Resteasy 3.5.0.App Engine标准环境最终版-NoSuchFieldError SERVER_SENT_EVENTS_TYPE [英] Resteasy 3.5.0.Final on App Engine standard env - NoSuchFieldError SERVER_SENT_EVENTS_TYPE

问题描述

我有一个使用Resteasy 3.1.4.Final 的漂亮的Java8应用程序，该应用程序部署在App Engine标准环境中.

I have a pretty basic Java8 application using Resteasy 3.1.4.Final deployed in App Engine standard env.

但是当我将Resteasy升级到 3.5.0.Final 时；

But when I upgrade Resteasy to 3.5.0.Final;

• 在我当地的环境中一切都很好
• 部署后，我将获得以下Stacktrace:

因此，这似乎与环境有关. 有解决的线索吗?

So it's seems to be environment related. Any clue to solve it?

谢谢

您好，@ freddyboucher，我认为此提交不负责 您正在处理的NoSuchFieldError. Resteasy 3.1.4.Final是一个 JAX-RS-API 2.0.1规范的实现，而3.5.1.Final是 JAX-RS-API 2.1规范的体现.而你正在谈论的缺失领域 大约来自JAX-RS-API 2.1中的javax.ws.rs.core.MediaType. 因此，您可以确保您的运行时执行未嵌入 JAX-RS-API的版本错误?

Hi @freddyboucher I don't think that this commit is responsible of the NoSuchFieldError you are dealing with. Resteasy 3.1.4.Final is an implementation of the JAX-RS-API 2.0.1 spec whereas 3.5.1.Final is an impl of the JAX-RS-API 2.1 spec. And the missing field you are talking about is coming from the javax.ws.rs.core.MediaType in JAX-RS-API 2.1. So can you please be sure that your runtime execution does not embed the wrong version o the JAX-RS-API ?

让我知道.

他是对的，我在我的pom.xml中:

And he was right, I had in my pom.xml:

  <dependencyManagement>
      <dependencies>
        <dependency>
          <groupId>javax.ws.rs</groupId>
          <artifactId>javax.ws.rs-api</artifactId>
          <version>2.0.1</version>
        </dependency>
      </dependencies>
  </dependencyManagement>

升级到2.1，解决了我的问题！

Upgrading to 2.1, fixed my issue!
