Spring boot配置cache(ehcache)

spring boot配置缓存

第一次配置缓存，记录一下

1. 添加cache依赖

<dependency>
<groupId>net.sf.ehcache</groupId>

<artifactId>ehcache</artifactId>

<version>2.10.1</version>

</dependency>

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
@EnableCaching
public 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
@CacheConfig
public 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());
    }
}

cacheable注解当中的名称要与xml配置的名称一致 
configuration当中的xml名称要与xml的名字一致
