memcached使用

application.properties 

#memcached settings

memcached.url=192.168.1.53:11211

spring配置

<bean id="memcachedClientFactoryBean" class="net.spy.memcached.spring.MemcachedClientFactoryBean">
<property name="servers" value="${memcached.url}" />
<property name="protocol" value="TEXT" />
<property name="locatorType" value="CONSISTENT" />
<property name="opTimeout" value="1000" />
</bean>

<bean id="spyMemcachedClient" class="com.creditcities.framework.cache.SpyMemcachedClient">
<property name="memcachedClient" ref="memcachedClientFactoryBean"/>
</bean>

客户端使用

放入缓存

@PostConstruct
public void afterPropertiesSet() throws Exception {
List<String> typeList =dao.getAllCoreDictionary() ;
for(String c:typeList){
spyMemcachedClient.safeDelete("dictionary_loan_"+c);
Map<String,String> map =getDictionaryByType(c);
if(!map.isEmpty()){
if (logger.isInfoEnabled()) {
logger.info("type:" + c + "-------->map:" + map.toString());
}
spyMemcachedClient.safeSet("dictionary_loan_"+c,map , 1800);
}

}
}

从缓存中取出

@Autowired
    private SpyMemcachedClient spyMemcachedClient;

public User getUserFromCacheByUserId(Long userId) {
User retUser = null;
Object obj = spyMemcachedClient.get(CoreConstants.USER_CACHE_FLAG.concat(String.valueOf(userId)));
if (obj != null && obj instanceof User) {
retUser = (User) obj;
} else {//通过服务方式获取用户信息
logger.info("Not found user from cache in crm system,userId:"+userId);
retUser = getUserFromServiceByUserId(userId);
}
return retUser;
}
