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/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/cache http://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") @Override public CacheManager cacheManager() { return new CacheManager() { @Override public 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; } @Override public 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 @Override public KeyGenerator keyGenerator() { return new KeyGenerator() { @Override public 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; } }
