解决spring mybatis 整合后mapper接口注入失败
2024-05-05 12:54:49
spring整合mybatis，在dao层我们只写一个接口，配置相应的*mapper.xml文件，
报如下错误：
1 org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'helloController': Unsatisfied dependency expressed through field 'helloService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'helloService': Unsatisfied dependency expressed through field 'helloMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.aopeng.quest.dao.IHelloMapper' available: expected at least 1 bean which qualifies as autowire candidate.

1 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 2 <property name="basePackage" value="com.xxx.xxx.dao.**.*" /> 3 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> 4 </bean>
basePackage的value应该是指定包名，而我指定的文件名。
改成如下配置，编译正常通过：
1 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 2 <property name="basePackage" value="com.xxx.xxx.dao" /> 3 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> 4 </bean>
