1：build.gradle 添加mongodb依赖

dependencies {    compile('org.springframework.boot:spring-boot-starter-web')    compile('org.springframework.boot:spring-boot-starter-data-mongodb')    compile group: 'org.mongodb', name: 'mongo-java-driver', version: '3.4.2'    testCompile('org.springframework.boot:spring-boot-starter-test')}

2：启动本地mongdb服务

D:\MongoDB\Server\3.4\bin>mongod --config "D:\MongoDB\Server\3.4\mongo.conf" --auth

3：配置application.properties文件

#mongodb configspring.data.mongodb.host=127.0.0.1spring.data.mongodb.port=27017spring.data.mongodb.username=gwzhspring.data.mongodb.password=gwzhspring.data.mongodb.database=gwzhspring.data.mongodb.authentication-database=gwzh#server configserver.port=9001

4：代码

（1）UserVo.java

package com.example.user;import org.springframework.data.annotation.Id;/** * Created by yan on 2017/4/25. */public class UserVo {    @Id    private String userid;    private String username;    private Integer age;    public String getUserid() {        return userid;    }    public void setUserid(String userid) {        this.userid = userid;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public Integer getAge() {        return age;    }    public void setAge(Integer age) {        this.age = age;    }}

（2）UserRepository.java

package com.example.user;import org.springframework.data.mongodb.repository.MongoRepository;/** * Created by yan on 2017/4/25. */public interface UserRepository extends MongoRepository
     
       {    UserVo findByUserid(String userid);}
     

（3）UserCtrl.java

package com.example.user;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RestController;import java.util.List;/** * Created by yan on 2017/4/25. */@RestController@RequestMapping(        value = "/user",        produces = "application/json;charset=utf-8",        headers = "Accept=application/json")public class UserCtrl {    @Autowired    UserRepository userRepository;    @RequestMapping(            value = "/add",            method = RequestMethod.POST    )    public UserVo addUser(@RequestBody UserVo vo){        return userRepository.save(vo);    }    @RequestMapping(            value = "/list",            method = RequestMethod.GET    )    public List
     
       getUsers(){        return userRepository.findAll();    }    @RequestMapping(            value = "/delete",            method = RequestMethod.POST    )    public boolean deleteUser(@RequestBody UserVo vo){        userRepository.delete(vo.getUserid());        return true;    }}
