可以去google下载protobuf的编译器 支持win平台 就是一个exe
下载之后就可用它编译你的proto文件为代码了 我这里编译成了java代码

protoc --java_out=src/main/java -I../src ../src/google/protobuf/descriptor.proto
protoc --proto_path=./ --java_out=./ ./payment.proto
以上是两个编译命令
D:\>protoc --java_out=. xxx.proto
不过我用的是第三个 xxx前面与点之间是有一个空格的 意思是编译输出到目前本地 后面是proto配置文件
protoc就是那个exe文件

//package name not required,if not define and not define java_package, will be out put java file to local
package tutorial;
//java_package not required,if not define,will be not create map dir
option java_package = "com.baidu.protobuf";
//java_outer_classname not required,if not define,The class name will be named proto file name
option java_outer_classname = "AddressBooks";
//required: a well-formed message must have exactly one of this field.
//optional: a well-formed message can have zero or one of this field (but not more than one)
//repeated: this field can be repeated any number of times (including zero) in a well-formed
//message. The order of the repeated values will be preserved.
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;
}
我的配置文件如此
