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
