mongodb 表 mogu_attendance 的集合如上：

按照  orgEntity 中的字段比如  schoolId 查询：

mongodb查询如下：

db.getCollection(‘mogu_attendance’).find( { “orgEntity.schoolId” : “f11c8ea12f457dbc19c768a8bb6357f8”,
“orgEntity.classId” : { “$in” : [“5a05540e9fd1ce8604015f3fa5067b63”,
“61a582659385c9b91033bad877609758”, “70ef8baad5d97ae7b77c6df3038b0d84”,
“87108cd7b71775fdf45a220eb734b6be”] },
“$and” : [{ “attendenceTime” : { “$gte” : ISODate(“2018-09-12T06:11:47.000Z”) } },
{ “attendenceTime” : { “$lte” : ISODate(“2029-09-22T06:11:47.000Z”) } }] })

在java实体中，需要把 需要查询的字段如 schoolId 放到实体中：

@Data
public class MoguAttendenceEntity extends BaseEntity implements Serializable {
    private static final long serialVersionUID = 1L;    /**
     * 唯一主键
     */    private String attendanceId;    /**
     * 学校ID
     */
    private String schoolId;    /**
     * 是否补卡
     */
    private Integer isReplace;    private List<MongoGxyPracticeLogDto> logDtoList;
    /**
     * 入参
     */
    private Date startTime;
    private Date endTime;
    private String comment;
    private List<String> attendenceIds;
    private Integer applyState;
    private String teaId;
    private Date dateTime;    private String depId;
    private String majorId;
    private String classId;
    private String userId;
    private Long snowFlakeId;
    /**
     * 筛选天数条件（1 连续3天 2七天 3一个月）
     */
    private Integer dayType;
    /**
     * 表名
     */
    private  String attendencdTabName;
    private String stuTabName;
    private String roleKey;
    private List<String> depIds;
    private List<String> classIds;    /**
     * 考勤时间
     */
    private Date attendenceTime;    private List<MoguAttendenceEntity> attendenceDtos;    private String backup;    private OrgEntity orgEntity;    private String studentId;    private String teacherId;    private String grade;

　　private List<String> classIds;

}

代码如下：

moguAttendenceEntity.setClassIds(getClassIds(request));

public List<MongoMoguAttendenceDto> listAttendance(MoguAttendenceEntity attendenceEntity){
    Sort sort = new Sort(Sort.Direction.ASC,"attendenceTime");
    Query query = new Query();
    Criteria criteria = new Criteria();
    if (attendenceEntity.getCurrPage() != 0 && attendenceEntity.getPageSize() != 0) {
        query.skip((attendenceEntity.getCurrPage()-1)*attendenceEntity.getPageSize())
                .limit(attendenceEntity.getPageSize());
    }
    if(StrUtil.isNotEmpty(attendenceEntity.getDepId())){
        criteria.and("orgEntity.depId").is(attendenceEntity.getDepId());
    }
    if(StrUtil.isNotEmpty(attendenceEntity.getGrade())){
        criteria.and("orgEntity.grade").is(attendenceEntity.getGrade());
    }
    if(StrUtil.isNotEmpty(attendenceEntity.getUsername())){
        criteria.and("orgEntity.userName").is(attendenceEntity.getUsername());
    }
    if(StrUtil.isNotEmpty(attendenceEntity.getStudentNumber())){
        criteria.and("orgEntity.studentNumber").is(attendenceEntity.getStudentNumber());
    }
    if(StrUtil.isNotEmpty(attendenceEntity.getSchoolId())){
        criteria.and("orgEntity.schoolId").is(attendenceEntity.getSchoolId());
    }    if(StrUtil.isNotEmpty(attendenceEntity.getStuId())){
        criteria.and("memberId").is(attendenceEntity.getStuId());
    }    if(attendenceEntity.getDepIds()!=null && attendenceEntity.getDepIds().size()>0 ){
        criteria.and("orgEntity.depId").in(attendenceEntity.getDepIds());
    }    if(attendenceEntity.getClassIds()!=null && attendenceEntity.getClassIds().size()>0 ){
        criteria.and("orgEntity.classId").in(attendenceEntity.getClassIds());
    }    if(attendenceEntity.getTeacherId()!=null  ){
        criteria.and("teacherId").is(attendenceEntity.getTeacherId());
    }    if(!StringUtils.isEmpty(attendenceEntity.getStartTime()) && !StringUtils.isEmpty(attendenceEntity.getEndTime())){
        criteria.andOperator(
                Criteria.where("attendenceTime").gte(attendenceEntity.getStartTime()),
                Criteria.where("attendenceTime").lte(attendenceEntity.getEndTime())
        );
    }    query.addCriteria(criteria);
    query.with(sort);
    List<MongoMoguAttendenceDto> data = mongoTemplate.find(query,MongoMoguAttendenceDto.class);    return data;
}聚合查询：

