SpringBoot整合ehcache
ehcache 属于jvm内置缓存
1 添加依赖
<!--开启 cache 缓存 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-cache</artifactId> </dependency> <!-- ehcache缓存 --> <dependency> <groupId>net.sf.ehcache</groupId> <artifactId>ehcache</artifactId> <version>2.9.1</version><!--$NO-MVN-MAN-VER$ --> </dependency>
2 ehcache配置文件
<?xml version="1.0" encoding="UTF-8"?> <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"> <!-- 磁盘的缓存位置--> <diskStore path="java.io.tmpdir" /> <!-- 默认缓存 --> <defaultCache maxElementsInMemory="1000" eternal="true" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" diskSpoolBufferSizeMB="30" maxElementsOnDisk="10000000" diskPersistent="true" diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU"> </defaultCache> <!-- demo缓存 --> <cache name="userCache" maxElementsInMemory="1000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" diskSpoolBufferSizeMB="30" maxElementsOnDisk="10000000" diskPersistent="false" diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU"> </cache> </ehcache>
3 使用ehcache
@MapperScan(basePackages = { "com.irish.mapper" }) @EnableCaching @SpringBootApplication public class App { public static void main(String[] args) { SpringApplication.run(App.class, args); } }
@CacheConfig(cacheNames = "userCache") @Service public class UserService { @Autowired private UserMapper userMapper; @Cacheable public List<Users> getUser(Long id) { return userMapper.getUser(id); } }
