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，我会收到403响应。

XMLHttpRequest无法加载http://localhost:8080/login。没有请求中存在“Access-Control-Allow-Origin”标头资源。因此不允许来源“http://127.0.0.1:9000” 访问。响应的HTTP状态代码为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，以便在没有CORS和CSRF问题的情况下使用angularJS？

Answer 1

您需要在Web安全筛选器之前按正确顺序添加筛选器，如下所示：

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

Answer 2

@CrossOrigin(origins = "**", maxAge = 3600)

可以解决问题，但我认为这不是一个非常可靠的解决方案。到目前为止，我发现我的某些端点可以使用它，而某些端点仍在提供CORS错误。尽管如此，对于大型项目，我仍然是一个快速技巧，我认为设置CORSFilters是必经之路，我相信这是您正在尝试做的事情。
