首先导入需要的依赖：

 <dependency><groupId>com.github.ben-manes.caffeine</groupId><artifactId>caffeine</artifactId></dependency>

然后是配置文件：

@Configuration
@EnableCaching
@Slf4j
public class CaffeineCacheConfig {/*** CacheManager实现类* @return*/@Bean("cacheManager")public CacheManager cacheManager() {SimpleCacheManager cacheManager = new SimpleCacheManager();// 缓存集合ArrayList<CaffeineCache> caches = new ArrayList<>();// 对缓存key属性做设置caches.add(new CaffeineCache("users-cache",Caffeine.newBuilder()// 指定Key下的最大缓存数据量.maximumSize(1000)// 最后一次访问之后 120秒 过期.expireAfterAccess(120, TimeUnit.SECONDS).build()));cacheManager.setCaches(caches);return cacheManager;}}

最后集成到controller层：

// 修改的情况
@CacheEvict(cacheNames = "users-cache", allEntries = true)@PostMappingpublic ResponseResult save(@Validated(InsertValidationGroup.class)@RequestBody UserDTO userDTO) {int save = userService.save(userDTO);if (save == 1) {return ResponseResult.success("新增成功！");} else {return ResponseResult.failure(ErrorCodeEnum.INSERT_FAILURE);}}// 查询的情况
@Cacheable(cacheNames = "users-cache")@GetMappingpublic ResponseResult<PageResult> query(）{
.......................省略}
