Question

当我尝试到达休息时，我发现了有关预检的错误。

错误XMLHttpRequest无法加载http://localhost:8080/hello。响应预检无效（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授权资本化，但它仍然给我错误。

过滤

@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");
}
