实现类

import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;
@Service
public class CacheServiceImpl implements CacheService{
    @Cacheable(value="departCache",key="#i")
    public String findUser(int i) {
        StringBuffer sb=new StringBuffer();
        int j=0;
        for(;j<i;j++){
            sb.append("hello"+i);
        }
        return sb.toString();

    }

}

@RunWith(SpringJUnit4ClassRunner.class)

public class TestCache {   

   @Resource
   CacheServiceImpl cacheServiceImpl;

    @Test
    public void testSend() {
     System.out.println(System.currentTimeMillis());
       cacheServiceImpl.findUser(1000);
       System.out.println(System.currentTimeMillis());

       System.out.println(System.currentTimeMillis());
       cacheServiceImpl.findUser(1000);
       System.out.println(System.currentTimeMillis());

    }
