springboot整合Mongodb
1.增加依赖
注意：springboot其实还是整合的spring-data-mongodb，通过spring-data去操作MongoDB数据库

<!-- springboot整合Mongodb(1) -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

2.配置mongodb连接信息(在application.properties中)

# springboot整合Mongodb(2)
# 验证登录信息的库
spring.data.mongodb.authentication-database=hamsv4_developer
# 要连接使用的库
spring.data.mongodb.database=hamsv4_developer
spring.data.mongodb.host=127.0.0.1
spring.data.mongodb.port=27017
spring.data.mongodb.username=admin
spring.data.mongodb.password=admin

由于我配置了多数据源，因此配置信息放入生产环境配置文件中(application-project.properties)
springboot整合Mongodb
约定的不同的环境下配置文件名称设定

3.定义mongodb接口DAO


```java
package com.steno.propertiestest.dao.mongodbDao;

public interface MongodbDao {
    /**
     * mongodb保存数据
     * @param object
     */
    public void saveMongo(Object object);
}


4.定义mongodb接口DAO的实现类，并注入MongoTemplate操作模板类

```java
package com.steno.propertiestest.dao.mongodbDao.impl;

import com.steno.propertiestest.dao.mongodbDao.MongodbDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.stereotype.Component;

@Component
public class MongodbDaoImpl implements MongodbDao {

    @Autowired
    private MongoTemplate mongoTemplate;

    public void saveMongo(Object object){
        mongoTemplate.save(object);
    }

}

5.定义controller测试

package com.steno.propertiestest.controller;

import com.steno.propertiestest.dao.mongodbDao.MongodbDao;
import com.steno.propertiestest.vo.Book;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MongodbController {

    @Autowired
    private MongodbDao mongodbDao;

    @GetMapping("saveMongo")
    public String saveMongo(){
        Book book = new Book();
        book.setPrice("100");
        book.setAuthor("mongo");
        book.setName("mongodb");
        mongodbDao.saveMongo(book);
        return "新增mongodb数据成功！";
    }

}
