视频中到这里就可以运行了，不过我applicationContext.xml出错了。。。

一会多个叉一会少个叉。。。。不管了，理论上就算这里有叉也是可以运行的，大概我哪里又拼写错了。

拷贝一份Struts到config.struts包中，改名为user.xml

理论上的运行结果如下，然而我上面的问题都没解决，进行不到这里

等等，叉解决了，可能是因为我挪动了jar包，点edit修改后重启eclipse就没叉了。不过，还是不知道哪里有问题，估计是配置文件写错字母了。

(三）Redis数据类型之hash类型_Origin_afan的博客-程序员秘密

Hash类型存储的困惑对象类数据的存储如果具有较为频繁的更新需求操作会显得笨重因为第一个拿数据容易，但是更新数据难，需要整个覆盖掉。然而hash的话，就将外面的user????xxxx作为key，存储空间的name作为field（属性），然后剩下的就作为value，然后要访问指定字段，就访问对应的属性即可。hash类型新的存储需求：对一系列存储的数据进行编组，方便管理，典型应用存储对象信息需要的内存结构：一个存储空间保存多少个键值对数据hash类型：底层使用哈希表结构实现数据存储ha
