Prefer not to put .proto files in the same directory as other language sources. Consider creating a subpackage proto for .proto files, under the root package for your project.

Location Should be Language-agnostic

位置應(yīng)與語言無關(guān)

When working with Java code, it's handy to put related .proto files in the same directory as the Java source. However, if any non-Java code ever uses the same protos, the path prefix will no longer make sense. So in general, put the protos in a related language-agnostic directory such as //myteam/mypackage.
使用Java代碼時(shí)，將相關(guān).proto文件和Java資源放在同一目錄下是很方便的。然而，如何任何非Java代碼使用相同proto，路徑前綴將不再有意義。所以通常來說，將proto放入到與語言無關(guān)的目錄中，如//myteam/mypackage.

The exception to this rule is when it's clear that the protos will be used only in a Java context, such as for testing.
這條規(guī)則的例外是當(dāng)很明顯原型將只在 Java 上下文中使用時(shí)，例如用于測(cè)試。
