不是吧 假的

本人初学SSM 整合，就配置文件也是边学边敲的。所以出现了很多的错误。本次记录的错误很恶心，就是因为自己的不小心（本来就是不会。。。勿喷）。搞了一天才找到，还是问了别人的。下面将他记录下来。

在这里我错误的是，找不到Dao 然后创建不了 Service 然后就使用不了工厂，然后然后就是一连错。然后在启动的Tomcat的时候风平浪静，但是一访问Controller 的时候注入 Service 的时候就开始错了。

一般错误是在于，你没有注入：少些@Survice 或者 没写@Autowired 然后又或是你的dao层出现问题。但是更多的是你的配置文件错误。mapper 注入出错 。

Service 在创建的时候需要使用Dao 所以它需要找打Dao 然后找到Mapper文件。

我的mapper文件和Dao文件如图

但是我在写配置文件的时候：扫描mapper文件

 

1.  
   <!-- mapper扫描器 -->
2.  
   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
3.  
   <property name="basePackage" value="com.nyist.dao.mapper"></property>
4.  
   <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
5.  
   </bean>

然后找不到Dao 然后就没然后了。死了

 

需要将 

com.nyist.dao.mapper 的mapper 去掉。

 

介绍了解决，下面是错误的描述
