小编Max*_*Max的帖子

我已经设置了两个在两个私有IP 192.168.2.51和192.168.2.52上运行的MariaDB 10.0 Galera集群节点.我将尝试使用MariaDB网站提供的MariaDB的JDBC Client(org.mariadb.jdbc.Driver)尝试连接到集群.

它使用常规URL,如:"jdbc:mariadb://192.168.2.51:3306,192.168.2.52:3306/dbname".

但我想要实现的是MySQL JDBC驱动程序的可能性,其URL为:"jdbc:mysql://192.168.2.51,192.168.2.52/dbname？autoReconnect = true&autoReconnectForPools = true&failoverReadonly = false&roundRobinLoadBalance = true"

我比较了MariaDB(https://mariadb.com/kb/en/about-the-mariadb-java-client/)和MySQL(http://dev.mysql.com/doc/refman/5.5)中所述的属性./en/connector-j-reference-configuration-properties.html).对于MariaDB JDBC Client,它似乎没有处理loadbalance或autoReconnect的属性.

所以我的问题是:是否有正确的建议方式通过MariaDB JDBC驱动程序连接(具有负载均衡和故障转移功能)到MariaDB Galera,还是应该回到MySQL的ConnectorJ以及ConnectorJ与MariaDB Galera集群的兼容性如何？

谢谢.

我只是将这个作为解决方案发布给那些在Glassfish 4上通过Maven部署使用Datastax的Java驱动程序时遇到错误的人.

正如在Datastax的网站上写的那样,驱动程序的依赖性是:

<dependency>
    <groupId>com.datastax.cassandra</groupId>
    <artifactId>cassandra-driver-core</artifactId>
    <version>1.0.1</version>
</dependency>

不幸的是,如果你通过Maven将它部署到Glassfish 4,它会抛出org.glassfish.deployment.common.DeploymentException:CDI部署失败......就像下面这样:
