淘淘商城几个错误

Error creating bean with name 'itemController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.taotao.service.ItemService com.taotao.controller.ItemController.itemService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'itemService': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: Failed to check the status of the service com.taotao.service.ItemService. No provider available for the service com.taotao.service.ItemService from the url zookeeper://127.0.0.1:2181/com.alibaba.dubbo.registry.RegistryService?application=taotao-manager-web&dubbo=2.5.3&interface=com.taotao.service.ItemService&methods=getItemById&pid=928&revision=1.0-SNAPSHOT&side=consumer&timestamp=1527688447224 to the consumer 169.254.10.106 use dubbo version 2.5.3

看到上面错误提示,发现已经去连接zookeeper了,但没有发现服务提供者.这是表现层先于服务端启动造成的,解决方法就是按顺序先启动service服务端,再启动web表现层.

Invalid bound statement (not found): com.taotao.mapper.ItemMapper.selectByPrimaryKey

ibatis绑定异常,无效的绑定,找不到对应的实现

具体表现,target-classes里面只有mapper没有xml,所以会报这个错.

解决方法:

 

1. <resources>  
2.             <resource>  
3.                 <directory>src/main/resources</directory>  
4.                 <includes>  
5.                     <include>**/*.properties</include>  
6.                     <include>**/*.xml</include>  
7.                 </includes>  
8.                 <filtering>false</filtering>  
9.             </resource>  
10.             <resource>  
11.                 <directory>src/main/java</directory>  
12.                 <includes>  
13.                     <include>**/*.xml</include>  
14.                 </includes>  
15.                 <filtering>false</filtering>  
16.             </resource>  
17.         </resources>  

问题描述
今天在做项目时，遇到一个错误：“Result Maps collection already contains value for com.xxx.dao.tb_userMapper.BaseResultMap”
二、原因分析

    Mybatis-Generator在生成Mapper.xml文件时，会在原来基础上再生成，导致内容重复。

解决方法:删除多余的,或者重新生成
