协议缓冲区：如何导入？ [英] Protocol Buffer: How to import?

问题描述

我有2个.proto文件：

I have 2 .proto files :

第一个文件：

package com.test.model;

message ProtoModel  {
    required CustomObj custom=1;
}

第二档：

package com.test.model;

message CustomObj {
    required string smth=1;
}

这里的问题是CustomObj被称为未解析的参考 。
因此，我试图将第二个文件导入第一个文件：

The issue here is that "CustomObj" is said to be "unresolved reference" . Thus, I've tried to import the second file into first file:

import "com/test/model/firstFile.proto"

package com.test.model;    

message ProtoModel  {
    required CustomObj custom=1;
}

我仍然遇到同样的问题!!

I still get the same issue !!

推荐答案

import语句是相对于您调用 protoc 的地方的文件夹。
看起来你已将它视为相对于包而言。

The import statement is the folder relative to the place where you invoke protoc. It looks like you have treated it as relative to the package instead.

例如。如果（像我一样）你将这两个文件存储在 src / main / resources 中，你可以按如下方式调用protoc：

e.g. if (like me) you store both files in src/main/resources, you'd invoke protoc as follows:

protoc src/main/resources/firstFile.proto src/main/resources/secondFile.proto --java_out=src/generated/java

并且您的import语句将是 importsrc / main / resources / firstFile.proto

and your import statement would be import "src/main/resources/firstFile.proto"

如果您想根据包名将文件存储在子文件夹中，那么您只需在顶级foldername之后相应地添加它。

If you want to store the files in subfolders according to package name, then you just add this accordingly, after the top-level foldername.
