Java mongodb复杂多条件查询

引入依赖

     org.springframework.boot
     spring-boot-starter-data-mongodb

添加配置

spring:
  data:
    mongodb:
      uri: mongodb://admin:[email protected]:27017,192.168.1.102:27017/transfer

使用MongoTemplate

@Resource
private MongoTemplate mongoTemplate;

// 创建查询对象
Query query =new Query();

// 设置分页
query.skip(0); //页码
query.limit(10); //每页显示数量

// 创建复合查询对象
Criteria cri = new Criteria();
// 设置条件（注意：设置查询的值类型必须和mongodb中类型一致）
cri.and("status").is("0");   // 类型为String，类似sql中 status = '0'
cri.and("boolRelation").is(0D);   // 类型为Double，类似sql中 boolRelation = 0
cri.and("enforType").regex("01.*");   // 正则表达匹配，类似右模糊查询，sql中 like '01%'
// 时间段查询
try {
	SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
	cri.and("receiveTime").gte(sdf.parse(“2019-07-01 10:00:00”)).lte(sdf.parse(“2019-07-16 10:00:00”));   
}catch (Exception e){
	e.printStackTrace();
}
// 如果查询条件一个字段要匹配多个值，类似 and (path like '1001%' or path = '1002' or path like '%1003%')
List orgCriList = new ArrayList<>();   // 创建条件集合
// 添加条件
orgCriList.add(Criteria.where("path").regex("1001.*"));
orgCriList.add(Criteria.where("path").is("1002"));
orgCriList.add(Criteria.where("path").regex(".*1003.*"));
Criteria orgCri = new Criteria();
orgCri.orOperator(orgCriList.toArray(new Criteria[orgCriList.size()]));
// 创建一个查询对象，用于存放and和or条件
Criteria criteria = new Criteria();
criteria.andOperator(cri,orgCri);
// 添加到query中
query.addCriteria(criteria);
//设置排序
List orders = new ArrayList<>();
orders.add(new Order(Direction.ASC, "boolRelation"));
orders.add(new Order(Direction.DESC, "receiveTime"));
// 添加到query中
query.with(Sort.by(orders));
/**
 * 最终的查询条件我用oracle sql表示：
 * status = '0'
 * and boolRelation = 0
 * and enforType like '01%'
 * and receiveTime>=to_date('2019-07-01 10:00:00','yyyy-mm-dd hh24:mi:ss')
 * and receiveTime>=to_date('2019-07-01 10:00:00','yyyy-mm-dd hh24:mi:ss')
 * and (path like '1001%' or path = '1002' or path like '%1003%')
 * order by boolRelation, receiveTime desc
 */

// 统计总数
long count = mongoTemplate.count(query, EnforModel.class);
// 查询返回记录
List records = mongoTemplate.find(query, EnforModel.class);

例子中用到的实体类

package com.js.enfor.manage.model;

import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.experimental.Accessors;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

import java.io.Serializable;
import java.util.Date;

/**
 * 

 * @author ycq
 * @since 2019-07-16
 */
@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
@Document(collection = "JS_ENFOR_DATA")
public class EnforModel implements Serializable {

    private static final long serialVersionUID = 1L;
    
    /**
     * 主键
     */
    @Id
	private String id;

	/**
	 * 类型
	 */
	private String enforType;
	
	/**
	 * 接收时间
	 */
	private Date receiveTime;

	/**
	 * 是否已关联
	 */
	private Double boolRelation;
	
	/**
	 * 状态
	 */
	private String status;
	
	/**
	 * 关联时间

	private Date relationTime;
	
	/**
	 * path

	private String path;
	
}
