@PostMapping注解的方法在PostMan中访问报错Method Not Allowed

问题遇到的现象和发生背景

@PostMapping注解的方法在PostMan中访问报错Method Not Allowed

用代码块功能插入代码，请勿粘贴截图

@RestController
@RequestMapping("/test")
public class TestController {
    @Autowired
    private UserService userService;

    @PostMapping (value = "/saveUsers")
    public R saveUsers() {
        User user1 =new User();
        user1.setId("111");
        user1.setUsername("111");
        user1.setPassword("111111");
        user1.setEmail("111@111.com");
        User user2 =new User();
        user2.setId("222");
        user2.setUsername("222");
        user2.setPassword("222222");
        user2.setEmail("222@222.com");
        List userList=new ArrayList<>();
        userList.add(user1);
        userList.add(user2);
        Boolean boo=userService.saveUserList(userList);
        return R.build(Status.SUCCESS,boo);
    }
}

运行结果及报错内容

{
"timestamp": "2022-11-18T07:29:25.593+00:00",
"status": 405,
"error": "Method Not Allowed",
"path": "/test/saveUsers"
}

我的解答思路和尝试过的方法

我将@PostMapping 改为@GetMapping 就能成功

把这里改成post就好
