自定义注解&Spring AOP实现为原程序加入Redi

应用场景##
- 数据访问采用ORM方式（Hibernate） 直接访问数据库，在访问量小、并发性小、数据量小时，可正常访问，反之则服务响应能力低。
目标&要解决的问题##
- 自定义注解&Spring AOP为项目加入Redis缓存依赖提高应用程序的响应能力(可重用)
项目扩充承接于http://www.jianshu.com/p/25039d901ac2
难点##
设置缓存的失效策略，缓存数据的Struct选取，切面(Aspect)的编写
方法&扩充步骤##
1.扩充build.gradle 脚本文件
//https://mvnrepository.com/artifact/org.springframework.data/spring-data-redis 项目添加redis支持
compile group: 'org.springframework.data', name: 'spring-data-redis', version: '1.4.1.RELEASE'
// https://mvnrepository.com/artifact/redis.clients/jedis redis 基于java的Redis客户端调用实现
compile group: 'redis.clients', name: 'jedis', version: '2.6.1'
// https://mvnrepository.com/artifact/com.alibaba/fastjson
// 采用阿里巴巴fastjson 进行对象&json字符串的序列化与反序列化
compile group: 'com.alibaba', name: 'fastjson', version: '1.2.21'
2.扩充Spring 配置文件，添加Redis相关Java Bean 到Ioc容器中
为了符合开闭原则，重新创建Spring 配置文件 spring-redis.xml
<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxIdle" value="100" />
<!-- <property name="max" value="${redis.maxActive}" />
<property name="maxWait" value="${redis.maxWait}" />-->
<property name="testOnBorrow" value="true" />
</bean>
<bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
p:host-name="127.0.0.1" p:port="6379" p:password="ls" p:pool-config-ref="jedisPoolConfig"/>
<bean id="redisTemplateForString" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="connectionFactory" />
</bean>
</beans>
3.自定义两个注解
- RedisCahe: 标识缓存 注解
- RedisEvit: 标识缓存清除 注解
代码如下：
RedisCahe.java
package com.fxmms.common.rediscache.redisannotation;
import java.lang.annotation.*;
/**
* Created by mark on 16/11/29.
* @usage 缓存注解类
*/
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
@Documented
public @interface RedisCache {
Class type();//被代理类的全类名，在之后会做为redis hash 的key
}
RedisEvit.java
package com.fxmms.common.rediscache.redisannotation;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
/**
* Created by mark on 16/11/29.
* @usage 清除过期缓存注解，放置于update delete insert 类型逻辑之上
*/
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface RedisEvict {
Class type();
}

注意：
- 上述程序中为非查询方法上加上了 @RedisEvict注解，表示删除旧的缓存。
- 上述程序中为查询方法上加上了 @RedisCache注解，表示为查询业务逻辑应用缓存，应用逻辑为：项目中缓存数据的Struct为Hash，每张表对应的实体类使用一个名为Key的Hash结构来存储数据，当访问的key 存在时，直接从缓存中取出数据，不存在时第一步先从数据库中查询数据，再生成key，并生成对应的filed与value。
