【问题描述】：

我在我的 SBB 中使用 Jdbc 资源适配器 7.1.15。它适用于单个数据源。现在我需要从我的 SBB 内部与第二个数据源通信，但我找不到这样做的方法。

我尝试更新 resources/jdbc/ra/src/main/resources/META-INF/ 中的 resource-adaptor-jar.xml。通过为 DATASOURCE_JNDI_NAME 添加另一个配置属性，如下所示

<resource-adaptor ignore-ra-type-event-type-check="True">

    <resource-adaptor-name>JdbcResourceAdaptor</resource-adaptor-name>
    <resource-adaptor-vendor>org.restcomm</resource-adaptor-vendor>
    <resource-adaptor-version>1.0</resource-adaptor-version>

    <resource-adaptor-type-ref>
        <resource-adaptor-type-name>JDBCResourceAdaptorType</resource-adaptor-type-name>
        <resource-adaptor-type-vendor>org.restcomm</resource-adaptor-type-vendor>
        <resource-adaptor-type-version>1.0</resource-adaptor-type-version>
    </resource-adaptor-type-ref>

    <resource-adaptor-classes>
        <resource-adaptor-class>
            <resource-adaptor-class-name>
                org.restcomm.slee.resource.jdbc.JdbcResourceAdaptor
            </resource-adaptor-class-name>
        </resource-adaptor-class>
    </resource-adaptor-classes>

    <config-property>
        <config-property-name>DATASOURCE_JNDI_NAME</config-property-name>
        <config-property-type>java.lang.String</config-property-type>
        <config-property-value>java:/ExampleDS</config-property-value>    
    </config-property>
            <config-property>
        <config-property-name>DATASOURCE_JNDI_NAME</config-property-name>
        <config-property-type>java.lang.String</config-property-type>
        <config-property-value>java:/ExampleDS_2</config-property-value>    
    </config-property>
    <config-property>
        <config-property-name>EXECUTOR_SERVICE_THREADS</config-property-name>
        <config-property-type>java.lang.Integer</config-property-type>
        <config-property-value>4</config-property-value>
    </config-property>

    <config-property>
        <config-property-name>RA_SBB_INTERFACE_CONNECTION_GETTERS_ON</config-property-name>
        <config-property-type>java.lang.Boolean</config-property-type>
        <config-property-value>true</config-property-value>
    </config-property>

</resource-adaptor>

但是一旦我部署它，我就会收到部署错误。我的问题是，有没有办法将 jdbc RA 配置为同时使用两个或多个数据源？

【解决方案1】：

为了让 Restcomm SLEE Jdbc 资源适配器有多个数据源，您需要首先更改 restcomm-slee-ra-jdbc 和 restcomm-slee 中的 resource-adaptor-jar.xml 和 deploy-config.xml 文件-ra-jdbc-DU 项目，分别。下面是定义了两个 JdbcResourceAdaptor 的 resource-adaptor-jar.xml 示例。每个数据源一个。

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE resource-adaptor-jar PUBLIC "-//Sun Microsystems, Inc.//DTD JAIN SLEE Resource Adaptor 1.1//EN" "http://java.sun.com/dtd/slee-resource-adaptor-jar_1_1.dtd">

    <resource-adaptor ignore-ra-type-event-type-check="True">

            <resource-adaptor-type-vendor>org.restcomm</resource-adaptor-type-vendor>
            <resource-adaptor-type-version>1.0</resource-adaptor-type-version>
        </resource-adaptor-type-ref>

        <resource-adaptor-classes>
            <resource-adaptor-class>
                <resource-adaptor-class-name>

        </resource-adaptor-classes>

        </config-property>

        <config-property>
            <config-property-name>RA_SBB_INTERFACE_CONNECTION_GETTERS_ON</config-property-name>
            <config-property-type>java.lang.Boolean</config-property-type>
            <config-property-value>true</config-property-value>
        </config-property>

