java - @CrossOrigin(origins = "*") 在 Firefox 中不起作用

Question

在我的 Controller 类中，我指定了@CrossOrigin(origins = "*")，我正在尝试连接我的角度应用程序，但它不起作用。我知道这是因为 Angular 在 4200 端口上运行，而 Java 应用程序在 8080 端口上运行，但是有什么方法可以做到这一点吗？不部署 war ？

@CrossOrigin(origins = "*")
@RestController
public class UserController {
//
}

1. 如果您使用 Spring boot

CORS support is disabled by default and is only enabled once the management.endpoints.web.cors.allowed-origins property has been set.

同时根据CORS support in Spring Framework

If you are using Spring Security, make sure to enable CORS at Spring Security level as well to allow it to leverage the configuration defined at Spring MVC level.

还有一个问题可能是 CORSMIssingAllowCredentials

If the request is being issued using XMLHttpRequest, make sure you're not setting withCredentials to true.

火狐 Does not support CORS for resources which redirect
