背景：最近项目组在开发本地缓存，其中用到了redis和ehcache，但是在使用注解过程中发现两者会出现冲突，这里给出解决两者冲突的具体方案。
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缓存配置管理文件</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：
package org.szfs.basic.middle.cache;import java.lang.reflect.Method; import java.util.ArrayList; import java.util.Collection;import org.springframework.beans.factory.annotation.Autowired; import org.springframework.cache.Cache; import org.springframework.cache.CacheManager; import org.springframework.cache.annotation.CachingConfigurerSupport; import org.springframework.cache.annotation.EnableCaching; import org.springframework.cache.ehcache.EhCacheCacheManager; import org.springframework.cache.interceptor.KeyGenerator; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.cache.RedisCacheManager;/*** 缓存集成配置类<p>* * 该类通过向spring提供统一的{@link CacheManager}以达到集成不同缓存中间件的目的，v0.1包括redis与ehcache<br>* 该类重写了{@link CachingConfigurerSupport#cacheManager()}和{@link CachingConfigurerSupport#keyGenerator()}的方法* * @author 51* @version $Id: SzfsCacheConfig.java, v 0.1 2018年2月5日 下午6:45:44 51 Exp $* * @see org.springframework.cache.annotation.CachingConfigurerSupport*/ @Configuration @EnableCaching public class SzfsCacheConfig extends CachingConfigurerSupport {/*** redis缓存前缀<p>* 用于通过缓存名前缀识别缓存中间件*/private static final String REDIS_PREFIX = "redis-";@Autowired(required = false)private volatile RedisCacheManager redisCacheManager;@Autowired(required = false)private volatile EhCacheCacheManager ehCacheCacheManager;public SzfsCacheConfig() {super();}/*** 构建CacheManager的实例szfsCacheManager<p>* * szfsCacheManager通过缓存名称<b>前缀</b>来识别缓存类型：* <ul>* <li>"redis-": redis cache</li>* <li> others : ehcache cache</li>* </ul>* 该实例是spring操作缓存所必须的，且需要保证唯一，这意味着，如果还需要Spring集成其它缓存中间件，仍然需要集成到szfsCacheManager<br>* * @see org.springframework.cache.annotation.CachingConfigurerSupport#cacheManager()*/@Bean("szfsCacheManager")@Overridepublic CacheManager cacheManager() {return new CacheManager() {@Overridepublic Collection<String> getCacheNames() {Collection<String> cacheNames = new ArrayList<String>();if (redisCacheManager != null) {cacheNames.addAll(redisCacheManager.getCacheNames());}if (ehCacheCacheManager != null) {cacheNames.addAll(ehCacheCacheManager.getCacheNames());}return cacheNames;}@Overridepublic Cache getCache(String name) {if (name.startsWith(REDIS_PREFIX)) {return redisCacheManager == null ? null : redisCacheManager.getCache(name);} else {return ehCacheCacheManager == null ? null : ehCacheCacheManager.getCache(name);}}};}/*** 构建默认的键生成器* @see org.springframework.cache.annotation.CachingConfigurerSupport#keyGenerator()*/@Bean@Overridepublic KeyGenerator keyGenerator() {return new KeyGenerator() {@Overridepublic Object generate(Object target, Method method, Object... params) {StringBuilder keyStrBuilder = new StringBuilder();keyStrBuilder.append(target.getClass().getName());keyStrBuilder.append(method.getName());for (Object _param : params) {keyStrBuilder.append(_param.toString());}return keyStrBuilder.toString();}};}public RedisCacheManager getRedisCacheManager() {return redisCacheManager;}public void setRedisCacheManager(RedisCacheManager redisCacheManager) {this.redisCacheManager = redisCacheManager;}public EhCacheCacheManager getEhCacheCacheManager() {return ehCacheCacheManager;}public void setEhCacheCacheManager(EhCacheCacheManager ehCacheCacheManager) {this.ehCacheCacheManager = ehCacheCacheManager;}}
