[编程]-defined in null, could not be registered
之前已定义:
public interface AntiForgeCodeRepository extends MongoRepository<AntiForgeCode, String> {
}
程序启动、使用该接口正常。
再加一个存mongo的文档类型, 相应多了个接口:
public interface AntiForgeCodeCheckRecordRepository extends MongoRepository<AntiForgeCodeCheckRecord, String> {
}
结果程序启动报错:

原因分析:
The bean 'antiForgeCodeCheckRecordRepository', defined in null, could not be registered. A bean with that name has already been defined in null and overriding is disabled.
这句关键报错，是说antiForgeCodeCheckRecordRepository被定义了两次。
但是代码里其实只有一个地方定义。
也可能是说MongoRepositoryFactoryBean被定义了两次，具体待查:
There is already [Root bean: class [org.springframework.data.mongodb.repository.support.MongoRepositoryFactoryBean];
解决:
spring.main.allow-bean-definition-overriding=true
如果项目里有多个工程，多个配置文件，这个设置就需要找对地方。
一般是住工程那个配置，具体看tomact报错指向那个工程的Application, 比如这里的是DevApplication。
