mybatis + memcache 配置
项目中用到Cache, 研究了一下,配置一下Memcached+mybatis.
英文URL:http://mybatis.github.io/memcached-cache/ 。引用了原作,谢谢。
pom文件引用
<dependency> <groupId>org.mybatis.caches</groupId> <artifactId>mybatis-memcached</artifactId> <version>1.0.0</version> </dependency>
也可以上github上下载https://github.com/mybatis/memcached-cache/releases
http://mybatis.github.io/memcached-cache/ 这个是说明
在mapper中配置
<mapper namespace="org.acme.FooMapper"> <cache type="org.mybatis.caches.memcached.MemcachedCache" /> ... </mapper>
memcache的配置是根据classpath下的 /memcached.properties 配置的,如果没有使用默认
Property | Default | Description |
org.mybatis.caches.memcached.keyprefix | _mybatis_ | 缓存key的前缀 |
org.mybatis.caches.memcached.servers | localhost:11211 | memcache配置 ${host}:${port} |
org.mybatis.caches.memcached.connectionfactory | net.spy.memcached. DefaultConnectionFactory | 只要是实现接口 net.spy.memcached. ConnectionFactory |
org.mybatis.caches.memcached.expiration | 过期时间 | 单位是秒 |
org.mybatis.caches.memcached.asyncget | false | 是否启用异步读 |
org.mybatis.caches.memcached.timeout | 5 | 使用异步读的timeout时间 |
org.mybatis.caches.memcached.timeoutunit | java.util.concurrent. TimeUnit.SECONDS | timeout单位 |
org.mybatis.caches.memcached.compression | false | 如果开启,对象在放到 memcache前会使用GZIP 压缩 |
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>
