在Spring boot版本3.0.+的Spring Security中，身份验证不起作用，并且所有POST请求都不起作用。
CORS策略已阻止从源“http：//localhost：3000”访问位于“http：//localhost：9090/api/rest/users/auth”的XMLHttpRequest：对印前检查请求的响应未通过访问控制检查：请求的资源上不存在“Access-Control-Allow-Origin”标头。
然而，GET请求工作，并没有给予这个错误。所有建议工作在3.0以下的Spring boot版本。类型https://reflectoring.io/spring-cors/不工作。我使用REST配置与JWT Token实现WebMvcConfigurer。
我已经尝试在请求的前端和后端的响应端连接所有推荐的头，但没有任何帮助。显然，问题是在这些版本的非常小的。谁遇到过这个问题并解决了它，请回复。
