vue-admin-template与nginx，springboot出现的跨域问题

Question

使用nginx代理时出现的跨域问题，

Access to XMLHttpRequest at 'http://localhost:9001/eduLoginController/user/login' from origin 'http://localhost:9528' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
request.js:55 errError: Network Error
xhr.js:178 POST http://localhost:9001/eduLoginController/user/login net::ERR_FAILED

Answer 1

springboot有没有做一下跨域拦截器或者过滤器配置，定义一个CorsConfig类实现WebMvcConfigurer然后加一个注解@Configuration交给springboot
