# aiwiown-spring-cache

#### 介绍
aiwiown-cache 缓存框架
    支持本地ehcache缓存,redis缓存 开箱即用!
#### 使用说明

1. 导入依赖
    maven
    ```
             <dependency>
                 <groupId>com.aiwiown</groupId>
                 <artifactId>aiwiown-spring-cache</artifactId>
                 <version>1.0.2-2.0.1</version>
             </dependency>

    ```
2. 添加配置文件
    ```
    aiwiown:
      cache:
        # 缓存仓库 local(本地ehcache),remote(远程redis),local_remote
        store: local_remote
        # 项目名称
        prod-name: demo
      # 远程缓存
      redis:
        # redis密码
        password: rds731wanda
        # redis host
        node: "10.1.64.79:9101,10.1.64.79:9102,10.1.64.79:9103,10.1.64.79:9104,10.1.64.79:9105,10.1.64.79:9106"
        # redis 库,集群环境配置无效
        database: 1
      # 本地缓存
      ehcache:
        # 缓存存放目录
        disk-path: D://ehcache/data
        store-cfg: ehcache.cfg
     ```
3. 本地缓存配置
    ```    
    新增ehcache.cfg 配置文件
      新增本地缓存配置信息
        aiwiown:
          ehcache:
            store:
              PUB_01:
                maxEntriesLocalHeap: 10000
                eternal: false
                diskSpoolBufferSizeMB: 30
                maxEntriesLocalDisk: 10000000
                diskExpiryThreadIntervalSeconds: 120
                memoryStoreEvictionPolicy: LRU
                persistence:
                  strategy: localTempSwap
              PUB:
                maxEntriesLocalHeap: 10000
                eternal: false
                diskSpoolBufferSizeMB: 30
                maxEntriesLocalDisk: 10000000
                diskExpiryThreadIntervalSeconds: 120
                memoryStoreEvictionPolicy: LRU
                persistence:
                  strategy: localTempSwap
 
    ```    
3. 启动类添加启用缓存注解
    ```
    @EnableAiwiownCache
    ```
4. 具体缓存注解

|  注解   | 描述  |
|  ----  | ----  |
| @EnableAiwiownCache| 开启缓存|
| @AiwiownCache  | 指定方法添加注解缓存返回值 |
| @AiwiownCacheKey  | 指定缓存KEY |

5. @AiwiownCache
        
    ```
    key         缓存前缀key
    storeName   缓存空间
    store       缓存存储空间 本地,远程
    expire      缓存过期时间(单位s), -1删除缓存, 0缓存不过期, >0 过期时间
    ```

6. @AiwiownCacheKey
    ```
    value   缓存具体key
        对象使用"#对象.属性"取值, 不支持拼接字符串
    ```

7. 示例代码
    
    eg1:
    一般缓存key
    ```$xslt
            @Override
            @AiwiownCache(store = CacheStore.remote,key = "cache0")
            public String cache0(@AiwiownCacheKey String cache) {
                System.out.println("=======================");
                return cache;
            }
    ```
    
    eg2:
    设置过期时间
    ```$xslt
        @Override
        @AiwiownCache(store = CacheStore.remote,key = "cache1",expire = 60)
        public String cache1(@AiwiownCacheKey String cache) {
            System.out.println("=======================");
            return cache;
        }
    ```
    
    eg3:
    根据对象属性值作为缓存key
    ```$xslt
        @Override
        @AiwiownCache(store = CacheStore.remote,key = "cache-user",expire = 60000)
        public User cacheUser1(@AiwiownCacheKey("#user.id")User user) {
            System.out.println(user.toString());
            return user;
        }
    ```
    
    eg4:
    删除缓存
    ```$xslt
            @Override
            @AiwiownCache(store = CacheStore.remote,key = "cache0",expire = -1)
            public void delete(@AiwiownCacheKey String cache) {
                System.out.println("==========删除缓存=============");
            }
    ```
