Java jetty 9.2.3上未设置mongodb会话管理器上的SessionIdManager

我有一个jetty 9.2.3配置和mongodb

我已经配置了mongo连接

 <New id="mongodb" class="com.mongodb.Mongo">
    <Arg>
        <New class="java.util.ArrayList">
            <Call name="add">
                <Arg>
                    <New class="com.mongodb.ServerAddress">
                        <Arg type="java.lang.String">localhost</Arg>
                        <Arg type="int">27017</Arg>
                    </New>
                </Arg>
            </Call>
            <!-- Add more Call statements here as desired --> </New>
    </Arg>

    <Call name="getDB">
        <Arg>HttpSessions</Arg>
        <Call id="sessionDocument" name="getCollection">
            <Arg>sessions</Arg>
        </Call>
    </Call>
    <!-- If you want to configure Jetty to be able to read through the slaves, call the following: -->
    <Call name="slaveOk"/>
</New>

<Set name="sessionIdManager">
    <New id="mongoIdMgr" class="org.eclipse.jetty.nosql.mongodb.MongoSessionIdManager">
        <Arg>
            <Ref id="Server"/>
        </Arg>
        <Arg>
            <Ref id="sessionDocument"/>
        </Arg>
        <Set name="workerName"><Property name="jetty.nosqlSession.workerName" default="node1"/></Set>
        <Set name="scavengePeriod"><Property name="jetty.nosqlSession.scavenge" default="1800"/></Set>
    </New>
</Set>

我不明白，因为setSessionIdManager有SessionIdManager接口，MongoSessionIdManager实现SessionIdManager

任何建议都将不胜感激

谢谢
