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();
         }
     }
