Java 在Wildfly中与war部署共享util jar文件

假设我有一个名为“util.jar”的jar文件。这个jar文件主要包含JPA实体和一些Util类（没有EJB）。我如何使这个jar对部署在Wildfly中的所有war都可用（而不将jar放在war的WEB-INF/lib中）

我想在Wildfly中创建一个模块：

<module xmlns="urn:jboss:module:1.3" name="br.edu.ufca">
    <resources>
        <resource-root path="ufca.jar"/>
    </resources>

    <dependencies>
    </dependencies>
</module>

但我有各种各样的错误，比如：

多谢各位

更新

它现在起作用了。我添加了以下依赖项：

<dependencies>
    <module name="javaee.api"/>
    <module name="javax.faces.api"/>
</dependencies>

---

创建自定义模块并定义对该模块的依赖关系的替代方法是将jar文件部署到应用程序服务器（f.i.ufca.jar）。一旦部署了jar，您就可以使用f.i.deployment.ufca.jar作为id，从war文件声明对此部署的依赖关系

在war文件中，您可以使用jboss-deployment-structure.xml添加依赖项

<dependencies>
  <module name="deployment.ufca.jar" />
</dependencies>

---

另请参见：

如果出于技术原因确实需要，可以通过配置中的以下部分允许部署访问您的模块类：

<subsystem xmlns="urn:jboss:domain:ee:1.0" >            
  <global-modules>
    <module name="br.edu.ufca" slot="main" />            
  </global-modules> 
</subsystem>

我通常在发布JDBC驱动程序时使用这种方式，首先当然是针对数据源，但也因为应用程序代码需要访问实现类

---

如果您想在多个独立部署之间共享大量依赖项，这是一种节省内存的好方法。

您能再详细说明一下吗？哦，我发现我的答案已损坏。我会在通话结束后尽快编辑它。我不明白f.I.部分。这是MANIFEST.MF文件中的条目吗？您能否再次更新您的答案，以包含如何在war文件中声明依赖关系的示例？谢谢。我想我们快到了。正如您所看到的，我的jar（ufca.jar）依赖于模块javax.faces.api，该模块是在我为我的jar创建模块时设置的。但我在试图在“jboss部署结构xml”文件中指定此依赖关系时遇到问题，这就是为什么我会遇到与以前相同的错误。您能否再次更新您的答案以添加此依赖项？再次感谢。好的，jar的依赖项必须在jar中声明，而不是war。因此，将依赖项作为逗号分隔的列表添加到jar的MANIFEST.MF中，如下所示：dependencies:javaee.api，javax.faces.api这在我发布的类加载文档中也有解释。这非常有用！非常感谢。

<subsystem xmlns="urn:jboss:domain:ee:1.0" >            
  <global-modules>
    <module name="br.edu.ufca" slot="main" />            
  </global-modules>
