redis使⽤fastjson序列化和反序列化redis
class FastJson2JsonRedisSerializer<T>implements RedisSerializer<T>{
private ObjectMapper objectMapper =new ObjectMapper();
public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");
private Class<T> clazz;
static{
}
public FastJson2JsonRedisSerializer(Class<T> clazz){
super();
fastjson怎么用
this.clazz = clazz;
}
public byte[]serialize(T t)throws SerializationException {
if(t == null){
return new byte[0];
}
JSONString(t, SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET);
}
public T deserialize(byte[] bytes)throws SerializationException {
if(bytes == null || bytes.length <=0){
return null;
}
String str =new String(bytes, DEFAULT_CHARSET);
return JSON.parseObject(str, clazz);
}
public void setObjectMapper(ObjectMapper objectMapper){
this.objectMapper = objectMapper;
}
protected JavaType getJavaType(Class<?> clazz){
return TypeFactory.defaultInstance().constructType(clazz);
}
}
