实例化对象：
Student：
public class Teacher implements Serializable{
private static final long serialVersionUID = 1L;
@Protobuf(required = true, order = 1, fieldType = FieldType.STRING)
private String id;
@Protobuf(required = true, order = 2, fieldType = FieldType.STRING)
private String name;
@Protobuf(required = true, order = 3, fieldType = FieldType.INT32)
private int age;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public String toString() {
return "Teacher{" +
"id='" + id + '\'' +
", name='" + name + '\'' +
", age=" + age +
'}';
}
}
Teacher：
public class Student implements Serializable{
private static final long serialVersionUID = 1L;
@Protobuf(required = true, order = 1, fieldType = FieldType.STRING)
private String id;
@Protobuf(required = true, order = 2, fieldType = FieldType.STRING)
private String name;
@Protobuf(required = true, order = 3, fieldType = FieldType.INT32)
private int age;
@Protobuf(required = true, order = 4, fieldType = FieldType.STRING)
private String grade;
@Protobuf(required = true, order = 5, fieldType = FieldType.OBJECT)
private Teacher teacher;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getGrade() {
return grade;
}
public void setGrade(String grade) {
this.grade = grade;
}
public Teacher getTeacher() {
return teacher;
}
public void setTeacher(Teacher teacher) {
this.teacher = teacher;
}
@Override
public String toString() {
return "Student{" +
"id='" + id + '\'' +
", name='" + name + '\'' +
", age=" + age +
", grade='" + grade + '\'' +
", teacher=" + teacher.toString() +
'}';
}
}
序列化实现：
public class SerializableDemo {
//初始化
private final static int SERIALIZABLE_NUM = 10000;
public static void main(String[] args) throws Exception {
System.out.println("初始化数据============================\n" + init().toString() + "\n");
//java原生
excuteWithNative();
//jackson
excuteWithJackSon();
//fastJson
excuteWithFastJson();
//hessian
excuteWithHessian();
//protobuf，baidu公司开发，底层给予protobuf,不用proto文件，通过注解即可实现序列化反序列化
excuteWithProtoBuf();
//kryo
excuteWithKryo();
//主流序列化方式JSON/Hessian(2) /xml/protobuf/kryo/MsgPack/FST/thrift/protostuff/Avro
//更多序列化方式查看网络资料即可
}
private static void excuteWithNative() throws IOException, ClassNotFoundException {
Student student = init();
System.out.println("原生API序列化============================");
Long start1=System.currentTimeMillis();//初始化时间
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(bos);
Long start2=System.currentTimeMillis();//序列化时间
for(int i=0;i studentCodec= ProtobufProxy.create(Student.class,false);
byte[] bytes=null;
