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，但是得到了旧的错误，我记得当我开始使用我的应用程序时（第一次尝试连接2个数据源后）我解决了类似的问题。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，我将它们添加到：9990。

我尝试了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>
不起作用。当我使用：9990控制台它没有看到驱动程序，我无法正确注册驱动程序模块？
答案 0 :(得分：1)
standalone.xml - ＆gt;的PostgreSQL-9.3-1102.jdbc41.jar
模块中的配置 - ＆gt;的PostgreSQL-9.4-1201-jdbc41.jar
在任何情况下，Wildfly都会建议直接在服务器上部署驱动程序，而不是创建模块。
答案 1 :(得分：0)
一个疯狂的猜测：修改过的 standalone.xml 中的拼写错误：Postgre[s]DS？
