序列化工具-Gson-序列化和反序列化用法

一、环境依赖：

<dependency>
   <groupId>com.google.code.gson</groupId>
   <artifactId>gson</artifactId>
   <version>2.8.6</version>
</dependency>

二、序列化&反序列化：

public class GsonSerializer implements IGsonSerializer {
    @Override
    public <T> byte[] serialize(T obj) {
        GsonBuilder gsonBuilder = new GsonBuilder();
        gsonBuilder.setPrettyPrinting();
        Gson gson = gsonBuilder.create();
        return gson.toJson(obj).getBytes();
    }
    @Override
    public <T> T deserialize(byte[] data, Class<T> clazz) {
        Gson gson = new Gson();
        return (T)gson.fromJson(new String(data), clazz);
    }
}
public class TestMain {
    public static void main(String[] args) {
        Student stu=new Student();
        stu.setName("jason");
        stu.setAge(18);
        IGsonSerializer serializer=new GsonSerializer();
        long t1 = System.nanoTime();
        byte[] serialize = serializer.serialize(stu);
        System.out.println("序列化耗时="+(System.nanoTime()-t1));
        System.out.println("Gson 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));
    }
}
public interface IGsonSerializer {
    <T> byte[] serialize(T obj);
    <T> T deserialize(byte[] data,Class<T> clazz);
}
