我正在使用 WSO2 数据服务服务器 (v3.0.1)，我想知道是否可以在 JNDI 中自动注册 custom-datasources.xml 中定义的特定数据源（不使用控制台 mgmt）。

我试图通过这种配置来实现这一点：

    <datasource>
        <name>IPL_DS_IDB</name>
        <description>My custom datasource</description>
        <jndiConfig>
            <name>IPL_DS_DB</name>
            <environment>
                <property name="jndi.use.data.source.factory">true</property>
                <property name="java.naming.factory.initial">com.sun.jndi.rmi.registry.RegistryContextFactory</property>
                <property name="java.naming.provider.url">rmi://localhost:10002</property>
            </environment>
        </jndiConfig>
        <definition type="RDBMS">
            <configuration>
                <url>jdbc:mysql://192.168.1.5:3306/idb</url>
                <username>wso2user_idb</username>
                <password>XXXXXXX</password>
                <driverClassName>com.mysql.jdbc.Driver</driverClassName>
                <maxActive>50</maxActive>
                <maxWait>60000</maxWait>
                <testOnBorrow>true</testOnBorrow>
                <validationQuery>SELECT 1</validationQuery>
                <validationInterval>30000</validationInterval>
            </configuration>
        </definition>
    </datasource>

但是当我使用这种配置启动数据服务服务器时，我遇到了这个异常：

有人可以帮忙吗？

useDataSourceFactory应设置为jndiConfig元素的属性。因此，您的数据源配置应如下所示。

<datasource>
        <name>IPL_DS_IDB</name>
        <description>My custom datasource</description>
        <jndiConfig useDataSourceFactory="true">
            <name>IPL_DS_DB</name>
            <environment>
                <property name="java.naming.factory.initial">com.sun.jndi.rmi.registry.RegistryContextFactory</property>
                <property name="java.naming.provider.url">rmi://localhost:10002</property>
            </environment>
        </jndiConfig>
        <definition type="RDBMS">
            <configuration>
                <url>jdbc:mysql://192.168.1.5:3306/idb</url>
                <username>wso2user_idb</username>
                <password>XXXXXXX</password>
                <driverClassName>com.mysql.jdbc.Driver</driverClassName>
                <maxActive>50</maxActive>
                <maxWait>60000</maxWait>
                <testOnBorrow>true</testOnBorrow>
                <validationQuery>SELECT 1</validationQuery>
                <validationInterval>30000</validationInterval>
            </configuration>
        </definition>
    </datasource>
