当我尝试访问休息 api 时，我遇到了关于预检的错误。

错误 XMLHttpRequest 无法加载http://localhost:8080/hello。预检响应无效（重定向）

我制作了那些我需要的过滤器，以便从另一个端口提供的 javascript 访问 api。我猜他们是罪魁祸首。我尝试添加授权以及大写授权，但它仍然给我错误。

筛选：

@Override
public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) throws IOException {
        responseContext.getHeaders().add("Access-Control-Allow-Origin", "*");
        responseContext.getHeaders().add("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
        responseContext.getHeaders().add("Access-Control-Max-Age", "-1");
        responseContext.getHeaders().add("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization");
}
