Error starting ApplicationContext. To display the conditions report re-run your application with ‘debug’ enabled. 2019-07-31 15:33:15.798 ERROR 14420 — [ main] o.s.b.d.LoggingFailureAnalysisReporter :
APPLICATION FAILED TO START
Description:
Field idWorker in com.example.springbootmybatis.controller.TeacherController required a bean of type ‘com.aspire.commons.autoid.IdWorker’ that could not be found.
The injection point has the following annotations: - @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type ‘com.aspire.commons.autoid.IdWorker’ in your configuration.
同时注入报红 1、Idea设置为警告，或者降低检测级别@Autowired(required = false)
2、更改@Autowired为@Resource 3、在服务层加上注解@Service或
在mapper接口类上加上@Repository或@Component标签
确保包导入正确，@Service正确导入的是import org.springframework.stereotype.Service; 4、启动类放在所有类外层，保证能扫描到所有子包。或者在启动类上添加扫描路径
@ComponentScan(basePackages = {“com.xxx”})
@ComponentScan(basePackageClasses= XXXController.class)
@SpringBootApplication(scanBasePackages={“com.xxx”})
5、在启动类中配置@Bean，或者在引用类上添加@Bean注解
在一个配置类中定义这个类，即可正确修复。 @Bean public IdWorker idWorker() { return new IdWorker(); }
6、mapper接口提示：Could not autowire. No beans of ‘XXXMapper’ type found.
使用到mapper的类序列化，即实现Serializable 接口即可 每个Mapper类中添加 @Mapper
在application.java启动类前面加上 @MapperScan（），参数为dao层包的路径
