Java序列化和反序列化操作

fastjson可以实现java的序列化和反序列化操作，这里使用serialize的方法重新写序列化方法改写成JSON格式，方便通信与读写。
首先定义FastJsonRedisSerializer.java内容

public class FastJsonRedisSerializer<T> implements RedisSerializer<T>
{public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");private Class<T> clazz;static{//静态变量、静态方法、静态常量统称为类的静态成员，归整个类所有//不属于某个单一的对象//ParserConfig.getGlobalInstance().setAutoTypeSupport(true);//全局变量设置为这个}public FastJsonRedisSerializer(Class<T> clazz){super();this.clazz = clazz;}//重新写序列化方法，改写成JSON格式，方便通信与读写@Overridepublic byte[] serialize(T t) throws SerializationException{if (t == null){return new byte[0];}return JSON.toJSONString(t, SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET);/***toJSONString(t,SerializerFeature.WriteClassName)中WriteClassName:序列化写入类型信息，默认为false普通的JSON文本不知道它是什么类型，比如{"id":12,"name":魏嘉留}传入的JSON文本{"@type":"com.alibaba.demo.Employee","id":12,"name":魏嘉留}***/}@Overridepublic T deserialize(byte[] bytes) throws SerializationException{if (bytes == null || bytes.length <= 0){return null;}String str = new String(bytes, DEFAULT_CHARSET);//DEFAULT_CHARSET为上面定义的UTF-8//System.out.println("clazz = "+clazz);return JSON.parseObject(str, clazz);}

然后调用Json开始进行序列化以及反序列化操作：

public class Helloworld {public static void main(String[] args) {FastJsonRedisSerializer a = new FastJsonRedisSerializer(Integer.class);System.out.println(a.serialize(new Integer(5)));System.out.println(a.deserialize(a.serialize(new Integer(5))));}
}
