Quarkus - org.jboss.resteasy.reactive.common.core.BlockingNotAllowedException：尝试在 io 线程上进行阻塞读取

Question

我有一个 rest 端点，它读取请求正文并映射到 Java POJO。

我面临的问题是当我将请求作为 GET 发送时出现以下异常。 但是当我将类型更改为 POST 并且请求成功时，不会引发异常。

@Path("/test")
@GET
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Uni<List<String>> getData(ReqeustBody requestBody) {
//app code
}

我的想法是，将请求主体映射到 pojo 的 jackson 库导致异常。 但是为什么它只对 GET 而不是 POST 失败。

任何线索都会有所帮助。

看起来resteasy-jaxrs 不允许使用主体调用 HTTP get 方法。 与替代解决方案类似的问题： Can RestEasy 为@GET 方法序列化 POJO？
