spring中整合memcached,以及创建memcache的put和get方法

spring中整合memcached,以及创建memcache的put和get方法：

1：在项目中导入memcache相关的jar包

2：memcache在spring.xml的配置：

代码：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
    <!-- XMemcachedClientFactoryBean工厂配置-->
    <bean id="memcachedClient" class="net.rubyeye.xmemcached.utils.XMemcachedClientFactoryBean">
        <property name="servers" value="${memcache.servers}"/>
        <property name="weights" value="${memcache.servers.weight}"/>
        <property name="sessionLocator">
            <bean class="net.rubyeye.xmemcached.impl.KetamaMemcachedSessionLocator"/>
        </property>
        <property name="transcoder">
            <bean class="net.rubyeye.xmemcached.transcoders.SerializingTranscoder"/>
        </property>
        <property name="bufferAllocator">
            <bean class="net.rubyeye.xmemcached.buffer.SimpleBufferAllocator"/>
        </property>
    </bean>
    <!--自己封装的api类-->
    <bean class="com.floor.shop.map.MemcachedAccess">
        <property name="memcachedClient" ref="memcachedClient"/>
    </bean>
</beans>

3：memcache在db.properties中的配置：

4：在spring的主配置文件中引入memcache的相关配置：

5：自己封装好的memcache方法（get(),   put(),  flushAll() ）

package com.floor.shop.map;

import net.rubyeye.xmemcached.MemcachedClient;
import net.rubyeye.xmemcached.exception.MemcachedException;

import java.util.concurrent.TimeoutException;

public class MemcachedAccess {
    private MemcachedClient memcachedClient;
    /*
     * 将memcachedClient交给spring管理
     * （就需提供下面的get和set方法）
     */
    public MemcachedClient getMemcachedClient() {
        return memcachedClient;
    }

    public void setMemcachedClient(MemcachedClient memcachedClient) {
        this.memcachedClient = memcachedClient;
    }

    /*
     *   memcache基于HashMap所以通过key，value的形式放值和取值。
     *   memcachedClient提供了add方法进行放值，add方法需要传递三个参数String var1, int var2, Object var3
     *   分别表示：var1：key;  var2:缓存的时间； var3:key对应的值
     *   对外提供put方法往memcache里面放值:
     */
    public boolean put(String key, Integer time, String value) {
        try {
            boolean add = memcachedClient.add(key, time, value);
            return add;
        } catch (TimeoutException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (MemcachedException e) {
            e.printStackTrace();
        }
        return false;
    }

    /*
     *如果把时间写成死的数据:1天，就不需要传时间进来
     * memcache的缓存时间是以秒为单位,默认缓存好像是一个月。
     */
    public boolean put(String key , String value) {
        try {
            boolean add = memcachedClient.add(key, 1*24*60, value);
            return add;
        } catch (TimeoutException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (MemcachedException e) {
            e.printStackTrace();
        }
        return false;
    }

    /*
     * 对外提供取值的get方法
     */
    public String get(String key){
        try {
            String value = (String)memcachedClient.get(key);
            return value;
        } catch (TimeoutException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (MemcachedException e) {
            e.printStackTrace();
        }
        return null;
    }

    //对外提供清除所有缓存的方法：
    public void flushAll(){
        try {
            memcachedClient.flushAll();
        } catch (TimeoutException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (MemcachedException e) {
            e.printStackTrace();
        }
    }

}
