springboot 整合 ehcache
Spring Boot中整合Ehcache
添加Ehcache依赖:
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId> --根据需要选择版本。
<version>2.10.6</version>
</dependency>
配置Ehcache
Spring Boot项目的application.properties文件中添加以下配置:
# Ehcache配置
ehcache.diskStorePath=target/ehcache
ehcache.maxBytesLocalHeap=100M
ehcache.maxBytesLocalDisk=500M
ehcache.eternal=false
ehcache.timeToIdleSeconds=120
ehcache.timeToLiveSeconds=120
ehcache.overflowToDisk=true
创建EhcacheManagerBean
Spring Boot项目中创建一个名为EhcacheManagerBean的类,并实现以下内容:
import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.config.CacheConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Lazy;
@Configuration
public class EhcacheConfiguration {
@Bean
@Lazy(false)
public CacheManager cacheManager() {
CacheManager cacheManager = new CacheManager();
Cache configurationCache = new Cache(new CacheConfiguration("configurationCache", 10000));
configurationCache.setDiskStorePath("target/ehcache");
cacheManager.addCache(configurationCache);
return cacheManager;
}
}
创建“configurationCache”的Ehcache缓存,并设置缓存配置。
使用Ehcache缓存注解
要在Spring Boot中使用Ehcache缓存注解,添加@EnableCaching注解,并在需要缓存的方法上添加@Cacheable、@CachePut或@CacheEvict注解。例如:
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;
@Service
@EnableCaching
public class MyService {
@Cacheable(value = "configurationCache")
public String getConfigurationValue(String key) {
// 从数据库或其他源获取配置值并返回缓存中相应的值。
}
}
