这是非常奇怪的，当我在表单标签中的第：action和method属性时，它会给我异常，但是当我从表单标签中删除method属性时，却没有异常发生。

  1. <form id="deliveryAddressForm" action="#" th:action="@{/product/save-address}" method="post" th:object="${address}">

字符串

发生例外状况

  1. <form id="deliveryAddressForm" action="#" th:action="@{/product/save-address}" th:object="${address}">

型

删除method=“post”后无异常

我不明白它为什么会这样。

请查看下面随附的代码

  1. Html代码
  1. <form id="deliveryAddressForm" action="#" th:action="@{/product/save-address}" method="post" th:object="${address}">

SO上有多个问题解释了类似的问题，但除了这个答案here外，大多数问题都没有答案。
我在我的案例中进一步检查了这个问题，每次JSESSIONID没有手动设置或修改时，都会出现这个错误。
我做了一些小实验来弄清楚在什么情况下这个问题会消失：
1.使用会话创建策略ALWAYS可以通过始终生成会话来解决问题。

  1. .and()
  2.         .sessionManagement()
  3.         .sessionCreationPolicy(SessionCreationPolicy.ALWAYS)

字符串
1.使用csrf token repository（如Spring Security Issue 3906中所述）也有助于通过急切地创建csrf token来持久化csrf token（而不使用惰性持久化）。也可以使用CookieCsrfTokenRepository。

  1. .csrf()
  2.         .csrfTokenRepository(new HttpSessionCsrfTokenRepository())

型
对于匿名用户，应用程序仅在需要时生成会话，因此，在呈现表单时请求CSRF令牌可能会在某些情况下导致此问题，例如在长html文件中延迟呈现表单。

基于@sbsatter的回答，我设法解决了我的问题。由于一些depricated标志，我不得不修改代码。对于Sping Boot 3.x，它看起来更像：

  1. http.authorizeHttpRequests(
  2.       requests -> requests.anyRequest().permitAll())
  3.       .sessionManagement(sm ->  
  4.           sm.sessionCreationPolicy(SessionCreationPolicy.ALWAYS)
  5.       )
  6.       .csrf(csrf ->
  7.           csrf.csrfTokenRepository(new HttpSessionCsrfTokenRepository())
  8.       );

字符串
