shardingjdbc 强制路由走主库查询实时数据 避免主从同步数据延迟

@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 分页插件类似  只作用于最近的一条查询语句，
    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;
}
