Spring 引导，thymeleaf @PostMapping 405 错误信息

Question

I am new here and also new in java programing.我是新来的，也是 java 编程的新手。 I've been strugling second day now with @PostMapping in spring boot MVC.第二天，我一直在为 spring 引导 MVC 中的 @PostMapping 苦苦挣扎。 I can;t understand what's wrong with my code.我无法理解我的代码有什么问题。 I'm working on very simple bank account project.我正在从事非常简单的银行账户项目。

I can't find out whats wrong with connecting @PostMapping in AccountController in execute deposit method, and with thymeleaf form, which should add amount of deposit to account ballance.我无法找出在执行存款方法中连接 AccountController 中的 @PostMapping 以及 thymeleaf 表格有什么问题，这应该将存款金额添加到账户余额中。 I'm just started learning spring so please be gentle:)我刚开始学习 spring 所以请温柔一点:)

`@Controller
public class AccountController {

    @Autowired
    private AccountService accountService;

    private AccountRepository accountRepository;

    // display all accounts
    @AliasFor(value = "accounts")
    @GetMapping("/accounts")
    public String showAccountsList(Model model) {
        List<Account> listAccounts = accountService.listAll();
        model.addAttribute("listAccounts", listAccounts);
        return "accounts";
    }

    @Autowired
    public AccountController(AccountService accountService) {
        this.accountService = accountService;
    }

    //get Account by Id
    @GetMapping("accounts/{id}")
    public ResponseEntity<Account> getAccountById(@PathVariable Long id) {
        Account account = accountRepository.findById(id).orElseThrow(() -> new IllegalArgumentException("Account with id: " + id + " does not exist"));
        return ResponseEntity.ok(account);
    }

Answer 1

You should have csrf token in your form.您的表单中应该有 csrf 令牌。 Put below code before form closing tag.将下面的代码放在表单结束标记之前。

<input 
  type="hidden" 
  th:name="${_csrf.parameterName}" 
  th:value="${_csrf.token}" />
