SpringBoot在Controller层接收参数的n种姿势(超详细)

@RestController
@RequestMapping("book")
public class BookController {

    @Resource
    private BookService bookService;
    /**
     * 按照条件获取书籍信息
     * @param bookParams
     * @return
     */
    @GetMapping("/getBookLists")
    @ResponseBody
    public CommonResponse<List<Book>> getBookLists(BookParams bookParams) {
        // 按照查询条件分页查询书籍
        List<Book> books = bookService.getBookList(bookParams);
        CommonResponse response = CommonResponse.successInstance(books);
        return response;
    }
}

  @RequestMapping("/get")
    public void get (@RequestParam(name = "user") String user){
        System.out.println("接收到参数："+user);
        return "接收到参数："+user;
    }

@GetMapping("/path/{user}")
    public String path(@PathVariable(name = "user") String user){
        System.out.println("接收到参数："+user);
        return "接收到参数："+user;
    }

   @PostMapping("/post/same")
    public String same(@RequestBody Users users){
        System.out.println("JSON 接到的："+users.toString());
        return "JSON 接到的："+users.toString();
    }

@PostMapping("/fastJson")
    public String fastJson(@RequestBody JSONObject param){
        System.out.println("JSON :"+param.toJSONString());
        return "JSON :"+param.toJSONString();
    }

@RequestMapping("/sameParamName")
    public String sameParamName(String users , String id){
        System.out.println("users:"+users+"id: "+id);
        return "users:"+users+"id: "+id;
    }
