大家都知道protobuf好用，可是在网上找到的netty整合protobuf的文章都是千篇一律，自己编写proto文件然后使用工具转java文件用起来复杂麻烦，经过不懈努力终于找到了一个简单的方法希望大家喜欢。

google原生的protobuffer使用起来相当麻烦，首先要写.proto文件，然后编译.proto文件，生成对应的.java文件，鄙人试了一次，发现真的很麻烦。而protostuff的官方网站(http://www.protostuff.io/documentation/runtime-schema/)，对于智商比较低的小编来说也略显生涩，于是鄙人就根据项目中用到的protostuff，撰写此文，以方便自己和他人加深印象和学习。

1.实战

1.maven依赖：

<dependency> <groupId>io.protostuff</groupId> <artifactId>protostuff-core</artifactId> <version>1.4.0</version> </dependency> <dependency> <groupId>io.protostuff</groupId> <artifactId>protostuff-runtime</artifactId> <version>1.4.0</version> </dependency>

2.ProtoBufUtil工具类:ProtoBufUtil.java

import io.protostuff.LinkedBuffer;import io.protostuff.ProtobufIOUtil;import io.protostuff.ProtostuffIOUtil;import io.protostuff.Schema;import io.protostuff.runtime.RuntimeSchema;/** * Created by zhangzh on 2017/2/20. */public class ProtoBufUtil { public ProtoBufUtil() { } public static <T> byte[] serializer(T o) { Schema schema = RuntimeSchema.getSchema(o.getClass()); return ProtobufIOUtil.toByteArray(o, schema, LinkedBuffer.allocate(256)); } public static <T> T deserializer(byte[] bytes, Class<T> clazz) { T obj = null; try { obj = clazz.newInstance(); Schema schema = RuntimeSchema.getSchema(obj.getClass()); ProtostuffIOUtil.mergeFrom(bytes, obj, schema); } catch (InstantiationException e) { e.printStackTrace(); } catch (IllegalAccessException e) { e.printStackTrace(); } return obj; }}

3. bean类Student.java:

import io.protostuff.Tag;/** * Created by zhangzh on 2017/2/20. */public class Student { @Tag(1) private String name; @Tag(2) private String studentNo; @Tag(3) private int age; @Tag(4) private String schoolName; // 关于@Tag,要么所有属性都有@Tag注解,要么都没有,不能一个类中只有部分属性有@Tag注解 public String getName() { return name; } public void setName(String name) { this.name = name; } public String getStudentNo() { return studentNo; } public void setStudentNo(String studentNo) { this.studentNo = studentNo; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getSchoolName() { return schoolName; } public void setSchoolName(String schoolName) { this.schoolName = schoolName; } @Override public String toString() { return "Student{" + "name='" + name + '\'' + ", studentNo='" + studentNo + '\'' + ", age=" + age + ", schoolName='" + schoolName + '\'' + '}'; }}

3.test类ProtoBufUtilTest.java:

import java.util.Arrays;/** * Created by zhangzh on 2017/2/20. */public class ProtoBufUtilTest { public static void main(String[] args) { Student student = new Student(); student.setName("lance"); student.setAge(28); student.setStudentNo("2011070122"); student.setSchoolName("BJUT"); byte[] serializerResult = ProtoBufUtil.serializer(student); System.out.println("serializer result:" + Arrays.toString(serializerResult)); Student deSerializerResult = ProtoBufUtil.deserializer(serializerResult,Student.class); System.out.println("deSerializerResult:" + deSerializerResult.toString()); }}

4.输出结果:

serializer result:[10, 5, 108, 97, 110, 99, 101, 18, 10, 50, 48, 49, 49, 48, 55, 48, 49, 50, 50, 24, 28, 34, 4, 66, 74, 85, 84]
deSerializerResult:Student{name='lance', studentNo='2011070122', age=28, schoolName='BJUT'}
