(?,?,?)")
                .setSqlTypes(new int[]{Types.INTEGER, Types.INTEGER, Types.INTEGER})
                .finish());

        try {
            env.execute("flink-test");
        } catch (Exception e) {
            e.printStackTrace();
        }
