使用代码：
``` java
CacheChannel cc=CacheChannel.getInstance();
cc.set("jobell", "hello", "nihaoya");
cc.evict("jobell", "hello");
while(true){
	Object value=cc.get("jobell", "hello");
	if(value==null){
		System.out.println("==============="+value);
	}else{
		System.out.println("==============="+value);
	}
}
```
