启动Wildfly时遇到的错误- "jboss.data-source.java:jboss/datasources/SCI_ODS is missing [jboss.jdbc-driv

启动Wildfly时遇到的错误是：

找到wildfly的standlone.xml文件

在上图标记的位置下加上数据源配置
 <datasource jta="true" jndi-name="java:/MySqlDS" pool-name="MySqlDS_Pool" enabled="true" use-java-context="true" use-ccm="true">
                    <connection-url>jdbc:mysql://localhost:3306/taskDB</connection-url>
                    <driver>mysql</driver>
                    <security>
                        <user-name>root</user-name>
                    </security>
                    <timeout>
                        <idle-timeout-minutes>0</idle-timeout-minutes>
                        <query-timeout>600</query-timeout>
                    </timeout>
                </datasource>

在上图标记的drivers下加上下面的代码

 <driver name="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>

如果上面配置完不好使，找到wildfly的安装文件夹，到wildfly-14.0.1.Final\modules\system\layers\base\com这个目录下，新建一个mysql文件夹

在mysql文件夹里新建一个main文件夹

在main文件夹里包含三个文件----如果用过jboss就可以直接包jboss对应的这部分直接挪过来

下面是module.xml文件的内容

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="com.mysql" >
     <resources>
          <resource-root path="mysql-connector-java-5.1.7-bin.jar"/>
     </resources>
     <dependencies>
          <module name="javax.api"/>
          <module name="javax.transaction.api"/>
          <module name="javax.servlet.api" optional="true"/>
     </dependencies>
</module>
