本文主要是介绍Google protobuffer序列化工具使用以及与idea集成，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

创建Maven项目，pom.xml文件添加如下内容：
<properties><protobuf.version>3.6.1</protobuf.version><grpc.version>1.18.0</grpc.version></properties><dependencies><dependency><groupId>com.google.protobuf</groupId><artifactId>protobuf-java</artifactId><version>${protobuf.version}</version></dependency></dependencies><build><extensions><extension><groupId>kr.motd.maven</groupId><artifactId>os-maven-plugin</artifactId><version>1.5.0.Final</version></extension></extensions><plugins> <!-- 编译google protobuffer --><plugin><groupId>org.xolstice.maven.plugins</groupId><artifactId>protobuf-maven-plugin</artifactId><version>0.5.0</version><configuration><protocArtifact>com.google.protobuf:protoc:${protobuf.version}:exe:${os.detected.classifier}</protocArtifact><pluginId>grpc-java</pluginId>
<pluginArtifact>io.grpc:protoc-gen-grpc-java:${grpc.version}:exe:${os.detected.classifier}</pluginArtifact></configuration><executions><execution><goals><goal>compile</goal><goal>compile-custom</goal></goals></execution></executions></plugin></plugins></build>在main目录下新建proto文件夹，并将该文件夹设置为源代码目录（编译时会自动去这个目录下找proto文件），如下图：
在该目录下编写proto文件，这里写各测试的Person.proto，内容如下：
syntax = "proto3"; //标识是protobuffer3 ，默认是2package protobuffer.proto;
option java_package = "com.heavy.learn.protobuffer";
option java_outer_classname = "PersonPB";message Person {sint64 id = 1;int32 age = 2;string name=3;repeated float exam = 4;bool good =5;bytes byt = 6;double d = 7 ;enum Level {NORMAL= 0;GOOD= 1;BAD = 2;}Level level = 8;map<string,list> map = 9;message list{repeated Person ele=1;}
}message Family{repeated Person p =1;
}使用protobuf下的compile来编译，会生成java代码：
编写测试类，来使用序列化与反序列化
package com.heavy.learn.protobuffer;import com.google.protobuf.InvalidProtocolBufferException;import java.util.List;public class ProtoTest {public static void main(String[] args) {PersonPB.Person.Builder person = PersonPB.Person.newBuilder();person.setAge(12);person.setId(1);person.setName("Jacky");person.setExam(0,2.3f);person.setExam(1,2.4f);//设置mapperson.putMap("a",null);PersonPB.Family.Builder fa = PersonPB.Family.newBuilder();fa.addP(person);System.out.println(person);//序列化PersonPB.Person pinfo = person.build();byte[] barr = pinfo.toByteArray();System.out.println(barr.length);try {//反序列化PersonPB.Person p= PersonPB.Person.parseFrom(barr);System.out.println(p);//获取listp.getExamList();PersonPB.Family f = PersonPB.Family.parseFrom(fa.build().toByteArray());List<PersonPB.Person> list = f.getPList();for(PersonPB.Person px : list){System.out.println(px.getAge());}} catch (InvalidProtocolBufferException e) {e.printStackTrace();}}}
