Spring WebFlux添加WebFIlter以匹配特定路径

Question

在Spring启动应用程序的上下文中，我尝试添加WebFilter以仅过滤与特定路径匹配的请求。

到目前为止，我有一个过滤器：

    @Component
    public class AuthenticationFilter implements WebFilter {

        @Override
        public Mono<Void> filter(ServerWebExchange serverWebExchange,
                             WebFilterChain webFilterChain) {
        final ServerHttpRequest request = serverWebExchange.getRequest();

            if (request.getPath().pathWithinApplication().value().startsWith("/api/product")) {
               // logic to allow or reject the processing of the request
            }
        }
    }

我想要实现的是从过滤器中删除路径匹配并将其添加到其他更适合的地方，例如，从我到目前为止读到的，SecurityWebFilterChain。

非常感谢！

我也许是一种解决问题的更简洁方法。它基于UrlBasedCorsConfigurationSource中的代码。它使用适合您需求的PathPattern。

@Component
public class AuthenticationFilter implements WebFilter {

    private final PathPattern pathPattern;

    public AuthenticationFilter() {
        pathPattern = new PathPatternParser().parse("/api/product");
    }

    @Override
    public Mono<Void> filter(ServerWebExchange serverWebExchange,
                         WebFilterChain webFilterChain) {
    final ServerHttpRequest request = serverWebExchange.getRequest();

        if (pathPattern.matches(request.getPath().pathWithinApplication())) {
           // logic to allow or reject the processing of the request
        }
    }
}
