但有一个错误：

{"error":"access_denied","error_description":"Expected CSRF token not found. Has your session expired?"}

请告诉我怎么了？？ 多谢各位

从SpringSecurity4.0开始，默认情况下使用XML配置启用CSRF保护。如果要禁用CSRF保护，可以在下面看到相应的XML配置

<http>
  <csrf disabled="true"/>

更新：请将您的代码更新为新的java配置，这很容易理解和配置。

对不起，我是java新手什么是新的java配置？请阅读以下内容：如果您喜欢此视觉视图：：www.youtube.com/watch？v=-4BQXNufpbQ
