JBOSS EAP 5.1 を使用しており、マスター/スレーブ メカニズムを実装したいと考えています。xyz-mysql-ds.xml (ex. 顧客データベース用) xyz-mysql-ds.common.xml (共通データベース用)

xyz-mysql-ds.xml にマスター/スレーブ IP を追加しました

<local-tx-datasource>
<jndi-name>customerDS</jndi-name>
<use-java-context>false</use-java-context>    
<connection-url>jdbc:mysql:replication://master_ip_address:3306,slave_ip_address:3306/customer_v2_local?loadBalancePingTimeout=1500;loadBalanceBlacklistTimeout=7000;autoReconnect=true;failOverReadOnly=true;roundRobinLoadBalance=true</connection-url> 

<driver-class>com.mysql.jdbc.ReplicationDriver</driver-class>

JBOSS が正常に起動します。しかし、実行時に次のエラーが発生します。

そして、単語関係を削除すると:<connection-url>jdbc:mysql:replication: 実行時例外なしで動作しますが、すべての読み取り/書き込み要求はマスターのみに送信されます。

この問題を解決するためのヒントはありますか?

ありがとう ！

**最後にこれこれは、プロパティを次のように分離するために機能します&amp;
