java – infinispan服务器上的JDBC_PING无法正常工作

我正处于infinispan服务器的实验阶段,我在本地机器上设置infinispan集群时遇到问题.
配置文件：
我通过使用udp stack和jdbc_ping discovery更改jgroup堆栈的一部分来更改配置文件cluster.xml.

 <subsystem xmlns="urn:infinispan:server:jgroups:7.0" default-stack="${jboss.default.jgroups.stack:udp-jdbc}">
        <stack name="udp-jdbc">
            <transport type="UDP" socket-binding="jgroups-udp">
                <property name="ip_mcast">false</property>
    </transport>
            <protocol type="JDBC_PING">
                <property name="connection_url">jdbc:mysql://localhost/jgroups</property>
                <property name="connection_username">root</property>
                <property name="connection_password">root</property>            
                <property name="connection_driver">com.mysql.jdbc.Driver</property>
    </protocol>                
            <protocol type="FD_SOCK" socket-binding="jgroups-udp-fd"/>
            <protocol type="FD_ALL"/>
            <protocol type="VERIFY_SUSPECT"/>
            <protocol type="pbcast.NAKACK2"/>
            <protocol type="UNICAST3"/>
            <protocol type="pbcast.STABLE"/>
            <protocol type="pbcast.GMS"/>
            <protocol type="UFC"/>
            <protocol type="MFC"/>
            <protocol type="FRAG2"/>
            <protocol type="RSVP"/>
        </stack>

我把mysql驱动程序放在文件夹独立/部署中,运行服务器,这就是我输出的内容

从jboss日志中可以看出,子系统infinispan：server：jgroups无法启动,因为没有加载JDBC驱动程序(JDBC_PING需要),但在该步骤之后infinispan服务器成功部署了mysql jdbc驱动程序.在我使用数据源的情况下,同样的错误占用.
有没有办法告诉infinispan：服务器：jgroups子系统在驱动程序加载之前或jndi命名创建之前启动？
或任何有用的解决方法

提前致谢

解决方法:

对于直接JDBC使用,您需要允许JGroups模块加载JDBC驱动程序模块.为此,请将JDBC驱动程序jar作为模块安装,然后打开modules / system / layers / base / org / jgroups / main / module.xml,在依赖项部分下添加JDBC驱动程序模块.

对于使用EAGER缓存进行数据源查找,我认为目前无法在JGroups尝试使用数据源之前确保数据源可用.服务引导顺序由程序依赖性控制,但无法通过配置文件声明依赖性,因此JGroups不会等待数据源.
