SpringBoot中如何集成MongoDB  
1.首先添加maven依赖     
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
        </dependency>

2.添加nongoDB连接配置

spring.application.name=spirngboot-mongodb

spring.data.mongodb.database=admin
spring.data.mongodb.host=127.0.0.1
spring.data.mongodb.password=root
spring.data.mongodb.port=27017
spring.data.mongodb.username=root
