4.0. 增加spymemcached依赖

net.spyspymemcached2.12.0

4.1. 配置memcached的ip地址

分别在dev,test,idc,prod的app-config.properties文件下添加memcached的ip地址：

dev，test：memcache_ip=192.168.1.10:11211

idc：memcache_ip=172.16.4.10:11211

prod：memcache_ip=172.16.0.10:11211

4.2. 配置memcached实例：

app-cached.xml文件增加：

4.3. 新增类SpringContextHolder

import java.util.Map;

import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;

/** *  * 以静态变量保存Spring ApplicationContext, 可在任何代码任何地方任何时候中取出ApplicaitonContext. **/

public class SpringContextHolder implements ApplicationContextAware {

private static ApplicationContext applicationContext;

/** *  * 实现ApplicationContextAware接口的context注入函数, 将其存入静态变量. */

public void setApplicationContext(ApplicationContext applicationContext) {

SpringContextHolder.applicationContext = applicationContext;

}

/** *  * 取得存储在静态变量中的ApplicationContext. */

public static ApplicationContext getApplicationContext() {

checkApplicationContext();

return applicationContext;

}

/** *  * 从静态变量ApplicationContext中取得Bean, 自动转型为所赋值对象的类型. */

@SuppressWarnings("unchecked") public static T getBean(String name) {

checkApplicationContext();

return (T) applicationContext.getBean(name);

}

/** *  * 从静态变量ApplicationContext中取得Bean, 自动转型为所赋值对象的类型. *  * 如果有多个Bean符合Class, 取出第一个. */

@SuppressWarnings("unchecked") public static T getBean(Class clazz) {

checkApplicationContext();

Map beanMaps = applicationContext.getBeansOfType(clazz);

if (beanMaps != null && !beanMaps.isEmpty()) {

return (T) beanMaps.values().iterator().next();

} else {

return null;

}

}

private static void checkApplicationContext() {

if (applicationContext == null) {

throw new IllegalStateException("applicaitonContext未注入,请在applicationContext.xml中定义SpringContextHolder");

}

}

}

4.4.增加MemcacheUtil

import com.test.bean.SpringContextHolder;import net.spy.memcached.MemcachedClient;

public class MemcacheUtil {    public static MemcachedClient getMemCachedClient() {        return SpringContextHolder.getBean("memcachedClient");}}

4.5 测试代码

public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext( "classpath:spring-memcached-spy.xml"); MemcachedClient client=MemcacheUtil.getMemCachedClient();  //MemcachedClient client =(MemcachedClient)context.getBean("memcachedClient"); Object obj=client.get("glt7hpcdi1ggo03l9qknu8a755");  System.out.println(obj); }
