mybatis-memcached框架配置

官方放出了mybatis和memcached的整合包，先附上官方文档地址

http://mybatis.github.io/memcached-cache/

文档很简洁，事实证明使用起来也很简单

memcached的安装我这里就不再讲了，网上很容易找到

在项目中引入

    org.mybatis.caches
    mybatis-memcached
    1.0.0
  

然后在想使用的mapper中加入

  
  ...

就可以用了

再建一个memcached.properties，对他进行配置

Property	Default	Description
org.mybatis.caches.memcached.keyprefix	_mybatis_	any string identifier
org.mybatis.caches.memcached.servers	localhost:11211	space separated list of ${host}:${port}
org.mybatis.caches.memcached.connectionfactory	net.spy.memcached.DefaultConnectionFactory	Any class that implementsnet.spy.memcached.ConnectionFactory
org.mybatis.caches.memcached.expiration	the number of seconds in 30 days	the expiration time (in seconds)
org.mybatis.caches.memcached.asyncget	false	flag to enable/disable the async get
org.mybatis.caches.memcached.timeout	5	the timeout when using async get
org.mybatis.caches.memcached.timeoutunit	java.util.concurrent.TimeUnit.SECONDS	the timeout unit when using async get
org.mybatis.caches.memcached.compression	false	if true, objects will be GZIP compressed before putting them to Memcached

我简单测试了一下发现它可以配置多个服务器，用逗号分隔，经测试如果某一台挂掉，他会选择正常的那台

如果2台都挂掉，就会报错,估计我们还是希望在memcached服务器挂掉后从数据库读取数据，不知道大家有什么好的实现方式或者思路吗

org.mybatis.caches.memcached.servers=172.29.33.201:11211,localhost:11211
org.mybatis.caches.memcached.expiration=30 
org.mybatis.caches.memcached.asyncget=false
