配置

@Configuration
@EnableCaching(proxyTargetClass = true)
public class CacheConfig implements CachingConfigurer {

    @Value("#{'${cacheManager.names}'.split(',')}")
    private List cacheManagerNames;

    @Bean
    @Override
    public CacheManager cacheManager() {
        SimpleCacheManager cacheManager = new SimpleCacheManager();
        List list = new ArrayList<>();
        for (String name : cacheManagerNames) {
            list.add(new ConcurrentMapCache(name));
        }
        cacheManager.setCaches(list);
        return cacheManager;
    }

    @Bean
    @Override
    public KeyGenerator keyGenerator() {
        return new DefaultKeyGenerator();
    }
}

使用

    @Cacheable(value = "propConfigCache",key = "#root.method.toString()+#key ",condition = "#key==null or ''.equals(#key.trim())")
    @Override
    public Map get(String key) {
        Map map = new HashMap<>();
        map.put("date", new Date());
        return map;
    }
