java后端-GET接收参数格式

一、直接接收路径带参

//get请求路径:http:localhost:9090/room/get?id=1
//后端接收:
@GetMapping("/get")
public Room getByIdRoom(Integer id){
        return roomService.getByIdRoom(id);
        }
//        @GetMapping("/get")
//public Room getByIdRoom(@RequestParam Integer id){
//        return roomService.getByIdRoom(id);
        }

二、使用@PathVariable

//get请求路径:http:localhost:9090/room/get/1/xxxx
//后端接收:
@DeleteMapping("/delete/{id}/{room}")
public boolean delete(@PathVariable Integer id,@PathVariable String room){
        return roomService.removeByIdRoom(id);
        }

三、get用实体接收

//使用实体内的字段拼接传递向后端发送请求.实体属性会自动匹配
//get请求路径:http://127.0.0.1:9090/room/get?id=10&room=xxx
//后端接收:
@GetMapping("/get")
public Room getByIdRoom(Room room){
        return roomService.getByIdRoom(room.getId());
        }
