我继承了一个 wildfly-9 服务器应用程序和一个专用的 MySql 数据库，我正在尝试恢复它。但 wildfly 尝试连接到错误的数据库用户，就好像它忽略了数据源配置中提供的用户/密码。这是我的数据源：
<datasources>
<datasource jndi-name="java:jboss/datasources/crm" pool-name="crm" enabled="true" use-java-context="true">
<connection-url>jdbc:mysql://localhost:3306/crm?zeroDateTimeBehavior=convertToNull&characterEncoding=utf8&characterSetResults=utf8</connection-url>
<driver>mysql</driver>
<pool>
<max-pool-size>30</max-pool-size>
<allow-multiple-users>true</allow-multiple-users>
</pool>
<security>
<user-name>wildfly</user-name>
<password>secret</password>
</security>
<validation>
<valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker"/>
<validate-on-match>true</validate-on-match>
<exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter"/>
</validation>
</datasource>
<drivers>
<driver name="mysql" module="com.sql.mysql">
<driver-class>com.mysql.jdbc.Driver</driver-class>
</driver>
</drivers>
</datasources>
这是我启动 wildlfy 时遇到的错误：

我不明白为什么它尝试以 root 身份连接，特别是因为服务器是以 JBOSS_USER=wildfly 运行的。
