本文介绍了如何在Spring Boot应用中整合Ehcache，包括添加相关依赖、配置缓存管理类、设置ehcache.xml配置文件，以及实现CacheService和Controller进行缓存操作的示例。通过这些步骤，Ehcache已成功融入到系统中，提供了本地缓存功能。

spring boot整合ehcache

（1）依赖

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.8.3</version>
</dependency>

（2）缓存配置管理类

@Configuration
@EnableCaching
public class CacheConfiguration {

@Bean
public EhCacheManagerFactoryBean ehCacheManagerFactoryBean(){
EhCacheManagerFactoryBean cacheManagerFactoryBean = new EhCacheManagerFactoryBean();
cacheManagerFactoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));
cacheManagerFactoryBean.setShared(true);
return cacheManagerFactoryBean;
}

@Bean
public EhCacheCacheManager ehCacheCacheManager(EhCacheManagerFactoryBean bean){
return new EhCacheCacheManager(bean.getObject());
}

}

（3）ehcache.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="0"
memoryStoreEvictionPolicy="LRU" />

<cache
name="local"
eternal="false"
maxElementsInMemory="1000"
overflowToDisk="false"
diskPersistent="false"
timeToIdleSeconds="0"
timeToLiveSeconds="0"
memoryStoreEvictionPolicy="LRU" />

</ehcache>

（4）CacheService

@Service("cacheService")
public class CacheServiceImpl implements CacheService {

public static final String CACHE_NAME = "local";

@Cacheable(value = CACHE_NAME, key = "'key_'+#id")
public ProductInfo findById(Long id){
return null;
}

@CachePut(value = CACHE_NAME, key = "'key_'+#productInfo.getId()")
public ProductInfo saveProductInfo(ProductInfo productInfo) {
return productInfo;
}

}

（5）写一个Controller测试一下ehcache的整合

@Controller
public class CacheTestController {

@Resource
private CacheService cacheService;

@RequestMapping("/testPutCache")
@ResponseBody
public void testPutCache(ProductInfo productInfo) {
System.out.println(productInfo.getId() + ":" + productInfo.getName());
cacheService.saveProductInfo(productInfo);
}

@RequestMapping("/testGetCache")
@ResponseBody
public ProductInfo testGetCache(Long id) {
ProductInfo productInfo = cacheService.findById(id);
System.out.println(productInfo.getId() + ":" + productInfo.getName());
return productInfo;
}

}

ehcache已经整合进了我们的系统，spring boot

封装好了对ehcache本地缓存进行添加和获取的方法和service
