1.导入相关jar

        </dependency>
    </dependencies>

2.创建spring-mongo配置文件

 <!--连接mongodb-->
    <mongo:mongo id="mongo" host="127.0.0.1" port="27017"></mongo:mongo>

<!-- mongoTemplate 对mongo一个封装 ，通过构造器注入-->
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg ref="mongo"></constructor-arg>
        <constructor-arg name="databaseName" value="数据库名"></constructor-arg>
    </bean>

3.创建实体类

@Data
@AllArgsConstructor
@NoArgsConstructor
@Document       //代表mongodb的实体
public class Car {

    @Id //主键
    private String id;

    private String name;

    private Date time;

}

4.创建测试类（保存方法）

第一种方式：spring整各Junit测试

相关代码：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring-mongo.xml")
public class MongoTest{

   @Autowired
    private MongoTemplate mongoTemplate;


    @Test
    public void test1(){
        Car c = new Car();
        c.setName("布加迪威龙");
        c.setTime(new Date());
        mongoTemplate.save(c);
    }

第二种方式

相关代码：

public class MongoTest{

    private MongoTemplate mongoTemplate;


    @Before
    public void before(){
    ClassPathXmlApplicationContext mo = new ClassPathXmlApplicationContext("classpath:spring-mongo.xml");
        mongoTemplate=(MongoTemplate) mo.getBean("mongoTemplate");
    }


    @Test
    public void test2(){
        Car a = new Car();
        a.setName("法拉利");
        a.setTime(new Date());
        a.setPrice(78);
        mongoTemplate.save(a);
    }

5.查询所有

6.条件查询

• Query导包
  
• 单查询相关代码：

/**
     * 单条件查询
     */
    @Test
    public void test4(){
        Query query = new Query();
        Criteria where = new Criteria();
       /* where.and("price").lt(78); //查询价格小于78
        where.and("price").is(78);//查询价格是78*/
        where.and("price").lte(78);//查询小于等于78
        query.addCriteria(where);
        List<Car> cars = mongoTemplate.find(query, Car.class);
        System.out.println(cars);
    }

• 多条件查询代码：

 /**
     * 多条件查询
     */
    @Test
    public void test5(){
        Query query = new Query();
        Criteria where1= new Criteria();
        where1.and("price").lte(78);
        Criteria where2= new Criteria();
        where2.and("price").gte(50);
        query.addCriteria(new Criteria().andOperator(where1,where2));
        List<Car> cars = mongoTemplate.find(query, Car.class);
        System.out.println(cars);
    }

• 分页

 /**
     * 分页查询
     */
    @Test
    public void test6(){
        int page=1; //当前页
        int rows=3; //每页条数
        Query query = new Query();
        query.skip((page-1)*rows).limit(rows);
        List<Car> cars = mongoTemplate.find(query, Car.class);
        System.out.println(cars);
    }

7.修改

/**
     * 修改
     */
    @Test
    public void test7(){
        Query query = new Query();
        Criteria where = new Criteria();
        where.and("price").is(100);
        query.addCriteria(where);
        Update update = new Update();
        update.set("price",10);
        mongoTemplate.updateFirst(query,update,Car.class); //修改第一条符合的数据
       // mongoTemplate.updateMulti(query,update,Car.class);//修改所有符合的数据

    }

8.删除

 /**
     * 删除
     */
    @Test
    public void test8(){
        Query query = new Query();
        Criteria where = new Criteria();
        where.and("price").is(10);
        query.addCriteria(where);
        mongoTemplate.remove(query,Car.class);
    }
