jedis2.8.0的進一步封裝:
1.序列化存儲對象
2.結合spring,創建redis連接池
3.提供了基礎的單個實體操作,有序list操作和一對多關系list的操作,對list提供了分頁的封裝
4.封裝了簡單的邏輯(如:重建緩存的場景,排序規則,具體方法需要重寫~)
具體使用的時候,只需要繼承符合你的業務的類(ICacheT,ICachtList,ICacheRelated),並重寫下排序,重建時需要的具體數據等方法就可以啦
(1).單個緩存(ICacheT)
public class CachePerson extends CacheTBase<Integer,Person> { @Override protected Person rebuild(Integer tkey) { return null; } }
使用時:
Person p = new Person(); cachePerson.deleteByKey(Person.class,1,2); cachePerson.get(Person.class, 1); cachePerson.delete(p); cachePerson.set(p);
(2).list緩存(ICachtList)
public class CacheCityList extends CacheListBase<City>{ @Override protected String getKey() { return "common:city"; } @Override protected List<City> rebuildList() { return null; } @Override protected List<City> rebuildPageList(Page page) { return null; } @Override protected Double score(City item) { return (double)item.getId(); } }
使用時:
//批量list添加 list.addTioList(cityList); //一個或多個添加 list.addToList(city1,city2); //通過key刪除 list.removeFromListByKey(City.class,"1","2","3","4","5"); //一個或多個刪除 list.removeFromList(city1,city2); //批量list刪除 list.removeFromList(cityList); //查找list List<City> cityList = list.getList(City.class, true); //查找帶分頁的list List<City> cityList = list.getListPage(City.class, page, true); //清空list list.clearList();
(3).一對多關系(ICacheRelated)
public class CacheUserPersonList extends CacheRelatedBase<Person>{ @Override protected String getKey(String mainkey) { return null; } @Override protected List<Person> rebuildList(String mainkey) { return null; } @Override protected List<Person> rebuildPageList(String mainkey, Page page) { return null; } @Override protected double score(Person item) { return 0; } }
使用時:
//添加 list.addRelated(person, "qiang"); //批量list添加方法 list.addRelateds("qiang", personList); //添加一個或多個 list.addRelateds("qiang",p1,p2,p3,p4,p5); //批量刪除關系 list.removeRelated("qiang", personList); //刪除一個或多個關系 list.removeRelated("qiang", p1,p2,p3,p4,p5); //根據id刪除 list.removeFromListByKey("qiang", Person.class, "2","3"); //獲取list,desc=true 為倒序(score 越大,排序越靠前~) list.getRelatedList("qiang", desc) //獲取帶分頁的list,desc=true 為倒序 list.getRelatedListPage("qiang", page, desc); //清空 list.clearList("qiang");
spring固定配置:
1.注入:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!--序列化 --> <bean id="iserializer" class="com.cjdz.test.cache.redis.JsonSerializer"></bean> <!--緩存基本操作 --> <bean id="redisCache" class="com.cjdz.test.cache.redis.RedisCache"> <property name="iserializer" ref="iserializer"></property> </bean> <bean id="cache" class="com.cjdz.test.cache.redis.RedisCache"></bean> <!-- 單個--> <bean id="icacheT" class="com.cjdz.test.catchdata.impl.CacheTBase" abstract="true"> <property name="cache" ref="cache"></property> </bean> <!-- list--> <bean id="icacheList" class="com.cjdz.test.catchdata.impl.CacheListBase" abstract="true"> <property name="cache" ref="cache"></property> </bean> <!-- 一對多--> <bean id="icacheRelated" class="com.cjdz.test.catchdata.impl.CacheRelatedBase" abstract="true"> <property name="cache" ref="cache"></property> </bean> <!-- 業務--> <bean id="cacheCity" class="com.cjdz.test.catchdata.test.CacheCity" parent="icacheT"></bean> <bean id="cachePerson" class="com.cjdz.test.catchdata.test.CachePerson" parent="icacheT"></bean> <bean id="cacheCityList" class="com.cjdz.test.catchdata.test.CacheCityList" parent="icacheList"></bean> <bean id="cacheUserPersonList" class="com.cjdz.test.catchdata.test.CacheUserPersonList" parent="icacheRelated"></bean> </beans>
2.連接池:

最后在RedisDesktop看到的大概是這樣式滴:
這個是隨便寫的一個小東東,類似於helper吧,在使用時,既能規范開發時對緩存的操作,不至於最后緩存都亂掉,也能方便維護緩存。
有很多的局限性,寫的時候,對象在redis中存儲時,直接用了(對象類名:id) 的方式作為key,而list和related的key則交給開發者重寫。之后慢慢改進吧 :)

希望大神提一些意見~~,我來改進改進...