db.getCollection("mogu_attendance").aggregate(
    [
        {
            "$match" : {
                "attendanceType" : { $exists : false },
                "state" : "NORMAL",
        "$and" : [{ "attendenceTime" : { "$gte" : ISODate("2019-09-15T06:11:47.000Z") } },
                 { "attendenceTime" : { "$lte" : ISODate("2019-09-16T06:11:47.000Z") } }]
            }
        },
        {
            "$group" : {
                "_id" : {
                    "memberId" : "$memberId",
                    "planId" : "$planId",
          "attendenceTime" : "$attendenceTime",
                     "attendanceType" : "$attendanceType",
                    "state" : "$state"
                },
                "COUNT_PID" : {
                    "$sum" : 1.0
                }
            }
        }
    ]
)

mongoDB批量插入：

public int batchsave(List<NoticeSentRecordDto> objeceList){
    template.insert(objeceList,NoticeSentRecordDto.class);
    return 1;
}二 mongodb 模糊查询：按照 orgEntity 下面的 userName 模糊查询，   orgEntity.schoolId 精确查询：

db.getCollection(‘mogu_attendance’).find({ “orgEntity.userName” : { “$regex” : “梦”, “$options” : “” },
“orgEntity.schoolId” : “f11c8ea12f457dbc19c768a8bb6357f8” })

Sort sort = new Sort(Sort.Direction.DESC,”attendenceTime”);
Query query = new Query();
Criteria criteria = new Criteria();
if (attendenceEntity.getCurrPage() != 0 && attendenceEntity.getPageSize() != 0) {
query.skip((attendenceEntity.getCurrPage()-1)*attendenceEntity.getPageSize())
.limit(attendenceEntity.getPageSize());
}
if(StrUtil.isNotEmpty(attendenceEntity.getUsername())){
criteria.and(“orgEntity.userName”).regex(attendenceEntity.getUsername());
}
if(StrUtil.isNotEmpty(attendenceEntity.getSchoolId())){
criteria.and(“orgEntity.schoolId”).is(attendenceEntity.getSchoolId());
}
query.addCriteria(criteria);
query.with(sort);
List<MongoMoguAttendenceDto> data = mongoTemplate.find(query,MongoMoguAttendenceDto.class);

mongodb分页 or 查询：

public List<GxyWarnEntity>  selectWarnPage(GxyWarnEntity  gxyWarnEntity){        Criteria cri =Criteria.where("schoolId").is(gxyWarnEntity.getSchoolId());        if(gxyWarnEntity.getBatchId()!=null) {
            cri.and("batchId").is(gxyWarnEntity.getBatchId());
        }        if(gxyWarnEntity.getStudentName()!=null){
            cri.orOperator(Criteria.where("studentName").regex(gxyWarnEntity.getStudentName()),
                    Criteria.where("teacherName").regex(gxyWarnEntity.getStudentName())            );
        }        Query query = new Query(cri);
        if (gxyWarnEntity.getCurrPage() != null && gxyWarnEntity.getPageSize() != null) {
            query.skip((gxyWarnEntity.getCurrPage()-1)*gxyWarnEntity.getPageSize())
                    .limit(gxyWarnEntity.getPageSize());
        }        return template.find(query, GxyWarnEntity.class);
    }

删除集合：

template.dropCollection(View.class);
