The injection point has the following annotations: - @org.springframework.beans.factory.annotation.Autowired(required=true)

Java报错：

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'com.smartpension.mapper.CommodityCategoryMapper' in your configuration.

错误原因：Autowired 根据类型去spring容器找，找不到那个类，就会报错。

解决方法：在springboot启动类上添加注解 @MapperScan(basePackages)，引号里面代表dao方法

/**
 * 启动程序
 */
@SpringBootApplication
@EnableAspectJAutoProxy
@EnableAsync
@EnableTransactionManagement
@EnableScheduling
@MapperScan("com.smartpension.mapper")
public class SmartPensionServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(SmartPensionServiceApplication.class, args);
    }
}
