jedis2.8.0的进一步封装:
1.序列化存储对象
2.结合spring,创建redis连接池
3.提供了基础的单个实体操作,有序list操作和一对多关系list的操作,对list提供了分页的封装
4.封装了简单的逻辑(如:重建缓存的场景,排序规则,具体方法需要重写~)
具体使用的时候,只需要继承符合你的业务的类(ICacheT,ICachtList,ICacheRelated),并重写下排序,重建时需要的具体数据等方法就可以啦
(1).单个缓存(ICacheT)
public class CachePerson extends CacheTBase<Integer,Person> { @Override protected Person rebuild(Integer tkey) { return null; } }
使用时:
Person p = new Person(); cachePerson.deleteByKey(Person.class,1,2); cachePerson.get(Person.class, 1); cachePerson.delete(p); cachePerson.set(p);
(2).list缓存(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(); } }
使用时:
//批量list添加 list.addTioList(cityList); //一个或多个添加 list.addToList(city1,city2); //通过key删除 list.removeFromListByKey(City.class,"1","2","3","4","5"); //一个或多个删除 list.removeFromList(city1,city2); //批量list删除 list.removeFromList(cityList); //查找list List<City> cityList = list.getList(City.class, true); //查找带分页的list List<City> cityList = list.getListPage(City.class, page, true); //清空list list.clearList();
(3).一对多关系(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; } }
使用时:
//添加 list.addRelated(person, "qiang"); //批量list添加方法 list.addRelateds("qiang", personList); //添加一个或多个 list.addRelateds("qiang",p1,p2,p3,p4,p5); //批量删除关系 list.removeRelated("qiang", personList); //删除一个或多个关系 list.removeRelated("qiang", p1,p2,p3,p4,p5); //根据id删除 list.removeFromListByKey("qiang", Person.class, "2","3"); //获取list,desc=true 为倒序(score 越大,排序越靠前~) list.getRelatedList("qiang", desc) //获取带分页的list,desc=true 为倒序 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> <!--缓存基本操作 --> <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> <!-- 单个--> <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> <!-- 一对多--> <bean id="icacheRelated" class="com.cjdz.test.catchdata.impl.CacheRelatedBase" abstract="true"> <property name="cache" ref="cache"></property> </bean> <!-- 业务--> <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.连接池:
<?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" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd" default-lazy-init="true"> <description>Jedis Configuration</description> <!-- 加载配置属性文件 --> <context:property-placeholder ignore-unresolvable="true" location="classpath:redis.properties" /> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxIdle" value="300" /> <!-- 最大能够保持idel状态的对象数 --> <property name="maxTotal" value="60000" /> <!-- 最大分配的对象数 --> <property name="testOnBorrow" value="true" /> <!-- 当调用borrow Object方法时,是否进行有效性检查 --> </bean> <bean id="jedisPool" class="redis.clients.jedis.JedisPool"> <constructor-arg index="0" ref="jedisPoolConfig" /> <constructor-arg index="1" value="${redis.host}" /> <constructor-arg index="2" value="${redis.port}" type="int" /> <constructor-arg index="3" value="${redis.timeout}" type="int" /> <constructor-arg index="4" value="${redis.auth}"/> </bean> </beans>
最后在RedisDesktop看到的大概是这样式滴:
这个是随便写的一个小东东,类似于helper吧,在使用时,既能规范开发时对缓存的操作,不至于最后缓存都乱掉,也能方便维护缓存。
有很多的局限性,写的时候,对象在redis中存储时,直接用了(对象类名:id) 的方式作为key,而list和related的key则交给开发者重写。之后慢慢改进吧 :)

希望大神提一些意见~~,我来改进改进...
