但是查看target文件发现查看报错信息可以看见是mapper绑定无效
Mapper文件已经放置在一个文件夹，再检查两个文件发现是select语句的ID没有对应上
2、请求超时错误
1 com.alibaba.dubbo.rpc.RpcException: Failed to invoke the method importAllItems in the service cn.thyonline.taotao.search.service.SearchItemService. Tried 3 times of the providers [192.168.199.139:20882] (1/1) from the registry 192.168.25.128:2181 on the consumer 192.168.199.139 using the dubbo version 2.5.3. Last error is: Invoke remote method timeout. method: importAllItems, provider: dubbo://192.168.199.139:20882/cn.thyonline.taotao.search.service.SearchItemService?anyhost=true&application=taotao-manager-web&check=false&dubbo=2.5.3&interface=cn.thyonline.taotao.search.service.SearchItemService&methods=importAllItems&pid=3208&revision=0.0.1-SNAPSHOT&side=consumer×tamp=1528390391677, cause: Waiting server-side response timeout. start time: 2018-06-08 00:53:16.967, end time: 2018-06-08 00:53:17.968, client elapsed: 0 ms, server elapsed: 1001 ms, timeout: 1000 ms, request: Request [id=2, version=2.0.0, twoway=true, event=false, broken=false, data=RpcInvocation [methodName=importAllItems, parameterTypes=[], arguments=[], attachments={path=cn.thyonline.taotao.search.service.SearchItemService, interface=cn.thyonline.taotao.search.service.SearchItemService, version=0.0.0}]], channel: /192.168.199.139:11038 -> /192.168.199.139:20882
Web层请求超时
但是检查search层在查询数据库前后打印
1 System.out.println("开始查询商品！");
2
3 List<SearchItem> items = mapper.searchItemList();
4
5 //2、创建solrServer对象，将商品信息通过SolrInputDocument存入
6
7 System.out.println("查询到的商品数量："+items.size());
并且打印出来了数据说明mapper映射文件也没有问题。重新开始测试，发现后台两条数据都打印了出来，证明请求从controller层传递到了service层，dubbo连接没有问题。
那证明一件事情就是这次连接因为要连接solr导致耗时很长，使得超出了dubbo的默认连接时间从而失败，修改dubbo在service层和controller层的配置：
1 <!-- 名字不能够重复，和随便，用于计算依赖关系，服务调用的情况 --> 2 3 <dubbo:application name="taotao-search" /> 4 5 <!-- 使用zookeeper注册协议 --> 6 7 <dubbo:registry protocol="zookeeper" address="192.168.25.128:2181" /> 8 9 <!-- 使用dubbo协议，暴露服务的端口 --> 10 11 <dubbo:protocol name="dubbo" port="20882" /> 12 13 <!-- 发布服务 --> 14 15 <dubbo:service interface="cn.thyonline.taotao.search.service.SearchItemService" ref="searchItemServiceImpl" timeout="300000"/>
查看solr数据修改连接超时为5分钟，再次测试，连接成功
Solr数据导入成功
