Wildfly 10无法在启动时加载MySQL XA驱动程序 [英] Wildfly 10 failing to load MySQL XA driver on startup

问题描述

我有一个我在wildfly-10.0.0中部署的Web应用程序。它需要一个mysql xa驱动程序。我有以下错误：

I have a web application I am deploying in wildfly-10.0.0. It requires a mysql xa driver. I have the following error:

2015-10-13 12：25：37,979 ERROR [org.jboss.as.controller.management-操作]（ServerService线程池 - 33）WFLYCTL0013：操作（添加）失败 - 地址：（[
（subsystem=>datasources），

模块目录如下：

03/17/2015  05:21 AM           968,670 mysql-connector-java-5.1.35-bin.jar

module.xml文件是：

The module.xml file is:

   <?xml version="1.0" encoding="UTF-8"?>    

<module xmlns="urn:jboss:module:1.1" name="com.mysql">  
  <resources>  
    <resource-root path="mysql-connector-java-5.1.35-bin.jar"/>  
  </resources>  
  <dependencies>  
    <module name="javax.api"/>
    <module name="javax.transaction.api"/>      
  </dependencies>  
</module>  

我将驱动程序和数据源添加到standalone.xml的datasources部分：

I added the driver and datasource to the datasources section of standalone.xml:

<xa-datasource jndi-name="java:/jdbc/MyXaDS" pool-name="MyXaDSPool" enabled="true" use-ccm="false">
                <xa-datasource-property name="URL">

            <drivers>
                <driver name="com.mysql" module="com.mysql">
                    <driver-class>com.mysql.jdbc.Driver</driver-class>
                    <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
                </driver>
            </drivers>

推荐答案

你得到的错误意味着wildfly需要一个名为 com.mysql 但它不存在或未以该名称注册。

The error you get means that wildfly expects a module called com.mysql but it doesn't exist or it isn't registered under that name.

您缺少一步，即注册数据源jdbc驱动程序。第一步当然是添加 mysql-connector-java-5.1.35-bin.jar 文件和 module.xml 中的文件WILDFLY_HOME\modules\system\layers\base\com\mysql\main 。

You are missing one step, which is registering the datasource jdbc driver. The first step of course being adding the mysql-connector-java-5.1.35-bin.jar file and module.xml file in WILDFLY_HOME\modules\system\layers\base\com\mysql\main.

要消除错误，请停止wildfly，删除这些行，删除standalone.xml中的驱动程序声明;我们将让/ subsystem命令创建此条目。

To get rid of your error, stop wildfly, delete the the driver declaration in your standalone.xml by removing these lines; We'll let the /subsystem command create this entry.

<driver name="com.mysql" module="com.mysql">
     <driver-class>com.mysql.jdbc.Driver</driver-class>
     <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>

打开命令提示符并导航到 WILDFLY_HOME\bin\ 并运行以下命令。

Open your command prompt and navigate to WILDFLY_HOME\bin\ and run the following commands.

1. 运行以下命令连接到jboss cli： jboss -cli.bat --connect 。如果您的管理控制台在另一个端口上运行，例如localhost：9991，请使用 jboss-cli.bat --connect --controller = 127.0.0.1：9991

1. Connect to jboss cli by running : jboss-cli.bat --connect . In case your management console is running on a different port say , localhost:9991, use jboss-cli.bat --connect --controller=127.0.0.1:9991

然后使用以下命令注册jdbc-driver

Then register the jdbc-driver with the following command

/ subsystem =数据源/ JDBC驱动器= com.mysql：添加（驱动程序名称= com.mysql，驱动器模块名= com.mysql，驾驶员XA-数据源类名= com.mysql.jdbc.jdbc2.optional。 MysqlXADataSource）

你应该得到回复 {结果=> 成功} 如果成功的话。
从那里，重新加载你的服务器，你应该摆脱那个错误。

You should get the response {"outcome" => "success"} if this was successful. From there, reload your server and you should get rid of that error.
