ProtoBuf的java使用
碰巧用到Proto，算是笔记吧算是笔记吧， windows : 1，两个文件：proto.exe， protobuf-java-2.4.1.jar 2，建立一个工程TestPb，在下面建立一个proto文件件，用来存放【。proto】文件 3，将proto，exe放在工程下， 4，建立一个msg.proto文件： option java_package = "com.protobuftest.protobuf"; option java_outer_classname = "PersonProbuf"; message Person { required string name = 1; required int32 id = 2; optional string email = 3; enum PhoneType { MOBILE = 0; HOME = 1; WORK = 2; } message PhoneNumber { required string number = 1; optional PhoneType type = 2 [default = HOME]; } repeated PhoneNumber phone = 4; message CountryInfo { required string name = 1; required string code = 2; optional int32 number = 3; } } message AddressBook { repeated Person person = 1; } 5，生成 java文件：在proto.exe目录下：protoc --java_out=./src ./proto/msg.proto6，copy个测试示例了 新建一个文件TestPb.java *********************************************************** package com.protobuftest.protobuf; import java.util.List; import com.google.protobuf.InvalidProtocolBufferException; import com.protobuftest.protobuf.PersonProbuf; import com.protobuftest.protobuf.PersonProbuf.Person; import com.protobuftest.protobuf.PersonProbuf.Person.PhoneNumber; public class TestPb { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub PersonProbuf.Person.Builder builder = PersonProbuf.Person.newBuilder(); builder.setEmail("kkk@email.com"); builder.setId(1); builder.setName("TestName"); builder.addPhone(PersonProbuf.Person.PhoneNumber.newBuilder().setNumber("131111111").setType(PersonProbuf.Person.PhoneType.MOBILE)); builder.addPhone(PersonProbuf.Person.PhoneNumber.newBuilder().setNumber("011111").setType(PersonProbuf.Person.PhoneType.HOME)); Person person = builder.build(); byte[] buf = person.toByteArray(); try { Person person2 = PersonProbuf.Person.parseFrom(buf); System.out.println(person2.getName() + "， " + person2.getEmail()); List<PhoneNumber> lstPhones = person2.getPhoneList(); for (PhoneNumber phoneNumber : lstPhones) { System.out.println(phoneNumber.getNumber()); } } catch (InvalidProtocolBufferException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println(buf); } } *********************************************** ******************************* 生成java文件:PersonProbuf.java ******************************* 工程文件结构：
