解决SpringBoot 整合 MongoDB，继承MongoRepository的Repo接口无法注入异常

Posted 2022-11-13 星丶空LTL

报错信息如下：

---

APPLICATION FAILED TO START

---

Description:

Parameter 0 of constructor in com.service.TrackRecordService required a bean of type ‘com.mongo.TrackRecordRepo’ that could not be found.

Action:

Consider defining a bean of type ‘com.mongo.TrackRecordRepo’ in your configuration.

Process finished with exit code 1

TrackRecordRepo是一个接口继承了MongoRepository，同时也使用了@Repository进行注入，编码阶段无报错，但运行起来就报以上报错，显示spring扫描不到，找不到相关的bean。

解决办法：
在@SpringBootApplication主类加上@EnableMongoRepositories注解，让spring扫描mongo相关的类

@SpringBootApplication
@EnableMongoRepositories(basePackages = ["com.mongo"])
