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

<dependencies>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-netflix-zuul</artifactId>        </dependency>    </dependencies>

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-orderorder/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:

@Componentpublic class TokenFilter extends ZuulFilter {    private static final String TOKEN = "token";        @Override    public String filterType() {        return FilterConstants.PRE_TYPE;    }        @Override    public int filterOrder() {        return FilterConstants.PRE_DECORATION_FILTER_ORDER - 1;    }        @Override    public boolean shouldFilter() {        return true;    }        @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;    }}

@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;    }}
