ehcache配置文件

<?xml version="1.0" encoding="UTF-8"?>
    <ehcache>
        
        <diskStore path="java.io.tmpdir"/>
    
        
        <defaultCache
                maxElementsInMemory="10000"
                eternal="false"
                overflowToDisk="true"
                timeToIdleSeconds="5"
                timeToLiveSeconds="7"
                diskPersistent="false"
                diskExpiryThreadIntervalSeconds="120"/>
    
        
        <cache name="cacheTest"
               maxElementsInMemory="1000"
               eternal="false"
               overflowToDisk="true"

               timeToLiveSeconds="10"/>
        
        
        
        
        
    
        
        
    </ehcache>

使用缓存的service代码

@Service
    public class CacheTestServiceImpl implements CacheTestService {
        @Cacheable(value = "cacheTest")
        @Override
        public String getTime() {
            SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:S");
            return format.format(new Date());
        }
        @CacheEvict(value = "cacheTest")
        @Override
        public String getNewTime() {
            SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:S");
            return "缓存被刷新";
        }
    }

测试类

public class TestMain {
        private static Logger log= LogManager.getLogger(TestMain.class);
        public static void main(String[] args) throws InterruptedException {
            ApplicationContext app=new ClassPathXmlApplicationContext("spring/applicationContext.xml");
            CacheTestService cacheTestService = app.getBean(CacheTestService.class);
            CacheManager cacheManager = app.getBean(CacheManager.class);
            Cache cacheTest = cacheManager.getCache("cacheTest");
            int count=0;
            while (true){
                count++;
                log.debug(cacheTestService.getTime());
                if(count==4||count==8){
    //                cacheTest.flush();
                    cacheTestService.getNewTime();
                }
                Thread.sleep(1000);
            }
        }
    }
