axios请求415错误Uncaught (in promise) Error: Request failed with status code 415

Uncaught (in promise) Error: Request failed with status code 415

错误如下图

前端代码（vue）：

var data = {
            username: this.loginForm.username,
            password: this.loginForm.password
          }
          this.$axios.post(this.GLOBAL.host + '/login', this.$qs.stringify(data)
          ).then(res => {
            // Determine the login status based on the returned results
            console.log(res)
          })

后台代码（springboot）：

@Controller
public class LoginController {

    @Autowired
    private LoginService loginService;

    @RequestMapping(value = "/login",method = RequestMethod.POST)
    @ResponseBody
    public Object login(@RequestBody UserDTO userDTO){
        return loginService.login(userDTO.getUsername(),userDTO.getPassword());
    }
}

错误原因：

当我们使用application / x-www-form-urlencoded时，Spring并不将其理解为RequestBody。因此，如果我们想要使用它，我们必须删除@RequestBody注释。

然后尝试以下方法：
修改LoginController代码：

@Controller
public class LoginController {

    @Autowired
    private LoginService loginService;

    @RequestMapping(value = "/login",method = RequestMethod.POST,
            consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE,
            produces = {MediaType.APPLICATION_ATOM_XML_VALUE, MediaType.APPLICATION_JSON_VALUE})
    @ResponseBody
    public Object login(UserDTO userDTO){
        return loginService.login(userDTO.getUsername(),userDTO.getPassword());
    }
}

重新试一下~~访问成功，问题解决啦
