mybatis整合memcache

We have just released the 1st GA version of the MyBatis Memcached adapter.

The beta has bee around for almost one year and only one issue was reported.

這個memcache的整合是官方發佈的版本，在網上找了找都沒看到相關介紹，我此次也當次搬運工

pom文件引用

<dependency>
    <groupId>org.mybatis.caches</groupId>
    <artifactId>mybatis-memcached</artifactId>
    <version>1.0.0</version>
  </dependency>

也能夠上github上下載https://github.com/mybatis/memcached-cache/releases

http://mybatis.github.io/memcached-cache/ 這個是說明

在mapper中配置

<mapper namespace="org.acme.FooMapper">
  <cache type="org.mybatis.caches.memcached.MemcachedCache" />
  ...
</mapper>

memcache的配置是根據classpath下的 /memcached.properties 配置的，若是沒有使用默認

Property	Default	Description
org.mybatis.caches.memcached.keyprefix	_mybatis_	緩存key的前綴
org.mybatis.caches.memcached.servers	localhost:11211	memcache配置${host}:${port}
org.mybatis.caches.memcached.connectionfactory	net.spy.memcached.DefaultConnectionFactory	只要是實現接口net.spy.memcached.ConnectionFactory
org.mybatis.caches.memcached.expiration	過時時間	單位是秒
org.mybatis.caches.memcached.asyncget	false	是否啓用異步讀
org.mybatis.caches.memcached.timeout	5	使用異步讀的timeout時間
org.mybatis.caches.memcached.timeoutunit	java.util.concurrent.TimeUnit.SECONDS	timeout單位
org.mybatis.caches.memcached.compression	false	若是開啓，對象在放到memcache前會使用GZIP 壓縮

If users need to log cache operations, they can plug the Cache logging version:

<mapper namespace="org.acme.FooMapper">
  <cache type="org.mybatis.caches.memcached.LoggingMemcachedCache" />
  ...
</mapper>

還沒看代碼是怎麼實現的，是否是能夠實現那種hibernate的二級緩存功能
