绘制一个用于jhipster生成代码的jdl图，实体包括教师，学生，管理员，实验室，预约，信息，学生教师可以对实验室进行预约，管理员可以审核预约，此外在实验室页面可以对实验室进行查找，

以下是对应的JDL图：

// 定义实体
entity Teacher {
    name String required,
    age Integer,
    gender String
}

entity Student {
    name String required,
    age Integer,
    gender String
}

entity Admin {
    name String required,
    age Integer,
    gender String
}

entity Lab {
    name String required,
    capacity Integer,
    location String
}

entity Reservation {
    startTime LocalDate,
    endTime LocalDate,
    status String
}

entity Message {
    content String,
    createTime ZonedDateTime
}

// 定义实体之间的关系
relationship ManyToMany {
    Teacher{reserved} to Lab{reservedBy},
    Student{reserved} to Lab{reservedBy}
}

relationship OneToMany {
    Admin{audit} to Reservation{auditedBy}
}

relationship ManyToOne {
    Reservation{belongsTo} to Student,
    Reservation{belongsTo} to Teacher
}

// 定义枚举类型
enum ReservationStatus {
    PENDING, APPROVED, REJECTED
}

// 定义DTO
dto ReservationDTO {
    startTime LocalDate,
    endTime LocalDate,
    status ReservationStatus
}

dto LabDTO {
    name String,
    capacity Integer,
    location String
}

// 定义服务
service ReservationService {
    createReservation(reservationDTO: ReservationDTO) : ReservationDTO
    getReservation(id: Long) : ReservationDTO
    updateReservation(reservationDTO: ReservationDTO) : ReservationDTO
    deleteReservation(id: Long)
}

service LabService {
    createLab(labDTO: LabDTO) : LabDTO
    getLab(id: Long) : LabDTO
    updateLab(labDTO: LabDTO) : LabDTO
    deleteLab(id: Long)
}

// 定义过滤器
filter ReservationFilter {
    status String,
    labId Long
}

filter LabFilter {
    name String,
    location String
}

// 定义分页器
paginate Reservation, Lab with pagination
