解決辦法：

Spring 的 contextConfigLocation 配置下的 xml文件的主要內容以下：

<util:properties id="extractAbstractThrift" location="classpath:extractAbstract-thrift.properties" />
    
    <bean id="extractAbstractThriftServer" class="com.demo.thrift.server.ThriftServer">
        <property name="handler" ref="ExtractAbstractServiceHandler"></property>
        <property name="serverType" value="threadselected"></property>
        <property name="protocolType" value="compact"></property>
        <property name="port" value="#{extractAbstractThrift['extractAbstractThrift.port']}"></property>
        <property name="workerSize" value="#{extractAbstractThrift['extractAbstractThrift.worker.size']}"></property>
        <property name="selectorSize" value="#{extractAbstractThrift['extractAbstractThrift.selecter.size']}"></property>
    </bean>
    <bean id="extractAbstractServiceHandler" class="com.demo.search.extractAbstract.service.ExtractAbstractServiceHandler"></bean>

經過檢查xml文件，爲了與 handler 的 ref 相對應，應該把上面的綠色的 extractAbstractServiceHandler，改成 ExtractAbstractServiceHandler 便可。
