Question

我正在尝试评估zipkin，以便为我们所有的微服务启用分布式跟踪功能。以下是我的设置中的版本。

Spring-boot版本： 1.5.7.RELEASE
spring-cloud版本： Camden.SR6
zipkin版本： 2.2.1

application.properties

spring.sleuth.sampler.percentage = 1.0

spring.sleuth.web.skipPattern =（^清理 |。。。+图标）

我创建了ZipkinSpanReporter bean，如下所示。请注意，我已经将Eureka服务器设置为所有微服务甚至zipkin服务器注册了Eureka服务器，以便Zipkin客户端可以通过eureka解析zipkin服务器

 @Bean
    public ZipkinSpanReporter makeZipkinSpanReporter() {
        return new ZipkinSpanReporter() {
            private HttpZipkinSpanReporter delegate;
            private String baseUrl;

            @Override
            public void report(Span span) {

                InstanceInfo instance = eurekaClient
                        .getNextServerFromEureka("zipkin", false);
                if (!(baseUrl != null &&
                        instance.getHomePageUrl().equals(baseUrl))) {
                    baseUrl = instance.getHomePageUrl();
                    delegate = new HttpZipkinSpanReporter(baseUrl,
                            zipkinProperties.getFlushInterval(),
                            zipkinProperties.getCompression().isEnabled(),
                            spanMetricReporter);

                    if (!span.name.matches(skipPattern)) delegate.report(span);
                }
            }
        };
    }

我观察到的是，当我检查zipkin时，zipkin客户端（书）没有将所有跨度报告回zipkin服务器。据报道，几乎有一些跨度掉落

我已启用日志记录

logging.level.org.springframework.cloud.sleuth.instrument.web=DEBUG
logging.file=book.log

以下是日志信息：

但是我找不到从zipkin控制台登录book.log文件的traceId

请问您解释为什么没有向zipkin服务器报告多个跨度？

提前致谢。

很可能你的代码被破坏了。您可以查看https://github.com/spring-cloud/spring-cloud-sleuth/blob/master/spring-cloud-sleuth-zipkin/src/main/java/org/springframework/cloud/sleuth/zipkin/ZipkinAutoConfiguration.java课程，了解Edgware我们已经添加了负载均衡的zipkin服务器分辨率。

使用baeldung教程中的代码示例是否正确？（http://www.baeldung.com/tracing-services-with-zipkin - 3.2.Spring Config）

我认为第34和35行（结束大括号）有一个错误。

我通过修改这样的方法解决了这个问题：

@Bean
public ZipkinSpanReporter makeZipkinSpanReporter() {
    return new ZipkinSpanReporter() {
        private HttpZipkinSpanReporter delegate;
        private String baseUrl;

        @Override
        public void report(Span span) {

            InstanceInfo instance = eurekaClient
                    .getNextServerFromEureka("zipkin", false);
            if (!(baseUrl != null &&
                    instance.getHomePageUrl().equals(baseUrl))) {
                baseUrl = instance.getHomePageUrl();
                RestTemplate restTemplate = new RestTemplate();
                zipkinRestTemplateCustomizer.customize(restTemplate);
                delegate = new HttpZipkinSpanReporter(
                        restTemplate,
                        baseUrl,
                        zipkinProperties.getFlushInterval(),
                        spanMetricReporter);
            }

            if (!span.name.matches(skipPattern)) {
                delegate.report(span);
            }
        }
    };
}

也许这有助于某人或baeldung的某人阅读此内容，并可以验证并更正代码示例。 ;）
