Spring boot配置cache

spring boot配置缓存

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();
}
}

5. 测试

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());
}
}
