为什么Spring不缓存方法？

Question

我是Spring缓存新手，并且一直在使用ASCII Table。有人可以帮我弄清楚为什么这个方法没有缓存？

修改

经过大量阅读后，我的理论是我需要告诉Spring将事物缓存在缓存文件中，我目前没有

import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachePut;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.cache.annotation.EnableCaching;

//http://www.ehcache.org/blog/2016/05/18/ehcache3_jsr107_spring.html
//https://github.com/gibsong/ehcache-jsr107-spring

@Path("/helloservice")
@EnableCaching
public class HelloService{

    @GET
    @Path("/cache")
    @Produces({"text/plain"})
    //@CachePut(cacheNames=cacheName, key="testCache")
    @Cacheable(cacheName)
    public String testCache(){
        String start=LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));
        try {
            long time = 3000L;
            Thread.sleep(time);
        } catch (InterruptedException e) {
            throw new IllegalStateException(e);
        }
        String end=LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));

        return "started: "+start+"\nended: "+end;
    }
}
