Spring Boot CORS 403 请求的资源上不存在 'Access-Control-Allow-Origin' header

Question

我正在学习使用 Spring Boot 1.5.2 作为服务器和 angularJS 1.6 作为客户端开发 RESTful 应用程序。当我尝试使用“localhost:8080/login”从“localhost:9000/login”登录时，我不断收到 403 响应。

XMLHttpRequest cannot load http://localhost:8080/login. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:9000' is therefore not allowed access. The response had HTTP status code 403.

@SpringBootApplication
public class Main {
    public static void main(String[] args) {
        SpringApplication.run(Main.class, args);
    }
}

如何正确设置 spring boot 安全性以允许它在没有 CORS 和 CSRF 问题的情况下与 angularJS 一起使用？

Answer 1

您需要按照正确的顺序在 Web 安全过滤器之前添加过滤器，如下所示:

.addFilterBefore(
    new LoginFilter(new SimpleCORSFilter()),
    UsernamePasswordAuthenticationFilter.class
)
