持久层使用通用mapper，service层，为了简化crud，抽取了baseservice,定义了

protect Mapper <T> mapper，当书写的service继承了baseservice的时候，通过自动注入注解注入自己定义的mapper，为什么总是报错，不能注入？

有人遇到过吗？可以帮忙解决下吗

把spring的配置文件发来看一下：

要在spring4中配置mybatismapper：

<spanstyle="color:#FF0000">
  <beanclass="tk.mybatis.spring.mapper.MapperScannerConfigurer">
    <propertyname="basePackage"value="com..mapper"/>
    <propertyname="properties">
      <value>
        mappers=tk.mybatis.mapper.common.Mapper
      </value>
    </property>
  </bean>

790916938你好，你有时间吗？可以加下我的qq帮我看下吗？你好，这个配置文件，我贴上来了，github.abel533是在mybatis配置文件中配置的

<bean
      class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
      <propertyname="systemPropertiesModeName"value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
      <propertyname="ignoreResourceNotFound"value="true"/>
      <propertyname="locations">
         <list>
            <value>classpath:jdbc.properties</value>
            <value>classpath:env.properties</value>
         </list>
      </property>
   </bean>
   <context:component-scanbase-package="com.taotao.manage.service"/>
   <beanid="dataSource"class="com.jolbox.bonecp.BoneCPDataSource"
      destroy-method="close">
      <propertyname="driverClass"value="${jdbc.driver}"/>
      <propertyname="jdbcUrl"value="${jdbc.url}"/>
      <propertyname="username"value="${jdbc.username}"/>
      <propertyname="password"value="${jdbc.password}"/>
      <propertyname="idleConnectionTestPeriod"value="60"/>
      <propertyname="idleMaxAge"value="30"/>
      <propertyname="maxConnectionsPerPartition"value="150"/>
      <propertyname="minConnectionsPerPartition"value="5"/>
   </bean>

持久层配置文件

configuration>
<settings>
   <settingname="mapUnderscoreToCamelCase"value="true"/>
</settings>
<plugins>
   <plugininterceptor="com.github.pagehelper.PageHelper">
       <propertyname="dialect"value="mysql"/>
       <propertyname="rowBoundsWithCount"value="true"/>
   </plugin>
<plugininterceptor="com.github.abel533.mapperhelper.MapperInterceptor">
   <propertyname="IDENTITY"value="MYSQL"/>
   <propertyname="mappers"value="com.github.abel533.mapper.Mapper"/>
</plugin>
</plugins>
</configuration>

持久层配置文件，上面的是mybatis的配置文件

<beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean">
      <propertyname="dataSource"ref="dataSource"/>
      <propertyname="configLocation"value="classpath:mybatis/mybatis-config.xml"/>
        <propertyname="mapperLocations"value="classpath:mybatis/mappers//*.xml"/>
      <propertyname="typeAliasesPackage"value="com.taotao.manage.pojo"/>
   </bean>
    <beanclass="org.mybatis.spring.mapper.MapperScannerConfigurer">
      <propertyname="basePackage"value="com.taotao.manage.mapper"></property>
   </bean>

把

    <beanclass="<spanstyle="color:#FF0000">org.mybatis.spring.mapper.MapperScannerConfigurer">
      <propertyname="basePackage"value="com.taotao.manage.mapper"></property>
   </bean>

改为

<beanclass="<spanstyle="color:#FF0000">tk.mybatis.spring.mapper.MapperScannerConfigurer">
    <propertyname="basePackage"value="com.**.mapper"/>
    <spanstyle="color:#FF0000"><propertyname="properties">
      <value>
        mappers=tk.mybatis.mapper.common.Mapper
      </value>
    </property>
  </bean>

红色的地方都改过来。

这个是哪个包下的？我点不进去，貌似没引入包楼主，在么在的

我也遇到这这个问题，请问楼主怎么解决的？
