1.首先创建一个maven项目:demo-mongodb

2.pom.xml中引入相关的jar包

2.1.由于该项目需要提供controller接口因此引入web的jar包

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

2.2.因为项目是springboot集成mongodb因此需要引入mongodb相关包

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

2.3.另外，为了简化对象的get set方法，引入lombok包

<dependency>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok</artifactId>
    </dependency>

lombok 说明参考

2.4.springboot项目必须引入spring-boot-starter-parent

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.5.RELEASE</version>
  </parent>
  

3.重要类

3.1.启动类的创建

package com.gaoxinfu.demo.mongodb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @Description:
 * @Author: gaoxinfu
 * @Date: 2020-10-22 16:33
 */
@SpringBootApplication
public class DemoMongodbApp {

    public static void main(String[] args) {
        SpringApplication.run(DemoMongodbApp.class,args);
    }
}

3.2.创建对象类

package com.gaoxinfu.demo.mongodb;

import lombok.Data;

/**
 * @Description:
 * @Author: gaoxinfu
 * @Date: 2020-10-22 16:54
 */

@Data
public class Person {

    private String id;

    private String name;

    private Integer age;

    private String sex;

    public Person(String id, String name, Integer age, String sex) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.sex = sex;
    }

    @Override
    public String toString() {
        return "Person{" +
                "id='" + id + '\'' +
                ", name='" + name + '\'' +
                ", age=" + age +
                ", sex='" + sex + '\'' +
                '}';
    }
}

3.3.创建访问入口的HelloController

package com.gaoxinfu.demo.mongodb;

import org.springframework.data.mongodb.core.MongoOperations;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;

/**
 * @Description:
 * @Author: gaoxinfu
 * @Date: 2020-10-22 16:36
 */
@RestController
public class HelloController {

    @Resource
    private MongoOperations mongoOperations;

    @RequestMapping(value = "hello/{name}",method = RequestMethod.GET)
    public String hello(@PathVariable String name){

        Person person=new Person("1",name,18,"man");
        return "HelloController.hello ="+name;
    }

    @RequestMapping(value = "hello/add",method = RequestMethod.GET)
    public String addPerson(){
        Person person=new Person("1","gaoxinfu",18,"man");
//        return "HelloController.hello ="+name;
        mongoOperations.save(person);
        return "保存成功";
    }
}

3.4.配置文件

server.port=8080
spring.data.mongodb.uri=mongodb://localhost:27017/test

3.5.备注：这里假设你已经安装成功mongodb

3.6.验证

3.6.1.页面请求

3.6.2.mongodb变化
