java - 如何在 Spring Boot Restful 中更改大量数据(更新多个数据)

Question

[I want this function to work, i.e. change a lot of data at once][1]

我想一次更改很多数据，怎么办？

这个DAO下只改一个数据，如果要改很多怎么办？

    @PutMapping("/roomstatus/update/{id}")
public ResponseEntity<RoomStatus> updatRoomStatus(@PathVariable(value="id") Integer empid,@Valid @RequestBody RoomStatus RsDetails){

    RoomStatus emp=roomStatusDAO.findOne(empid);
    if(emp==null) {
        return ResponseEntity.notFound().build();
    }

    emp.setRoomNumber(RsDetails.getRoomNumber());
    emp.setFloor(RsDetails.getFloor());
    emp.setGuestName(RsDetails.getGuestName());
    emp.setRoomType(RsDetails.getRoomType());
    emp.setBedType(RsDetails.getBedType());
    emp.setRoomStatus(RsDetails.getRoomStatus());
    emp.setConditions(RsDetails.getConditions());

    RoomStatus updateRoomStatus=roomStatusDAO.save(emp);
    return ResponseEntity.ok().body(updateRoomStatus);                      
}
