将.jar部署到jboss eap时得到反射信息错误7

分类: 技术问答 • 2022-06-15 15:13:40
问题描述：

我试图将ejb jar文件部署到jboss eap 7.0.0作为maven项目。该项目使用Config-1.3.1.jar作为我添加到项目的pom.xml中的依赖项。我是jboss和maven的新手，所以我不知道我在这里做错了什么。下面是pom.xml中将.jar部署到jboss eap时得到反射信息错误7

但是，当我尝试部署罐子到JBoss，我得到的错误（S）：

有谁知道我在做什么这里错了吗？如果需要，我很乐意发布更多信息。

答

你需要找到一种方法，使这种依赖的类：

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

，可能这一个：

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

提供给您的EJB JAR。

这通常是通过将这些jar与您的EJB jar一起打包到EAR文件中来完成的。

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

最终取决于您的EJB的作用以及它们的客户端（如果有）在哪里部署。

例如，它可能会更容易到项目的包装类型更改为：

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

让你的依赖得到在WEB-INF/lib目录下添加（如果去掉provided范围），这是比编写EAR文件要容易得多。

Java EE 6和7允许在WAR文件中部署EJB。
