Question

我想通过Thymeleaf更新密码。到目前为止，一切正常，除了调用更新方法后，我会收到一条错误消息。

这是我的代码：

@PostMapping
public String updateOldPassword(@Valid @ModelAttribute("password") PasswordChange userAndpassword,
            BindingResult result, ModelMap model) {

    if (result.hasErrors()) {
        return "error";
    }

    String username = userAndpassword.getUsername();
    String password = userAndpassword.getPassword();

    String newPassword = passwordEncoder.encode(password);

    passwordRepo.updatePassword(username, newPassword);
    return "redirect:/";
}

public interface updateOldPasswordRepository extends JpaRepository<Benutzer, Long>{
    @Modifying
    @Query(value = "UPDATE benutzer SET passwort = ? WHERE benutzername = ?", nativeQuery = true)
    void updatePassword(String benutzername, String passwort);
}

当它尝试更新密码时，出现以下错误消息：

ERROR o.a.c.c.C.[.[.[.[dispatcherServlet] - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query] with root cause

也许有人可以帮助我。

谢谢。

我发现了问题。我不得不使用

@Transactional

也是。

这是完整的代码：

public interface updateOldPasswordRepository extends JpaRepository<Benutzer, Long>{
    @Modifying
    @Query(value = "UPDATE benutzer SET passwort = :passwort WHERE benutzername = :benutzername", nativeQuery = true)
    @Transactional
    void updatePassword(@Param("benutzername") String benutzername, @Param("passwort") String passwort);
}

在Spring Boot Thymeleaf中更新密码
