Kotlin 中的枚举注释 [英] Enum annotations in Kotlin

问题描述

我有一个由 Gson 序列化/反序列化的枚举:

I have an enumeration that is serialized/deserialized by Gson:

enum class PacketType {
    NONE;
    [SerializedName("request")]
    REQUEST;
    [SerializedName("response")]
    RESPONSE;
    [SerializedName("event")]
    EVENT;
}

不幸的是，我注意到 Gson 忽略了 SerializedName 注释并使用大写名称作为枚举值.我决定找出序列化无法按预期工作的原因，并发现 Kotlin 删除了枚举值的所有注释.如何使这些注释出现在生成的字节码中?

Unfortunately, I noticed that Gson ignores SerializedName annotations and uses upper case names for enum values. I decided to find out why serialization doesn't work as intended and found out that Kotlin drops all annotations for enum values. How can I make these annotations appear in generated bytecode?

推荐答案

在我看来像是一个错误.请向问题跟踪器报告.

Looks like a bug to me. Please report to the issue tracker.

作为临时解决方法，您可以用 Java 编写此类
