背景：最近項目組在開發(fā)本地緩存，其中用到了redis和ehcache，但是在使用注解過程中發(fā)現(xiàn)兩者會出現(xiàn)沖突，這里給出解決兩者沖突的具體方案。

spring-ehcache.xml配置：

<?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:cache="http://www.springframework.org/schema/cache"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/cachehttp://www.springframework.org/schema/cache/spring-cache-4.0.xsd"><description>ehcache緩存配置管理文件</description><bean id="ehCacheManagerFactory"class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"><property name="configLocation" value="classpath:ehcache/ehcache.xml" /></bean><bean id="ehCacheCacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"><property name="cacheManager" ref="ehCacheManagerFactory" /></bean></beans>

整合Ehcache和Redis的cacheManager，并注入容器：
