正如Nicolas所说，将JDBC驱动程序安装为核心模块

As Nicolas says install the JDBC driver as a core module

接下来你需要让你的应用程序依赖于这个模块有两种方法：
MANIEST.MF
jboss-dependency.xml

Next you need to make you application depend on this module there are two ways: MANIEST.MF jboss-dependency.xml

我推荐第一种方式，因为它更符合规范。基本上，您需要在EAR或WAR的META-INF目录中创建MANIFEST.MF文件（无论正在部署什么）。您在文件中创建的行将类似于：

I recommend the first way as it is more spec compliant. Essentially you need to create a MANIFEST.MF file in the META-INF directory of your EAR or WAR (whatever is being deployed). The line you create in the file will be something like:

Dependencies: org.postgresql
