springboot 工程启动报错之Consider defining a bean of type ‘XXX’ in your configuration. 报错Consider defining a bean of type

报错如图：

APPLICATION FAILED TO START Description : Parameter 2 of constructor in com.javasm.service.impl . sales. SalesOrderItemsServiceImp1 required a bean of type ' com.javasm.domin . vo. sales . SalesGoodsVO ' that could not be found. Action : Consider defining a bean of type ' com.javasm.domin . vo. sales . SalesGoodsVO ' in your configuration .

 

解决办法：

其实就是声明的变量没有被springboot注入容器 如图三个变量均进行了声明，均使用了@RequiredArgsConstructor+private final 但VO类其实没能注入容器

-@RequiredArgsConstructor//*0 @Transactiona1 - @Service public class SalesOrderItemsServiceImp1 extends BaseServiceimp1<Sa1esl private final SalesOrderItemsMapper salesOrderItemsMapper; private final SalesOrderItemsTransfer salesOrderItemsTransfer; private final SalesGoodsVO salesGoodsVO;

 

查看mapper接口，被springboot启动类上的注解以包扫描的形式注入了容器，所以没问题

3@SpringBootApp1ication @mapperScan(basePackages .com . mapper " @Enab1eTransactionmanagement// //@Enab1eSchedu1ing/,/ff,É'f-%%ißE public class ProjectApp1ication {

 

查看transfer类，被@Component注解声明，所以也没问题

- @Component - @RequiredArgsConstructor public class SalesOrderItemsTransfer extends Be

 

查看salesGoodsVO类，既没有包扫描，又没有@component注解，自然就报错了

解决办法 要么加上@component，要么自己new对象

private SalesGoodsVO salesGoodsVO new SalesGoodsVO();
