分布式网上商城项目-solr搜索功能错误

 

一、RuntimeException错误

可是查看target文件发现查看报错信息能够看见是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

 

二、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&timestamp=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

可是检查search层在查询数据库先后打印

1 System.out.println("开始查询商品！"); 2 
3 List<SearchItem> items = mapper.searchItemList(); 4 
5 //二、建立solrServer对象，将商品信息经过SolrInputDocument存入
6 
7 System.out.println("查询到的商品数量："+items.size());

而且打印出来了数听说明mapper映射文件也没有问题。从新开始测试，发现后台两条数据都打印了出来，证实请求从controller层传递到了service层，dubbo链接没有问题。

那证实一件事情就是此次链接由于要链接solr致使耗时很长，使得超出了dubbo的默认链接时间从而失败，修改dubbo在service层和controller层的配置：

 1 <!-- 名字不可以重复，和随便，用于计算依赖关系，服务调用的状况 -->
 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数据修改链接超时为5分钟，再次测试，链接成功

 

 

Solr数据导入成功
