从JBoss应用程序内部调用外部JAX-RS服务时出现问题

jboss maven-2

从JBoss应用程序内部调用外部JAX-RS服务时出现问题,jboss,maven-2,client,jax-rs,resteasy,Jboss,Maven 2,Client,Jax Rs,Resteasy,我对一些我认为应该简单的事情有很多问题： 在我的J2E web应用程序（无状态会话bean）中，我想调用一个外部JAX-RS服务（mailgun）。 我尝试集成Jersey，但遇到了重叠导入的问题（以及NoSuchMethodException等）。所以我没有进一步研究这个问题，而是尝试了RestEasy，因为我知道这是Jboss的标准JAX-RS库 然而，我在这里也遇到了一些问题 你能告诉我调用这些服务的正确路径吗？我非常开放使用任何库，所以如果有一个“内置”的方式来做这件事，我很高兴在这里放

我对一些我认为应该简单的事情有很多问题： 在我的J2E web应用程序（无状态会话bean）中，我想调用一个外部JAX-RS服务（mailgun）。 我尝试集成Jersey，但遇到了重叠导入的问题（以及NoSuchMethodException等）。所以我没有进一步研究这个问题，而是尝试了RestEasy，因为我知道这是Jboss的标准JAX-RS库

然而，我在这里也遇到了一些问题

你能告诉我调用这些服务的正确路径吗？我非常开放使用任何库，所以如果有一个“内置”的方式来做这件事，我很高兴在这里放弃我的依赖地狱

我目前的问题详情：

一旦我从我的无状态SessionBean调用这一行：

    Client client = ClientBuilder.newClient();
    Response res = client.target("https://api.mailgun.net/v2/samples.mailgun.org" +   "/messages").request(MediaType.APPLICATION_FORM_URLENCODED_TYPE).get();
第一行已经生成了一个异常：

    JBAS014134: EJB Invocation failed on component EmailService for method public void de.wohnungsheld.weimea.service.EmailService.hasso(): javax.ejb.EJBException: Unexpected Error
at org.jboss.as.ejb3.tx.CMTTxInterceptor.handleExceptionInOurTx(CMTTxInterceptor.java:163) [jboss-as-ejb3-7.1.0.Final.jar:7.1.0.Final]
...
Caused by: java.lang.NoClassDefFoundError: javax/ws/rs/client/ClientBuilder
我经常玩我的Maven依赖项。 当前版本引用（除其他外）

及

我假设org.jboss.resteasy与此处的其他内容发生冲突

我正在运行JBossAS 7.1

非常感谢

PS：我从我的应用程序中公开了很多JAX-RS服务，效果很好。

如果问题是“为什么我会得到NoClassDefFoundError”，答案是“因为依赖项org.jboss.resteasy.resteasy-jaxrs被标记为已提供，因此在运行时不可用。”

请注意，JBossAS7.1没有使用Reasteasy的3.0.8版本（在您的例子中，可能是Resteasy 2.3.5，但我不知道您使用的${version.JBoss.bom}的值是多少；请检查${version.org.JBoss.Resteasy}的值）

考虑将依赖项jboss-javaee-6.0-with-resteasy添加到pom中，或者使用jboss-javaee-6.0-with-all，这样您就不需要自己设置resteasy的版本

如果要更新JBoss中使用的Resteasy版本，请参阅

如果这是一个选项，您还可以使用WildFly，它支持Resteasy 3.0.6开箱即用
