Redis在3.0版本时引入redis集群的技术 * Redis集群解决了 1. 无论如何扩展redis集群,在代码中无需修改,继续使用旧配置; 2. redis集群支持手动迁移数据,而且无需知道底层算法,维护人员手动迁移数据;而且可以控制迁移数量 ### Redis集群架构 ### * ![k2UffrT.png][] * 注 * 对于客户端,连接redis集群无需配置全部ip和端口最少配置一个就可以,分布式不是代码维护而是 * 集群内部管理数据分布; * 内部数据key-value的传递过程是根据一个0-16383(16384)槽道，内部的数据重定向(data redirect) * 这样一个结构可以改变扩容和收缩时修改代码配置的问题; * 迁移工作为什么不需要在集群中使用代码完成? * 在集群中所有的key真正映射关系和redis节点本身无关,只和槽道号有关,需要数据迁移时,不能直接对key-value对数据操作,而是将槽道进行重新分配(reshard)集群中的所有数据将会根据重新计算的槽道管理内容进行重新转发保存(迁移的过程类似于修改数据加锁的过程,不能再迁移时进行数据操作) * 迁移步骤 1. 计算槽道号 2. 管理槽道号变化 3. 重新计算key哈希取模 * 在redis集群中,可以调用迁移命令来reshard数据槽道号;所以无需代码客户端调用程序重新分配数据 * 每一个节点都维护2个信息 1. 个是16384位的位序列16384bit的二进制 2. 每个节点都维护一个16384个元素的数组 * ![dhkDpRz.png][] ### reshard分片过程中,位序列和数组的变化 ### * 位序列先计算,变化,每一个变动槽道号的master节点的位序列 * 例子:7001 400-500;然后将这101个槽道挪走了挪到7002 1. 位序列变化 400-500节点从1编程0; 2. 数组信息 400-500的元素清空; 3. 7002 接收400-500; 4. 然后位序列中的400-500位从0变成1; 5. 将共享数组的400-500元素赋值,自己的值 ### 主从从复制,主宕从顶的特点 ### * 复制主节点的key-value数据位序列为0 * 共享数组也存在从节点 * 主从替换,7001主,7003从 * 位序列不一样,数据一样,数组一样 * 7003顶替的过程 1. 将数组进行分析 2. 是7001的获取下标,计算位序列 3. 根据位序列修改数组,将位序列是1的下标对应更新数组元素 4. 数组同步复制 * 数据的重新计算: 1. 主从替换时,数据完全不用动 2. reshard过程完成后,所有key重新计算,根据转发逻辑,改转发的转发,改保留的保留 # 集群与京淘的结合 # * 引入配置文件 * applicationContext-rediscluster.xml * redis-cluster.properties * 具体文件代码 * applicationContext-rediscluster.xml # #

RedisCluster实现了工厂bean的逻辑,初始化jedisCluster对象,经过初始化的这个对象可以直接注入使用BeanFactory # 前台搭建 # ### 考虑若干个问题 ### * 前台有没有数据访问的需求? * 相当大的数据访问需求 * 前台的数据从哪来? * 数据库做第一次访问需求,redis/缓存做后续的访问 * 前台能否直接连通数据库请求数据? * 从技术角度考虑,完全可以 * 从安全,业务需求,整体架构,不能访问数据库; * 连通数据库访问数据,在一个整体项目中,尽量保持架构的一个通道原则;多通道访问相同数据源容易造成数据混乱交叉; * 数据从哪来? * 数据需要跨系统访问获取 * 如何跨系统访问数据? * 引入三个技术,来跨系统访问数据 ### 前台搭建步骤 ### 1. maven工程创建(修改四处) 2. 引入架构配置文件 课前资料-基础框架-配置文件--前台 3. 引入静态资源web.xml 课前资料\\01-基础框架\\03-静态资源 4. 继承parent,依赖common ### 完成前台首页 ### * 前台的访问地址:http://www.jt.com/index.html * 看似是一个静态访问地址,实际是动态的可以被web的map转发给springmvc框架,最终由controller- - 处理请求 * 为什么要使用貌似静态的一个文件访问来做首页地址呢? * 查看京东商品发现也是使用html结尾的 * https://item.jd.com/3726830.html * 主流爬虫机器人,都大部分爬取的是静态网页资源; * 实现controller的首页跳转 * Indexcontroller ### 前台商品分类树展示 ### * 前台商品分类树的展示,只请求一次数据; * 所以一次请求,将会把所有的数据全部传递给前台页面的js代码 * 在数据中必须体现层级关系(三层) * 需要一个json字符串,字符串中保存所有商品分类的层级关系 * 图示 * ![D8mlSYW.png][] * json字符串 # # { "data": [{ "u": "/products/1.html", "n": "<a
