以下＆＃34;未知错误＆＃34;如果我尝试使用wildfly-10.1.0.Final Web管理界面创建新的JDBC（数据源）。
> **Unknown error**
>
> Unexpected HTTP response: 500

然后我尝试通过将standalone.xml文件编辑为
来手动完成 <datasource jndi-name="java:jboss/datasources/PostgreSQLDS"
pool-name="PostgreSQLDS" enabled="true" use-java-context="true">
<connection-url>jdbc:postgresql://localhost:5432/School</connection-url>
<driver>postgresql</driver>

</driver>
...
<driver name="mysql" module="com.mysql.driver">
<driver-class>com.mysql.jdbc.Driver</driver-class>
</driver>
...
通过手动添加，现在WildFly Web管理控制台显示新创建的postgress数据源。但是，通过单击WildFLy Web管理控制台中的 测试连接 按钮，它会弹出以下错误消息：
> Failed to create JDBC connection. An internal error occurred. Details
>
> Unexpected HTTP response: 500

> Request {

> "rolled-back" => true
我已将postgress jdbc驱动程序 postgresql-9.4.1210.jre7.jar 文件复制到： C：\ wildfly-10.1.0.Final \ wildfly-10.1.0.Final \模块\ SYSTEM \层\基\有机\的PostgreSQL \主
和module.xml文件也位于同一目录中，编辑为：
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.postgresql">
<resources>
<resource-root path="postgresql-9.4.1210.jre7.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
我的postgrsql数据库名称是学校，连接限制设置为-1
使用postgres失败后我也尝试了mysql但是我从wilefly web界面创建mysql数据源以及手动编辑standalone.xml时得到了完全相同的错误消息。
mysql驱动程序 ＆＃34; mysql-connector-java-5.1.39-bin.jar＆＃34; 位于
C：\ wildfly-10.1.0.Final \ wildfly-10.1.0.Final \模块\ SYSTEM \层\基\ COM \ MySQL的\驱动\主
并在同一位置将module.xml文件创建为：
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.mysql.driver">
<resources>
<resource-root path="mysql-connector-java-5.1.39-bin.jar" />
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
