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.proto
6,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 stubPersonProbuf.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 blocke.printStackTrace();} System.out.println(buf); } }***********************************************
*******************************生成java文件:PersonProbuf.java *******************************工程文件结构：
笔记到此结束。。。是不是该睡觉了。。。。。。。。。。。。。。。。。
