Webapp 失败并显示“JBAS011232: Only one JAX-RS Application Class allowed"向 hadoop-azure 添加 maven 依赖项后 [英] Webapp fails with "JBAS011232: Only one JAX-RS Application Class allowed" after adding a maven dependency to hadoop-azure

问题描述

我有一个在 JBoss EAP 6.4 中运行良好的 web 应用程序.我想向我的 web 应用程序添加一些功能，以便它可以处理驻留在 AzureBlob 存储中的 Parquet 文件.我向 pom.xml 添加了一个依赖项:

I have a webapp that runs fine in JBoss EAP 6.4. I want to add some functionality to my webapp so that it can process Parquet files that reside in AzureBlob storage. I add a single dependency to my pom.xml:

    <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-azure</artifactId>
        <version>3.1.0</version>
    </dependency>

如果我现在尝试启动我的 web 应用程序，它会在启动时失败:

If I now try to start my webapp, it fails at start up:

消息JBAS011232:只允许一个 JAX-RS 应用程序类"似乎是由我的 web 应用程序试图同时使用 RestEasy 和 Jersey 引起的.JBoss 默认使用 RestEasy.显然，hadoop-azure 必须有一个 Jersey 应用程序类.如何通过表明我不想使用基于 Jersey 的应用程序类来消除此问题?

The message "JBAS011232: Only one JAX-RS Application Class allowed" seems to be caused by my webapp trying to use both RestEasy and Jersey. JBoss uses RestEasy by default. Apparently, hadoop-azure must have a Jersey application class. How can I eliminate this problem by indicating that I don't want to use the Jersey-based application class?

推荐答案

hadoop-azure 引入了 hadoop-common，后者引入了 Jersey.在您使用的 hadoop-azure 版本中，hadoop-common 位于 compile .在新版本中，它在 provided 范围内.因此，您可以将 hadoop-azure 依赖项升级到最新的依赖项.如果你需要hadoop-common来编译，那么你可以重新声明hadoop-common并将其放入provided作用域.

hadoop-azure pulls in hadoop-common, which pulls in Jersey. In the version of hadoop-azure you're using, hadoop-common is in compile <scope>. In new version, it is in provided scope. So you can just upgrade the hadoop-azure dependency to the latest one. If you need hadoop-common to compile, then you can redeclare hadoop-common and put it in provided scope.
