Answer 6

看下面回复，必须配置mappers

Answer 7

<!-- 定义Mapper接口扫描-->
<bean class="tk.mybatis.spring.mapper.MapperScannerConfigurer"> 
    <property name="basePackage" value="com.metter.**.mapper"/>
</bean>

这个配置不完整，必须配置mappers，你看看文档。

Answer 10

mapper3.3.4  使用 tk.mybatis.spring.mapper.MapperScannerConfigurer扫描， mapper始终

不能被注入进来 

@Liuzh_533

Answer 11

我要从3.0.0升级到3.3.4，原来spring配置文件中有这么一段：

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="multipleDataSource" />

<property name="plugins">

<array>

<bean class="com.github.pagehelper.PageHelper">

<property name="properties">

<value>

reasonable=true

</value>

</property>

</bean>

<bean class="com.github.abel533.mapperhelper.MapperInterceptor">

<property name="properties">

<value>

mappers=com.github.abel533.mapper.Mapper

notEmpty=true

</value>

</property>

</bean>

</array>

</property>

</bean>

请问，现在<bean class="com.github.abel533.mapperhelper.MapperInterceptor">这一段要怎么配置呢？

Answer 12

@Liuzh_533 ，你的"tk.mybatis.spring.mapper.MapperScannerConfigurer"类有问题

maven打包出来运行报错：

Answer 13

我的问题原来也是这个原因，多谢了

Answer 14

@Liuzh_533 ,按照你的升级说明配置，OK了！

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">改成了

<bean class="tk.mybatis.spring.mapper.MapperScannerConfigurer">

这2个类太像了，原来没看仔细，谢谢！

Answer 15

看看升级日志。

Answer 16

没有按照文档进行配置。

Answer 17

@Liuzh_533 ，我从老的mapper2.3升级到3.3后报这个错误，是哪里配置问题吗？
