Fre*_*her 5 java rest google-app-engine resteasy
我有一个使用Resteasy 3.1.4.Final的相当基本的Java8应用程序,已部署在App Engine标准环境中。
但是当我将Resteasy升级到3.5.0.Final时;
来自org.jboss.resteasy.core.ResourceMethodInvoker.isSseResourceMethod(ResourceMethodInvoker.java:162)的servlet

因此,这似乎与环境有关。有解决的线索吗?
谢谢
我正在发布我在Github 中收到的@NicoNes 的回答
嗨@freddyboucher 我不认为这次提交是你正在处理的 NoSuchFieldError 的原因。Resteasy 3.1.4.Final 是 JAX-RS-API 2.0.1 规范的实现,而 3.5.1.Final 是 JAX-RS-API 2.1 规范的实现。您正在谈论的缺失字段来自 JAX-RS-API 2.1 中的 javax.ws.rs.core.MediaType。那么您能否确保您的运行时执行没有嵌入错误的 JAX-RS-API 版本?
让我知道。

他是对的,我在 pom.xml 中有:
<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!
