1、 Memcache和Mybatis整合jar 下载： mybatis-memcached-1.0.0.jar

      maven project add: 

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

2. Add the following statement to the Mapper file:

copy code 
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper        PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN"  
"http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd">
<mapper namespace="com.xxx.dao.xxx" >
<cache type="org.mybatis.caches.memcached.LoggingMemcachedCache" />
  <resultMap id="xxx" type="com.xxx.xxx.xxx" >
    <id column="ID" property="id" jdbcType="BIGINT" />
  </resultMap>
copy code

There are two configuration modes: with log and without log:

No log
<cache type="org.mybatis.caches.memcached.MemcachedCache" />

With log
<cache type="org.mybatis.caches.memcached.LoggingMemcachedCache" />

3. Create a new memcached.properties file under the classpath with the following format:

#any string identifier

org.mybatis.caches.memcached.keyprefix=_biz-cache-wk_

#space separated list of ${host}:${port}

org.mybatis.caches.memcached.servers=192.168.0.200:12000

#org.mybatis.caches.memcached.servers=192.168.0.44:12000

#Any class that implementsnet.spy.memcached.ConnectionFactory

org.mybatis.caches.memcached.connectionfactory=net.spy.memcached.DefaultConnectionFactory

#the number of seconds in 30 days    the expiration time (in seconds)

org.mybatis.caches.memcached.expiration=6000

#flag to enable/disable the async get

org.mybatis.caches.memcached.asyncget=false

#the timeout when using async get

org.mybatis.caches.memcached.timeout=5

#the timeout unit when using async get

org.mybatis.caches.memcached.timeoutunit=java.util.concurrent.TimeUnit.SECONDS

#if true, objects will be GZIP compressed before putting them to

org.mybatis.caches.memcached.compression=false

 

#\u7f13\u5b58\u670d\u52a1\u5668\u5b95\u673a\u540e\u591a\u4e45\u4e0d\u4f7f\u7528memcached \u6beb\u79d2\u4e3a\u5355\u4f4d

#refuse time when connection refused

org.mybatis.caches.memcached.refuseperiod=1000

配置参数说明：

Property  Default  Description
 org.mybatis.caches.memcached.keyprefix  _mybatis_  缓存key的前缀
 org.mybatis.caches.memcached.servers  localhost:11211  memcache地址
 org.mybatis.caches.memcached.connectionfactory  net.spy.memcached.DefaultConnectionFactory  只要实现接口net.spy.memcached.ConnectionFactory
 org.mybatis.caches.memcached.expiration  2592000（30天的秒数）  过期时间单位秒
 org.mybatis.caches.memcached.asyncget  false  Whether to enable asynchronous read
 org.mybatis.caches.memcached.timeout  5  Use the timeout time of asynchronous read
 org.mybatis.caches.memcached.timeoutunit  java.util.concurrent.TimeUnit.SECONDS   Use timeout time unit for asynchronous read
 org.mybatis.caches.memcached.compression  false  If enabled, objects will be compressed using GZIP before being placed in the memcache
