我向我的控制器添加了一個 put 方法。但是當我訪問它時，出現錯誤 405（方法不允許）。在控制臺中，列印了不支持請求方法“PUT”的錯誤。我有一個 put 正在作業的其他控制器。
我會提供一些幫助。
請求控制器
@RestController
@RequestMapping("/mainsite")
public class MainsiteController {
private MainsiteService mainsiteService;
@Autowired
public MainsiteController(MainsiteService mainsiteService) {
this.mainsiteService = mainsiteService;
}
@PutMapping("{id}")
public Mainsite updateMainsite(@PathVariable("id") Long id, @RequestBody Mainsite mainsite) {
return mainsiteService.updateMainsite(id, mainsite);
}
}

您正在發送請求引數，如上面的日志“/api/v1/mainsite?id=1”所示。
但是您在代碼中使用 PathVariable：
public Mainsite updateMainsite(@PathVariable("id") Long id, @RequestBody Mainsite mainsite) {
您應該將網址發送為“/api/v1/mainsite/1”