    </resource-adaptor>

    <resource-adaptor ignore-ra-type-event-type-check="True">

            <resource-adaptor-type-version>1.0</resource-adaptor-type-version>
        </resource-adaptor-type-ref>

        <resource-adaptor-classes>
            <resource-adaptor-class>
                <resource-adaptor-class-name>

                </resource-adaptor-class-name>
            </resource-adaptor-class>
        </resource-adaptor-classes>

        <config-property>
              <config-property-name>DATASOURCE_JNDI_NAME</config-property-name>
                  <config-property-type>java.lang.String</config-property-type>
                  <config-property-value>java:/AppConfigDS</config-property-value>    
                </config-property>                

        <config-property>
            <config-property-name>EXECUTOR_SERVICE_THREADS</config-property-name>
            <config-property-type>java.lang.Integer</config-property-type>
            <config-property-value>4</config-property-value>
        </config-property>

        <config-property>
            <config-property-name>RA_SBB_INTERFACE_CONNECTION_GETTERS_ON</config-property-name>
            <config-property-type>java.lang.Boolean</config-property-type>
            <config-property-value>true</config-property-value>
        </config-property>

    </resource-adaptor>        

</resource-adaptor-jar>

然后需要使用实体名称更新 deploy-config.xml。在我的例子中，我创建了实体名称 JDBCRA 和 JDBCRA-Config。 JDBCRA 将是应用程序统计的数据源，而 JDBCRA-Config 将是应用程序配置的数据源。

    <?xml version="1.0" encoding="UTF-8"?>
<deploy-config>
    <ra-entity
        resource-adaptor-id="ResourceAdaptorID[name=JdbcResourceAdaptor,vendor=org.restcomm,version=1.0]"
        entity-name="JDBCRA">
        <properties/>
        <ra-link name="JDBCRA" />
    </ra-entity>
    <ra-entity
        resource-adaptor-id="ResourceAdaptorID[name=JdbcResourceAdaptor,vendor=org.restcomm,version=1.0]"
        entity-name="JDBCRA-CONFIG">
        <properties/>
        <ra-link name="JDBCRA-CONFIG" />
    </ra-entity>        
</deploy-config>

然后更新 WildFly 应用服务器 (restcomm-slee-7.1.83.87-wildfly-10.1.0.Final) 的standalone.xml 以包含两个数据源：

 <subsystem xmlns="urn:jboss:domain:datasources:4.0">
  ...
                <datasource jndi-name="java:/STATS_DS" pool-name="STATS_DS">
                    <connection-url>jdbc:postgresql://localhost:5432/appstats</connection-url>
                    <driver>postgres</driver>
                    <pool>
                        <min-pool-size>20</min-pool-size>
                        <initial-pool-size>50</initial-pool-size>
                        <max-pool-size>150</max-pool-size>
                    </pool>
                    <security>
                        <user-name>user</user-name>
                        <password>password</password>
                    </security>
                </datasource>
                <datasource jndi-name="java:/AppConfigDS" pool-name="AppConfigDS">
                    <connection-url>jdbc:postgresql://localhost:5432/appconfig</connection-url>
                    <driver-class>org.postgresql.Driver</driver-class>
                    <driver>postgres</driver>
                    <security>
                        <user-name>username</user-name>
                        <password>password</password>
                    </security>
                </datasource>
 ...
            </datasources>
        </subsystem>

其次，在您的 JAIN-SLEE 应用程序中定义两个 SBB，即 StatsDataSourceSBB 和 ConfigDataSourceSBB。在 JAIN-SLEE 应用程序的 sbb-jar.xml 中配置每个 SBB，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE sbb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD JAIN SLEE SBB 1.1//EN"
                         "http://java.sun.com/dtd/slee-sbb-jar_1_1.dtd">

       </sbb>

这应该允许您为 Restcomm JAIN-SLEE JDBC RA 定义多个数据源。

希望这会有所帮助。
