Question

我正在学习spring boot并编写一个小型项目表格。我在构思中运行它并提交表单，注册工作正常，但是当我试图添加新消息时，浏览器就会出现

禁止

我试图添加一个新功能，我希望它也显示用户名，但是不起作用

这是一个Message类

There was an unexpected error (type=Forbidden, status=403).

控制器

@Entity
public class Message {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;

    private String text;
    private String tag;

    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "user_id")
    private User author;


    public Message() {
    }

    public Message(String text, String tag, User user) {
        this.author=user;
        this.text = text;
        this.tag = tag;
    }

    public String getAuthorName(){
        return author !=null ? author.getUsername() : "<nine>";
    }

    public User getAuthor() {
        return author;
    }

    public void setAuthor(User author) {
        this.author = author;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

    public String getTag() {
        return tag;
    }

    public void setTag(String tag) {
        this.tag = tag;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }
}

和html文档

@Controller
public class MainController {

    @Autowired
    private MessasgeRepo messasgeRepo;

    @GetMapping("/")
    public String greeting(Model model) {

        return "greeting";
    }

    @GetMapping("/main")
    public String main(Model model){
        Iterable<Message> messages = messasgeRepo.findAll();
        model.addAttribute("mess",messages);
        return "main";
    }

    @PostMapping("/main")
    public String add (@AuthenticationPrincipal User user,
                       @RequestParam String text,
                       @RequestParam String tag, Model model){
        Message message =new Message(text, tag, user);
        messasgeRepo.save(message);
        Iterable<Message> messages = messasgeRepo.findAll();
        model.addAttribute("mess",messages);
        return "main";
    }

    @PostMapping("filter")
    public String filter(@RequestParam String text, Model model){
        Iterable<Message> messages;
        if(text!=null && !text.isEmpty()) {
            messages = messasgeRepo.findByTag(text);
        }else {
            messages = messasgeRepo.findAll();
        }
        model.addAttribute("mess", messages);
        return "main";
    }
}

Answer 1

我认为此处缺少动作action="/main"，请尝试以下代码

<form method="post" action="/main">
<input type="text"  name="text" placeholder="Enter first name">
<input type="text" name="tag" placeholder="Enter first name">
<button type="submit" class="btn btn-success"> Add order </button>
</form>

提交添加新消息时出现错误403
