web 项目是 springboot+mybatis 里面有一个 listener 文件和 mapper 文件如下
listener 文件:
@Component public class InitColorListener implements ApplicationListener { @Resource(name="colorMapper") private ColorMapper mapper; ... } mapper 文件
@Repository("colorMapper") public interface ColorMapper { List<Color> findAll(); ... } 项目编译启动,出现错误:
2017-09-14 11:42:40.298 WARN 3560 --- [ main] o.s.boot.SpringApplication : Error handling failed (Error creating bean with name 'InitColorListener': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'colorMapper' available) 2017-09-14 11:42:40.388 ERROR 3560 --- [ main] o.s.b.d.LoggingFailureAnalysisReporter : Disconnected from the target VM, address: '127.0.0.1:50302', transport: 'socket' A component required a bean named 'colorMapper' that could not be found.
