推荐答案
您正在尝试使用数据库，但是尚未向Spring Boot提供任何相关信息来连接数据库. Spring Boot 1.3.x不支持Mongo 3.x，您需要先升级到Spring Boot 1.4
You are attempting to use a database but you haven't provided any relevant information to Spring Boot to connect to it. Spring Boot 1.3.x does not support Mongo 3.x, you need to upgrade to Spring Boot 1.4 first
