我正在使用 Wildfly 8.2 和 postgresql 9.4 和 java ee 7。我正在做一些关于休息服务的教程。我完全不知道出了什么问题，我没有更改 .xml 中的任何内容，但出现了旧错误，因为我记得我在开始使用我的应用程序时解决了类似的问题（在第一次尝试连接 2 个数据源之后）。当我尝试在服务器上部署我的应用程序时，我得到了这个：

和standalone.xml中的数据源，我通过：9990添加它们。

我尝试 2 安装 jdbc 驱动程序作为我创建的模块 '..\wildfly-8.2.0.Final\modules\system\layers\base\org\postgresql\jdbc\main' 并放入 postgresql-9.4-1201.jdbc41.jar和这个 module.xml
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.postgresql">
<resources>
<resource-root path="postgresql-9.4-1201-jdbc41.jar"/>
</resources>
<dependencies>
<module name="javax.api" />
<module name="javax.transaction.api" />
</dependencies>
</module>
然后我修改standalone.xml并添加：
<datasource jta="true" jndi-name="java:jboss/datasources/PostgreDS" pool-name="PostgresDS" enabled="true" use-java-context="true" use-ccm="true">
<connection-url>jdbc:postgresql://localhost:5432/postgres2</connection-url>
<driver>postgresql</driver>
<security>
<user-name>postgres</user-name>
<password>POSTGRES</password>
</security>
</datasource>
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
<driver name="postgresql" module="org.postgresql">
<xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
</driver>
</drivers>
不工作。当我使用 :9990 控制台时，它看不到驱动程序，我无法正确注册驱动程序模块？
