1.问题描述
在Idea的spring工程里,经常会遇到Could not autowire. No beans of 'xxxx' type found的错误提示。但程序的编译和运行都是没有问题的,这个错误提示并不会产生影响。但红色的错误提示在有些有强迫症的程序员眼里,多多少少有些不太舒服。

原因可能有两个,第一个是IntellijIDEA本身工具的问题。第二个便是我们导入@Service包的时候导入包错误造成的
第一种原因,spring auto scan配置,在编辑情况下,无法找不到对应的bean,于是提示找不到对应bean的错误。常见于mybatis的mapper,如下:<!-- mapper scanner configurer --> <bean id="mapperScannerConfig" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.adu.spring_test.mybatis.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean>
- 解决方案
针对第一种原因,解决办法是:降低Autowired检测的级别,error改成warning或其它可以忽略的级别。
