将 .jar 部署到 jboss eap 7 时出现反射信息错误

Question

我正在尝试将 ejb jar 文件作为 Maven 项目部署到 jboss eap 7.0.0。该项目使用 Config-1.3.1.jar 作为我已添加到我项目的 pom.xml 的依赖项。我是 jboss 和 maven 的新手，所以我真的不知道我在这里做错了什么。这是 pom.xml

但是当我尝试将 jar 部署到 jboss 时，出现错误：

有谁知道我在这里做错了什么？如果需要，我很乐意 post 更多信息。

你需要想办法让类在这个依赖中：

<dependency>
    <groupId>com.typesafe</groupId>
    <artifactId>config</artifactId>
    <version>1.3.1</version>
    <scope>provided</scope>
</dependency>

可能还有这个：

<dependency>
    <groupId>org.javatuples</groupId>
    <artifactId>javatuples</artifactId>
    <version>1.2</version>
    <scope>provided</scope>
</dependency>

可用于您的 EJB jar。

这通常是通过将这些 jar 与您的 EJB jar 一起打包到一个 EAR 文件中来实现的。

或者，您可以使用 Class Loading in WildFly 10 中描述的方法之一。

最终这取决于您的 EJB 做什么以及它们的客户端（如果有的话）恰好部署在哪里。

例如，将项目的打包类型更改为：

可能更容易

<artifactId>xxx-xxx-xxx-ejb</artifactId>
<packaging>war</packaging>

以便将依赖项添加到 WEB-INF/lib 目录中（如果删除 provided 范围），这比编写 EAR 文件容易得多。

Java EE 6 和 7 允许在 WAR 文件中部署 EJB。
