监听类中,监听商品数据库的tb_spu的数据变化,当数据变化的时候生成静态页或者删除静态页

@Autowired
private PageFeign pageFeign;

@ListenPoint(destination = "example",
        schema = "changgou_goods",
        table = {"tb_spu"},
        eventType = {CanalEntry.EventType.UPDATE, CanalEntry.EventType.INSERT, CanalEntry.EventType.DELETE})

    //判断操作类型
    if (eventType == CanalEntry.EventType.DELETE) {
        String spuId = "";
        List<CanalEntry.Column> beforeColumnsList = rowData.getBeforeColumnsList();
        for (CanalEntry.Column column : beforeColumnsList) {
            if (column.getName().equals("id")) {
                spuId = column.getValue();//spuid
                break;
            }
        }
        //todo 删除静态页

    }else{
        //新增 或者 更新
        List<CanalEntry.Column> afterColumnsList = rowData.getAfterColumnsList();

            }
        }
