本文详细介绍了如何在SpringBoot项目中正确配置MongoDB，避免常见错误，如使用spring-boot-starter-data-mongodb依赖及在application配置文件中设置正确的连接URI。

springboot集成mongodb, 很多时候还停留在spring xml配置的方式，这样就没有用到
springboot的好处，而且会在配置用户密码时有出现下面类似报错

其实配置mongodb只需要两个配置
引入mongodb包

<dependency>
   <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

application增加配置：

spring.data.mongodb.uri: mongodb://${mongo.username}:${mongo.password}@${mongo.replicaSet}/${mongo.dbName}
