Parameter 0 of method orderSqlSessionFactory in com.config.MultipleDBConfig required a single bean, but 2 were found: - orderDataSource: defined by method 'orderDataSource' in class path resource [com/config/MultipleDBConfig.class] - crmDataSource: defined by method 'crmDataSource' in class path resource [com/config/MultipleDBConfig.class] Action: Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

坑：以上方式链接多数据源时，

在springboot1.x时 datasource上要在一个写数据源上标记@Primary为主数据源

而在springboot2.X时则不需要
