Question

我有一个RestEasy客户端，我想在部署到Tomee的REST服务中使用。一切都很好，但在部署时我得到错误

我尝试过使用不同版本的RestEasy和Tomee，但错误并没有改变。目前我在tomee中使用RestEasy 3.5.1.Final：8-jre-7.0.4-plus Docker容器。

不幸的是，谷歌并没有帮助我解决这个问题......

我也刚开始工作。带有RestEasy的TomEE Plus 7.1.0

这是需要做的：

为避免出现“不是SERVER提供程序”异常，需要将系统属性“ openejb.jaxrs.fail-on-constrainedto”设置为false。此功能来自CxfRsHttpListener类。
TomEE Plus 7.1.0使用Java 8，但是在“ lib”文件夹中有一个名为“ javaee-api-7.0-1.jar”的jar。 TomEE启动时，无论您在maven或gradle中配置为项目依赖项，它都会使用该文件夹中的所有jar。而且，您将获得JavaEE 7类的机会很大。

RestEasy 3.5.1.Final是JAX-RS-API 2.1规范的实现。因此，使用JavaEE7，您将在MediaType中获得异常NoSuchFieldError SERVER_SENT_EVENTS_TYPE。

为避免这种情况，您需要使用Resteasy 3.1.4.Final，它是JAX-RS-API 2.0.1规范的实现
