Quarkus原生代和组织：github-api - 未能反序列化异常

Question

我在玩Quarkus本机和org.kohsuke： github-api： 1.111，我看到在执行简单的new GitHubBuilder（）. with OAuthToken（ghToken）. build（）；时，无法在本机模式下反序列化异常。这在JVM模式下工作。

主要的问题可能是org.kohsuke：github-api还没有为本机模式做好准备。我仍然想问一下是否有任何选项可以解决这个问题，也许是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（堆栈跟踪包含无法构造org.kohsuke.github.GHMyself的实例（不存在创建者，如默认构造））。

Answer 1

如果您在本机模式下运行，并且错误是由于反射导致的。请使用＜code＞@RegisterForReflection＜/code＞注释您的类。请在类中添加一个无参数构造函数，然后重新生成应用程序并运行。您的错误将得到解决。

如需更多参考，请参阅链接上的quarkus指南

Answer 2

我猜您需要使用ReflectiveHierarchyBuildItem注册所有GHObject层次结构以进行反射。

所以这需要延期。这将是对IMHO平台的有益补充。

Answer 3

您还可以在任何类上使用@Register sterForReflection（目标=GHObject.class）
