创建 Wildfly 10 数据源的问题

Question

我正在尝试在 Wildfly 10 中创建一个数据源以连接 PostgreSQL 9.5 数据库，我已经在 Internet 上看到了一些教程，但我仍然无法做到。

如果有人可以帮助我，我将非常感激。

这是错误信息：enter code here

这就是我创建 module.xml 的方式

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.h2database.h2">
    <resources>
        <resource-root path="h2-1.3.173.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
        <module name="javax.servlet.api" optional="true"/>
    </dependencies>
</module>

这是驱动程序定义：

<driver name="postgres" module="org.postgresql">
    <datasource-class>org.postgresql.Driver</datasource-class>
</driver>

这是数据源定义：

<datasource jndi-name="java:jboss/datasources/CiberWebCopierDS" enabled="true" use-java-context="true" pool-name="CiberWebCopierDS">
    <connection-rl>jdbc:postgresql://localhost:5432/CiberWebCopierDB</connection- url>
    <driver>postgres</driver>
    <security>
        <user-name>postgres</user-name>
        <password>postgresql</password>
    </security>
</datasource

Answer 1

您提供的 module.xml 不是用于 postgres，而是用于 h2 数据库..

尝试使用下面的模块，记得下载postrgres驱动，放在modules/org/postgresql/main中，把“postgresql-Y.X-Z.jdbcV.jar”改成你下载的驱动的名字。

您的配置的其余部分看起来不错，但我不太确定在驱动程序部分设置 datasource-class，我认为在数据源声明中使用 driver-class 元素。

总结一下：

模块.xml

 <?xml version="1.0" encoding="UTF-8"?>  
<module xmlns="urn:jboss:module:1.0" name="org.postgresql">  
 <resources>  
 <resource-root path="postgresql-Y.X-Z.jdbcV.jar"/>  
 </resources>  
 <dependencies>  
 <module name="javax.api"/>  
 <module name="javax.transaction.api"/>  
 </dependencies>  
</module>  

驱动定义

<driver name="postgres" module="org.postgresql"/>

数据源定义

<datasource jndi-name="java:jboss/datasources/CiberWebCopierDS" enabled="true" use-java-context="true" pool-name="CiberWebCopierDS">
    <connection-url>jdbc:postgresql://localhost:5432/CiberWebCopierDB</connection-url>
    <driver-class>org.postgresql.Driver</driver-class>
    <driver>postgres</driver>
    <security>
        <user-name>postgres</user-name>
        <password>postgresql</password>
    </security>
</datasource>

编辑：附带说明，我认为如果要在驱动程序部分声明数据源类，则需要使用 xa-datasource-class 元素而不是 datasource-class，如果需要，可以尝试。
