Protobuffer生成java类

protobuffer文件


package tutorial;

option java_package = "com.example.tutorial";
option java_outer_classname = "AddressBookProtos";

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 AddressBook {
  repeated Person person = 1;
}


windows环境里下载protoc.exe
https://developers.google.com/protocol-buffers/docs/downloads


在PersonMsg.proto的文件夹内执行命令：
protoc.exe --java_out=E:\java PersonMsg.proto


如果一个proto文件太大，生成的类代码太多，一个java文件存不下，可以在proto文件里添加

option java_multiple_files = true;

这样，一个proto文件会生成多个java文件
