mongo与spring集合

1、加入lib包，在Maven中

　　　　　<dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-commons</artifactId>
            <version>1.5..RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-mongodb</artifactId>
            <version>1.4..RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongo-java-driver</artifactId>
            <version>2.12.</version>
        </dependency>

2、在Spring的配置文件中，加入如下的命名空间

xmlns:mongo=http://www.springframework.org/schema/data/mongo
对应的location是：http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.5.xsd

3、Bean配置

<mongo:mongo host="192.168.174.104" port=""></mongo:mongo>
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
         <constructor-arg ref="mongo"/>
         <constructor-arg name="databaseName" value="arch1"/>
    </bean> 

4、简单示例

@Repository
public class GoodsMongoDao implements GoodsDAO {

    @Autowired
    private MongoTemplate mongoTemplate;

    private final String COLLEC_NAME = "goods";

    //增加
    public void create(GoodsModel m) {
        mongoTemplate.insert(m, COLLEC_NAME);
    }

    //修改
    public void update(GoodsModel m) {

        DBCollection goods = mongoTemplate.getCollection(COLLEC_NAME);

        BasicDBObject query = new BasicDBObject("uuid", m.getUuid());

        BasicDBObject one = new BasicDBObject().append("uuid", m.getUuid())
                .append("name", m.getName()).append("imgPath", m.getImgPath())
                .append("description", m.getDescription());

        goods.update(query, one);

    }

    //删除
    public void delete(Integer uuid) {
        Criteria query = new Criteria("uuid").is(uuid);

        mongoTemplate.remove(new Query(query), COLLEC_NAME);

    }

    //查询
    public GoodsModel getByUuid(Integer uuid) {

        Criteria query = new Criteria("uuid").is(uuid);

        return mongoTemplate.findOne(new Query(query), GoodsModel.class,
                COLLEC_NAME);

    }

    public List<GoodsQueryModel> getByConditionPage(GoodsQueryModel qm) {

        return null;
    }

    //分页查询
    public List<GoodsQueryModel> getByCondition(GoodsQueryModel qm) {

        Criteria criteria = new Criteria();
        if (StringUtils.isNotEmpty(qm.getName())){
            criteria.andOperator(new Criteria("name").regex(qm.getName()));
        }

        if (StringUtils.isNotEmpty(qm.getName())){
            criteria.andOperator(new Criteria("imgPath").regex(qm.getName()));
        }

        if (StringUtils.isNotEmpty(qm.getName())){
            criteria.andOperator(new Criteria("description").regex(qm.getName()));
        }

        Long count=mongoTemplate.count(new Query(criteria), COLLEC_NAME);

        Page page=qm.getPage();
        page.setTotalCount(count.intValue());

        List<GoodsQueryModel> results=mongoTemplate.find(new Query(criteria).skip(page.getStart()).limit(page.getPageShow()), GoodsQueryModel.class, COLLEC_NAME);

        return results;
    }

}
