在Wildfly中与战争部署共享util jar文件

Question

假设我有一个名为'util.jar'的jar文件。这个jar文件主要包含JPA实体和一些类（没有EJB）。如何让这个jar可用于在Wildfly中部署的所有战争（不需要将jar放入战争的WEB-INF/lib中）？

我thied创造Wildfly模块：

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

    <dependencies> 
    </dependencies> 
</module> 

，并在我的战争MANIFEST.MF文件：

Dependencies: br.edu.ufca export 

，但我得到的各种误差修改的，像这样的：

UPDATE

现在的工作。我加了以下相关：

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

Answer 1

创建一个自定义模块，并确定该模块的依赖性是刚刚部署的jar文件到应用服务器的替代（f.i. ufca.jar）。一旦部署了jar，您可以使用f.i从war文件中声明对此部署的依赖关系。 deployment.ufca.jar作为id。

在你的战争文件中，你可以f.i.使用jboss-deployment-structure.xml来添加依赖项f.i.使用

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

参见：https://docs.jboss.org/author/display/WFLY8/Class+Loading+in+WildFly

Answer 2

如果真正需要的技术原因，可以允许部署访问您的模块课程由于这样的部分配置：

<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，当然首先用于DataSource，但也因为应用程序代码需要访问实现类。

如果您想要在多个独立部署之间共享大量依赖关系，那么这是一种节省内存的好方法。
