项目特点

1.保留原框架的集成，扩展，配置能力

• 集成
  通过依赖对应的cache实现，可自动装载对应配置
• 扩展
  依赖原spring-cache核心能力，保留其扩展能力
• 配置
  原spring配置同样生效，如不使用cache-plus框架能力，原生配置不受影响
  使用cache-plus相关功能，仅更换配置前缀即可

2.对于spring-cache增强

• 支持多cache同时使用
• 支持Redisson实现的CacheManager自动注入
• 支持具体缓存失效时间配置,全局配置及注解均支持
• 支持二级缓存
• 支持强一致事务缓存

1.引入核心依赖

暂时未发到中央仓库(准备中)…

<dependency><groupId>com.ty</groupId><artifactId>ty-framework-cache-starter</artifactId><version>${最新版本}</version>
</dependency>

2.开启多cache配置

application.yml示例：

application:cache:multi-enable: truetype: redis,caffeineredis:cache-names: test1,test2enable-transactions: truestore-type: key_valuecache-null-values: truenull-value-time-to-live: PT20stime-to-live: PT20muse-key-prefix: truekey-prefix: cachecaffeine:cache-names: caffeine-name

2.自选缓存pom依赖

• 如使用redis缓存,按照Spring Boot data Redis官方配置即可,以下为使用Redisson客户端pom:

<dependency><groupId>org.redisson</groupId><artifactId>redisson-spring-boot-starter</artifactId>
</dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

正确配置redis示例

  redis:host: localhostport: 6379timeout: 1200

• 如使用caffeine缓存,添加如下pom:

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

二:使用示例

1.api示例

和常规spring cache一致

@Component
public class test {@AutowiredCacheManager cacheManager;public void cache() {Cache cache = cacheManager.getCache("test1");cache.put("aaa", 123);Integer value = cache.get("aaa", Integer.class);}
}

2.注解示例

和spring cache一致

@Service
@Slf4j
@CacheConfig(cacheNames = CacheNameConstant.CAHCE_NAME)
public class CapitalAccountCacheService {@Autowiredprivate MyCapitalCacheDAO myCapitalDAO;@Autowired@Lazyprivate CapitalAccountCacheService _self;public List<MyCapitalAccount> getAll() {return myCapitalDAO.getAll();}@Cacheable(key = "#id", sync = true)public MyCapitalAccount getById(Long id) {MyCapitalAccount byId = myCapitalDAO.getById(id);log.info("CapitalAccountCacheService getById from db,myCapitalAccount:{}", byId);return byId;}@CachePut(key = "#myCapitalAccount.id", condition = "#result.getId()!=null&&#result.getId()>0")public MyCapitalAccount insert(MyCapitalAccount myCapitalAccount) {log.info("CapitalAccountCacheService insert to db,myCapitalAccount:{}", myCapitalAccount);myCapitalDAO.insert(myCapitalAccount);return myCapitalAccount;}@CachePut(key = "#myCapitalAccount.id", condition = "#result!=null")public MyCapitalAccount update(MyCapitalAccount myCapitalAccount) {log.info("CapitalAccountCacheService update to db,myCapitalAccount:{}", myCapitalAccount);int update = myCapitalDAO.update(myCapitalAccount);if (update > 0) {return myCapitalAccount;}return null;}@CacheEvict(key = "#myCapitalAccount.id")public int delete(MyCapitalAccount myCapitalAccount) {log.info("CapitalAccountCacheService delete to db,myCapitalAccount:{}", myCapitalAccount);return myCapitalDAO.deleteById(myCapitalAccount.getId());}@CacheEvict(allEntries = true)public int deleteAll() {log.info("CapitalAccountCacheService delete All from db");return myCapitalDAO.deleteAll();}
}    

三:配置说明

除了spring-cache提供的缓存类型外,框架提供redis额外两个实现:
REDISSON_2PC,

 REDISSON_LOCAL_MAP 基于redisssonRLocalMap实现的二级缓存CacheManagerREDISSON_2PC 基于redisson实现的支持强一致性事务的缓存CacheManager

1.REDISSON_LOCAL_MAP

Redisson官方宣传的,增加了本地的缓存,性能提升最高45倍,适用于对数据一致性要求不高,但访问量较大,对性能要求极高,甚至连网络请求都成为瓶颈的场景

2.REDISSON_2PC

基于redisson实现的支持强一致性事务的缓存CacheManager,整合mysql事务请求,在RR隔离级别下,通过事务线程绑定方式,在本地增加TreadLocal二级缓存,
保证缓存事务过程的可重复读,在mysql事务提交过程,通过redis事务提交或回滚redis相关操作,保证强一致性
