shardingjdbc 強制路由走主庫查詢實時數據 避免主從同步數據延遲

@Bean
public shardingsphere.demo.entity.Order order(){
    shardingsphere.demo.entity.Order order=new Order();
    order.setId(new Random(100).nextLong());
    order.setOrderId(101);
    order.setUserId(6);
    orderMapper.insert(order);

    order.setId(new Random(100).nextLong());
    order.setOrderId(102);
    order.setUserId(5);
    orderMapper.insert(order);


    HintManager.getInstance().setMasterRouteOnly();  //-----------------------------------核心    跟pagehelper 分頁插件類似  只作用於最近的一條查詢語句，
    List<Order> byUserId = orderMapper.findByUserId(5);


    HintManager.getInstance().setMasterRouteOnly();
    List<Order> b2 = orderMapper.findByUserId(6);

    List<Long> longs=new ArrayList<>();
    longs.add(5L);
    longs.add(6L);

    HintManager.getInstance().setMasterRouteOnly();
    List<Order> bys = orderMapper.findBys(longs);

    Map map=new HashMap<>();
    map.put("min",5);
    map.put("max",6);
    //orderMapper.findByUserIdBetween(map);
    return order;
}
