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?

把spring的配置文件发来看一下:

要在 spring4中配置mybatis mapper:

<!-- 配置mybatis通用mapper -->
    <bean class="tk.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.**.mapper" />
        <property name="properties">
            <value>
                mappers=tk.mybatis.mapper.common.Mapper
            </value>
        </property>
    </bean>

持久层配置文件,上面的是mybatis的配置文件

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