org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'ExtractAbstractServiceHandler' is defined
在利用 Spring 集成 thrift 时，报错如下：

解决办法：
Spring 的 contextConfigLocation 配置下的 xml文件的主要内容如下：
<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>
通过检查xml文件，为了与 handler 的 ref 相对应，应该把上面的绿色的 extractAbstractServiceHandler，改为 ExtractAbstractServiceHandler 即可。
