Spring整合MongoDB3.4

1.首先引入依赖

2.然后进行整合

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
     http://www.springframework.org/schema/context
     http://www.springframework.org/schema/context/spring-context-4.0.xsd
   ">

    <bean id="mongoClientUri" class="com.mongodb.MongoClientURI">
    //用户名:密码@url:端口/数据库名
        <constructor-arg name="uri" value="mongodb://yonhuming:mima@localhost:27017/dataName" />
    </bean>
    <bean id="mongoClient" class="com.mongodb.MongoClient">
        <constructor-arg ref="mongoClientUri"/>
    </bean>
    <bean id="mongoDbFactory" class="org.springframework.data.mongodb.core.SimpleMongoDbFactory">
        <constructor-arg ref="mongoClient"/>
        //数据库名
        <constructor-arg name="databaseName" value="dataName"/>
    </bean>
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg ref="mongoDbFactory"/>
    </bean>
</beans>

3.测试

@Controller
public class MongoDBTest {

    @Autowired
    private MongoTemplate mongoTemplate;


    public void demo() {
        //创建实体类
        MarketKline marketKline = new MarketKline();
        marketKline.setExchangeName("123");
        //插入数据,需要指定数据库表名
        mongoTemplate.insert(marketKline,"表名");
        /**查询*/
        //添加查询条件
        criteria.andOperator(Criteria.where("name").is("张三"),Criteria.where("age").is("18");
                //创建Query实例
                Query query = new Query();
                //根据年龄进行升序排序
                query.with(new Sort(new Order(Direction.ASC,"age")));
                query.addCriteria(criteria);
                //进行查询
                List list = mongoTemplate.find(query, 返回的实体类.getClass(),"数据库表名");

    }
}
