springboot连接mongodb多条件查询

话不多说 直接上代码

model层 实体类映射 注意不要导错包

import lombok.Getter;
import lombok.Setter;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
import org.springframework.data.mongodb.core.mapping.Field;

import java.io.Serializable;
import java.util.List;

/**

• Created by DELL on 2019/11/26 17:10
  */
  @Document(collection = “store”) //指定mongodb中的一个集合 store就是集合名字
  @Getter
  @Setter
  public class Store implements Serializable {
  // @Id
  // private String id;
  @Field(“storelist.area”)
  private String area;
  @Field(“city”)
  private String city;
  @Field(“storelist.tcList”) //list类型 下面对 tcList字段映射
  public List tcList;

}

import lombok.*;
import org.springframework.data.mongodb.core.mapping.Document;
import org.springframework.data.mongodb.core.mapping.Field;
import org.springframework.stereotype.Service;

import java.util.List;

/**

• Created by DELL on 2019/11/29 14:28
  */
  @Setter
  @Getter
  public class TcList {
  private String xuzhi;
  private String image;
  private String name;
  // private List xiangqing;
  private String price;
  // private List shanghu;
  private String yishou;
  private String disCount;
  private String stroePrice;
  //private String id;

}

servce层 注意不要导错包！

import com.haozhuo.datag.model.Store;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;
import java.util.List;

/**

• Created by DELL on 2019/11/27 11:34
  */
  @Component
  public class StoreService {
  public static final String COLLECTION_NAME = “store”; //指定集合名字

  @Autowired
  private MongoTemplate mongoTemplate;

  public List get(String city,String area,String land){
  Query query = Query.query(Criteria.where(“city”).is(city).and(“storelist.area”).is(area).and(“storelist.land”).is(land)); //条件之间用 and连接
  List store = mongoTemplate.find(query, Store.class, “store”);
  int size = store.size();
  System.out.println(size);
  return store;
  }
  }

Controller层

import com.haozhuo.datag.model.Store;
import com.haozhuo.datag.service.StoreService;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.web.bind.annotation.*;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import java.util.List;

/**

• Created by DELL on 2019/11/27 11:17
  */
  @RestController
  @RequestMapping(value = “store”)
  @EnableSwagger2
  public class Contro {

  @Autowired
  private StoreService storeService;

  @GetMapping("/find")
  @ApiOperation(value = “套餐查询”, notes = " city:城市; area:区;land:路")
  public List getAll(@RequestParam(value = “city”,defaultValue = “北京”) String city,
  @RequestParam(value = “area”,defaultValue = “北京”) String area,
  @RequestParam(value=“land”,defaultValue = “北京”) String land){
  return storeService.get(city,area,land);
  }

}

下面是 pom里 需要的依赖

        org.springframework.boot
        spring-boot-starter-data-mongodb
    
    
        org.mongodb
        mongodb-driver
        3.6.4
    

 
        org.springframework.boot
        spring-boot-starter-web
    
  

    
        com.querydsl
        querydsl-core
        4.2.1
    

yml配置

   spring：
			data:
			    mongodb:
			      database: xxx  //需要查询的数据库名字
			      uri: mongodb://admin:password@需要连接的服务器地址:27017
			      authentication-database: admin  //momgo的库名

到此就完毕了！
