1.新建抽象類,jdk1.8同樣可以建立介面.

public abstract class SerializeTranscoder {
protected static Logger logger = Logger.getLogger(SerializeTranscoder.class);

public abstract byte[] serialize(Object value);//序列化物件為位元組集合

public abstract Object deserialize(byte[] in);//轉換成物件

public void close(Closeable closeable) {
if (closeable != null) {
try {
closeable.close();
} catch (Exception e) {
logger.info("Unable to close " + closeable, e); 
}
}
}
}

2.建立list的實現類

public class ListTranscoder<M extends Serializable> extends SerializeTranscoder {

@SuppressWarnings("unchecked")
public List<M> deserialize(byte[] in) {
List<M> list = new ArrayList<>();
ByteArrayInputStream bis = null;
ObjectInputStream is = null;
try {
if (in != null) {
bis = new ByteArrayInputStream(in);
is = new ObjectInputStream(bis);
while (true) {
M m = (M)is.readObject();
if (m == null) {
break;
}

list.add(m);

}
is.close();
bis.close();
}
} catch (IOException e) {  
   LoggerUtils.error(logger, String.format("Caught IOException decoding %d bytes of data",  
   in == null ? 0 : in.length) + e);  
} catch (ClassNotFoundException e) {  
   LoggerUtils.error(logger, String.format("Caught CNFE decoding %d bytes of data",  
   in == null ? 0 : in.length) + e);  
}  finally {
close(is);
close(bis);
}

return  list;
}



@SuppressWarnings("unchecked")
@Override
public byte[] serialize(Object value) {
if (value == null)
throw new NullPointerException("Can't serialize null");

List<M> values = (List<M>) value;

byte[] results = null;
ByteArrayOutputStream bos = null;
ObjectOutputStream os = null;

try {
bos = new ByteArrayOutputStream();
os = new ObjectOutputStream(bos);
for (M m : values) {
os.writeObject(m);
}

// os.writeObject(null);
os.close();
bos.close();
results = bos.toByteArray();
} catch (IOException e) {
throw new IllegalArgumentException("Non-serializable object", e);
} finally {
close(os);
close(bos);
}

return results;
}
}

3.建立Object物件的類

public class ObjectsTranscoder<M extends Serializable> extends SerializeTranscoder {
@SuppressWarnings("unchecked")
@Override
public byte[] serialize(Object value) {
if (value == null) {  
throw new NullPointerException("Can't serialize null");  
}  
byte[] result = null;  
ByteArrayOutputStream bos = null;  
ObjectOutputStream os = null;  
try {  
bos = new ByteArrayOutputStream();  
os = new ObjectOutputStream(bos);
M m = (M) value;
os.writeObject(m);  
os.close();  
bos.close();  
result = bos.toByteArray();  
} catch (IOException e) {  
throw new IllegalArgumentException("Non-serializable object", e);  
} finally {  
close(os);  
close(bos);  
}  
return result;  
}


@SuppressWarnings("unchecked")
@Override
public M deserialize(byte[] in) {
M result = null;  
ByteArrayInputStream bis = null;  
ObjectInputStream is = null;  
try {  
 if (in != null) {  
 bis = new ByteArrayInputStream(in);  
 is = new ObjectInputStream(bis);  
 result = (M) is.readObject();  
 is.close();  
 bis.close();  
 }  
} catch (IOException e) {  
 LoggerUtils.error(logger, String.format("Caught IOException decoding %d bytes of data",  
 in == null ? 0 : in.length) + e);  
} catch (ClassNotFoundException e) {  
 LoggerUtils.error(logger, String.format("Caught CNFE decoding %d bytes of data",  
 in == null ? 0 : in.length) + e);  
} finally {  
 close(is);  
 close(bis);  
}  
 return result;  
}
}

jedis就可以直接操作list和Object物件.

public void setObjectList(String key,List<M> value,int cacheSeconds){

Jedis jedis=getResource();

if(jedis.exists(key)){

jedis.del(key);

}

ListTranscoder coder=new ListTranscoder();

jedis.set(key.getBytes(),coder.serialize(value));

if(cacheSeconds){//快取時間

jedis.expire(key,cacheSeconds);

}

}
