2. 配置cacheConfiguration类

package com.idcos.automate.biz.common.cache;import org.springframework.cache.annotation.EnableCaching;import org.springframework.cache.ehcache.EhCacheCacheManager;import org.springframework.cache.ehcache.EhCacheManagerFactoryBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.core.io.ClassPathResource;@Configuration@EnableCachingpublic class EhcacheConfiguration {    @Bean(name = "ehCacheCacheManager")    public EhCacheCacheManager ehCacheCacheManager(EhCacheManagerFactoryBean bean) {        return new EhCacheCacheManager(bean.getObject());    }    @Bean    public EhCacheManagerFactoryBean ehCacheManagerFactoryBean() {        EhCacheManagerFactoryBean cacheManagerFactoryBean = new EhCacheManagerFactoryBean();        cacheManagerFactoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));        cacheManagerFactoryBean.setShared(true);        return cacheManagerFactoryBean;    }}

3. 配置xml

<?xml version="1.0" encoding="UTF-8"?><ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"         updateCheck="false">    <diskStore path="java.io.tmpdir/Tmp_EhCache"/>    <defaultCache eternal="false" maxElementsInMemory="1000" overflowToDisk="false" diskPersistent="false"                  timeToIdleSeconds="0" timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU"/>    <cache name="random"           eternal="false"           maxElementsInMemory="100"           overflowToDisk="false"           diskPersistent="false"           timeToIdleSeconds="0"           timeToLiveSeconds="300"           memoryStoreEvictionPolicy="LRU"/></ehcache>

4. 配置cache实现类

package com.idcos.cloud.biz.common.util;import java.util.List;import java.util.UUID;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.cache.annotation.CacheConfig;import org.springframework.cache.annotation.Cacheable;import org.springframework.stereotype.Service;import com.idcos.cloud.core.dal.domain.settings.SettingPlatformDict;import com.idcos.cloud.core.dal.repository.settings.SettingPlatformDictRepository;@Service@CacheConfigpublic class CacheUtil {    @Cacheable("random")    public String getRandomString() {        return UUID.randomUUID().toString();    }}

package pkg_manager;import org.junit.Assert;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.SpringApplicationConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.idcos.PkgManager;import com.idcos.cloud.biz.common.util.CacheUtil;@RunWith(SpringJUnit4ClassRunner.class)@SpringApplicationConfiguration(classes = PkgManager.class)public class PkgTest {    @Autowired    private CacheUtil CacheUtil;    @Test    public void test() {        testCache();    }    public void testCache() {        Assert.assertNotNull(CacheUtil);        Assert.assertEquals(CacheUtil.getRandomString(), CacheUtil.getRandomString());        System.out.println(CacheUtil.getRandomString());        System.out.println(CacheUtil.getRandomString());    }}
