列化工具-fastjson-序列化和反序列化用法

一、环境依赖：

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>fastjson</artifactId>
  <version>1.2.58</version>
</dependency>

二、序列化&反序列化：

public class FastjasonSerializer implements IGsonSerializer {
@Override
public <T> byte[] serialize(T obj) {
return JSONObject.toJSONString(obj).getBytes();
}
@Override
public <T> T deserialize(byte[] data, Class<T> clazz) {
return (T)JSONObject.parseObject(new String(data),clazz);
}

}


public interface IGsonSerializer {
    <T> byte[] serialize(T obj);
    <T> T deserialize(byte[] data,Class<T> clazz);
}
public class TestMain {
    public static void main(String[] args) {
        Student stu=new Student();
        stu.setName("jason");
        stu.setAge(18);
        IGsonSerializer serializer=new FastjasonSerializer ();
        long t1 = System.nanoTime();
        byte[] serialize = serializer.serialize(stu);
        System.out.println("序列化耗时="+(System.nanoTime()-t1));
        System.out.println("fastjason 序列化长度 result="+serialize.length);
        System.out.println(""+new String(serialize));
        long t3 = System.nanoTime();
        Student stu2=(Student)(Student)serializer.deserialize(serialize,stu.getClass());
        System.out.println("反序列化耗时="+(System.nanoTime()-t3));
    }
}
