配置【MapperScannerConfigurer】提示【SqlSessionFactory to use in the case that there is more than one in the spring context.】

在配置MapperScannerConfigurer的时候一直提示我如下信息，虽然不影响代码运行但是看着很烦，仔细看提示信息才发现，它再说如果只有一个数据源的话你不需要配置SqlSessionFactory。所以把提示报差的那航配置文件注释掉就好了。

错误原文：

Specifies which SqlSessionFactory to use in the case that there is more than one in the spring context. Usually this is only needed when you 
have more than one datasource. Note bean names are used, not bean references. This is because the scanner loads early during the 
start process and it is too early to build mybatis object instances.

 

【我的配置文件】

　　 <!-- 使用自动扫描创建mapper bean -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.lcy.mapper" />
        <property name="SqlSessionFactoryBeanName" value="SqlSessionFactory" />
        <property name="annotationClass" value="org.springframework.stereotype.Repository" />
    </bean>

 

【正确的配置文件】

 <!-- 使用自动扫描创建mapper bean -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.lcy.mapper" />
        <property name="annotationClass" value="org.springframework.stereotype.Repository" />
    </bean>
