spring cloud微服务分布式云架构Spring Cloud Zuul

Spring Cloud大型企业分布式微服务云构建的B2B2C电子商务平台源码请加企鹅求求： 三五三六二四七二五九

POM依赖

                    org.springframework.cloud            spring-cloud-starter-netflix-eureka-client                            org.springframework.cloud            spring-cloud-starter-netflix-zuul            

启动类加上: @EnableZuulProxy 注解

配置:

spring:  application:    name: zuul-gatewayeureka:  client:    service-url:      defaultZone: http://localhost:9001/eureka/server:  port: 9501zuul:  routes:    #把order-server服务映射到路径/my-order/**    order-test-route:      serviceId: order-server      path: /my-order/**  #过滤指定的url,即不路由指定的url  ignored-patterns:    - /*/order/list # 当hystrix的值小的时候，hystrix生效，当ribbon.ReadTimeout小的时候，ribbon生效    # 注意：只有zuul路由是url是才生效# 如果使用的是serviceId 需要使用 ribbon.ReadTimeout 和 ribbon.SocketTimeout）hystrix:  command:    default:      execution:        timeout:          enabled: true        isolation: #命令的执行超时时间  超时将执行回退          thread:            timeoutInMilliseconds: 8000ribbon:  ReadTimeout: 10000  #读取超时时间  ConnectTimeout: 10000

ignored-patterns 为忽略指定的API

自定义过滤器需要实现ZuulFilter接口:

/** * 用户访问时触发 * * @author 阮胜 * @date 2018/7/19 21:48 */@Componentpublic class TokenFilter extends ZuulFilter {    private static final String TOKEN = "token";    /**     * 过滤器类型     *     * @return     */    @Override    public String filterType() {        return FilterConstants.PRE_TYPE;    }    /**     * 过滤器在过滤器链中的位置     *     * @return     */    @Override    public int filterOrder() {        return FilterConstants.PRE_DECORATION_FILTER_ORDER - 1;    }    /**     * 返回值为true时执行过滤器,false则不执行当前过滤器     *     * @return     */    @Override    public boolean shouldFilter() {        return true;    }    /**     * 用户访问时触发该过滤器     *     * @return     * @throws ZuulException     */    @Override    public Object run() throws ZuulException {        RequestContext requestContext = RequestContext.getCurrentContext();        HttpServletRequest request = requestContext.getRequest();        String token = request.getParameter(TOKEN);        if (StringUtils.isEmpty(token)) {            requestContext.setSendZuulResponse(false);            requestContext.setResponseStatusCode(HttpStatus.SC_UNAUTHORIZED);        }        return null;    }}

/** * 用户访问完要返回的时候触发 * @author 阮胜 * @date 2018/7/19 21:57 */@Componentpublic class PostFilter extends ZuulFilter {    @Override    public String filterType() {        return FilterConstants.POST_TYPE;    }    @Override    public int filterOrder() {        return FilterConstants.SEND_RESPONSE_FILTER_ORDER - 1;    }    @Override    public boolean shouldFilter() {        return true;    }    @Override    public Object run() throws ZuulException {        RequestContext requestContext = RequestContext.getCurrentContext();        HttpServletResponse resp = requestContext.getResponse();        resp.setHeader("auth", "test auth");        return null;    }}
