Quarkus 本机和 org.kohsuke:github-api - 反序列化异常失败

Question

我正在玩 Quarkus native 和 org.kohsuke:github-api:1.111，我在做简单的 [=17] 时在原生模式下看到 Failed to deserialize 异常=].这适用于 JVM 模式。

主要问题可能是 org.kohsuke:github-api 尚未准备好使用本机模式。我仍然想问一下是否有解决此问题的任何选项，也许 https://github.com/github-api/github-api/blob/master/src/main/java/org/kohsuke/github/GHMyself.java 的一些杰克逊技巧（stacktrace 包含无法构造 org.kohsuke.github.GHMyself 的实例（没有创建者，如默认构造，存在））。

异常详情：

为本机添加依赖项和 quarkus.native.enable-https-url-处理程序属性

    <dependency>
      <groupId>org.kohsuke</groupId>
      <artifactId>github-api</artifactId>
      <version>1.111</version>

        <quarkus.native.enable-https-url-handler>true</quarkus.native.enable-https-url-handler>
      </properties>

更改 GreetingResource

        GitHub github = new GitHubBuilder().withOAuthToken(ghToken).build();
        GHRepository ghRepo = github.getRepository("quarkusio/quarkus");
        return ghRepo.toString();

从 GreetingResourceTest

删除 .body(is("hello"))

运行 mvn clean verify -Dnative

Answer 1

我的猜测是您需要使用 ReflectiveHierarchyBuildItem.

注册所有 GHObject 层次结构以进行反射

因此需要延期。这对平台恕我直言来说是一个有用的补充。

Answer 2

您还可以在任何类

上使用 @RegisterForReflection(targets = GHObject.class)

Answer 3

如果您运行处于本机模式并且得到错误是因为反射解决了用 @RegisterForReflection 注释您的 class 还在您的中添加一个无参数构造函数class 然后重建应用程序，运行您的错误将得到解决。
