# mysql 协议 binlog 解析

## SlaveConnector  远程连接 binlog event接收

```

SlaveConnector connector = new SlaveConnector(host, port, username, password);

connector.setServerId(5);

connector.addFilter(new EventFilter(new EventType[]{UPDATE_ROWS_EVENT, DELETE_ROWS_EVENT, WRITE_ROWS_EVENT}));

connector.addFilter(new DatabaseFilter(new String[]{"test"}));

connector.registerListener(event -> {

    try {

        System.out.println(event);

    } catch (Exception e) {

        e.printStackTrace();

    }

});

connector.registerListener(new EventListener() {

    @Override

    public void onEvent(BinlogEvent event) {

        try {

            System.out.println(JsonUtil.toString(event));

            System.out.println();

        } catch (JsonProcessingException e) {

            e.printStackTrace();

        }

    }

});

connector.startAndAwait();

connector.shutdown();

```

## binlog 文件解析

```

FileConnector connector = new FileConnector("/Users/stony/Downloads/my-bin.000032");

connector.setChecksumType(ChecksumType.CRC32);

//自定义过滤

connector.addFilter(new Filter() {

    @Override

    public boolean test(BinlogEvent event) {

        BinlogEvent.Event myEvent = event.getEvent();

        if ((myEvent instanceof RowsEvent) || (myEvent instanceof TableMapEvent)) {

            String dbName;

            String tName;

            if (myEvent instanceof RowsEvent) {

                dbName = ((RowsEvent) myEvent).getSchema();

                tName = ((RowsEvent) myEvent).getTableName();

            } else {

                dbName = ((TableMapEvent) myEvent).getSchema();

                tName = ((TableMapEvent) myEvent).getTable();

            }

            if (dbName != null && "employees".equals(dbName)) {

                if (tName != null && "employees".equals(tName)) {

                    return true;

                }

            }

        }

        return false;

    }

});

connector.registerListener(event -> {

    try {

        System.out.println(event);

    } catch (Exception e) {

        e.printStackTrace();

    }

});

connector.startAndAwait();

connector.shutdown();
